I bought tires today, NOT from Costco. I paid $307.50 total for 4 tires. Costco no longer carries the same tires I bought the last time ($368.71). But the cheapest set of tires from Costco is $430.00+.
I went to the tire store early Saturday morning. The air was crisp, guys were rolling up the shop doors, and I was the only customer there for a while. It felt good to be in that moment. Somehow, that moment made an impression on me. I guess I'm getting older and feeling sentimental over small things around me. I set there and enjoyed my coffee. Tires were installed in about 30 minutes.
They tried very hard to sell me extended warranty. But, I didn't buy it. I do not believe in tire warranty. If I understand correctly, they cover defected tires. So, if your tire is damaged, they will check your car first. If your car is not in perfect condition (bad alignment, etc..) then they will not honor your warranty. At least that's how I understand. I don't need tire warranty. Just keep a good spare tire. I have a brand new full-size tire as a spare.
My car has bad (old) struts. It will cost me $1500 to replace struts. So, I decided NOT to replace struts, but just bought new tires. I plan to buy a car in 1-2 years. hope it was a smart move.
