Hello, since I no longer wanted to trust the standard TireFit, I bought a spare wheel. Now I wanted to find out – just out of curiosity – how the TireFit behaves in the tire and whether the rim really sucks as terribly as described here often. Also here was recently pointed out that TireFit hardens to large lumps and then the tire becomes very unbalance, why then you can only drive Vmax 80 km/h. So I have the stuff in a bottle tipped and observed; consistency and appearance like white latex paint, but slightly smells of ammonia. But nothing happens, even with an open bottle and constant shaking. For 2 days the stuff is still as liquid as before in the original container. Does anyone have an explanation? The TireFit was delivered with the new car in 2016.
