 Hey guys, I'm Amanda here with George and today we're going to answer a question off Twitter from at jubicelizama. He writes, what is the maximum tire pressure I should use? It's a good question. George? Well, it depends on the type and the size of the tire. If you check on the side of the tire wall, it usually tells you the minimum and the maximum PSI. If you're riding a mountain bike or if you're riding a commuter bike, sometimes they have bigger tires and they take less PSI. When you're on a racing bike or a track bike, they tend to be higher, like 100 to 120 PSI. If you're riding under PSI, then you're usually going to be sluggish and it's going to take you longer to get where you want to go. If your PSI is too high, then it can cause a big explosion and actually be quite loud and scare you. So, how much air can I add to the tire before it explodes? I don't know. Let's find out. I smell a contest. All right, we've got two guest riders in the shop today, Anthony and Andy. All right guys, you each have a 700 by 28 tube and whoever can bust their tube first by using the floor pump is going to get a year supply of tubes from Pure Fix Cycles. Are you guys ready? Yes. All right. Go. Let's go, Anthony. Bust that tube. Come on, you got it. Yes. You got it. You messed up. You got it. Don't worry about it. You're good. You're good. Keep going. Yeah. Bust that tube. Yeah. I'm getting back. Oh, no. The tube is getting huge. You got it. You got it. Come on, Anthony. Come on. You got it. You got it. You got it. You got it. You got it. These are really strong tubes. Yeah, you got it. It's a little bit. Oh! It took over 150 psi to bust the tube. Obviously, you should never inflate it that much. And now, you don't ever have to worry about buying tubes for the next year. Lucky Andy. All right guys, that's all the time we have left for this week. Check out more videos online at PureFixTV.com.
