sounds like that's the best combo... subscribed for photos!


see the following post from another similar thread with good results from PSS 265/35/19 F and 285/35/19 rear on stock wheels.

My personal rules for fitting tires to the 1M and F80 M3/M4 etc


1- Put as wide a tire as you can fit in the front.
2- Put as wide a tire as you can afford in the rear.
3- If you need to TURN , try not to exceed stagger of 30mm as you will induce even more understeer.
If you are looking for traction at the rear (ie. more important than the ability to turn ) even with just a stock tune, one must realize that you won't find grip until you go to a 285 section or wider at the rear.

For #1 above.. for a street tire.. realistically a 265/30/ 19 up front is about as wide as possible but will have some amount of rubbing. On a completely stock car.. the rubbing is minimal over certain bumps and turning when parking. 255 should fit with little to no issue.

For autocross, my favorite setup so far is 285/30/18 front and 315/30/18 rear... but that required wheels wider than 10" at the rear, and it did make the car more of a point and shoot (due to more understeer) than running 285/30/18 square. No problems getting the power down though!

in my opinion, the M4/M3.. with more torque than the 1M.. is **way** under tired at 255/275
