Windy,
If it's not too much trouble could you post a diameter measurement of the 18" tires? I'm running 8X17.5's (stock on my '62 one ton),at 30.5" tall,and with my current axle ratio I'd like to find some taller wheels and tires for it. New 17.5's will cost me about 130.00 each,so if I can get taller rubber for about the same money I might as well. Thanks!
