Would 305/70/16's work on my 99' 4x4 with cranked T-Bars and the originial chrome ford rims?? Would there be any rubbing???

Thanks

 

Yes they would fit and work. However the OEM 16x7 inch wheels are slightly narrower than recommended for a 305mm wide tire. If you are gonna keep the OEM wheels forever, a 285/75-16 would be a better fit. They are also 33 inches tall, but are an inch narrower than 305/70-16's. Usually, running a tire on too narrow a wheel can cause the center portion of the tire's tread to wear slightly faster than normal, similar to running too much air pressure.
