If the rear tire blows brake with the front brake only. if the front tire blows brake with the front tire. if you brake with the tire blown the wheel is going to come off the rim and everything going to be a huge mess. While breaking head for the grass or off the road because you're going to have a hard time keeping the bike up and may have a high side or low side fall depending on your speed. your tire is only going to blow if its not maintained properly. So remember to always check your tires before and after riding for any defects. that few seconds could mean a world of difference.
I've had 3 blow out on me {years back} 2 back one front. You need to let of the throttle and try not to panic. Remain in as much controll as possible while still trying not to get too tightened up. Once your speed slows to where you can use the brake use it LIGHTLY. If your in the situation where you have no room but need to stop then use the brake but once again easy as possible. I think the worst one I had was the back while going around a pretty sharp corner, but still managed not to crash.
the only reliable reason at the back of nitrogen is to quit oxidation in the tires and steel wheels. My cages tires' are packed with nitrogen -- with the aid of fact they are going to used for 6-10 years. My motorcycles won't. Nitrogen will make any difference on dealing with or tire life.
C. It has to be magnetic material like Iron or a rare earth like Neobyium.
