They would be roughly 1 3/4" larger diameter than the stock size (205's) and a hair wider. Might vary slightly by brand but, a 235 is about 28.9" dia and a 205 is about 27.1" dia. No idea if the extra height will cause clearance problems or not. Hopefully someone who has tried it will chime in. The 235's will make your speedo show slower than actual speed.
