thanks guys, I am pretty happy with these tires so far.
As for the thumping, did you ever get your tires balanced?? If you didnt I am sure that is where the sound came from. You will eventually get that with every tire if you dont get them balanced.
I never got them balanced since I purchased the truck in July. I've read so many posts on here that the Goodyears are so bad and can't hold a balance I didn't even want to waste the money to try.
