well i have my good ol' trusty ADR DTMs and I don't really want to buy new rims so I was thinking of just putting as much sticky rubber on them as I could but I don't know what the rule of tumb is...............I know I can't go too wide in the front so I'll most likely keep my 225's in the front but I want to know how wide my tires can be in the rear....

 

You could probably put some 18x8s on there, no problem.

Damn ricers....

j/k

 

widest i think is 245 , pretty sure though

 

yeah, prolly 245s, it'd be tight though. Definetly stick with the 225s on the front.

 

I have 225/50's on mine and they look nice and flush. I have seen 245/55's but I wouldn't recomend it. Besides unless you are putting down tons of power/torque you wouldn't need 245's.

 

i'll stick with my 225's........thanks............

Check TireRack's site. They have a lot of fitment info. IIRC, max width on 7" rims will vary slightly with the tire manufacture, but I've never seen anyone that would go wider than 245. And FWIW, I think you'd want to go with 245/45 (not 245/50) to keep overall diameter the same.

 

On an S5, anything wider than 225's in front will rub the spring.

 

Hmmmmmmm.............perhaps I might need to go 245 in the rear once I get the BNR stage 3...............thanks for the input gentlemen.
