I had good luck with sams club buying tires. I bought a set and they come with road hazard warranty from sams, at 5/32nds they got a nail out in the middle of the tread which they said couldn't be repaired, so they replaced the whole set under road hazard. I usually wait until they have the 80 dollars off 4 tires and then mount and balance, with all the tires warranties, free as a promotion. this promotion is currently going on. if you are a prime member you get the mount and balance for free, no prime is 10. per tire.
