Getting ready to buy new tires (front and rear), getting Avons, liked them on my Roadstar so they're going on the RSV. Just wondering where everyone is getting them from nowadays. J&P have pretty good pricing, you join their "club", you get 10% off. It's $50 to join, but I'll end up with about half of that back with the tire purchase. The price is 139 ea on the tires. Southwest is about the same price and Motorcycle Superstore is about the same with the discount offered. Just wondering what people are doing. Thanks

Up here in Canada, we get royally screwed on M/C tires. I just bought a pair of Avon Venoms and they cost me $375ca. That doesn't sound too bad until you realize I got them 40% off on sale. And no, that's not mounted...

I take turns between JP cycles and Dennis Kirk. One time JP will be $30 less, next time DK will be $30 less. Depends which one wants to sell tires that month I guess.:think:

I just bought a set from Southwest Moto . I understand they just changed ownership but it's biz as usual. Buy two and shipping is free. You might want to compare prices for the second gens. The last set I bought was 3 years ago, and if memory serves me right it was about $25 bucks more this time around.

Ive been using SW moto but their shipping is only free if you buy two, which you are. I just tried www.tireexpress.com for my new avon up front as shipping was free over 100.00. Ill see how they are to do business with. Their prices seemed to be competative with SW moto.

My '83 Venture has MR90-18 on the front, and a MU90R-16 on the rear.

 

I am looking at buying a set of Elite 3's from Motorcycle Superstore, and these are the sizes they give...

 

Front: MR90H-18

Rear: MU90HB-16

 

Will these work? Does the "B" mean bias?

 

I want to stay Radial and tubeless.

I've priced tires at JP Cycles, their close to me. I just got off the phone with them and they don't give discounts on tires. He said their distributors give the lowest prices they can and won't reduce anymore. I bought mine from SWmoto and got real good prices even though one tire was the wrong one (Grrrr my fault too, I hate that. God Bless. Mike

I found the info here...good stuff.

 

 

How to read tire fitment charts and info:

Typical complete tire description: 120/70ZR17J (58W)

 

Now, let's break that down into pieces that make sense:

  • The first number (120) represents the widest point of the tire's width between the left and right sides, called the "section width", and measured in millimeters. In this example, the width of the tire is 120 millimeters.
  • The slash ( / ) is there to differenciate the first number from the second number, and serves no other purpose.
  • The second number (70) represents the sidewall height as a percentage of the first number (in this example, it tell us the tire sidewall height is 70 percent of 120 millimeters, or 84 millimeters tall).
  • Then comes either one or two letters (in our example, ZR). Sometimes these letters are placed elsewhere in the description, but traditionally, they should be listed this point. The first letter is always the speed rating (see Speed Rating chart), and the second letter, if it is there, is an "R" (radial tire) or a "B" (bias tire). Lack of a second letter means it is a bias or non-belted tire.
  • The next numbers (17) represent the wheel's diameter, measured in inches. In this example, the wheel is 17 inches across.
  • A letter at the end of the first part of the designation (the J in our example) is not required, but if present means that the tire has a special characteristics to match some manufacturer's specific motorcycle model. For example, Metzeler makes (made at the time I first wrote this portion) a Z4 radial as a 150/70ZR17, as a 150/70ZR17B, and as a 150/70ZR17J, where the "B" model was intended specifically the OEM factory tire for BMW 1150GS models (slightly different tread pattern), and the "J" model was intended for Yamaha FJR1300's (again a minor tread pattern variation from what I could tell).
  • A two digit number follows, which is sometimes omitted but never should be (58). This number represents the load capacity or weight rating of the tire (in terms of how much weight, including both the rider and the motorcycle itself, the tire is designed to handle as it's maximum). In our example, the 58 can be looked up in a cross-referenced chart, and represents a maximum load rating of 520 lbs. There is no simple way to directly convert the number to the weight that I have been able to figure out.
  • Finally, a letter may follow the load capacity (W). This is a manufacturer "modifying descriptor" and means that the standard for the tire is modified by some means (W generally means higher speed rated than a standard Z rated tire). We haven't been able to find a cross-reference for the various modifiers (yet -- they do vary by manufacturer), so if you are concerned about the rating modifier, contact the actual manufacturer's rep for the tire.
  • Additionally, all motorcycle tires are normally marked with three or four digit code on their sidewalls, which represent the date of manufacture (the first two digits are the week of the year, the last digit is the year of the decade it was manufacturered in). Since modern cycle tires are only good for about five years from the date of their manufacture (the time period it takes the various compounds that keep the tire pliable and strong to evaporate out), knowing which year of a decade it was manufacturered is normally enough. Example: 011 would be a tire manufactured in January (1st week) of 2001. 118 would be a tire manufacturerd in the 11th week (between the 13th and 19th of March) of 1998 (since 2008 hasn't arrived yet, as I write this). As a general rule, newer tires are better, and we recommend you buy tires manufactured within the past 12 months whenever possible (obviously, if you have a flat away from home, you will take whatever you can get). Do not buy a four or five year old tire -- and if you buy an old bike, immediately check the tire age before riding it!

SPEED RATING:

Speed Rating vs. Used Tires

Tire's speed ratings are established with new production tires. Tires that have been repaired (patched), abused (dyno-tested, used at a track day), or are worn down somewhat no longer qualify for their original speed rating. Keep that in mind when you try to figure out why the motorcycle's manufacturer specified a 149+ mph rated tire for a bike that only goes 130 mph max. It's for your own safety!

  • RATING RATED TOP SPEED MPH / KPH
  • J 62 mph / 100 kph
  • N 87 mph / 140 kph
  • P 94 mph / 150 kph
  • S 112 mph / 180 kph
  • H 130 mph / 210 kph
  • V 149 mph / 240 kph
  • Z 149+ mph / 240+ kph
  • SPECIAL NOTE: Tires with a 2" to 2.5" nominal section width (think choppers) are rated at 75 mph.

LOAD RATING:

 

The importance of the load rating on a tire can not be overstressed. 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!

WHAT ELSE TO KNOW:

  • NARROW VS WIDE: Although wide tires are all the rage now, narrower tires handle better under most real world conditions.
  • TIRE GROWTH: All tires will expand to some degree over time once they are mounted, both due to the pressure on them, and due to heating-cooling cycles. Street tires normally expand 3 to 8%, while race tires can expand up to 22%. Be cautious in mounting a tire that will barely fit your clearances; the tire may easily grow to exceed the available space once it gets up to temp.
  • UNEVEN TIRE WEAR (#1): Because roads are normally crowned to permit rainwater drainage, and you consistantly ride on the same side of the crown (right side of the road in the most countries; left side in the UK, Japan, and certain former British colonies), under normal street riding, tires wear unevenly to one side across the peak of their center apex.
  • UNEVEN TIRE WEAR (#2): Depending on a variety of factors, including the size of the land-sea boundaries, the compound composition, the ambient temperature and the road surface temps, tires may wear unevenly from the front to rear of the individual tread blocks. Tire pressure and how it relates to tire surface temperature can have a drastic affect on whether this kind of scalloping/cupping at the land/see boundaries occurs, although certain tires types do it more than others.
  • HIDDEN LEAKING: Your tires leak. Period. Under pressure, tires leak out some of their pressure directly through the rubber compound of the tire each and every day, very slowly. Check your tire pressure before you ride anywhere for the day (usually referred to as measured "cold") and add air as required.
  • PRESSURE DIFFERENCIALS: A ten degree (F) change in the ambient temp will result in a significant pressure change in the tires. If the weather cooled or got hotter since yesterday, check your tire pressure again before you ride.
  • NAILS, SCREWS, TACKS: If you get a nail, screw or tack in your tire miles from home or the closest shop, you have a few choices. The wisest of them is to call a ride to tow you & the bike to somewhere where you can get a new tire, then pull the object once you get there and hope it didn't go all the way through. The second is to cut it off flush (if it isn't already) and ride it to a safe place slowly -- very very slowly (think walking pace), ready for a possible leak or blow-out. The third is to pull the item out and pray it didn't go through -- and if it did, you're not going anywhere without a tow. And the final way is to carry an emergency patch/plug kit, pull the item, plug it as necessary, then proceed directly to somewhere that sells replacement tires.
  • TIRE AGE: Motorcycle tires should not be used after five years from date of manufacture. Tires contain Volitile Organic Compounds (VOC's) which help keep the rubber flexible and grippy; as tires age, the VOC's leach out. Certain conditions can accelerate this process, including extremely hot and excessively humid or dry environments, parking on certain forms of man-made carpeting, certain molds & mildew forms (which may accelerate or even cause what is commonly known as "dry rot"), as well as overheating the tires due to low tire pressure or hard use.

Southwest Moto seems to be the best I found until recently...

 

http://www.jakewilson.com -$10 when you buy 2 or more tires

This is a kick off of Rocky Mountian ATV/MC which I purchased most of my motorcross gear, and accessories due to the selection and great prices. I checked the other day and surprizingly the Big bike tires with the -10 off for 2 are $2-5 cheaper than Southwestern moto. Free shipping for orders over $100 and you get credit back based on amout you spend with them for the year. I got over $60 last year I could credit on an order.

They do not have a big selection on the website for a lot of big bike accessories but are gaining everyday. They have a good reputation with me for I have been buying from them for close to 5 years for motocross. Some of the sites listed in previos post...most of the time I have a really hard time finding exactly what I want quickly and prices do not match what the catalog says on some of the stuff. Tires is pretty easy to find...but look for a Chain tention idler for YZ250F. You will waste a lot of time looking.

 

One thing for sure...you have to watch all websites to get the best deal. I to have notices prices going up and down from week to week and month to month.

 

I am trying to decide if I am gonna pull the 404's off prematurely (only 4K now) to get some Avons or E3's installed to improve on the handling of Black Betty.

Ron Ayers is the cheapest, but they charge $12/tire shipping, which makes them more expensive in the long run.

 

It looks like I'll have to go bias...hard to find radials in my size.

Update on my order: I ordered a new front tire from www.tireexpress.com on a Sunday online. The UPS guy was delivering it that Tuesday. Tire Express is a division of Competition Accessories, whom I have been doing business with for years. Total price was 147.00 with free shipping. It does appears that unless some company is offering huge discounts then most tire suppliers prices will be pretty close in the same ball park when you figure in shipping and in some cases, taxes.
