2008 Prius at 30660 miles I bought three weeks ago Goodyear Integrity tires wearing out 5/32 now

No Goodyear will do nothing. You weren't the original buyer. They didn't do the alignment. You set the tire pressure. They have nothing to do with your driving style. Maybe 6 other reasons I could come up with.

As for the CPO aspect, they measured it at the time of inspection prior to sale. Did they measure the alignment? Are all tires wearing? What pressures are you running? Is the wear uniform?

I once had a car lot switch tires on me between the time I drove it and the time I picked it up the next night resulting in an accident 4 weeks later and 300 miles later.

 

So you will need tires at the next service - that's 5,000 miles from now. They should be good until 3/32.

 

Tread depth measurements aren't accurate. I've had tires gain tread between visits. If you want the tires to last they have to be inflated to max sidewall pressure. Even at max sidewall I still got some edge wear on the set on my 2006.

The tires that come on a new car have a very minimal warranty partly (mostly?) because the manufacturer pays relatively little for them and they may not be made to the retail specifications.

 

Of course, the tread depth matters most in the rain. The difference in stopping distances can be startling. In this test, you would still be traveling 55MPH on 2/32 tires and 45 on 4/32 where you'd be stopped on almost new tires.

Tread pattern matters too. On tires optimized to handle rain and evacuate water from under the tread patch, I could easily travel safely at speeds where other cars were sliding and slowing. But they were sure noisy.

All tires are compromises. Of cost, handling, wear, stopping, rain, perfoamnce in the cold, etc.

Unfortunately, the Goodyear Integrity has horrible and I mean horrible wet braking performance, in a Tirearack test they stopped some 20+ft. Further than the other tires.

 

Good Year Integrity aren't real tires, they're specifically designed to make Toyota more money when they sold brand new Gen2 cars back in the day, but they aren't as good as even modern economy tires made these days. The only good thing about them is they show that the previous owner was good at making sure the car was kept to the same specs as it was when it was brand new.

PS: Careful on tire pressure in the rain... I bumped the Integrity's up to 50psi when I first got the car and every pothole and puddle, especially at freeway speed eliminated 98% of the traction for a brief moment. SCARY!!! I run 'em at 42/40 psi now... I can't wait till they're finally worn out and I get real tires!

Recommend michelins with highest number, Costco rotates for free and adds nitrogen when needed. They check. All for free. Love Costco policies and their tires.

 

I'm certain that his tire problems have been resolved by now. Most likely wore out the replacements too.

 

Yes 5 years is a long time as this thread is from 2013. Plus the OP has not been on for 42 weeks. How do people find threads this old?
