I need some new tires for my Blaster and was wondering which size is better 18" or 20" for riding in the desert and climbing hills, sometimes riding on an mx track.Will it affect my riding,jumping,top speed,etc. Thanx for any replies.

 

i would go with 20. 18 makes it sit so close to the ground, that when you are on the trails you get hung up everywhere and on hill climbs loose your momentum because of bottoming out on the skid plate.
