18 to 22 lbs. is the norm. as far as the pattern thats common for radials . thats why many run the 10" rims. try putting a shoe polish stripe accross the tread. then make a run and see how much is gone. somtimes it looks as if the sides are not making contact, but they will on the launch. good luck . and p.s. if you have double adj. rear shocks try running them looser on the ext. and firmer on the compression .
