Reddit reviews Slime 20088 4-Way Valve Tool with 4 Valve Cores

They're valve cores for Schrader valve stems (car/some bicycle tires)

You can pull the valve cores out of the valve stems, or just loosen them so they leak. You aren't actually damaging anything like slashing the tire, but you are still going to ruin their day, and they will most likely be too stupid to know what the problem is. They will get a tow to a tire shop. If the tire shop realizes they are dumbasses, they should screw them from there. The tool is at every parts store or walmart. I keep one in the car.

      You can't predict every failure, but this will fix most major issues enough to get you to a shop or a safe place to work. Give the Jeep a once over, front to back, left to right. Drive it at highway speeds for 30 minutes and source out any shakes, squeaks, rattles, buzzes, etc.
      
      Hope this helps.

For nationwide roadside assistance, I've been really pleased with Coach-Net. AAA is regional and there's some reports on the RV forums that there can be issues outside of your region.

I've also had great luck with this multi-purpose inflator. I use it on tires, air beds, and to inflate my stand up paddle boards with a DIY adapter.

It's a good idea to carry a valve tool and some extra valve cores too.

Weird shit will break when you're in a hurry or in the middle of nowhere, or when the local weirdo takes an interest in you!

Yep. For a mere $2 you can have a tool for all asshole parkers.

I'll just leave this here.

A simple valve tool can remove the core from the tire valves. The tires (which remain undamaged) go flat; hooking up a compressor won't re-inflate them.

Only think about this if you see the driver park this way deliberately and need not have done so. Be sure to leave the tiny valve cores (descretely) someplace on the car so you can't be accused of theft.

Solution: back out, let them have the spot. Remove the cores from their valve stems and leave them under the wiper blade.

> So this is where I'd grab my pump and let every last bit of air out of their tires.

Why not use one of these?

The best part is that nobody will be able to fill the tire with air initially and very few if any carry a tire valve on them. Now that I mention it, I need to put one back in my car for asshole parkers.

Or they leave it where its at, walk/bus/uber to the store and pick up a valve stem tool with valves for a few bucks and a portable compressor (a mini bike pump also works, but takes longer) most insurance covers at least one tow a year, so they could even get it towed to a gas station next to one of those stores to air the tire up after installing the valve stems. But most tow trucks will have a portable compressor and it would just hit your roadside assistance. Definitely under the $500 deductible and an inconvenience, and I do appreciate you advocating against slashing of tires. But it's not too hard to replace valve stem issues.

A) no.

B) You need to remove the core with a tool (cheap and sometimes is even included in a package of slime).

C) Check the clearance you have. Different manufacturers sizes do not always fit the same. I have Schwalbe 40's that fit where a Kenda 40 does not. You can measure the gaps and go from there. Your bike manufacturer may have suggested sizes as well.

valve core tool

I just want to expand to the flat tire idea I've seen elsewhere in this thread. All tires use a valve stem to let air in and out, in the mechanic world when you change tires you use a little tool that takes the valve out of the stem, meaning all the air comes out and there is no way to put any back in without replacing the valve with the same tool.

Point is, you can empty every tire in under 1 minute, and he can't just fill them back up since the entire valve is missing. If done at the right time this can wreak havoc on his life, and be expensive if he has to call for a tow or similar. And since most people don't realize the valve can come out, he will most likely be forced to pay a tow and repairs. Rinse and repeat as often as you want to fuck with him.

The tool itself is cheap as hell too. Here's a link for $2 on Amazon. Though you may be able to find one similarly priced at a local auto shop.

So is that needle thing the valve stem core? And i use a tool such as this?

Is this short little video all i need to do? Been seeing some videos where they "break the bead" of the tire, do i need to do that? Or is that for replacing the entire valve stem, not just the valve stem core?

How do you know it's the valve cores thats been removed? Do you see a gaping hole in the valve stem? If so order some of these and get a pump

Hey, they can do it, but then what? You're really going to leave your car unattended after jacking a spot I'm waiting for? That's not a great idea if you like your car and want to preserve its present condition.

​

FWIW, one of these comes in handy for removing the valves from someone's tires. No damage, just a major inconvenience.
