My car ain't no rocket, so I'll tell you that it's ran a 1.48 on the 295/65R15 MT radials but only a 1.54 on the 29/10.0 Hoosiers. Both dead hooked but were on different race tracks so it might not be a fair comparison. But I can tell you that I've never "FELT" the car hook hard with bias tires...with the radials you FEEL it and you know it's gonna be a good run.
