The failure point while mounting is RARELY the tire. The failure point is normally the wheel. I’ve jacked 110+ in tires before.

Good to know, wow, that’s some serious pressure and cajones! (I’d try it myself but I’m pretty sure I’d pass out from anxiety at around 80psi 
)
Use plenty of lube and point the rim away from yourself when inflating. Shouldn’t be an issue.

Less about cajones and more about lack of sense. Lol
I’m not going to say you’re being too cautious, because beading tires is inherently a risky activity. That said, I’ve been to a lot of kart races and haven’t seen any tires blowing up. I’ve seen plenty be absolute bastards to bead. Tire paste and on a cold day sunlight are your friends. Soapy water is also helpful.
Regardless, here’s a time it went terribly wrong for me in my shop a couple years ago.
This was a cheaper rental kart tire in a difficult rim to mount tires on in a cold shop probably 40 degrees inside. Still, it knocked my glasses off and the blast from the tire and carcass gave me a decent bruise across the chest.
As they say, if you’re gonna be dumb you gotta be tough….or in my case you’re just dumb and get hurt.
I think another thing that a lot of people don’t think about is how they mount the tire and prepare it. If you go to seat it and the back bead is lopsided it can take a lot longer to seat.
With your setup I had a similar one, and I found that taking the needle out of the valve stem made beading tires WAY faster, and was super satisfying. Lower beading pressure too and a lot easier to drain to then re fill.

Good idea about the valves. With the open-flow chuck and the higher flowing inflator I bought it already seems like it inflates so quickly, but even in the open position, I’m sure the valves are still providing some resistance.
Glad you were ultimately ok after that accident. It sounds like you came off better than Dom’s friend’s finger did anyway, lol.

I remember meeting Jerry’s pal who had his thumb sewn back on after losing it mostly to an exploding mag. Wise to keep distance. (Doh you just referenced that).

THIS THIS THIS. A tire valve tool is <$5
- Valve stem tool
- Paste or some lube
- Band (or even a ratchet strap)
- Room temp tires and rims if it’s winter.
- If you want to go really safe… regulate the pressure on the compressor
/note to self: I need to figure out what that OG oEmbed issue is that keeps happening with links

Mounting our KA tires isn’t a big deal, but mounting those freakin LO206 6" tires on a 7" rim was a scary deal sometimes. I finally got two 2" wide motorcycle tie-down straps, cranked em down around the outer shoulder of the tire, and setup a lock on chuck with a remote fill valve just like some of you.
@Eric_Gunderson1 I have not seen tires pop, but I have seen rims fail. With the abuse they see, not altogether shocked it could happen. I wanted no part of my hand up inside one of those 90+ PSI bombs when mounting a 206 Evinco Blue!!!

Nothing will make you do safety squints and question if you’re going to meet a higher power soon quite like this

1000% the 6” on 7” rim hahahaha.
Rachet straps always scared me. The band is imo the way to go.

I’ve personally never had an issue or been scared of the 6 on 7" wheels. However the dirt tires are a bit scary at times even with a full steel tire band.
Get yourself some P80 emulsion for doing tires. It’ll change your life. It’s what is used in assembly of large rubber bushing into much smaller holes.

110 PSI minimum. Thank goodness there wasn’t Tik Tok or even cell phone cameras back then. No one could see how stupid we were.
Looking online this isn’t the easiest stuff to buy. Amazon lists it but the picture doesn’t match the manufacture. Where do you buy your p-80?
This will last you a lifetime and then some. Dilute with water. I put it in a spray bottle. You don’t need to spray it all over the bead. Couple drops and spread it with your finger.
Easily wipes off the sidewall of the tire.
That was the stuff I found too. The manufacturer is where I was confused. Internation Products Corporation is the maker of p-80 emulsion but on Amazon its listed as Dixon.
What is your dilution ratio?
Lane,
I do go to trackhouse to practice. However, I mostly to SCCA SOLO (Autocross) with my shifter kart. I do this all over NC (And the US). But I run with an Autocross club in the Triad (Well, I run it as well).
