I have 305's on stock trd wheels, but even a 305 is supposed to be on a 8.5-11" wheel and the 325 is supposed to be on a 9-12" wheel. This is straight from BFG so I don't know what your tires would say exactly. I'm not trying to say not to do it just telling you the facts. I haven't noticed any wear on the center of the tire yet. With the 305's I have, i can barely squeeze my finger between the tire and the UCA.
