Subarus are very finicky with tread depth/wear. Subaru recommends that all tires should be replaced, not just one or even a pair. I write damage for an insurance company and believe me when I say I have replaced full sets to correct this issue many times when one tire and wheel was damaged. Could also be worn steering or suspension, rim bend, wheel weight knocked off or even bearing assy. I know some of those have already been mentioned.
Thanks! Ill certainly rotate some of the sneakers, with about a month to go until we switch back the summer tires and rims. Hopefully i pinpoint something this weekend.
All AWD vehicles need to have matching tires. Did the alignment shop give you print out of the specs before and after? Did they check the front steering and suspension components before doing the alignment?
The tires do match as far a brand, etc. I did get a before and after printout, but i am unsure how much deeper they went outside of just an alignment as i mentioned earlier. There little disclaimer states that they don't go outside the immediate tire or alignment job started on the bill after work was complete. How convenient right?
^^ this plus same tread depth of each tire.. Subie are great car but AWD has its disadvantages too...
Can you post a pic of the print out? They should have checked the front end before aligning it. There is no need in doing in alignment if it has a loose tierod etc. They should have also road tested it afterwards and noticed it was pulling.
Local tyre place here offers to fill tyres with nitrogen; claims give better ride but I have my doubts.
Theoretically better but practically useless in a passenger car application. Nitrogen fill is commonly used in racing and other applications where even the most minute details are controlled and the supply of N2 is convenient. If you need to top off a tire, do you carry around a cylinder of N2 just in case? I don't object if a shop wants to use N2 to fill the tires but I won't pay extra for it.
It's about 20% better than plain old air. It's interesting to think about as steel rims should not rust. There would be no moisture in it to corrode aluminum rims either. It is more stable than air as far as thermal expansion goes, and that is why it is used so often for racing or aircraft tires. But in everyday Joe's car? It's not like every gas station has a sign up that says "Free Nitrogen!" And the first time you top off with air, you pretty much nullify the benefits of doing an N2 fill in the first place. That is assuming your tires were completely purged in the first place, which is a whole 'nuther debate!
