I just purchased a set of 20x9 with a 30mm offset and 20x10 rears with a 50mm offset what size tires should I go with for the front and for the rears. The guy at my tire shop recomended 255/35/20 all the way around and I thought that was incorrect.

On a side note - Ive got the car lowered with a set of Eibach pro kit.

Thanks!

 

255/35-20 front and either 275 or 285/30-20 rears. You can also do 275/35-20 rears, or even all the way around, but they are about 1/2" taller. The 275/30-20 are just a bit shorter, but much cheaper than the ideal 285/30-20s.

Go look on www.tirerack.com, you can order staggered fitments there, check the overall diameter of each particular brand (it's 27" stock, the 255/35 and 285/30 are as well).
