Guys I bought a set of the HPI Phaltlines mounted on Blast Chrome Wheels. I have some flat spots in the factory wheels and the truck was hopping all over so I went to Sears this morning and purchased a thin wall socket and did the swap. All I can say is what a difference. The Phaltlines dont grab as much as the stock tires, but they drive and handle so much better on pavement. The truck doesnt want to flip over as easily while in a high speed maneuver. It turns on a dime, and accelerates like a bandit. I wish Traxxas would consider making a set of street tires for the Maxx's. The Phaltlines are in my opinion a 9 out of 10
