Hi I have a 2006 s281s/c and i've made some improvements,but i need traction, the car weights about 3,900 pounds(w/driver(me=255)) and i bought a set of bullit wheels and Bfgoodrich DR's (275/40/17) from the tire rack, but i still have no traction . with the tires at 14psi the car doesn't make good 60ft times and is spinning them in 1st,2nd and the beginning of 3rd. now the ?'s
1 Do i need bigger tires(18) or smaller(15)?
2. Will a 15 inch wheel fit my car?
3.Which tire do you recommend?.

Ahh My car is pushing about 450rwhp and has a 3.73 diff.
Thanks.
