I serached around in the tire forum, but couldn't find a definite answer. I want to get a set of proxes 4, but I am worried about rubbing issues since I am riding on progress springs. I was thinking about getting 225/45/18, but I need to know for sure if there will no rubbing. Also, if you think a different side will be more comfortable I am open to other TOYO options (I have a good deal on Toyos).

As of right now I am riding on Kumho ECSTA Supra 225/40/18 in the front and Kumho ECSTA ASX 225/40/18 in the rear. The ride is really rough. Thanks.

I'm getting Toyo T1R's this summer, 245/35/18 I think. Shouldn't have any rubbing issues...

I asked the same a few months back and you could go with 235/40/18 and no rubbing........

235/40/18 is ideal for wheels that are 7.5 or 8" wide. I have that size in the Proxes 4

Why should I get 235/40/18 or 245/40/18 rather than 225/45/18? Someone enlighten me.

BTW, if you didn't see my sig.... I am riding on 6th gen 18's

Because 225/45/18 is not the stock diameter replacement size, the proper size should be 235/40/18 this replaces the stock 225/50/17 or 215/55/16. Any variations affect your speedometer readings etc. Go with what you want I chose to go with 245/40/18 just to gain a little more rubber to ease the harshness while not deviating from stock by too much.

I can live with the speedo a little off. Basically is the fatter or taller tire going to be more comfortable.

why would you want skinny little 225's on a 8" wide rim?? More rubber on the road = better. It has nothing to do with ride quality.

For some reason he seems hell bent on the 225's

Actually not... I just want to be sure and get some opinions.

Not to hijack this thread, but I have a quick question...

I have stock 17's on my SE right now, 225/50/17. Could I put on 225/45/17 without any problems? Thanks!

no 235/45/17s are better

Hoooper

just like pontiac used to say "wider is better". however, since you said you wanted better ride quality which i assume means smoother, the 45 sidewall will be marginally more comfortable, and marginally worse handling.

you COULD do the 225/45 17, but like ^^^ said, 235/45 would be better. smoother ride and better for your speedo accuracy.

Will I notice any differece (smoother ride) between 245 and 235?

Stock 6th gens come with 245/45/18

Hoooper

the only difference between the 235 and 245 is tread width. the comfort part will change with the sidewall size ie 30, 45, 50...

I thought since there is more tire on the road, then there is more (wider rubber) room to absorb the shock..... or am I just being 'tarded.

Hoooper

its all about the sidewall. a 245 on a 40 sidewall will be more comfortable than a 235 on a 40 sidewall only because the sidewall is still a bit bigger.
