I ran on my stock M135 18x8.5's 265/35/18 on stock height with no rubbing issues. But the safe offset kept everything further in from the fender than an aftermarket offset. Here are what Falken FK452's looked like on these wheels:


I have ET45 on 19"x9.5 with a more rounded Toyo T1R tire. The tires are slightly tucked and i do get a tiny bit of rub if I have 3 or more in the car with me while taking a corner at hard lateral G's. The rub comes from the rear driver side and I think the tire is just hitting the upper fender well with the corner of the tire. ET35 is totally fine in the front at my height as I've never had an issue....I just hit the bump stop rolling over a massive speed bump a little to quickly which was probably not healthy for the upper strut tower.

Here are what a Toyo looks like with a 235/35/19 setup on an 8.5" which I believe can handle 245 or 255 no problem for next time but only with that tire sidewall shape:


For just the wheel stance of an ET45 19x9.5 here is a reference...

It's funny how my passenger side rear is a lower stance yet it never rubs. So I guess the wheel wells must be shaped different on the other side which has a higher stance but rubs on hard corners with weight in the backseat.

Here's a picture of the opposite side rear showing more tire definition so you can see the sidewall shape of a Toyo T1R is much more angled/rounded when using a 255/30 on that wheel. Side fender clearance is not a problem at all with the wheel at ET45, since I've rolled both sides moderately without flaring.


I have 10mm spacers for an ET35 rear to try out this season so I'll see how much rub I get with those on the driver's rear and how much I need to raise the back up to keep rub down. I really rather have 265's on the rear as I prefer a more squared off sidewall stance look but I know that with different models/brands of tires, sidewall shape will all be different so it's a fine line of what will rub and what won't.

So if you get more aggressive rear ET35's, I'd have to say you'll need to have a mild to moderate stretched look with a lowering job so the upper sidewall doesn't contact the inner upper fender liner. On standard suspension you'll probably be fine with just a fender roll which isn't a big job on a sedan. Coupes have a thick sealer gunk all inside the fender lip that needs to be cut out to roll/bend the fender up. Sedans have a very thin version of the sealer so the metal will bend up easy without removing the sealant. If you use rear ET45, you'll probably be able to afford a more squared sidewall which looks meatier especially if you lower a bit but don't tuck the tires as much as in my pictures as you risk some rub.
