I know when we talk launch we look at tire dia as being part of the gear reduction equation. But what if we're not talking an actual launch. We're just talking that initial couple of feet at light throttle. My car does that very very well now. The strokers cam and carb were all set up for that intial snap in your neck. My 15 inch cragars I just bought to replace my 14's (cause selection of 14" rear rubber is a joke) are only 8" wide in rear. The 14 in BF's that I run now are a hair under 26". I'd like to go taller and wider or atleast one of those to fill the wheel well some. Looking at the M.T. sportsman radials they have a 26.1" dia that was measured on an 8"rim only gives an 8.8" wide footprint.If I go to their 10.6" it says it fits 8-10" rim but I'm told that because I'm at the very bottom of that it may crown a bit. I'm told that if I have to be at the minimum thickness of rim I'm better to step up to the 28" cause it would crown less because of having for sidewall to straighten back out. I can see the theory behind that I just wonder how much that inch on the radius will kill me at initial throttle response?Hope I didnt confuse everybody to bad
