Well made about a 227 mile road trip yesterday, so far longest amount if time driving the car and pretty much a non stop trip up and back so it was a decent hard run for the old girl, 55mph 2 lane roads and alot of interstate at 70 MPH and I just filled up and got 21 MPG My jaw hit the floor, and that was with the air cleaner lid in the stock closed orientation. Cruise worked perfect the whole trip and the car had no problems pulling any hills in 4th gear without oven dropping out of lockup. Have to say i am quite impressed, Handled perfect, road good, these tire do have a fair bit or noise and i might try boosting the pressure up a bit I started off at 32 and have slowly worked my way up to 35 , I guess now I will just go right to 40 psi and see how they do.
