OEM tires on my car. They will probably last 40,000 miles, but I want to upgrade wheels/tires before my next trip to Tail of the Dragon. The o.e.m.'s have done two Dragon runs and two HSAX track days. Have been shopping Tire Rack for a grippier 4-season tire based on UTCQ rating (300). Can't find one. This confirms my subjective experience: the best 4-season sporting tire I've driven. They stick and stick with excellent feedback about the slip angle.
I will re-up for these o.e.m. tires mounted on OZ 15-lb. rims from Tire Rack in September. The negative reviews astonish me. I can back through 4 of new snow in my driveway. Winter traction is average for a 4-season performance tire, a small price to pay for summer fun.
No hydroplaning problems. In fact, they track better through deep water than other high-performance tires I've owned. Superb on rainy Interstates at high speeds. Can spin 'em from a dead stop at a greasy intersection. Would be disappointed if a Civic Si couldn't!
Noise and ride harshness not a problem; no worse than other high-performance 4-season radials I've owned. But the grip is better. Seems to me that if these factors are more important to a user than dry/wet summer grip, should not be on these tires in the first place.
