Hey, have a 2008 128i convertible, looking to pick up some 19" CSL style rims
Sizes are as follows:

rear: 255-35-19
front: 235-35-19

all 4 tires are 8.5 wide

looking to keep suspension and fenders unaltered
does it look like these will fit on a stock 128i convertible?

thanks!

The specs you listed are tire sizes, not wheel sizes.

The wheels are 8.5 wide, not the tires.

You'll need a 30 profile tire in the rear.

What are the offsets on the wheels?

[cabriolet27]

sorry, yes you're correct

seller does not know the offset of the wheels

so 100% a 35 tire in the rear would not work?

the wheels/tire combo is a super good deal so I'm thinking of just grabbing them, and if they don't fit i'll just try and resell

thanks!

should also note these are CSL style M3 replica wheels on pirelli tires

Are you buying wheels from a friend or similar? Have them look at the back of the wheel. Typically the offset is there.

35 profile tire would work on the rear for an 18", but not a 19."

Without knowing the offset it's a shot in the dark.

Considering replicas are typically made in many different sizes and fitments, and Pirelli makes tons of tires in all different sizes and specifications, you have nothing to go on to try to figure it out unless the seller gives you actual information.

Thanks for your help
Went to check out the rims, looks like both front and rear
Are ET44
Tires are pretty bald anyway so would need to get new ones, so could go for 30s on the rear

Would 19x8.5, ET 44 all around fit on a completely stock 128i?

You'll be fine. That 35 rear tire will likely rub the fender pretty good as it'll be fairly tall. Might even be outside of the 3% diameter change tolerance? Not sure. I'm sure there's a calculator out there that will tell you, or math, which I don't feel like doing this second.

Do you have the M-sport suspension? or 128i suspension.

[cabriolet27]

ok great thanks!

yea will have to be all 4 new tires, so will take your advice and go for 30 in the rear

I just have a stock 128i suspension, nothing has been changed on this car

128i stock suspension rides higher than the stock M-sport/135i suspension so you'll have even more room than most.

Happy to help.
