Bmw E90 Xi Fitment Issue

Hey guys,
So I bought a set of 255/35/19 for the rear
PZERO

And a set of 225/35/19 for the front
Ironman (cheap brand )

Somehow I still experience traction control kicking in whenever I'm driving slow and or making turns ( not all the time but I'd say 40 % of the time )

I am completely clueless now..

No idea what to do.

Should I go back to Canadian tire and just cough up another set of 225?


Here are the dimensions of the rims
RIMS 269

Front:
19X8" offset +37mm

Rear:
19X9" offset +39mm



Any help would be appreciated! Thank you

Shouldn’t your sidewall in the front be bigger? Stock is 225/40 fronts and 255/35 rears

You would want 255/30 for the rear.

Check out this excellent thread on XI staggered tire calculations:

Yeah it should. But I assumed that 35 on both would work! And it is a 2010 BMW 335i e90 xdrive

Yeah! So assuming I get another tire with 225/40/19 should fix the issue? Does it matter if it's not pirelli?

No, that won't work either. You need to keep the rolling diameter within 1%. If you are looking to run 225/35 19 front and 225/40 19 rear, you have a difference in rolling diameter of -3.4% (I think I'm doing this right...). You need less than 1% difference front and back in order to not have issues.

Definitely read up on the thread I linked above (XI Staggered Tire Calculator). It will show you what you need.

Effectively, you should just buy the proper rear tire sizes to match the front, which is 255/30 19.

Yeah I checked it out.
My issue is that I already have the 255/35/19

I can't return it :/


Would it work if my fronts were 225/40/19

Would it rub on the suspension? Is it doable?

thanks for the help!

Sadly, I don't think it will work. It looks like doing 225/40 front will leave you at a difference of 4.2%.

EDIT: I must be wrong above. I think 225/40 should work. Not sure what I had in the calculator to get the 4.2%. Ah, I had 255/30 it seems. My bad.

I'm using this site to compare: https://www.tacomaworld.com/tirecalc...0r19-255-30r19

Look at the Revolutions Per Mile percentage which I'm focusing on. It's not exactly the same as rolling diameter, but I think it can help for specs not listed in the thread I linked before.

I also don't know if 225/40 19 will rub. I'm running stock 18" staggered myself. Sorry.

Oh, and extra duh. We have fantastic tools right here on the site. Go back to the main page for Wheels and Tires and right at the top you have a more robust tire calculator/comparison tool.

It will be perfectly fine as far as diameter differences are concerned. It will likely rub a bit though.
