Tru Blue Goo, tyre seal, 250ml. Seals leaks as they occur and balances the tyre. Seals up to ymm in tubes and yymm in tubeless tyres, Australian brand, developed in Australia, Does not affect tyres or rims. Ideal for any tyre. Road motorcycles use 300-500ml in rear tyre; 250ml in front tyre. On normal width tyres on older motorcycles I have succesfully used 250m per tyre.
