I got a nail in my stock rear tire and i'm having trouble finding the exact same tire to replace it. I keep finding the Bt-012ss instead of the bt-012. Can i use that with the stock front tire or will the bike handle bad. Of course the dealer wants to sell me a whole set. If anyone knows where i can get a stock tire from or if the ss will work let me know. My bikes been sitting for 4 days and it driving me crazy
