OK gang, got a question on the rear tires on the AW Top Fuel dragsters. Has anyone tested to see if the size makes a big difference in how fast they are? I'm asking that since I wanna make this thing fast. Running poly mags, magnatraction rear gear conversion, 5.8 balanced and trued arm,shunts and braids, all in an original Aurora "Generation 2" chassis. Are the larger, .6 somehing diameter tires fast, or should I go to something closer to what the other 4 gear chassis run (in the .510-.525 range)? I have heard that the bigger diameter tires are slower than the others, especially out of the gate, but I was just curious if anyone has really tested this much yet? I do have urethane slip on replacements for the larger diameter, and I have several slip-on options as well as 'homemade' silifoams for the smaller ones.
