Honestly, I haven't put enough miles on them to notice any wearing issues. But, I talked to some pretty honest people at Discount Tire when I got them. And, although they do not recommend running the 305 on the stock rim, they told me that it would be ok as long as I took care of them, i.e. rotating and such. However, they did say not to go any wider than the 305 since it is kind of pushing it.
Thats a great looking truck man. I think I am about to order those tires and was wondering if you have had any problems running the 305/65 on the stock rim. I have heard both ways; that they are too wide for a stock rim and that its not a problem. Any unusual wear issues?
