I run 4.30's with a 29" Hoosier QTP tire and I love it. I drive the freeway at 60 mph and turn about 3200 rpm. It dont bother me at all and yes I dont have to go any faster then 60 as I just run the slow lane when I need to. I have driven 120 miles one day all on the freeway to a show. But the 4.30's more then make up for it at low speeds and at the track. I love a hard launch and good low end. I will put up with 3200 rpm on the freeway to have my 4.30's as I did it all the time back in the 70's. Ron
