I have a 22’ Ram 2500 with the Cummins, 4x4 and looking for suggestions for replacement tires. It currently has the 275/70r-18’s on it. The Firestone HT’s it came with. They are holding up quite well but I rotate them about every 6k miles. My truck is a pavement queen and the only off roading it sees is my gravel driveway and the occasional gravel campground. I have been looking at the Michelins and the Cooper HT3s. The Firestones are wearing well but they suck even on dry pavement and ride like rail car wheels even with the air pressure let down to 50 front and 35 rear. We do some towing (sometimes a lot) with our 7k TT. I thought about going up to a 295/70-18 with a little taller sidewall but haven’t seen anyone running that particular combo. What are some of y’alls thoughts on this? TIA
