Just bought my '07 335i sport pkg with some 19s on it. With only me in the car I can hear rubbing in the rears on hard launches / acceleration. With a passenger it gets more pronounced and easier to trigger, and with 4 people it's basically impossible to accelerate without hearing massive, abrasive rubbing towards the rear.

No idea what the rims currently are, except that they have a BMW center cap and look OEM -- can anyone name them from the attached pics?

Anyway, they're wrapped w/ Hankook Ventus V12 Evos, 235/35/19 front, 275/35/19 rears. I tried measuring the rims w/ the wheels on the car and best approximation bead-to-bead is maybe 8.5-9 front and 9.5-10 rear, hard to be accurate with them mounted. The tires had about 42psi.

The previous owner says the car wasn't lowered, but then there were 2 owners before him. Not sure how to handle this, the rubbing's driving me nuts

According to the Miata Tire Calc I'm running 0.7" taller in the rear than stock, but is that really enough to cause such massive problems? Suggestions towards a fix?

Have those fenders been rolled? Looks like its rubbing right at the top of the "V12 evo"?

I could be wrong but by the info so far, maybe more roll or pull on fender.... or a little more camber.

Put tape on the fenders and chalk on your tires to see where it is rubbing.

It's probably the corner near the bumper. You can roll it a little bit or sand it down.

From the picture, they appear to resemble our VMR V713.



If it is, the wheel (in 9.5" width) would come in an offset of ET22, ET33, or ET45. Our typical recommended setup (no rubbing) on your car is 9.5 ET33 with 265/30/19

[Scottycs]

running 265/30 or 255/30 would help.

[Rodny]

You should able to see where exactly is rubbing by removing the wheel/tire.
I cant tell from the pic but do you have spacers?

[Momukhamo]

HMM have your fenders rolled

hmm i have 265/30 19X9.5 REAR WITH 10MM SPACERS i can hear a slight rubbing just 1 tire tho left side. and it looks like its rubbing against my fender liner im lowered though..

im planning to get alignment first because i just got my coilovers installed a few weeks ago. i hope they can tell me exactly where my wheel is rubbing..

hoping i dont need to roll my fenders.

Thanks for the replies, here are mine.

Just got the car, not expert enough in fender rolling to know if they've been rolled. But I'm assuming they haven't since it's rubbing so hardcore and suspension is supposedly stock.

What would I be taping / chalking -- any instructions on how to do this?

Any way I can confirm this? Is there something on the back of the wheel or anywhere that would confirm it's yours?

Help or solve it entirely? Don't wanna drop $400+ on tires just to have less-pronounced rubbing.

I don't know if there are spacers. Is it easy to tell from the outside?

Just take chalk and mark up the side of the tires where you can tell its rubbing, then go drive around a bit and when it rubs, stop and check to see where the chalk mark is on the fender or bumper. If you keep driving, theres a chance with more rubbing that the chalk marks will be gone by the time you get home.

Either remove a wheel, or look inside to see if you see something between the wheel and the hub.

[bmw325i]

If you take off the wheel the offset should be stamped on. Or you could post a picture of how flush they are.

I had 9.5et33 with 275/30/19 and no rubbing before my fenders were rolled it was close. 9.5Et22 with no stretch and without a roll would rub quite a bit.

[raceyBMW]

Take it somewhere to get rolled if you haven't done it before. When you try and roll it it will crack the undercoating and you should recoat the areas. It will probably be like $40 a side.

For the rubbing issue, the wheel offset makes a big difference. I had 275 width rears that didn't rub with ET38 10" wheels, but stepped up to 285 width tires and they rubbed. Got a slight fender roll done and that took care of the problem...that will be the cheapest solution for you if you want to keep the wheel/tire setup you have.

[MonacoBlueE90]

Your biggest issue is the wrong aspect ratio rear tyre you have 275/35/19 and it should be 275/30/19 which really will make difference wheter it rubs or not. You can check the wheel size from behind the spokes.There should be the width and offset. Offset can be marked with something like ET.. IS..

[shadow191]

Cheapest option is rolling the fenders. They don't look rolled at all and it looks like it's rubbing right by your bumper/fender seam. Pic looks like the paint is getting jagged in the 2nd pic. It's pretty common, lots of people post about it. That should take care of your problems and if you do decide to get new tires, go with a 30 series sidewall.

[EMITTR]

Running the same set up with 19x9.5 ET 22 front and 19x10 ET 26 rear - same tires but 235/30 front 265/30 rear. Offset is what is causing me to rub even with fenders rolled. The outside wall of your tire is discolored and very shiny at the top near the tread compared to the rest of the tire and goes completey around the circumference - that is where it is rubbing. You can probably confirm this by rumming your fingers just inside the fender along the arc and feel for rubber particles. Classic and telltale - just like mine. So...I am going to LTMW to have the fenders (rear) pulled, might have to go to a 55/30R in the rear and 25/30R in the front and or raise the car slightly. Prior to this I had no problems with the 235/30R front and 265/30R rear both with 35 offset and my fenders were not rolled, pulled, shaved. Prior to this I did have rubbing with 275/30Rs on the rear and went to 265s and that took care of it.

Offset is the culprit here.

Good Tool this!

Ha, I didn't catch that, if he is indeed using 275/35 then yeah, those are the wrong aspects to match up with stock.

YES!!

According to the tire calculator at the top of this forum, if your specs are correct, your fronts at 235/35/19 have a diameter of 25.48 inches, while the rears at 275/35/19 are at 26.58 inch diameter, over an inch taller. This is over 4 percent difference front to back, when the acceptable allowance is more like a 1-2 percent max difference.

Speedometer issues also abound. With the current setup, your speedo reads 62 mph, but you are actually only going 60 mph.

Best recommendation would be to drop the rears to 275/30/19. The fronts would still remain at 25.48 inches in diameter, while the rear diameter would drop to 25.5 inches, a mere difference of .02 inches or less than .07 percent.

You will have more room in your wheel well and won't have to roll the fenders, unless they are at an offset of less than ET25. Tire brands also play a part, with some tires meatier than others.

I used to have 235/40/18 Front, 265/35/18 Rears when I had Hankooks, but had to revert to 225/40 Front and 255/35 Rear when I switched to Michelin Pilot Super Sports! The 219M wheels on my vehicle have a front offset of 29, while the rears have ET23, which occasionally rub.

With Hankooks:


Ultimately, it is your call.

[Eat.Sleep.Race]

you need 265/30 rears.

[Gary@TireRack]

Agree with the others that the rears are too tall.

[slay2k]

Thanks for the responses guys, much obliged.

Got into some shit with the dealer today, so gonna be a bit busy dealing with that before I can address the tire rubbing

[slay2k]

Sooo, better late than never right? Here's a follow-up...

Took the passenger rear wheel off and inspected the wheel well. First off, it's a 33 offset according to the back of the wheel, and 19x9.5 size. The wheels sit pretty flush with the side of the car, maybe a little toward the inside.

On the inside of the wheel well, about 2 inches up from the edge there are rubber markings and shininess about an inch tall spanning almost the entire arch of the wheel well.

The previous owner obviously put the wrong tires on the rear, and I know the solution is to get a couple 265/30s, but those are like $250 each so I'm wondering if I should roll the fenders instead... any thoughts?

[shadow191]

Rolling the fender may not fix the issue entirely. That's a tall tire and sits much closer to the fender. You can try the roll to see if it fixes it. Won't hurt anything, if it doesn't resolve the rubbing, time for new tires.

[gtaccord]

Getting the 265/30s will definitely fix the issue. As some others said, rolling the fenders may not.
