Tire Question (Page 1/2)

Five years ago I put new tires on my 87 base coup. From then to now I have put about 7000 miles on them.
now I need two new ones for the back, the front still look new the back have almost no tread left.
Do they eat tires like that or is it some thing to do with the suspension? I had the local GM dealer do a four
wheel alignment at the time.

That is unusual wear if they are normal 300+ wear tires. Sounds like you may have an alignment issue.

could this be bumpsteer related or bad tie rods, I know the rear suspension is complicated to say the least.

Tire wear ratings tell you little about a tires expected life amongst other brands. The tire wear rating is only relevant within a manufacturers line of tires.

I have bought TWO replacement sets of rear tires without wearing out the fronts...Apparently, the light loading on the front tires simply doesn't wear them out- The rears carry more weight PLUS deal with.....ahem......Acceleration....

I have ended up replacing the fronts simply due to age.

Can you post a photo of the worn treads?

Ever since I have been driving Fieros, I wear out at least two sets of rears for every set of fronts.
Every. Time.

That's been my experience for the last 25 years too.

Kendallville, you need to have the alighnment checked. Wear on the outside of a rear tire isn't common.

Nice wheels! 😉

Thanks for the responses . What gets me is the wear is even across the tire, not just inside or out.
I even try to keep a light foot so it wont eat tire like my firebird did
