These tires are great. I purchased these from my local hobby store as they were the last ones in stock and all I can say is wow. Tamiya really doesn't lie when they super grip radial tire. I installed these on my Tamiya TA02 and all i got was major traction roll. Every time i shoved my car into a corner it would stand on two wheels then flip. I'm amazed at the level of grip these give. I do want to give you a tip though; if you plan on using these tires in a medium speed grip race, make sure your rims can handle the cornering forces because standard Tamiya rims just didn't cut the mustard, especially when I hit a bump or a rock during a fast bend. They would just snap and I would take out someones 500 dollar car. Already took some stink for that. These tires are grippy because they are pretty soft and do wear out after a relatively short time. Don't expect them to last a long time if you're racing on asphalt, but on carpet they last longer, but don't quite grip as well as the M2 radials. In a short word, for asphalt, get a couple sets of these. For carpet, get the M2 Radials. This product gets my recommendation and I will be buying more of these soon.
