I fit 10.5 x 30 Radials on our Demons.
The radial are quite a bit narrow than a bias.
We do have offset hangers on the bracket cars.
The radials with Cal Trac work fine for us even with a
4 spd or transbrake. Our suspension is very well tuned though.
Mickey Thompson (Now owned by Goodyear (Our Sponsor) make
a great bracket radial that lasts forever.
The radials do not recover as fast if they spin = But by then you have
probably lost the race if you spin!
Our 71 Duster 340 with Thermoquad/Stock Compression/Stock Head cc
on ports run High 9's @ 130 with 10.5/30 Goodyear Radials in good air when
we need it to.
