bad tires

Dancer · 03-18-15, 01:54 PM

My 2014 ATS with 16,600 mi. (I bought it in Oct. 2014 at 14,000 mi.) has 3 bad tires.
Dealer said front tire defective.
Back tires: one maybe driven low, maybe hit curb...
A friend, tire guy, said "dry rot" but dealer said no.
Is this unusual? Your comments would be appreciated.
Also, should I get 4 new tires, rather than 3?

A tire can look like it had dry rot if driven at very low tire pressure. It will cause cracking, but not dry rot. If would replace all 4 and have an alignment done. I would also make sure that I was aware of low tire pressure on the dash/ DIC. On my CTS I got 36k on the original tires, I check the tires monthly and rotate them every inspection. The original tires were Bridgestone wear rating of 240(UTQG) but I replaced the with Michelin Pilot Sports wear rating of 300 (UTQG). I have been very happy with them although they are a summer performance tire not an all weather.

It's pretty unlikely to have dry rotted tires on a 2014 vehicle.
You can check when the tires were manufactured. There is a date stamp on every tire like the one in this photo. The "3812" means this tire was manufactured in the 38th week of 2012.

Also, another tidbit of almost useless information, if needed, if there happen to be bubbles on your sidewalls.
Perfectly round bubbles are caused by a defective tire.
Oblong bubbles are caused by road damage (potholes)

I've pumped up the tires almost immediately after the low pressure message.
I didn't kick the tires when I bought the car.
Car's at the dealer, so can't check mfr. date.
I'm waiting for a call back from Cadillac.

Service manager said 2 rear tires "customer damage", therefore, not covered by warranty.
I've driven the car for properly inflated 2000 miles out of the 16600.
This is lousy news.
