Looking for wider rear tires for my sons Kazuma 50. The tires seem to 'dig in' in the snow and thought that a wider flat profile tire may stay on top better.

 

Onabudget,I have been looking for the same thing and what I have found out is theres not alot to do about getting larger tires installed because of the lack of clearance between tire and exhaust pipe.Somebody on another thread was suggesting spacers on the back to extend rim out first then getting larger tires,but the tire choices are limited in that size tire

 

I have also been searching for some wider tires for my daughter's 50. I bought spacers from speedtrapmotorsports.com and they really add stability and plenty of room for wider treads.
