Finally got rid of the stock Goodyear's and replaced them with a set of Cooper at3 4s 115T...same size as stock 275/60/20...Driving home they feel a little bouncy if that makes sense. My stock Goodyear's were always around 37-39 PSI...the shop put these on at 45 PSI..could that be the cause?

If it says 39 psi on the door jam then thats what i would go with 45 psi is a little much and adjust psi when tires are cold

I just looked at Discount tire website and max pressure for that tire reads 44psi. I would look at the sidewall max pressure. Driving adds another 4-5 psi. That would put you at 50psi. That would certainly explain bouncy. Nick
