We no longer carry this tire in a 16" due to it's width, it does not fit the Surron without some major tweaks such as removing the kickstand and setting the tire crooked in the swingarm to clear the chain. If you like the Intermediate to Soft Terrain performance aspects of the Dunlop MX33 we suggest looking at these tires instead which fit the Surron much better:
Mitas Terra Force-MX SUPER LIGHT 16" (Light Weight)
Bridgestone M204 Soft/Intermediate 16" (Light Weight)
Bridgestone X20 Soft Terrain 16" (Competition Soft Terrain tire)
Tusk T-35 Soft-Intermediate 16" (Best Bang for the buck)
