30x9.50x15 fits very nicely in the TF trucks. However, a 6.5" rim is a bit on the narrow side for the wide of a tire. rule of thumb is that the rim width be approximatly 2" narrower than the tire section width. This is for proper sidewall support. So in the case of a 9.50 tire, a 7"-8" rim would be best (I'm running an 8" Rallye). Too narrow of a rim will cause handling problems, especially wander. This is aggrivated with shorter weelbases. In the case fo the OE rim, which is a 5 1/2", the 7.00-15 would be ideal.
