Anybody running 20 inch wheels and rub when turning at certain angles on a slope?

I'm running 255/30R20 ADV7.1 wheels on OEM suspension on the front of my car and it rubs only when the steering is 3/5 turned in either direction and on a slight slope(I mean slight, only a couple degrees).

I am looking at coilovers to solve the problem, but I want to be 110% sure it will be resolved. I don't want to just keep running in circles trying over and over again.

Anybody have suggestions for me? I would really appreciate it!

the stock 245/35/19 tire has a diameter of 25.75in while the tire that you are running has a diameter of 26.02in, so the current tire is a little larger than the stock tire size. the solution is for you to use a slightly smaller tire. your rubbing issue will go away if you used 245/30/20

Thanks Montreal red! Will it fit on my rim though? I'm no expert by any means.

Hi bro!! It's not tyre size it's offset that's causing tyre to rub on wheel liner.

When I had my black P40 Fronts were 20x9 ET 28. Zero rubbing with KW coilovers

Then I ran 10mm spacer (ET18 and it rubbed slightly like you experiencing)

When I fitted silver P40 rim was 20x9 ET 20 zero rubbing

Both Tyres were 255/30/20

Call me to chat about it Mike

Hi Bob,
Nice to see you still around Hope you are enjoying your new X6M!
Thanks, I'll give you a call on Monday.
How do I resolve this problem without getting new front wheels made up?

Thanks Khalid and Slicer. I have sent an email, so we'll see what happens. My car will be off the road for a few weeks, but I'm positive about it.

At least I know what offset to run on the fronts now.
