Track side truer or the bigger AC powered one?

Trackside truer: get extra o-rings

AC powered one: make sure the threaded rod is true to the arbor its mounted in, it will effect how true your tires get.

as for tire size, it depends on what you want, your track layout, what type of car you are using, and what motor your running and what pinions you have available.

If your on a budget, you could start at 61mm, however, in racing, more mass means slower accelleration. Many people are starting at 59mm or less. Look around here for roll out numbers based on your motor, then go to one of the gearing websites to figure out what ratio it is based on your choices. (hint, 64 pitch gears are more efficent at transferring power than 48, I would upgrade when funds allow)...
