I tried the M/T radials in 15x33 when they first cam out, 3000 lb car, going 8.70s. Radial :wobble: was terrible, pressure had to be about 14 psi minimum but very little higher or no traction. Fastest passes the car ever made though, for the fuel and conditions. 60 fts were in the 1.27 range on the best day, biased slicks would go 1.24 but loose ET down track.
