Tire Question-finding a size

Riding Again

Guest
After reading the volumes about replacement tires, I'd like to get some Avon Roadriders. However, it seems that the front tire comes in a 90/90-19 or a 3.25-19 (about an 82mm by the math).:mad:

My current tire is a 100/90-19 and would like to keep something similar.

Anybody with sources for a similar tire or equivalents to match? I guess I could go with the similar Pirelli Sport Demon, prices are similar.:-k
 
I have the same dilemma, the M26 road Riders also offer a universal tire (front and/or rear) in 100/90-19. I was going to use that, but i don't really know what the difference in tread is from their dedicated front tires...

Don't worry about it. The Roadrunners are great tires by all accounts and unless you plan on riding in the rain all the time, the tread pattern is not all that important anyway.
 
i second nessism. i actually just recently got a pair of tires from avon for my bike, the front is a roadrider am26 100/90-19 i haven't put a ton of miles on it, but it feels great, even in rain.

not to mention Chris@flatout sold'em to me for 150 dollars for the pair and that included shipping! they were here in a couple days.

might wanna check www.flatoutmotorcycles.com and/or give chris a PM or call (he's a member here.)

That sounds like a pretty good deal - although I've had some "iffy" shipping from them in the past.

Do you mount your own tires? I haven't tackled that yet, mainly because I'm afraid I won't get them balanced well enough...

Plan on taking that shafty for some speed runs are we?

Balancing between a couple of jack stands works pretty well, at least good enough for sane speeds on the road. I agree that's a pretty good price for the tires. I'm going to drop Chris an email and ask if I can get a similar price.:D

i have in the past, but i don't have a garage or anything really resembling useful tools where i live now. fortunatly the local stealership only charged 20 dollars each to mount and balance them.
 
I was thinking about getting the roadriders also. Is 100/90-19 stock size? And What do you suggest for rear tire size.

Stock size is 3.50 - 19, but 100/90 is the best fit for more modern rubber.

130/90 is a good size for the rear of an 850 - stock is 4.50. Rear rim is 2.50" wide for the 17" rear so a 130 is about right.

BTW, sent Chris an email. I'll let you guys know what he says.:)
 
Thanks for the input! If you would be so kind Nessism, let me know as well.
 
Yes, the 100/90-19 AM26 is a front/rear application, so is often listed separately from the dedicated fronts and rears. It has a direction arrow pointing one way for front use, and the other way for rear use.

As it happens, I've found that this tire is quite durable, and you can easily go through 2 rears for every front, with no bad habits or odd wear developing in the front. With other tires, I've always had to replace both at the same time. So the Avons give excellent performance and are quite economical.


The other point is that modern Avon tires come from the factory in perfect balance. There are no balancing marks and no need to mount the tire in a particular position.

Simply clean the bare rim, then balance it carefully before you mount the tire. As long as you stick with Avons, you'll never need to balance again.

I didn't believe this at first, but after mounting 7 or 8 sets of AM26 RoadRiders on various bikes, I've found it to be true.

Here's the 100/90-19 mounted on the front. Looks nice, no?

Here's my high-tech balancer setup made with rollerblade bearings. It looks crude, but is extremely sensitive -- you can get far more precise results with this than the shops can get with their computer balancers. It just takes a little longer. The spin balancers save time and take little skill to use, but they are actually less precise.
