Tires: Chevrolet Blazer 2000 -Uneven tire wear, alignment problem, correct torque


Question
This will be the 3rd time in about 4 years that I have had to replace tires on my vehicle. This is the problem. My front drivers side tire wears completely on the outmost edge and the rear tire on the drivers side wears in the middle. The mechanics do an alignment, tell me everything is ok, and then in about 6-8 months, I have the same wear on these tires. I'm not sure why I keep going back to the same shop, except I don't have too many options, because I live in a small town. This last time they looked at it, they said this happens a lot with 4WD vehicles (but I don't even use 4WD on my vehicle) so I'm not sure what they were referring to. I have an appointment tomorrow, and I'm almost positive they will tell me that these tires are not safe, recommend buying new ones, and then they will align them again and I will go through the same same thing all over again. This is really getting frustrating for me. Is there something that could be causing my tires not to stay aligned? And is there something specific that I can ask them to look for?

Answer
Ok here is what you need to do.

Get the new tires for a fresh start.

Then get an alignment, and try a new shop.

Make sure the shop puts the correct PSI in all tires.  Check your driver side door for sticker.

Make sure the shop does a dynamic balance and NOT a static balance.

Make sure you always have a tire rotation done every 7500 miles or every two oil changes ( 6000 miles ).  When doing this have the PSI check.

Make sure the correct torque is applied to the lug nuts, not just an air gun.

Also, do not use stick on weights.

Follow the above should make your tires last longer.  

Also, buy brand name tires.  You get what you buy in tires.  Cheap tires are junk.

I recommend the following brands.
Michelin
Uniroyal
BFGoodrich

Ok, it sounds like the front driver is a alignment problem and the driver rear sounds like a incorrect PSI problem.

alignment do not last.  Every time you hit a bump or pot hole, you knock out the alignment.

Good luck,
