Tyre Inserts

[alan p]

I need to replace my inserts due to sand in the tyres, I use Schumacher medium inserts at the moment, is there an insert which will resist the sand better?

I always found that Schumacher inserts crumble away over a fairly short time, don't think it's just down to sand getting in.

Try MrO's inserts, they last for a good long while.
