tri z tires

[tri z maddness]

i have 21x8x8 tires on my tri z now. im trying to find out if i can leave the tire on the front and put smaller tires on the back. but i dont know if it will cause any problem. :wondering:wondering:wondering

Smaller height I hope lol! Bike came with 22-11-8 on the back,assuming it's a 85. You can do down to a 18-9.50-8. But you would only wanna do this for flat track racing. For "atv" use, I would shoot back towards stock size. 21-8-8 is an insane size lol ! Your front is fine either way. Whatever your size, whatever side it pulls towards,let air out of the opposite rear tire till it tracks straight as an arrow.

i have a chance to get a atc 250 x.which is faster tri z or 250x

Low pressure tire gauges are cheap and the best way to get even tire pressure. I think the Z would be faster but I've never owned a 250x.

There's no such animal as an atc 250x that i know of. You're most likely looking at a 250sx, 200x, or 250r. The 250r is the only one of the three that will run with the tri z. Faster? Depends on what year, gearing, engine mods, etc. box stock i think the 85-86 250r is a bit faster than the tri z, but can't say for sure as i've never owned one.

they do make a 350x.
