Tire Sizes on what appears to be stock rims

[kizer]

In the Jeep world a lot is based off the tire size to determine the Lift and the axles to insure they are not to weak.

I know my 65 is a bit different in that its not an off roading machine and its not going to be subject to the same abuse.

Anyways whats the going tire size for what appears to stock rims on a 65 6 lug?

Currently I'm rolling on what appears to be low rider wheels and well its driving me bonkers.



I'm sure there is a factory size which would be great to know, but I'm also interested in whats the largest I could fit. I'd really like that fatboy look opposed to my low profile look.
