Not sure how they drive, but they STINK. Literally. I've driven M-Chassis, 1/10 TC, 1/8 buggy, Monster truck and handled tonnes of tires. They smell so bad out of the package that I can't keep them in my house or my car. They're airing out on the driveway overnight. I washed them with soap and brake cleaner. Helps a little, but can't get the smell off my hands.
If the smell doesn't improve, I will have to throw them out without ever mounting them.
Got a set of these to try for our Cup Racer class. We race a low grip carpet-type of surface and tires are extremely important. These are a bit smaller than HPI Cup Racer tires, but normal for M-chassis cars. The grip is fantastic and they even squeal a little if you really push them in the corners. So far I have about 1 hour runtime on them and they are holding up great. You will need a set of foam inserts to use these with best results, I am using Sweep Racing soft inserts.
Tried this set of tires and rim on my M03 on carpet and surprisingly these tires had a lot of grip! Strong wheels with grippy tires makes this package a really good value! Note that these tires are not pre-glued onto the rim. So you will need your own inserts and glue.
