Getting these to bead has been a nightmare. Any non-pyrotechnic advice?
Use a 180 like you’re supposed to?
Beyond that, use WD-40 and high inflation pressure, and a tire band… But I don’t recommend it.
Ted, in 4 cycle racing, everyone is using 210 wheels on 6.00 tires to free up the karts on these sticky tires.
OP, what brand tire and what brand wheel? Is it the bead not popping on or the tire not grabbing the wheel to accept pressure?

i don’t have the setup myself, but one of those air tanks that blasts out all the air at once work, for setting the bead. there’s a technique to doing it, but it works.
- Be patient.
- Be willing to go up to 80-90psi.
- Cold tires are near impossible. Keep them in truck, in sun, in house, in front of a heater.
- Use a tire band both for safety and to ease beading. Several designs available for around $100. It reduces the stretch of the tire around circumference.
Having issue with getting the initial seal so the tire will inflate? Or having issue with getting the bead? I typically had the most issue getting a seal when tires were cold. Sometimes it was tough to get beads to seat at a less than scary pressure, tire lube helps with that.
A very stiff R70 I’ve tried heat and ratchet straps. I don’t have a tire compression band. Yet….
Issues getting the tire to inflate initially…. I have tire wax, just cant get it take initial pressure.
Ah, yes. Those R70s are stiff. Get them warm (in the sun or inside by a heater vent). Also, put some dowel rods or boards cut to length inside the tire while heating to widen the sidewall. Let them set for a day or two and then put them on the rim. The sidewalls will be wider and grab the wheel easier. Patience and walk away whenever you need to. It is painful for sure.

Another small thing that can help is setting up an air chuck that works with the valve core removed so you can get air in faster at a higher volume. A second person can help squeeze the tire to help get the beads to seat enough to take air.

I use this for mounting the tire. It helps the bead slip.
This is the same paste that Discount Tire Center - they recommended it to me.
I have found that removing the core drops the bead pressure by about 20psi, give or take. With a power tool, it takes no time at all to remove the core (and it helps deflate the old tire easily). I’d definitely consider removing the core to be a mandatory step.
I also use a clamp-style chuck, both because I have to without the core and so I don’t have to have my hands as close when setting the bead.

so you can avoid this 
Never had one explode. Had a friend nearly lose a finger when a rim failed. After that I only used a clamp style chuck for beading up 206 tires. KA tires are much easier and less stressful!!!

For the especially hard ones I use a clamp on chick and put the tire a safe distance away, plug in the hose at the compressor and use the knob on the regulator to add pressure. Once the bead pops I disconnect the hose at the compressor. I don’t want to get hurt over a go kart tire but I also don’t want the task to take a long time. This has been working well for me.
