Yep! The 305/30/20, though a shorter sidewall, is actually more like the factory sized overall diameter, so your speedo wont read incorrectly. I run 315/35/20 which is way oversized, just for the look, but my speedometer reads off by about 5%. Between the 305/30/20 and the brembo packaged 255/40/19, the difference is only 0.64%, which is very close to stock, so much so that it's a perfect fit. And YES, I'm that **** about fitment
