why are they faster,and what make have you had the best results with . Our current tire is M/T 9.0-29.5-15 bias. Who makes the best radials.

Hans, as you probably guessed, we have tried them all! On my car the Goodyears have been consistantly quicker. The M/T "new" 2001 radial tire was a close second and the Hoosier was right behind it.
On TOny's Capri the Hoosier was worth a solid tenth over bias ply tires. We are stuck with the Hoosier as they make the shortest (92.5 circumferance) 9.0 x 30 radial. The others are all 93+ and won't fit as well and hurt the top end performance.
The down side is the Goodyears wear out in a hurry. About 30 runs max and they are history. Hoosiers last about 90 passes and are available in two circumferances as are the Goodyears. The M/T's we have been testing seem to last 60 or so runs. They are only available in one circumferance (93 inches).
The reason they are quicker and faster is that they have a stiffer side wall and they do not wrinkle up or roll under when you hit the tire at launch. Their contact tread compund is very soft and has incredible hook. Also Hans, they keep their shape going down track and DO NOT grow on the top end keeping your RPM up.
If you measure the circumferance of your current M/T tires and tell me what RPM you are going through the traps at now I can make a somewhat educated recomendation for you.

Thanks Alex, great info about the tires . The circumference is 92.5 and the rpm is 7200@110mph. The hp begin to drop of at 6900rpm,so possibly we do not need more finish line rpm .

Hans, on your heavy *** car the M/T radial would be perfect! It is 93 inches exactly and would reduce your top end RPM about 1 to 200. You can order them direct via an 800 #. It is 1-800-222-9092 ext. 114. Ask for Frank Papp and tell him that I referred you please. Alex

Also, make certain that you run them tubeless and start out with at least 20 lbs of pressure.
