I noticed that you have Bridgestone tires and about 10K miles on your TCH. I've just passed 4K miles and have been running 42psi front/ 40psi rear on my Bridgestone tires. I don't see any evidence of excessive center wear so far. I'm amazed at how cool the tires are when I park at home or work.

When I first got my TCH, I measured the tread depth. New was 9/32 on the outer grooves, and 10/32 on the inner grooves. At 4K miles, I'm seeing just shy of 1/32 wear, pretty even across all 4 tires. It is a bit early to extrapolate, but it appears the Bridgestones will only last about 35K miles.

If WVGasGuy measures his tread depth, it would give a better indication on the life expectancy of these tires.
