Tires Tire tubes keep popping.

My apologies for any inconvenience my possible lack of comprehension may have caused you.
My intention was to contribute, not to be a "Snowflake" for you to have to deal with. I will try to be more thoughtful in the future.

PSI on the sidewall can reflect the tread pattern uses and not the strength of the tire

This info for the Cheng Shin 693 & 241 tires only

Here's an Example: beach cruiser tire vrs street tire
26" x 2.125" Cheng Shin 693 classic knobbie, psi on the sidewall says 30 - 35 psi
26" x 2.125" Cheng Shin 241 street tire, psi on sidewall says 45 - 65 psi

693 tread pattern is for sand gravel and pavement
241 tread pattern is for pavement only

693 and 241 are close cousins it's just the tread pattern that's different
The construction strength of the 693 and the 241 are exactly the same

The only reason the 693 recommends 30 - 35 psi on the sidewall is because the tire will perform better in sand and gravel @ 30 - 35 psi
45-65 psi can also be put in the 693 if your gonna ride on pavement only

I studied these tire because I was curious about their PSI differences
I use the 693 on my Whizzer M/B and inflate my tires to 45 -psi

241


NOTE*
CST 693 & 241 are bicycle tires and at M/B speeds it will increase the PSI in the tire,
I recommend not inflating these tires past 50 psi

Them 241 tires are a good tire to, I just prefer the knobbies where I ride.

I tried the 241 and it wore out too fast, the rubber isn't as thick as the 693

Besides the 693 is period correct for my Whzzer, The brick tread pattern is from the original duel sport (enduro) tire
GoodYear used to make that tire before it went to China in the 70s

Today there are many different brick tread pattern versions of the 693 made by many different manufactures and none are as good as the CST.
Except 1 it's the Bell Classic Knobbie made with kevlar, I've heard and read good reviews about that tire

OP, you stated the holes are always near the stem. Are the holes a slice or a pin prick? Is the hole on the surface, side or bottom of the tube?

all I know is I ride with my tires on a 26" MTB aired up to about 60psi and they never popped on me, and my bike hits 48mph.

I don't like running high pressure. It is just too stiff.

I have RockShok Judys in front and a seatpost shock as well, so I get by!

Ahh, my bike is a cranbrook, so I run 40psi. My new bike will have front suspension and a springer seat. Much more comfortable than a stiff chassis

I'm telling ya! I started out building Cranbrook Beach Cruisers but evolved after 40+ builds and now only build high-end mountain bikes like Giant, TREK, Specialized, and some Mongoose and Diamondback. I pick them up on FB marketplace, go through them and end up with fast, light, nimble, and comfortable riding machines. For under the price of a cheapo kit you can get one and you will thank yourself down the road. The bearings, tires, brakes, and gears last much longer, and pedaling them with the engine off is like it's not even on there. No longer white knuckling it through potholes and crummy roads is more than worth a few bucks and a little time. It IS all about power-to-weight ratio regardless of what some say. The lighter the bike, the faster you go, and Never, Never had a crack or frame issue on any of them.
