You've got two tyre diameters on standard Tamiya Mini sized wheels 55D and 60D (in mm).

HPI do some "inch-up" style rims for the Cup Racer (they call them MX60) and I think Ride do some inch-ups wheels and tyres as well. These aren't compatible with the standard Tamiya wheels.

The larger wheels have a larger rollout which means that they are faster on the straights in fixed-gearing classes. But there are handling effects as well, which I personally have no experience of working with.

Locally we use the Sweep pre-mounts everywhere, indoors and out. Always 25s on the rear and usually 33s on the front. They are a 55D tyre, but local rules mean that 60D tyres don't get a straight-line speed advantage.

There are lots and lots of other tyres out there though.

PS be wary of bertrandsv87's advice. He has mostly strange ideas (along with a handful of good ones) and it is hard to tell whether he is a troll or a lunatic. Personally speaking I wouldn't touch the gears with anything.
