You must be one of the younger ones who think they know everything! Northern Virginia eh?
Your reference to my location is supposed to do what? Scare me? Your reference to an assumption on my age is erroneous and idiotic. Referencing another guy's employment above is also stupid. I can't tell if you're trying to intimidate with your keyboard warrior skills.
Your position on this matter is also idiotic. If you track your car, then matching tires is more important, as you're pushing the tires to their designed limits. But, at the click us track guys go through tires, even that is not always possible; its a give and take . . . cost versus performance. Everything is a trade off.
On the street, the idea that you "must" have matching brand tires is lame and mostly propagated by folks trying to sell tires. It's like trying to say that your rear brake pads have to be changed out when your front pads expire.
Do my tires match in brand and model on my daily driver? Yes, but I wouldn't pay through the nose to make that happen. Matching tire size and tw rating is going to be more important.
Go ahead with another stupid response. Each one gets more goofy.
