Mine was on the street on a back country road, if you're getting tons of tire spin your tires are probably your problem.
#1 Too hard of rear rubber composition, the higher the UTQG Treadwear # the harder the rubber, 500s spin like butter, 300s are little better but still spin, 200s are even better but still spin as well, the lower the number the softer the rubber which gets better off the line traction, but the shorter time they last you. Best rear tires I have run yet are the Mickey Thompson ET Street S/S tires, you can buy an entire set of cheap tires for what 2 will cost you, an R2 rubber composition Treadwear # is 000.
#2 Bad rear negative camber causing the tire to not lay flat to the road, usually physically evident by extreme tire wear on the inside of the tire. Many go to wider tires thinking that will solve their problem and end up with worse times than the 245s. That is because the wider tire with bad rear negative camber, is only touching the road with approximately 50% of the tires footprint under hard torque acceleration. Where the 245 was at 100% footprint to the road the wider tire is now supplying less traction because it is not fully contacting the road.
#3 Running an Open differential.
Almost forgot #4 Matching the rim width to the tires suggested to run on them, if the tires require a 10" rim and you are cramming them on an 8" rim, it bows out the tread footprint. So properly match the tires to the rims.
I have been saying this all along but very few actually listen, many want the git and go, but are not willing to accept lower mileage from their tires. So it boils down to if you want high mileage from your tires, UTQG 400 and up, you are going to get pitiful off the line traction does no matter the brand. If you want excellent off the line traction, UTQG 100 or lower, but you'll only get about 10,000 miles from them, and they are expensive tires.
