The Vision 81 19.5 wheel is 7.5 wide, can I put a 225/70R19.5 tire on this rim? or is the rim too wide for this tire.

I've been told a 245 19.5 will rub with the vision 81's.

Looking to increase the weight load of the tires and rims is my goal.

The other option I've been given is to go with a 225/70R19.5 tire and a steel 19.5 that is 6.5 wide.

suggestions please,,,
