Ordered four ExtremeContact Sport 275/40/20 106Y tires at Engine Dynamics of Newhall, CA on Monday and came in next morning. Price was better than any found online or locally. Tirerack still has back-orders. Having some other work done so won't be installed until Thursday most likely. Factory Pirelli All-Seasons only lasted 19000 miles. No way was I going that route again with the performance and price. As summer tires I expect a big step up in performance. While I don't expect much more in mileage, I am optimistic they will last longer than the Pirelli A/S. Let Brian know that J from the Hellcat forum referred you.
