Over Sides Tires

[3rd_Wish]

I was wondering..... any of u guys here running over sides tires on track?

& hows handling?

i'm current running 205/50/15 (205/40/17)

thinking to get 225/50/15 (205/50/17)

If you mean wider than stock tires, most of us are running the widest possible tire we can without protruding beyond the fender lip (illegal until StreetPrepared). 225's will definitely offer more grip than 205's, unless you're competing in a very lightweight and low power car where you really can't use the extra width of the tire effectively, in which case you're just dragging extra weight around the track. But generally speaking, the wider the better.

oww critical error there dave i thought we had to stay within the fenders....its gonna hurt when you see those 315's on the rear of my car :)

jk

255's will work good enough


answer to question...yes 225's are a very nice size tire...and there is lots of R rubber with that size as well...

i have 15 x 6.5 rims. if i put 225/50/15 in to my civic.

r that be okay!?!?

do i have to get 15 x 7 or 15x7.5 rims?

some 225's are wider than other (I know, it sounds strange but 225 Hoosiers are quite a bit wider than 225 Toyos), but you can get away with mounting most 225's on 6.5'' rims, they'll just be pinched a bit more than you'd ideally want. When I say pinched I mean the sidewall will be angled back towards the rim so that the sidewall "bows" out a bit. On a 7-7.5'' rim the tire will be stretched out more, so your contact patch is effectively larger, and the sidewall is more verticle and thus able to do its job a bit better. For your first year of competition I wouldn't worry too much over this issue, but eventually you may want to upgrade to 7-7.5'' wide rims to maximize your tires performance.

Cheers,
