Its funny the weight on the fedex boxes for the new 18" wheels/tires listed the weights as 40/35 lbs. I just got an email about the wheels from fedex that listed the actual weights as 48.6/52.6 lbs. I weighed the boxes they came in and they wieghed about 3.6 lbs.
Best I can figure the new wheels/tires weigh 45/49 lbs compared to the stock wheels which wiegh 42/47 lbs, not bad, and like the 2-3 lb increase in wieght the seller said I would see with the 18" wheels,
