I GOT A 400ex and the back tires are getting there, and i was wondering if i should also get some different rims( size that is) would this help i have heard somethings about unsprung weight holding horsepower, would i be better off with more rim and less tire, also mostly trail riding what are some good tires for this, also versatile too. thanks

 

I have some .190 Itp wheels. They weigh about the same as the stock wheels but the stock wheels are more durable.

 

the stock rims are stronger and have the lip on the edge. get bigger tires for trail riding for more groung clearance.
