I have the pleasure of driving these tires to work each summer weekday (dry & warm asphalt) up one of the twistiest roads in the west (30 miles of 30-50 MPH back-to-back hairpins, no traffic). Weekends allow more spirited speeds on various trans-Sierra highways.
In all endeavors, these 08s are effortless, noiseless, and predictable past cornering traction limits (slow & easy break, gentile recovery). Truely point & shoot!
The 08s took 800 miles to break-in (felt greasy at first), and rears only last my driving style 5,000 miles till bald (fronts last three rears). Wear is even across the tread, with no cupping. Tires balance inside/outside with minimum weights.
Of all the X-Treme Perf brands I have purchased from Tire Rack, these 08s allow my go-cart to perform better than Honda or Newton ever imagined ;)
