ive tried searching and haven't really found a clear answer. I ordered some 21" wheels online, was wondering what size tires I was suppose to run. car will be lowered on H&R springs so would like correct sizes to minimize rubbing. TIA

not that i'll provide the exact answer, but you gotta provide your wheel specs. wider wheels need wider tires. if you got aggressive offsets, you'll need stretched tires to minimize rubbing too

Front: 21x9 5x120 35 mm offset

Rear: 21x10.5 5x120 35 mm offset

will 245/35/21 and 285/30/21 work on a lowered car?

Depends on how much you lower by. I'm looking at a very similar set-up with 21" wheels (except I intend to go for Front 255 / 30 / 21 and Rear 295 / 25 / 21) but my new off-sets will be much closer to the stock 373's. I think with 21 inchers' you will have to use a lower side-wall as 35 for the fronts and 30 for the rears will use up too much of the wheel well and will rub.

This is the size most people are using for the 21" wheels on the BMW.. When the car is lowered on the H&R's it's gonna be a gamble depending on the offsets of the wheels. 35mm should clear the rear, 40mm would be ideal. I don't think you're gonna have any issues with the fronts.

Fronts - 255/30-ZR21 - 93Y
Rears - 295/25-R21 - 96Y
