I use m/t's and i've used 11.5 and 14'' tires and I run them up to 8000 on the burnouts with a glide and run a 6.20 1/8 and they never smoke but they bring the front tires up 5 feet every time foot bracking in a 2500 # 85 camaro. I don't think the smoke is all that. like the man said as long as your hooking up thats whats counts. let eveyone else put on the smoke show.
