The 73-77 GM A-body-particularly the Chevy Laguna-is known for its large, tank-like body, huge wheelwells, and bulging wheel arches, so the smaller performance tires that fit Chevelles, Ca-maros, and Novas just don't look large enough for the proportions of the car. Looking through various manufacturer tire size charts, we quickly came to the conclusion that we needed something along the lines of a performance sport truck tire size. General Tire makes a very good one-the Cross Contact UHP (ultra high performance)-in a 275/55R17 (UTQG 420 treadwear rating, AA traction, A temperature), which fits a 17x9 rim perfectly, and has a 28.9-inch diameter and an 11.2-inch section width. That's a tad taller than our old 275/60R15s, and about the same width.
