@R.Shackleford, Great information...wrong delivery. I only asked b/c I'm new to inside racing on clay. I only get about 3 hours a week to work on 2 chassis including any rebuilds or prep work because I work 60 hours a week and have a wife, 2 kids and responsibilities outside of the hobby. To waste the time and money to mount a set of tires up wrong is just dumb without seeking a reasonable method the will produce the results I am looking for. Again, I understand tires and inserts as I have been in the hobby long enough to remember Kyosho reusable 3 piece rims with no foam insert and the first car I drove was a Rough Rider with a stick radio. I just haven't raced a 2wd buggy in a long time and things have changed drastically in the hobby since I bailed out in 2005. So before you start saying that I would have been screwed before the internet you should realize that I started in this hobby as a 6 year old kid before there was an internet.
