Thanks for that info.
I need new tires and have been running the inexpensive Firestone Indy 500s, which I thought was pushing it, but at least those are made by Bridgestone.
If I drove more daily-like I can see using something potentially questionable, but when mine's out it gets pushed to its limits (or mine, as I learned at Radford) on twisty roads. Plus there's generally a rock wall on one side and a drop on the other - in some places several hundred feet worth - so I'd rather not give up much grip to save a few bucks.
Also, I absolutely won't tolerate tires that aren't balanced to perfection. If it takes me an hour per tire to reach that goal, so be it. Starting with a quality tire usually makes that task quite a bit easier.
