Query: Great Bike, and tire can be replaced.

I bought this bike four years ago from Walmart for my one year old boy. He likes and enjoys it. Last Christmas I pulled it out from garage for my daugher, she's two years old, , the bike still works great. The only problem I got, was the tire, In a very cold day I inflated the tire, but in the next warm day my mother put it under the sunshine whole the day. then the tire was broken. I bought the BMX Bell 12.5-Inch tire from amazon.com, very easy to replace and now it works great. Will strong recommend to friends.Bell BMX Bike Tire
