There’s a popular tire chain in this region called Les Schwab Tires. Their tires are not the cheapest though they’re known to have good service and free tire rotations for the life of the tires.
What I found out after awhile is why they offer free tire rotations. It’s so they can do all the other “free” inspections such as brakes and suspension parts to offer repairs to the customer. I’ve taken their information from my free rotations and done the repairs myself.
Well the last time I had a tire rotation done with them the tires were not rotated, even though it was taken in for a rotation, I waited 20+ minutes and had the keys given back to me (with a smile if I recall correctly and an enthusiastic ‘it looks great’). The reason I knew is because there was something distinctly different about one of the wheels.
I called them and they said that rotations are done based on the need of the tires condition, (ie: tread wear). This was before I knew about measuring tread depth myself. So I figured that made sense. Took it to another location after explaining the situation and they looked at the tires and said it didn’t need to be rotated.
Later on I get my own tread depth gauge and when it comes time or a tire rotation I measure it myself and see the front are worn down a little more. Next rotation, same thing.
I think that the rotation was not done because they simply didn’t want to do it, it’s an older vehicle and figured they weren’t going to get repair(s) out of me in the hundreds of dollars from an inspection of other parts.
If it wasn’t for that distinct difference on one wheel I would not have known. Had I not obtained a tread depth gauge I would not have known that the front always wears down faster than the back.
