I've recently bought a set of Breyton's without tires, and I'm wondering what profile/diameter tires I should run to avoid rolling the fenders if I can. I've got a 2004 530i sport package. The wheels are 20x8.5 with an offset of ET13 up front and 20x10.5 with an offset of ET26 in the rear. If anybody can shed a little light on what tire width and height I should run, it would be greatly appreciated.

Thanks!

updated with offsets..

Rear go 285 25 20 or 285 30 20 dont go 295 as it will deff rub on dips and when the car is loaded

Thanks mike. Any insight to the fronts?

Sorry front 245 30 20 thats what mostly every one runs around here

Thank you sir. I'm gonna grab a few more opinions before I purchase and mount tires.

Sorry about a thread hijack.
I've seen this being asked before, but never paid attention to it, until now...

If the fronts are 245/35 R19, the manufacturer recommends 275/30 R19 to rear. However, the 285/30 would be closer to fronts when it comes to overall diameter. I know most people are running this setup here and the difference is minimal, but can anyone see any threats if I went for 285/30 for rear? Except that there are less to choose from...

I'd appreciate a help here, thanks !

The issue with different overall rolling diameter wheels front and back is that there are sensors that measure wheels' rotations and report to the car's "brain" when there is a discrepancy. In which case, the car will try to compensate for that discrepancy. There is some play-room there, as people successfully run both 275/30/20 and 285/30/20 in the rear on staggered setups. Also, some people have gone 285/25 and even 295/25 with somewhat less success. I would recommend sticking to the 275/30/20 though, as that seems to be the setup with the least problems.

Now as to OP's offsets, I think you might have to roll those fenders, as those offsets are pretty aggressive. Hard to tell before you've got your tires and the wheels are on, but I'd be prepared to roll the fenders.

Antti, I'm not sure if I've answered your question with this post too, but if I have not - its bc I was too dumb to actually understand it LOL so, if I haven't answered it, ask me again

It's ok you answered pretty well!
I was just wondering if the 285 would rub easily compared to 275...?

v_therussian

depending on the offsets. In my opinion, with aggressive offsets like the ones OP mentioned and 10.5 inch wide rims, they'll rub. On 19s, might not be an issue at all.
