The rear tyre of YAMAHA FZ-S and FAZER have wide tubeless tyres. Rear tyre looks good but many problems faced by the FZs and FAZER bike riders. The main Problem is that many nails, screws, sharp metal object etc gets prick on the wide tyres. Hence the air comes out from the tyre most often. It doesn't work if you put patch on it because patch comes out slowly. One cannot afford to buy a new tyre which cost around Rs. 3000 without using it for 25000 K.M.
The best solution and best way to get rid out of this problem is to put a Tube inside the tubeless tyre. A tyre having tube will not get leak easily. A tube cost around Rs 300. It is better to spend Rs. 300 on a tube instead of Rs. 3000 for a new tyre.
