Will it Rub? Going from 265/30 to 275/30 on 9.5x20 +22 in FRONT

[maniz]

I have 265/30 PS4S tires installed on my Vorsteiner 9.5x20 +22 front wheels and will need to be replaced soon. I want to move up to 275 width because the current tires look stretched, plus the increased grip and slightly higher sidewall would be nice.

Will there be any rubbing issues? No spacers.

Michelin's recommended rim width range is 9-10" so that's not the issue.

Depends. F80 or F82? Lowered? Some f80s rub. F82s don't. Others with more info can chime in.

Forgot to mention. It is lowered on M-Performance adjustable springs; not a crazy amount, about 20mm IIRC. Car is an F82 as in my signature.

How much room do you have to the fender now? Try add a 5mm spacer and see if it fits. That would be the approximate increase in width (poke) that the 10mm wider tire would be

I'm really curious cause I have 20x9.5 +18 and wanna run 275 but I think it's gonna hit the fender

Just a heads up… we don't see your signature on the mobile app.

F82 might be ok? I know some dudes have to get camber plates to clear them. YMMV though.

The 275 width will still keep the tire inside the fender; there is plenty of gap from the fender's edge. My worry is mostly about the inner sidewall hitting the shock or fender wall in hard cornering and there's no way to check for that of course, so I wanted to ask here in case someone was already running that tire+wheel size/offset setup. I could always raise the front springs a bit to compensate for the sidewall height if I have to but I'd prefer not to.

You should be fine without spacers. 275/30 is slightly taller so if you add spacers down the road, you'll be hitting the fender liner at full turn. but no spacers, no problem. If you do hit the fender liner, just raise the car bit.

I forgot to update the thread. I can confirm that indeed there is no issue with that size + offset combo on the M4. I changed to it 3 weeks ago. I can't believe the shop I bought my wheels from way back when suggested 265; sidewall was way too stretched compared to how it looks now. And my wheels are right in the middle of Michelin's recommended width range for the 275. The slightly higher sidewall is more protective too. While the wheels were off, I did raise the car about 9mm to get to BMW's recommended height for MPHAS with 20" wheels...did not realize the shop had set them too low.

Doesn't matter what size you can fit on the width of the wheels. They're recommending 265 so you don't increase the overall diameter of your wheels. Your wheel speed will be off. And could have effect on traction control.

275/30 is about 1% more in overall diameter than OEM. Your speedometer reads 1mph higher.
