Please say, those are the original tires that came with the vehicle 30 years ago.

Why are bubbles in a tire so horrible? Are they bad because scraping against stuff can make a flat super easily, or do your tires just look bad and old with bubbles?

How do you safely deflate them? Driving over a spike strip?

Not quite that drastic, but yes, shooting it from a distance behind cover is the preferred way.

I didn't realize this was so common. Maybe I should start a business making bomb disposal robots for pokin' tires with. DonutFuckers™

Honestly if I had a tire shop I'd probably just get a 10 foot piece of steel pipe, tack weld a 16d framing nail to the end, and poke em from around the side of the car while wearing ear/eye protection. Not really that concerned by one unless it's real close to me... or real big, like that mining dumptruck picture that's been posted. gently caress everything about that.

 Whatever the bomb disposal method, the important thing to remember is that it must be recorded. For safety purposes, of course.

Eh for a passenger car tire I've done a few like that and they're generally fine as long as you don't poke em. Take out the valve core. I did poke one once though and ended up on my rear end.

Ever speared something that was charging at you? Trust me, you don't want to be holding whatever you pop that with, as it's going to be going the opposite direction at a high rate of speed shortly.

Platystemon posted:This obviously calls for a LASER. This could totally work with a laser of sufficient power. Tires are made to handle heat, sure, but the black rubber will allow you to heat a specific spot until it pops. You could even have a ballistic shield with a small laser-hole to hide behind.

When I worked in a warehouse, a co-worker popped the tire of a fully-loaded truck with one of the blades of his forklift. It basically blew him out of his seat and gave him permanent hearing damage. We all thought a propane tank or something had exploded.

Aside from the "how to pop it" talk, how the gently caress does this even happen? I've seen bubbles before, but wouldn't one weak point generally prevent the formation of others (as in excess air pressure and stress is going to build up on the original weak point, not create new ones). This had to be intentional.

I'd want to be as wide of the tire as possible, because once that bubble pops all the pressure is going to shoot more or less perpendicular to the sidewall. Though I probably wouldn't be stabbing the bubble anyways. Impale the tire somewhere else and I'd guess you could get a more controlled deflation. Or maybe a really long set of bolt cutters and clip the head off the valve stem.

Also based off of my experience with tires covered in titties like that, to have that many tells me it was run flat, the inside of the sidewall turned into rubber mulch, they aired it back up to roll it to the shop and there you go. It's too numerous, consistent, and all over that I find curbing or sabotage unlikely.

Also I just remembered I had pictures from the event I was talking about! Apologies for the quality, these were takin in 2006 with an ancient camera phone back when I first started at wheel works. For some reason we don't have a shot of the after. This was on a F250 diesel with a massive camper shell.  Oh, youth

To add to what 13 INCH DICK said, it's not excess pressure that creates the bulges. There's 2 layers of tire rubber, the reinforced inner liner and the outer, more elastic rubber. The inner liner degrades/gets worn through for whatever reason, air slips through it and into the gap between inner and outer, the outer layer expands to accommodate it (usually in a gap between steel belts), there you go. The rubber bulging in one spot doesn't prevent the inner liner from developing a hole in another, so that's how you wind up with multiple tumors like that. I'd agree that it was a flat that got re-inflated after sitting/driving flat for a while.

The other thing is that pressures and sizes vary significantly. Passenger car: 32psi, dinky little tire/wheel combo you can pick up with a few fingers at most. Stand to the side with ear/eyepro and stab a loving hole in it. Leave it bolted to the car so it doesn't decide to go flying around at random. Light duty truck: 35psi probably unless they're running 50 or 75 or something in a big one ton with heavy tires for towing. Same story, but use a pole. Medium/heavy duty truck: probably 70+ psi, big rear end tire, big rear end rim. I aint loving with that thing if it has a tumor, go curb the drat thing again and hope it pops.

35 psi is enough to kill if you get hit with all of it, it only takes 5 psi to rupture an ear drum. Now obviously when you stand next to a tire and pop it you're going to get less than that because the pressure is going to rapidly fall off with distance but it's still not something you want to gently caress around with. I like the sniper rifle solution.

That's what we always did in my shop (well, except one tire my idiot redneck service manager jumped in front of me and stabbed it with his knife; he didn't do that again). I always unscrewed the schrader, both for that and for normal deflation, but some of my coworkers would grab the stem with a pair of pliers and just yank them out. That was fun the first time each one in turn discovered that some manufacturers put the TPMS sensor on the end of a rubber valve stem.
