if you get tires that are 20mm wider than your factory tires, and you still have your factory suspension, be ready to hear some tire rub.

in all the months that i've driven on my 225 tires with my coilovers, i've only once ever hear tire rub... i wont say where i was, or how fast i was going.

but today, i took 'the scenic route' to get home after work, and i was being very mellow versus how i'd usually drive that sort of road. i was given an unexpected dosage of tire rub on the factory suspension. SUCKY.

so yeah...

 

hah good advice. wow 20 mm makes a difference eh.

 

Two words, negative camber

 

camber doesn't matter with stock suspension. if you put more negative with camber bolts you're going to hit the strut even harder.

 

that is so true... im just glad that i have jic coilovers on the stiffest settings so i dont rub when i run my 245/40/18s. but when i run 225/45/17 tires for snow they never rub!!!



** oh and i only have 1 camber front and 1.1 in the rear

 

There is your problem. Maybe throw in a fender roll as well...

 

wait.. so camber adjustments are there to fit wider tires... wow... and all this time I thought it was for handling...


good info from Joel though...

 

I run 235/40/17 BFG KDW's on my stock 17x7 rims. 11k miles. No problems ever.

 

hmm, so you mean anything greater than 225 on an RS/WRX? Stock on an STi is 225 wide, so 245 should be the limit without rubbing, according to this rule of thumb.

 

<----245's here and I've had 2 different wheels and 3 different tire brands with no problems at all. You just have to roll the fenders, easy fix.

 

Steve, is that WRX or STi suspension?

 

Well its the same exact chassis so why should that matter. Oh and I sold my old wheels with 245's to member for his WRX and he just rolled his fenders so that pretty much busted this myth.

 

I have WRX suspension on my STi (02-03), but also had the 245's with my old STi suspension, they are soo similar its not even funny. The fronts are identical (minus the spring rates obviously).

 

been riding on 225/45/17 with stock sturts and eibach coils since ive had the car and never heard such a thing

 

i forgot to say... my fenders are rolled all aroun and pulled all around. everyone who has seen my car in person can tell they are pulled n rolled... but my car also sits very low just past tire tuck.
