You are buying one or a set of tyres depending on your choice, as pictured.

We don't suggest solid tyres because of the vibration that could loose the bolts or damage your scooter and the solution to punctures is simpler. Say hello to our new range of self healing tyres with a bed of gel in the inner part of the tyre. We can't promise miracles but we know that they will drastically reduce punctures.
 
This 90/65-6.5 CST self healing road tyre will fit scooters including:
# Buddy
# Buddy+
# Zero 11X
# Wolf Warrior
# VSETT 11+
#Quickwheel Explorer
#Boyueda and many more electric scooters.
There are no instructions with them so if you don't have the knowledge on how to fit them, we strongly suggest that you seek professional help.
