All,

Thanks for the feedback on widest wheel/tire combo on a E30 325i(s). Widest award is still open with 225/45 R16 the most common.

The best answer to my question came via the Tire Rack's BFG T/A R1 size guide with tread width specs.

Since I want a 16x8 wheel with the largest tire patch possible, I choose the 255/50 ZR16 for the rear. I will probably stick with 225/50 n the front (I will have to see how the ABS handles the difference otherwise disconnect which seems to be the way most racers are going at least with SCCA & Club racing.)

No other combination other than a 15x8.5 offers close to a 10 inch tire patch. I am willing to settle on a 50 series aspect since the 16 inch diameter cuts down the sidewall anyway.

Good thing I waited on lowering the car.

See ya at the track.
