Wow Jerry, those M/T's are a little over 24", but the BFG's are only 22". I actully did the 22" deal many years ago with a B60/13 Concorde Trac action belted and a 2.73 gear. But that was on a 15 sec. car. I'm a tightwade, so imo, it's probably not worth the money even though they would help some. Out of the two the M/T's would be best. I'd keep looking and hope to find a set of wheels that fit and a little taller/wider tire. That's if your willing to switch for just when you go to the track.
I think the 24.2" M/T streets would be the best bet if you want to drive them to the track, light years ahead of the tires your running now. May have a little spin off the line, but not down the track enough to make you loose at mid track. They would give a huge pickup in et imo. If you want to race alot and get the best possible times then the larger tire or slick would be best. If it was me and only raced on occasion i would go with the Streets and just work with the pressures to get the best times. I actully think with them and shifting in the 6k ish range you'll see twelves and that ain't half bad.So you're saying with either of these tires I will still be spinning up the track ? Even if I buy new wheels the biggest I can fit is about 245-60x15 , would this wheel with drag slicks give me the traction I need ?
