With over 1000 miles on the clock Dad thought it was time to check his ratbitetire insert... the ratbites have saved at least 7 punctures which could of been 7 new tires needed not bad for £18.
The handling at low pressures is great! And if you do hit anything big and sharp enough to puncture your tyre, you probably won’t have to get the mole grips out to straighten your destroyed rim bead.
Punctured not long after the glacier, I think it sealed but lost a lot of air. The RATBITE insert didnt survive but got me through at least 80% of my Megavalanche run - many thanks.
