I got really frustrated with leaky tubes. I should not have to pump up the tires every day. The quality Goodyear tubes of my childhood are now just more inadequate Chinese garbage in a Goodyear box. I mail ordered the top Michelin tubes at almost $20 each. That was about 8 years ago. They still work, they do hold air and my tire pump and I really don't see each other much.Had one of my NEW Walmart tires and tube just swell up about 5 miles from home the other day and then rub the brake pad until it blew out before I could get home. So I'm waiting on two new OEM tires and tubes I ordered off the internet. Almost the exact same price as that Walmart crap.
