Anyone running 10 ply's? If so, how do you like the ride? Just installed 275 65R 20 Michelin LTX- A/2's, I am wondering if these tires will be too stiff in the winter? I am completely happy with the ride so far. They are much more stable than the Goodyear SRA junk tires. I have them aired to 45 psi and was told I can air them up 80 psi if needed. I ran a couple of back roads to test them along with a couple hard pack gravel roads and I have to say they are awesome! No more darting on anything less than pavement anymore, the truck feels totally different, amazing what new tires will do to transform a vehicle. Going on a long 2 week trip with the TT soon and I was pretty skeptical about the SRA tires in the heat, empty truck they were okay, but wasn't looking forward to pulling my TT with these. Now I can't wait. Please comment if you run 10 ply's, I would be interested in your feed-back.
