The biggest obstacle for the CT is how tight it fits on the rim. I do my own tire work with a manual no mar pro series tire changer and have changed 40-45 mt's and about 15 tires on various cars and trucks that I own. The Riken ct on the rocket was hands down the tightest fit. Part of that is due to the lack of center recess on the rocket rim, but even without that variable it is still very tight. I will hold out until I have installed a few more cts on my rocket before I can definitively indicate that was not just a fractionally smaller tire than normal, nonetheless, **** that was tight. Oh, and by the way I used a 245-55-16. If anyone has any tips or tricks for easing the mounting please advise.
