Not sure about tyre weld - its not always a possible or practical solution
I was concerned about all three tyres on my M3 - particularily the rear - difficult to get to and if a full deflation thats it - snookered and a recovery ride home
After quite a bit of research I bought a product called Air-seal this stays in liquid solution within the tube/tyre.Its used on all kinds of cars/vehicles.
The litre bottle cost £25 and will treat all 3/4 tyres.
This may not be the perfect solution - and may have its detractors but it is an insurance and a comfort to know its in the tyres
