I have an old kids bike. It has been in our family for at least 30+ years. However it was left in the rain by the our resisdent bike killer. Its a bloody mess so unless am told otherwise i think its best to buy a new rear wheel
But am unsure the difference between the two sizes. http://www.tredz.co.uk/.Kenda-Kids-12-inch-Tyres_40597.htm
