It's the 7th time my back tire explodes. I have single wall rims and I run 20x2.45 tires in the back with a 20x2.40 in the front. I believe it keeps exploding because I run 20x2.40 tubes and that .05 difference is allowing my tire to slip off the rim and explode. Can y'all please help me?!!

Pics of rim side wall, rim strip, tire sidewalls and bead.

Tubes shouldnt be a problem.

Im going to guess your rimstrip isnt up to par. Or you have a spoke/sharp nipple poking through.

Definitely not that 0.05” difference, tube sizes don’t have to numerically match exactly. Like Bullet said, do a careful inspection of your parts.

Get a new rim. Have your local bike shop install a tire for you.

Everytime it explodes it's because the tube pushes the tire out the side and expands but eventually explodes

I have a Primo Stevie Churchill tire on the back and it's a Kevlar tire, I previously had a Stranger Ballast tire of the same size that blew up so hard a chunk of bead came off

Sounds to me like your bead is broken. If not, maybe your sidewall is damaged. Check your tire carefully.

As in the other thread I posted in. The rim might be too shallow to effectively hold the bead in place. FYI, working in a bike shop doesn’t automatically mean you know what you’re doing

Yeah, Ik thanks. I never had any problems with the stock tire which wasn't so bendy so I think from now on I'll just ride tires with a former bead
