On a 16-inch rim, you need either 205.50.16 or 225.45.16.<p>Depending on the offset it can be paradise or hell. If offset is 25mm it will be perfect. Less than that might involve some rubbing if the car is lowered.<p>Try 205.50.16 on the front and 225.45.16 at the back.

Hey DO NOT put any 225 tires on those wheels, i have Borbet Type A's in the exact same size, they rub alot, and i have 225-50-16. The correct tires should be 205-40(45)-16 especially if u have the car lowered, even so i have the wheels on the car now and NOT lowered yet, and they rub, as well as the full turning raduis can't be achieved.<p>Just my opinion....<p>MIKE

I stand by my first statement.<br>225.50.16 is a set-up for 5, 6 and 7 series. This is what I have on my 5 and 6 series.<p>An E30 measurement is 205.50.16 and 225.45.16<p>205.40-45.16 is way too small.<p>If it rubs, it might be because of wrong offset, which should be 25mm.

I have Borbet type C (or is it D? 6 spokes anyway) on my '91 325i with Eibach springs (about 1.5" lower) and Bilsteins. Tire size is 205/50R16. Works great, no rubbing. Big handling improvement over stock 14" wheels. And it's not any harsher on bumps. I put Kohmo's on the 14" wheels for track use. While the grip is much better, the car is better balanced (less understeer) with the 16" wheels with AVS Intermediates! I would not put larger tires on the rear because 1.) these cars don't have enough power to need them and 2.) it will increase understeer.
