A person can get some farely good quality tires and tubes I'm sure...

Let us know what kind of tires and thicker tubes you find,,, even then its still kind of a crap shoot...

If @ilikeslowbikes switches to disc brakes he wont blow another tire the same way
What happened is. When stopping from M/B speeds the rim brake pads heats up the rim and that heats up the air in the tire increasing the PSI and the tube blows. For this reason many switch to disc brakes

On my exercise bicycle I have had the same problem here in warm weather Florida . I pumped to spec, got on the (cold bike) and when the tire heated up from just under a mile on the bike path, I watched it begin to bulge and then it blew up. Air heated up, over inflated and bam! From the other posts I am reading here, this is not uncommon and can be prevented by staying below the max PSI. Hope you recover quickly.

What type brakes do you have? I have a similar bike..Schwinn Siesta. I put caliper brakes on my bike because it came with a coaster brake. These caliper brakes are not intended to be used on an engine driven bike rolling 35mph. They flex and distort the caliper frames trying to stop a fast roll. The pads can easily walk off the rim and touch the tires. I would imagine this creates a dangerous situation. These caliper brakes are not much better than the coaster brake. If you have cheap caliper brakes I'd be mindful of this. Another thing you mentioned..these walmart tires are not rated for 30-35 mph. I'm currently looking at fitting this bike with better brakes and tires. I have it capable of rolling faster than it can do safely and looking for more. It's always more. That's a big part of the problem.
Gotcha, yup I got new tires, and as for brakes, I replaced the stock front brake with a dual pivot Tektro brake and it honestly works really well compared to the useless stock one. I've still gotta do something about the rear though.

I hope you get to feeling better soon. Sorry I didn't open my prior post saying this. Also... I hope you didn't tear up your bike too bad.
No worries, I'm doing a lot better now, and the pull starter on the gx50 took most of the hit, so the bike is shockingly okay. Strong little engines :)

I'm not sure if it was the brake pads in my case because as soon as I tapped the front brake I was down in 0.5 seconds, so I doubt it was enough time to get the tire to heat up that much. I would much prefer discs but there doesn't seem to be any simple way to put them on :(

Sorry too hear you went down bad,,, I hope your ok and your bike came out of it ok...
Crappy deal for sure...

That or air down that was suggested earlier...

Im a Spungg Bob tire dude ,,, not too much air,,, and enough air in the tires too limit the chances of smashing a rim off a rock since I ride mostly off road...

Thanks for sharing,,, yes,,, a blow out at speed could put any of us down for sure,,, guess that's another reason I gear my bikes down...

40 ++ mpr seems pretty fast for me,,, same for 30 ish,,, I'm ok with my 8 too 12 mpr stuff with options of 22 too 25 max...

Just me is all...

I've been riding with limited riding gear,,, coat,,, helmet,,, gloves incase I have to bail,,, all of us know that the ground is mighty hard,,, and it happens fast,,, gravity plays a big role im sure...

Let us know what kind of tires and thicker tubes you find,,, even then its still kind of a crap shoot...

Will keep you guys updated when I fix the bike back up with better tubes and tires. Thanks for the advice!

Thankfully, a huge chunk of it broke off when I fell. Better that than my head
If your helmet is cracked, it has served its purpose. Time to get a new one. Stay safe. I honestly still think your brake pad came unadjusted and dug into your tire's sidewall. I like going slow too. I also had a catastrophe happen when I was a little boy (9yrs old) where my front brake fell off the bicycle when I was trying for a speed test down the road. I just remember peddling my heart out and the next thing I knew I was laying on my friend's couch and his parents were freaking out. I couldn't play little league for a week! I think because of that incident, brake safety I am probably too concerned about. I check my brake mounts constantly while riding to see if they've vibrated loose.

Yeah, when I hear of peoples tires blowing from rim brakes heating up the rim they usually were slowing down on a steep hill when their tube blew But they did have good quality tires. But in your case you say ya just taped the brakes At max 65psi It must of been a crappy tube or tire

BTW manufactures of bicycle inner tubes say to replace the tube every 2 years.
If ya see sidewall cracking or hardly any tread replace the tire.

Personally I replace tubes every 2 years. The front tire always last longer than 2 years but I replace that too about at 2-3 years. the back tire never lasts me more than 1,500 miles, which I do in one year
So I always have a new rear tire and o every year and a new front tire every 2-3 years
I put 45 psi in my beach cruiser Chin Sheng classic knobbie tires. I've never had a tire blow out tire failure in 16 years and 39,800 miles. My Whizzer M/B normal cruising speed is 45 mph too. I have F&R Worksman Cycles Drum Brakes

Good luck with your new tires.

Disc brakes can be a little tricky too install but usually can be put on a beach cruiser. Disc brake adapter kit's are sold for a beach cruiser style frame

When I first heard this my immediate suspect went to a brake tire rub. With rim brakes they some times loosen and move on you. Which is why one should check for this at least once a week. When I used rim brakes on the LandRider I'd bump brake going down steep hills to prevent gaining high speeds. This also ment I didn't have to brake hard because I was doing 50+ mph causing the rims to become hot enough to blow a tire.

Unfortunately for you there's a double whammy. A hot tire from hot rims and a roller heating it up as well. My best advice is lengthen your stopping distance and learn to bump brake. I'm 250 lbs, my bike weighs a 100 lbs and I live in the mountains; 30% grade hills are common here. So when I had rim brakes I'd start the slow down process a little early lengthening my stopping distance.

I now have front and rear disc brakes on the Sidewinder. Which greatly shorten my stopping distance. I still however bump brake coming down steep hills where I know a STOP sign or traffic light is at the bottom of the hill.
