265/30 vs. 275/30 on 20x10" and 295/30 vs. 305/25 on 20x11"

[suspenceful]

Anyone have pictures of 20" wheel/tire setups?

I'm looking at a set of 20x10" ET20 fronts and 20x11" ET35 rears for my F80.

I'm torn between the following:
265/30/20 front 305/25/20 rear
275/30/20 front 295/30/20 rear

Haven't really found anyone running these exact setups on 20x10" / 20x11". Just 19" setups or stock 666M setups.

For starters

A. What brand of rubber are u leaning towards? as the sidewall will vary

B. Are u dropped or stock suspension

275/30 on a 20x10 et20 won't fit...

That's a 265/30 PSS on a 20x10 et20

If I go with 275/30 and 295/30, Kuhmo ECSTA PS91 (~$600)

If I go with 265/30 and 305/25, Pirrelli or Michelin (~$1500)

I'm lowered on EMD springs (1.45" F / 0.75" R)

I'm new to the platform, so excuse my ignorance. What part of them won't fit? Too tall? Too wide? Rub on strut or fender?

I found these two threads:

See my pic above and just be aware the F80 has less clearance then the F82.

Since ur dropped on springs I personally
would go with MP4's
265/30/20
295/30/20

That just looks really stretched to me. But I am definitely finding that 265/30 is a lot more common in the front, not a lot of people running 275/30 so there must be reason.

PSS BMW Spec are super narrow, the stretch front / rear was almost identical.
I loved it back in the days but switched wheels.

I would go 275/30/20 up front and 295/30/20 in rear. This keeps the diameter front to rear similar to OEM (26.5" front / 27" rear) and will not have too much of a stretch look, if at all. You can also run a 265/30 up front, but diameter will be slightly smaller at 26.3". Not a fan of 305/30 for handling, and potential clearance issues. Don't run a 305/25. Diameter will be less rear than in front, and that brings up DSC issues.

For reference. A ZCP with 20's from the factory runs 265/30 - 285/30 and diameter is (26.3" front / 26.7" rear). Star spec PSS tires stretch alot more than general spec PSS and PS4S.

- 275/30 will not fit without modification at least camber on a 10" et20
- What's wrong with a 305/30 and handling? Did you run this size?

ET 20 is an aggressive offset. I missed that. Nothing is "wrong", maybe I should rephrase my post, but I like to keep the stagger between front and rear as close to factory as possible.

I like my 305/30 20 together with my 255/35 in the front.

275 up front will rub
I'd stick to a 295 on the rear for a 11 wheel

[guess2098]

275/30/20 on 20x10 doesn't work. I tried 3 different brand of tires. Pss,ps4s, conti supercontactsport. None of them work

Good call on the 265's. I just bought an F80 ZCP with 275/30/20 PS4S on 9.5 ET 22 and they rub a fair amount. Not lowered. Will be swapping out the front tires in the next few days.
