jigga,

Those wheels are dialed and make the truck more agile. They do bring the top speed down a bit but in the dirt, tearing up hills and over jumps it should be a lot better. The truck will now have more torque (due to the changed rollout ratio and the incredible loss of 4 pounds). Once that 25 tooth pinion comes out you'll have most of your top speed back. Have fun with those new tires. You should have a nimble Genesis on your hands now.
