Excessive Road Noise/Original Tires?
My wife's 06 Outback has ~57,000 miles and we still have the original tires that came with the car.
I noticed that when we take the car onto the highway there seems to be a lot of what I would call "road noise". (It is a pretty loud humming/droning when you get over 50 mph and seems to even out a little at about 70 mph - but no steering wheel vibration or pulling.) Is it time for new tires? I rotated the tires every 10k (+/-) and they were okay at ~51.5k (i.e., "a little cupping by tread looks good. The road noise maybe because the tires are probably getting harder as they are getting older").
So my questions are:
- How many miles did you get out of the original tires? (I'm over 65k on the original tires on my Honda Accord.)
- Is 10k for tire rotation too long for an Outback? (Bridgestone manual recommends every 5k, Subaru manual recommends every 7.5k)
- If the tires were not rotated correctly, could that have caused the premature tire issue/road noise issue? According to the Subaru manual, the tires should be rotated on the same side (not crossed). The only places that have done the tire rotation on the car were: the dealership, a local mechanic that I trust and a local tire guy that I trust...except for one time...I went to a tire chain for it. As soon as left the parking lot and drove down the street (maybe 3 blocks at the most), I felt like something wasn't right so I went back and asked him how they rotated the tires and he told me he crossed them so I showed him the manual and he flipped the tires that were crossed. Do you think driving a half mile on incorrectly rotated tires could have caused damage to the tires that lead to the road noise?
