Quick question,

fronts: 225/40-18
rear: 255/35-18

will this work with the 18" stock wheel?

THanks

 

as far as I've read here the widest you can go is 245.
for example a very common set up is 245/40R18

hope that helps

 

That is almost a 3% difference in rolling circumference...not sure if the ABS will like that. The 255's will fit on the rim OK...but why bother..go with the same front and back so you can rotate the tires.

If you truly want a staggered setup...you need staggered rims as well to pull it off with the right look

 

Reducing height on raear compared to front is not good.

 

That would be a good set up on all four wheels instead of going stagered.

 

that's a horrible setup on stock wheels

you want staggered tire setup, get staggered wheels with it too

 

Concur.

Go with 245/40's all around or opt for staggered rims (but keep the treadwall height consistent).

 

those are bmw spec on the 335i, understeer city!! and plus as everyone else has said the ABS will not like it and the DSC if equipped.

 

if you wanna go stragger, you can either do 225/45/18 front 245/40/18 rear or 235/40/18 front and 255/35/18 rear
