Purchased a set of these for my M03. They do come with an insert but are very soft so I added standard foam tamiya 55D inserts also. I tested these on our synthetic grass track and was suprised by the level of grip produced. Similar to the Tamiya S Grips, however, one real big issue - they wear extremely fast!! Within two 5 minute rounds my humble M03 had churned these little bad boys into slicks offering very little grip by the end of the second race or 10 minutes of run time. Real shame.........

These are surprising good backyard tyres. If you're just driving with your friends in a carpark or your backyard, you'll be surprised how much grip these plastic looking tyres actually provides. Yes, the thread are thin, and they are not the best looking tyres out there, and they are quite hard to stick onto a rim, however, on performance / cost basis, I think they provide a good value for money.

Excellent tires! Great price! These tires have excellent grip characteristics and are easy to set your car up with. The stiff sidewall and square profile seem to make the mini handle more easily by locking down the rear end. A little CA glue on the edges of the front tires and you are good to go. These babies will make your car fly.
