Flat Spots on Legacy Tires

[shibainu]

Legacy Station Wagon, purchased new in Sep 2000 and maintenanced IAW the manual; coming up on the 90K service. Purchased good-year all-weather with 80k tread warrenty at 35k miles on car. Purchased new good-year tires last year with 35k still on warrenty due to flat spots on all four tires. Good-year dealer said this indicated a suspension problem on the legacy (too soft). Subaru dealer did a suspension diagnostic (couple of hunded bucks) and said that suspension was just fine. Good-year told us to bring the car to them every 5k miles for free diagnostics and rotation. Just took the car to Subaru for other problem and was told that left front tire has flat spot across the entire tread on left front tire (approx 7.5k miles on the new tires and one rotation). Subaru is implying this a tire problem; goodyear is telling us a suspension problem and we continue to eat tires. Any suggestions or similar experiences?

Goodyear has a bad batch of tires and you bought some.Were they cheap tires?

Suspension won't cause flat spots.

Yeah that seems odd.

 

I replaced the mixture of Goodyear and Continental tires on my '99 with 4 new Goodyear Eagle RS-As. Never seen any flatspots from Goodyears. Must be a defect with the tires you have.

Launch (with tire spin) much?

I don't think that would do it, neither would a faulty suspension. It is either a defective run on tires or when breaking you lock the tires up for long stops. However I would hope each time you are into a good year or the Stealership that they are checking your tire pressure.

I did flatten tires though it was on a truck with WOT.

Seems to be either a case of bad tires or excessive braking with ABS disabled.

 

But the latter will cause a lot of other bad side-effects too and a bumpy ride.
