Getting back to my original query, am I being led to believe that my wear problem might be resolved by increasing the tire pressures? That doesn't make sense to me at all, at all.
I check the tire pressures regularly (religiously) and have been using the same tire pressure gauge so maybe it is faulty and reading low. That would account for the actual pressures being higher than what it should be. I'll check that out next time I'm in my shop.
