the widest tire I can recommend for you Subi is 225 but, there have been others that have used wider .... also the 45mm offset is too low .... you should use a minimum of 48mm offset

If you have the wheels that I think you have, then I have the same ones with 245/40 17 tires. If you want 235 tires, then 235/40 tires will be a little bit smaller than stock, giving you slightly better acceleration due to a shorter gear ratio. 235s should fit fine with those wheels on a sedan. You could go with 245/40 tires if you want, but you may have to roll the fenders in the rear.

kinda wanted to revive this thread...
i've done a search, and couldn't find an answer to this question:
would a wrx lowered 1.5" be okay with 17x8 wheels, +47 offset and 235/45-17 tires? i know that must be cutting it rather close for rubbing issues.
any info is appreciated
thanks!

No wonder every body (including myself) is confused about wheel fitment.

Another thread states
6.5" ....... +53 to +55
7.0" ....... +50 to +53
7.5" ....... +47 to +50
8.0" ....... +43 to +47

Yet above someone states
"45mm offset is too low .... you should use a minimum of 48mm offset" We are talking 8" here.

Oz racing states 53 for 8" if my memory serves me correctly. Or was it 51. Whatever, it matches neither of the other quoted statement of facts. I am guessing many fit it including others not previously stated. Is a matter of optimal. That is where I think the break down is happening. Somewhere someonw is running 245 tires on a 8.5 inch rim successfully. They would tell me it does not rub too I bet. Then you find out they have 750 lb springs.

I do not think any body has actually tried all fitments and actually kows. Very frustrating.

In the end I will listen to the manufacturer if they make a sube specific offset.

It sure would be nice to plunk down $3000 with confidence. Problem is worse with obscure rims and sizes.

I have wheels in 17*8 et45 and 235/40/17 S-03's, so let me speak from experience regarding the size alone. You would be better off running a 235/40/17 (what i use) than the 235/45. that would obviously be a taller (than stock) and heavier tire and as such the shorter 235/40 would be a better choice. Even for gearing reasons, the 235/45 would not be a wise choice.

With the 235/40/17 S-03 tires, I get *no* rubbing whatsoever on my sedan and i am lowered about 1" all around on custom rate gound control springs (medium rate 280f/250r #). I have -2.0 degrees of camber F&R as well. I have pics that show the various clearances when mounted and there is still ample room between the key potental rubbing points. I'll dig them up if requested.

cosworth: thanks alot, if you find the pics, if you could shoot them over to me i'd really appreciate it, just so i can get an idea... without camber plates, do you think that there would be rubbing?

ebeck: you're right, the general consensus is: confusion

I wouln't really listen to anyone unless they actually have the setup that you want to use. I have SEEN 255/40 tires on 8.5" wide 17" wheels with 45 offset fit on a sedan, but I don't have them. Cosworth and I have the SAME fitment wheels that you want. The 235/45 tires will hurt your acceleration, but maybe not noticeably. 235/40 tires might help your acceleration a little, and they most likely won't rub. I have 245/40 tires, and they barely rubbed in the rear. My car's lowered 1" with tein h-tech springs, which are the softest aftermarket springs there are for the WRX, so it is my educated opinion that 235/45 or 235/40 tires will fit without rubbing.
