Btw- if u guys drive a lot of gravel - that's the issue a lot of folks don't realize. The anti-rock chipping stuff is in some specific tires- not others. Designed for gravel. I have 3500 duramax.... my lady duramax I got less than 10k miles on set of Coopers without rock chipping stuff in em. Switched to a tire that has the anti rock chipping and pry get 5x the mileage. U can research which tire has it. My duramax now has 15k on a set and they don't look worn one bit. 100% id be buying 10 ply tires on anything. I got sick of flats and put 10 ply on jeep, truck, etc. hardly any flats. Run nice and all have anti rock chipping stuff made in tread. They are "E" rated but works great for my smaller stuff too. 10 ply!!
