I have not weighed them but I carried a pair of each to my shed which is 400ft from the garage and I have to get a regrip on the early wheels and was tired after carrying them. I then carried the new ones to the garage and I did not seem as tired, mind you my arms were numb. The next trip was done with a wheel barrow. both sets had tires so that may have played a factor too. I can weigh an old one if needed on a postal scale. I do not have a new one dismounted.
