- TIRES:
What kind of shoes will the well-dressed XJ being wearing this year? Well, it's been said more than once that tires are about as personal as underwear, and there's a lot of truth in that statement (whether there is wisdom, also, can be debated though.......).
With the wide variety of black rubber donuts that are available for your steed, it's best to stop and consider a few major factors besides price alone when making such a critical decision........after all, your life literally rides on your tires (and only about 4 square inches of each tire at a time, to boot!).
1) How do you plan to ride? By this, we mean are you mainly an around-towner, a long-distance rider, or do you operate your bike just this side of the edge of sanity, and scrape pegs and other metals around every corner?
An honest assessment of what the majority of your riding style is will go a long way in determining what tires are going to be right for you. "Everyday" use and long-distance riding/touring benefits from a harder rubber compound and good rain dispersion abilities (assuming that you'll even take your jewel out in the wet!). And a harder rubber compound will give get you many more miles from a set of tires (figure 12 -15,000 miles on the front and 8 - 12,000 miles on from the rears on a hard compound tire).
Softer rubber compounds will grip like the devil, and allow you quicker, tighter, and more predictable carving of the twisties, but they usually handle poorly in the wet (or leaves, or gravel, etc.) and don't last very long (perhaps 8 -12,000 miles on the front and 5 - 10,000 miles on from the rears on a soft compound tire). In addition, tires such as these normally have a more "rounded" profile, so that the contact area of the tire with the pavement remains as large as possible when the tire is leaning over. "Cruiser" tires tend to be more "squared-off" at the top edge and is one reason they do not provide as much grip during aggressive cornering.
Of course, if that retro-appearance is important to you, we even offer old-skool, raised-white-letter tires for many models that convey a classic look to these timeless machines.
2) How much can I afford? Generally, the more expensive the tire, the better quality it is......we realize that there are exceptions to this rule, but like most other things in life, you get what you pay for. Be careful if you decide to go shopping for used tires----internal damage (too many potholes, resulting in fractured or ruptured belts, etc.) or other such issues may not be immediately apparent (or at all), and unless you know the history of the tire, well............
Also, you should be aware that tires have "date codes" cast into their sidewalls, and tires do have an expiration date (more or less).....and that's about 5 years from the date of manufacture. And it doesn't matter whether the tire is new and unused. Exposure to oxygen degrades certain of the chemical components in rubber that normally keep them flexible and "grippy", and so even an 5 year old brand new tire is a catastrophe waiting to happen. Tire date codes come in two different flavors, pre-2000 (3 digits) and post-2000 (4 digits) year of manufacture:
Pre-2000: 3 digits, with the first two being the week of manufacture (so these two digits can never be higher than "52"), and the third digit being the year of manufacture. Think of it as: WW/Y. So 3-digit date code such as "357" will mean the 35th week of 1997. Too old. Stay away. Save your money and your life........
Post-2000: 4 digits, with the first two again being the week of manufacture (so these two digits can never be higher than "52"), and the last two digits being the year of manufacture. Think of it as: WW/YY. So 4-digit date code such as "3507" will mean the 35th week of 2007.
3) What are the roads in my area like? Although this may seem like a silly question, certain roads (mainly on freeways) have "rain grooves" cut into them to help minimize water build-up on the roadways. While they may do a great job of accomplishing that, these grooves also try to "grab" and steer your bike, whether the roadway is wet or dry.
On front tires, there is a central, circumferential "guidance" groove on almost all street-bike tires. This groove helps to "steer" the bike straight and prevent wandering, especially at higher speeds----and it really works well. Unfortunately, it works really, REALLY well when it comes into contact with those rain groove cuts in a roadway............and a Battle Royale develops between your front tire and those grooves as they both fight for directional control of your bike. THIS IS NOT FUN and can be very dangerous.
So if your area has these rain grooves, or you like to ride off into far, distant, unknown sunsets where you might encounter these road cuts frequently, just be aware. To counteract this problem, some tires have either a "wavy", "zig-zag", or "interrupted" pattern to their central circumferential groove, which greatly minimizes this effect, but of course results in less of a tire-influenced "self centering action" than tires which have a straight and uninterrupted groove would experience.
4) Size does matter.....and bigger is not better or even safe on a motorcycle. Motorcycles are not quite like cars in terms of suspension dynamics.....mainly because you don't "steer" a motorcycle, you either lean it over or you put a greater pressure (via handlebar control) on one side of the tire or the other in order to change direction.
Motorcycle tires are thus extremely sensitive to the rim width which they are mounted on.......too big of a tire on a rim "squeezes" or "pinches" the tire, making the contact area either too rounded or deformed in other ways that result in a loss of directional control and cornering ability, as will too small of a tire (which tends to "flatten" the top of a tire). Our whole-hearted advice on tires is this: use the size that the bike manufacturer recommends, and like Goldilocks says, not too big, and not too small......unless you like twitchy, spooky, and unpredictable handling, that is. We all agree that really big, beefy tires look ultra-cool, but that misses the point. The original XJ rims are pretty narrow to begin with, and do not like larger-than-recommended tires to be stuffed onto them.
The correct tire sizes, load ranges, and inflation specs are listed on the sticker on the steering headpipe, or in your owner's manual (also listed below for reference). ALWAYS run the correct size tires, NEVER use a tire with a "load range" that is lower than is what is recommended (that's a trip to the hospital, or the morgue, just awaiting to happen.........), and always run the proper inflation pressures and check your tire pressures religiously. Tires leak air, oh yes they do, all of them, all the time.....even directly through the rubber itself. That is normal. You don't have to have a puncture of a bad inflation valve etc. to lose air pressure in a tire. Even a 10-degree change in outside air temperature will increase or decrease your tire air pressure.
NOTE: it is generally not possible to fit a larger rear tire on a stock rim on shaft-drive models due to interference with the driveshaft tube.
5) Where did my tire go? All about tire wear and life:
Besides mileage and tire "style" (soft or hard rubber compounding, as mentioned earlier) considerations, the number one killer of tires (besides potholes and locking your brakes!) is that worn out suspensions components----front forks and rear shock absorbers----will cause your expensive new tires to wear in both a rapid and an uneven, unsafe manner. If you notice that your old tires are worn unevenly side-to-side, or exhibit "feathered" or "scalloped" wear patterns, that's a sure indication of suspension wear, and needs to be addressed sooner, rather than later.
The generally accepted cause of front tire scalloping and feathering are incorrect compression and rebound settings . Incorrect compression results in scalloped, while incorrect rebound rates result in the "feathered" appearance.
Also, unbalanced air pressure in the fork tubes (on models so equipped) will cause uneven tire wear.
The next major factor is poor tire life expectancy has already been mentioned before, but here we go again: improper tire inflation pressures. Yes, it's a pain to constantly be checking them and inflating or deflating (adjusting) the pressures, but.............a necessary evil. And a cost- (and maybe a life-) saver, too boot.
One thing you can't do anything about, though: your front tire wears more on its left half simply because of the pitch of the road.....all North American roads have a slight "crown" to them and drop off from the center of the road towards the shoulders, in order to promote water drainage and object dispersion towards the shoulders. This slope causes you to actually be performing a very slight, unconscious but constant "lane-change" maneuver (to the left) that constantly wears on the left side of your tire.
6) Other factors to consider:
* Wheel bearings---inspect, re-pack, or replace when changing tires.
* Wheel....make sure it's not bent (measure the lateral and vertical runout), and clean off the inside of it where the tire bead seals against the rim......you'll need a "mirror finish" type of clean at this critical mounting point.
* Replaces the valve stems or the cores. The stems can leak thru their washer inside the wheel.
* Mounting and Balancing.....you can do it yourself. If you choose to have this work performed for you, then shop around. It will usually be much less expensive if you dis-mount the wheel and/or tire yourself.
We offer the special tools that you'll need to dismount, re-mount, and then balance your wheel/tire assembly. Here's a great how-to guide:
http://www.clarity.net/~adam/tire-changing.html
One issue to take into account when trying to balance your own tires is that some manufacturers provide a visual guide (on the tire itself) as to where the "light spot" is on the tire.
The following manufactures do mark the tire light spot via the following marks:
Bridgestone: a yellow ring.
Dunlop: a yellow circle
Kendra: a yellow dot.
NOTE: made by the same company as Cheng Shin brand.
Metzler: a red dot.
Pirelli: a red dot.
The following manufactures do not mark the light spot on their tires.
Avon.
Continental.
Michelin.
The following observations from user MiCarl sheds a few important thoughts on the issue of light-spot marks (or the lack of) that you should consider:
According to the Avon rep this is because they want to force people to balance them rather than just aligning the mark with the valve stem. I like to find the heavy spot on the wheel and align the light mark on the tire. This lets me balance with minimal weight added. With the Avon tires, you could end up with the heavy part of the tire on the heavy part of the wheel and need a lot of weight to achieve balance.
Avon recommends that if you go over 2 oz. of weight, then you should dismount the tire, rotate it, and try again.
I haven't mounted an Avon since I found out what's up with the marks. I'd assumed that they were such high quality the mark was unnecessary. Next time I mount one I think I'll balance the bare wheel, then find the light spot of the mounted tire, and then rotate it so it makes the most sense. I'll probably up my charge for mounting Avon's (and other non-marked tires) to cover the extra labor.Click to expand...

LOAD RATING:
The importance of the load rating on a tire can not be overstated. A tire that is overloaded beyond it's design limit will run hot, wear fast and may quite literally blow out on you. The load the tire is designed to bear also affects it's shape and construction -- if you think about it, a GoldWing tire is not going to look like a GSXR600 tire. The load rating the manufacturer sets as the spec for your bike takes into account extra loading for weight-transfer (loading up the front wheel during braking, loading up the back wheel under acceleration), so you can't simply go by the curb weight of the bike. Always check the specs for your bike before ordering tires, and make sure the tires meet or exceed the load rating requirements for that wheel on that particular bike. For example, if the load requirement for the front wheel is "58" (520 lbs max), then you can fit a 59 or 60 weight-rated tire in the right size on there with no issue, but should never fit a 57 or below!
PR NUMBER:
The designation, ply number, refers to the tire load index. The PR marking is now only applied by the Japanese standard (JATMA. European standards (ERTO) do not require motorcycle tires to carry a PR number. The Japanese standard can be compared to the European standard as follows:
4PR - normal version
6PR - reinforced version
The PR number does not refer to the number of plies in the tire.
UNDER PRESSURE:
David Bowie says:
Yamaha says:
Maintaining proper air pressures in your tires is critical for both safety and performance....always check your tire air inflation for proper pressures before riding!
NOTE: "Load" is the total weight of rider(s), cargo, and accessories (It does not include the weight of the motorcycle itself, nor the fuel, oil, etc.). “Cold” means the ambient air temperature before you begin riding; in other words, the tires (and the air inside them) must not already have been heated by previous riding, nor from being stored (for example) in a heated garage before riding on a freezing cold day, etc. “Sustained high-speed riding” means for longer freeway (etc.) riding conditions.

Of course, there’s always a trade-off between tire traction and tire wear, which varies mainly due to riding style and tire inflation pressure . Lower pressures will typically increase tire temperatures, which then will soften the rubber and increase grip. This increased grip will cost you greatly in terms of tire tread life (and gas mileage) though. And total load (weight) will also affect tire temperatures -- the more weight , the greater the tire temperature (and thus the better the grip, and the less the tread life……..).
You should typically increase tire pressures when increasing the load. A good rule of thumb is to adjust your tire pressure such that the temperature increase causes the front tire pressure to increase 1 to 2 psi over cold, and the rear tire pressure increases 2 to 4 psi over cold (so, you will measure the tire pressures before riding (“cold”), and then measure the pressures after 15 or 20 minutes of riding. If the pressure increase is more than the above, add more pressure. If the pressure does not increase then you are over-inflated.
Running the tire at the maximum pressure under all conditions means sacrificing grip when lightly loaded.
All of the above motivates me to remind you that you should always “dress for the slide, not for the ride”……..
- WHEELS:
Although many Yamaha wheels are visually similar, they do not always interchange, as bearing sizes, speedometer drive gear differences (front wheels), and other factors do not allow a straight-forward swap.

Rear Wheels:
NOTE: please note that the reference to "interchange" is used loosely: there may be differences in appearance (wheel style) as well as wheel size (diameter and/or width), as well as brake drum (and thus shoes) diameter. On shaft-drive bikes, clearance to the swingarm may become an issue when going from a smaller to a larger width wheel.
Wheels that are larger in diameter than the stock size wheel will typically reduce the acceleration of the bike, but may increase top speed. Conversely, going to a smaller diameter wheel than stock will increase acceleration, but reduce top speed.
Rear Wheel Removal and Installation:
Typically, the axle shaft can become seized to the brake drum or the bearings. Sometimes a bigger hammer is the solution, but review these threads before you buy a 30-pound sledgehammer:
