RAZOR CRAZY CART TIRE

I purchased a pair of tyres and tubes for my kids carts. The tyres appear to be identical to the ones that come with the carts, but only lasted 3 and 4 rides before they wore through. My kids got 15-18 rides from the original tyres and were careful to try and make these last due to the $100 cost of 2 tyres and tubes, but they were very short lived.
A friend has suggested solid scooter tyres from trademe as a longer lasting alternative.

The staff very friendly and helpful nothing was a problem great service thanks
