Ok I have a 96 Suburban K1500 with a 5.7 and I drive mostly on the pavement but live on and frequent many places on some rough dirt roads and unimproved roads tow very little but do carry extra weight. I looking at getting some new tires and many places are telling me that the regular tires are ok to run (they are 4 ply tires) but then the door sticker says LT tires and those are 8-10 ply and the shops are telling me that they will ride rough. So what would be consensus? I have had 8 ply on two other vehicles and didn't think they were bad but have not had them on a Suburban. Also is it worth $150 more for life time rotation and balance and road hazard? I can buy a tire cheaper than the extra cost of these options.
