Tire Sizing on 8.5/9.5"

Ordered some wheels that are 8.5" ET 26 and 9.5 ET 37. The recommended tire fitment is 235/35/20 (front) and 265/30/20 (rear) for Michelin PS4's.

I was a little surprised because the staggered stock set up on the M340i comes with 255's in rear.

Do you think these will be too narrow in the front? Debating going up to 245's for front but I've reached out to both tire rack and another vendor and they both came back with the above mentioned set up.

Any input/personal experience?

I've got 8.5 front 235/35R20
9.5 rear 255/30R20

Fronts are spot on however the rears are stretched. I'll go 275/30 come swap over time.

Okay good to know, feel more comfortable about pulling the trigger now. 275's will be nice and wide! That's what I had on my F30 335i summer set up

I'm not sure on the offset with mine, but I had to add 15mm spacers up front in order to achieve that flush look.

Best to wait until they're on tho.

235/35 and 275/30 will be perfect for you though

Thanks for the input! I'm going to move forward with placing my order on the 235/265's and grab the PS4's.

I'm reading some are only getting ~8-10k miles on these tires tho? I got over 15k on my PSS's on my F30. Hoping you get the same on the PS4's if possible?

You should go with 245 40r19 and 27535r20...its a guy on the forum with this setup and its looks great and no spacers.
