Wow a lot of obviously no nothing about big rims. Anyways a Donk is a 71-76 Impala/ Caprice, a Box is a 77-90 Caprice/Impala, and 91-96 are Bubbles. 80s Regals, Monte Carlos, Cuttlas' are G-Bodies. But to the point, some 245/30/22 should go on there without a lift and look real clean. That's what size tire am I going with in a lil bit.
Also he is right, 20s in FLA, unless you are RUNNING (also known as having a real powerful motor), is pointless. No one even looks at 20s lol. No one looks at spin kits either.
And did this guy just say something about 40s? Wtf? I hope your talking about 40" tires not 40" rims. Biggest production rim and tire are 30".
