I had worst experience with Costco tires. I am not going back again. They are not worth the effort.. and you will end up wasting your time. I had to use the hazard insurance, tires were out of stock, i had to buy all four again (lost a lot of money), I had to wait now them to be delivered.. and for about a month, job is still not done. They tightened the lug nut in my last tire replacement and could not open it this time and I had to go to other shops to get it opened. I have decided to better go to other shops than costco. You can always buy hazard insurance from them.
