Out cruising today , thought I would see how the traction is. Launched at about 3000 RPM , Little to no tire spin, heard a "klunck" i never heard before,( hoping that was the pinion snubber) and a bog I have never had with the old low traction tires. I didn't try it again, but looks like the Holley is going to need some tuning. No tire spin on a second gear 4500 RPM shift. I am impressed with these tires..........................MO
