Ride-On TPS for your tyres. Now available in the UK. I've been using for years in the bikes and now in the cars too.

It is easy when finally changing tyres too, not messy like Slime and other tyre products. Plus any residue that may be left on the wheel can easily be rinsed off. Works on tubed tyres as well.
