I would expect that this particular increase would have a minimal impact at the end user level. The OEM's have options for Bridgestone but I don't believe any of them use Bridgestone as their "preferred" tire supplier. This increase may replacement tire purchases some.
Obviously, emission regs have had the biggest equipment cost impact this year. Besides that commodity prices such as glass, copper, and steel have actually stayed pretty steady so they are not creating new equipment price increases.
If you are in the "tire world", you would know that there have been several increases in prices on tires. We usually had small price increases every three months or so. A lot of fossil fuels are used in making tires, and that was a big reason for the price increases when the price of oil rose. I have had pretty good luck with firestone/bridgestone, but I do not like the bridgestone R250. They are part of the state purchase program. Four out of five times, I take them off of a truck, they are unevenly worn and/or out of round. I've seen this too many times for coincidence or to blame it on the trucks mechanical condition.
