I am getting a little rounding on the front tires at 5000 miles. I have been running them around 38 according to the TPMS system which I question as to its accuracy as I bought a nice tire gauge from Summit racing and the TPMS is like 5 pounds different. So right now I am trying to figure things out. I want to try and run them to see what sort of maximum mileage I can get out of them. Vans seem to chew up front tires quick. Maybe SUV's and pickups do to I don't know. But I am getting a bit of rounding and have been told a lot of conflicting stuff from costco tire guys. I think I will not listen to them any more.
No prob man, that's why we're here, to help out. What's the prob?, just some rounding of the tires, or does it include cupping, wearing on the inside or outside?, a little more info will help. Another thing is at Costco they use an impact gun to remove & reinstall the lug nuts, a BIG NO NO; it's ok for removing, but for reinstalling, that should only be done with a torque wrench!! The proper procedure for reinstalling is to tighten finger tight and then use the torque wrench for the tightening of the lug nuts; in a 3 step procedure, never fully; EX. torque @ 90 ft. lbs., do 3 even increments 30, then 60 and finally 90 ft. lbs. Even when using an impact, they can use torque sticks, but IT'S BEST TO USE A TORQUE WRENCH, so you are assured no rounding, galling, seizing, or stripping of the bolts. Another thing is that you have an AWD which equals more weight & strain on the front end components; so basically you want to make sure your alignment is in specs, your tires are set at the correct psi (check it often), rotate and balance them often, other than that, it should be all good because you've got a brand new ride!. Do you go off road, since it's an AWD some people venture off road, especially in desert areas like nevada. BTW, I had a family member experience a similar prob, the tires were worn within a 2 year period and required replacement; took it to Costco showed them my records for align, balance & air pressure adjustments (done at a dealer - not Costco); they didn't honor it because they stated that the tires were supposed to be serviced at Costco and be on their computer; therefore it was customer negligence...oh well, I wont ever buy tires there!!. Need any more info, just hit us up!. Late.
BTW: were the tires bought at Costco?, I doubt it right; they came as OEM equipment is my guess...Late.
