Get the dang tire and ride it to ES. befor you get there you will wonder why you thought twice I've run from 32 to 40 psi and dont see a big difference, got 14,000 on my goodyear F1 and it's good for another 20,000 at least. I don't get concerned about high speeds on hot days, I don't hold my breath every time I hit a stone in the road. I pull a trailer and can hardly tell it's there. The carcus of the Metz I took off was about the thickness of a shingle, aaat 3600 miles. How many people here have had a stone poke holes in there tires. And they talk about safety. I have had three blow outs at hiway speed and that will stain your skivies. If I could find a darkside front I have that too. It not only an econimics issue for me it boils dowm to just how frickin stupid do tire manufactures think I am.
