I have a 2011 Silvereado with a 3-5 drop and I have a 22X9.5+30 6X139.7 wheel. Right now I have 305 40 22 tires... looks great but catches good in the front. What size can I go with? It is a short bed, reg cab. Would a 285 40 22 work or should i go smaller? i just want to be able to fill in the wheel well the best i can. thanks alot for any help u can give .
