20" Wheel / Tire OEM Fitment Question

kromix · 11-17-2015, 10:19 AM

So I'm going to get some 20's they are:

20x9 et 35
20x10.5 et 45

What tires would be the absolute closest to OEM? My guess is:

235/30 in the front
275/30 in the rear

or should I go 285/30 in the rear?

Thanks

235/35-20 and 275/30-20 has almost identical diameters, both about 1% taller than OEM size.

235/35 and 275/30 will look a bit stretched on 9" and 10.5" wide wheels though.

So any recommendations then on tire size for that wheel?

245 will fit without issues up front.

But I dont think you should go wider than 275 on the rear wheels to avoid rubbing.

You might consider 245/30-20 and 285/25-20, 1% shorter than OEM size.

But you need to confirm that rear fitment since it's a very aggressive setup.

The 235/35 and 275/30 combo is probably your best option after all.

I run 245/35 with 275/30 without issues. You can run 285/25 or 295/25, but will depend on how low you want to go and the tire is getting pretty thin for my tastes and wheel protection.

I think once the fronts need replacing I will look at possibly a 245/30. Get a little lower profile since I like to tuck a little more up front. Picture included so you can see the profile.

Maybe consider 245/35 and 285/30, especially if your car is equipped with xDrive.

275 will rub on dips and if your hauling people expect rubbage

Well, all OEM BMW wheels has a 3-digit identification number called the "Style".

Your wheels are style 356.

The 11-digit numbers you provide are BMWs part numbers, which is good to know when you order the wheels from a dealer.

We dont ever use the style # at the dealer, so im not use to using it. So use to useing the last 3 of the part number.

Hi,
My car came with 225 35 20 front and 255 30 20 rear.
I want to change them with all season and get 225 35 20 front and 275 35 20 rear Continental DWS.
Would that still be ok (rear)?

.BMW. · 12-29-2015, 03:54 AM

OEM or aftermarket wheels?

The OEM rear wheel is only 8.5" wide, the maximum recommended tire is 255.

Mhnd198502 · 12-29-2015, 11:21 AM

OEM.
So 275 would be too wide?

It may be possible to fit a 275 on a 8.5" wheel but I wouldn't recommend it and it's 20 mm wider than the tire manufacturers allows.

Mhnd198502 · 12-29-2015, 09:52 PM

The PZero i have on the car look horrible.
I need to get wider tires for the rear. Just that i have to find out the max size i can go with for the 8.5 rim.
