I heard that if you run much over 18 or so psi you "will make short work of balding them in a hurry?" Is this true? Interco website says 30psi max psi... whats the deal? If I had 36x.12.50 SX what psi should i run for daily driving on a 16.5x9.75 rim? Also, how good do these wear and perform on the street? this is gunna be 80% on the road and 20% in mud and sand but i really like the agressive look.
