Thank you for your reply.
Why don't you use Slime on the x2?
There are three Sealant categories:
-Tire Sealant
-Tube Sealant
-Tubeless Sealants
I'm looking now at their site to find out which is the right sealant type for a Segway. Do you know which product is more suitable for the i2?

I think tube sealants applies in our case, right?
Our tire size is in diameter 19 in (48.3 cm). I was looking for the dimensions of the i2 tires and then I bumped into this
link to find out sizes. Which are the i2 tire dimensions? There is a guide and also a
custom tire calculator in Slime's site to identify which product and quantity is right for each application.
