Michelins have always been expensive, but it seems like the gap is getting even wider. I'm thinking of getting a set but I can't find a deal anywhere, and not sure I can justify an extra $50 plus per tire for the LTX/MS2's.

I think we've had this discussion a few times, I've never seen that kind of mileage. I believe I've had 2 sets of Michelin LTX/MS, great tires and I got over 50,000 but nothing like 85,000. To be fair I'm not very good about rotating tires at the right intervals and do a moderate amount of boat towing in the summer so that affects tire life.

I still may go for them, plan to buy something in November before the serious snow files. Stock tires on my Tahoe are Bridgestone Dueler H/L Alenzas, they have a good ride, are quiet, but not enough tread left for me to want to run them in the winter.

Rob, do you run 40 psi cold? I've been running 38 cold, ends up around 41 after some time on the highway.

I'm going to stay with stock size tires this time. The vehicle is smooth and quiet and gets decent mileage so I don't want to mess with it.

I'm running 275/55-20's and the Bridgestones gain 2 psi for sure, and 3 on longer highway runs per the sensors. About the same on the stock size tires on my Liberty, no sensors so in that case I'm checking with a gauge after I get home.

How comfortable the ride is will have more to do with the selection of tires than the increased size, regular highway tires or all-seasons will be quietest, A/T tires will be a bit louder, mud tires very loud. The bigger thing to look into is gearing - I'm guessing you have 3.55 gears though not sure without more details from you. A larger tire will lower the rpm from current levels at any speed, and the transmission shift points will be "fooled" a bit. The result is less towing capability, less acceleration, and maybe funky feeling shift points.

I put larger tires on my '03 R/T with the 5.9, and didn't have any re-programming done. For me the lower rpm were a welcome change, I didn't mind the shift points, and it still towed fine but the 5.9 makes more torque and at lower rpm and I had the 3.92 gears.
