17x8 +45mm rubbing issues?
Hey guys,
I put some 17x8 Enkei RPF-1s on my TSX with a 45mm offset and a 235mm Falken FK-452, and I have some awful rubbing on bumps as the wheel/tire is pretty much perfectly flush with the fenders. It's pretty much said this would fit, which probably makes my car too low:
I'm not sure what to say otherwise, but I'm wondering if Edge Racing sold me +35mm offset instead, as a 17x8 5x114.3 +45mm isn't even listed on Enkei's own site. Is there any way to double check this? I couldn't find the offset anywhere on the wheel and the invoice said the offset was 45mm.

You probably should've gone with 225-45-17... check the stamp on the inside of the wheel to see what the specs are. That'll tell you whether or not you have a +45 or +35 offset.

Do note that I'm not running negative camber, though.

A mile drop would have allowed you to run the 235 without issue, but for maximum clearance on a much more lowered car, the 225 is the recommended tire width.
Using the big FAQ at the top of the page, right in the first post, which is supposed to be the "Master Guide":
Ideally, keep the offset higher than 42mm and you'll be ok. Several members are running 8" wide wheels with 235mm wide tires at 42mm offset and don't have any trouble with rubbing, even when lowered.
Anything bigger than a +/-2% difference is considered a mismatch and should be avoided if possible. Speedometer, odometer, and VSA/ABS systems can be affected by mismatched tire sizes.
235/45-17 .....4.2in .......12.7in ....25.3in ......79.6in ..............796 ..........-0.5%
If our master guide is wrong, then that should be edited, not someone told to redo their research. We should be able to rely on public, stickied information to be the truthful sources here. I've also searched, and I've also read just about every post to come through here on this stuff over the last few months, watching people with 19x8.5 or whatever else with +45 or +48mm offset say it works fine. Very few people have experienced issues. Using a wheel offset calculator and a caliper, the clearance given seemed to be fine as well when I checked myself, although I'll admit that then it was a tight fit.
To check for wheel-specific discrepancies, I started to find other guys running the same wheel at the same offset.
That aside, over at the other place there's some guy running 17x9 at 245mm wide in the rear on an Enkei RPF-1 at 45mm offset:

He even said he had no rubbing issues. Of course, he's only on Tanabe springs.
CCColtsicehockey used to have a thread on 17" Enkei RPF1s that he was selling because he didn't like the way they looked, but I can't seem to find that thread, either. There's a fair amount of even specific research where people said yeah, this should work. I'm saying it doesn't work well given my current setup and that's all, that way people don't end up with more work than they had expected. I'm going to raise the suspension back to something a little OEM-like, and then see if the rubbing issues discontinue, but I'm not sure if they will under hard cornering. I still think there's a good chance I will have to roll the fenders.
It's a fine common excuse around here to tell people they haven't searched when something doesn't go right, but I'm not sure if it's possible define fit as something that does not maintain similar-to-stock well clearance (i.e., does not rub on the fender lining or on inboard suspension components.) Perhaps the sticky should be revised to say something about specific ride height, or the maximum recommended size without negative camber and a larger drop to be 225mm wide or a 7.5" wide wheel.

I'm glad you figured out the offset.
Before I sold my 17x8 +35 rpf1s off my RSX (235/40r17), I mounted them on my TSX (stock in every way, lol) and they were 'overflush' with the fender. I'm sure if I had lowered it and ran 225's with a good amount of negative camber, they would have fit under the fender.
My suggestion would be to do a combination of fender rolling and running some negative camber. Or if you want to save some cash, go for the negative camber only.
if you had a better picture of where the tire sits in relation to the fender, I could probably provide you with a starting point for how many negative degrees of camber you would need.
Noticed your from Palo Alto, CA. I'll have to check out your ride sometime.
Good luck with whatever you decide to persue

Reviving this thread to ask Populuxe if he ever solved this and how? I am running 235 series FK-452s also on a 7.5" rim with Comptech/Koni suspension setup and I am getting occasional rubbing in the front. Any suggestions for that?
