When I had 7.50x16's mounted to my wheels I took them to a truck tire shop I have dealt with for years young kids looked at them didn't have a clue but I knew one of the older persons in the shop he did them for me while the younger kids watched hopefully they learned something so I can keep going there as it is close although the older person said I always bring in the hard stuff anyway nothing wrong with the old wheels if you can find a good shop.
