I have a 2013 Hybrid with 83k on it. It is mostly highway miles. We are currently on our fourth set of tires. It seems that the rear tires are wearing out before the fronts. They seem to be wearing evenly across the treads.Once the factory tires wore out we replaced them with some Continentals which we paid a lot more than OE. They wore out so quick that Continental replaced them for free. They put four new tires on and they wore out just as quick. Instead of spending more money on the same tires, we decided to have the dealer install OE tires. They are again showing significant signs of wear just on the rear tires again. The dealer says the shock are worn and need to be replaced at a cost of $395.00. I do NOT agree with this as they seem fine and show no visible signs of wear.
I also notice that the cars rear 'Wiggles' when going over bumps in a straight line, especially at highway speeds, in a side to side movement. Sometimes it wiggles so bad it will cause my head to wiggle similar to a bobble head. I am sure that this is related or causing the rear tires to wear quickly.
Any advice on where to look or what to check?
