paranoid about airing up loose fitting tires
So I mounted a 2.35 IKON on 24mm ID light bicycle wheels. It went onto the wheel with a quick flip of the tire lever. No pain at all. I'm paranoid that if I air it up its going to blow right off the wheel.
The previous tire, a 2.25 Ardent, was an insanely tight fit and that just seems like how it should be.
Has anyone had experience with this situation? I hope I'm just overly paranoid.
Tire with Cut Bead Pressure Test, by Damon Rinard
Tightness doesn't matter unless you're using rims which have no bead hooks.
If your rim looks like the one on the left, a loose tire can be an issue. If it looks like the one on the right, it won't matter how loose or tight it is.
Mine wheels are hookless. Darn.
my local wheel builder has built up lots of LB wheelsets. all sizes: 27.5, 29, 29+, b+, and fat rims. all tubeless obviously. he has nothing but good things to say. including that they are built to high tolerances.
i had a 5" tire blow off a cheap 80mm rim while i was setting it up ghetto tubeless, literally in my face. it wasn't fun. i had built up the center of the rim with foam and rim strip and the tube, and it was well lubricated with stans.
i think part of my problem was that the tire was not centered perfectly on the rim, and i had built up the center quite a bit, and it was a cheap rim with terrible tolerances, and i was mounting a monster tire, and it was ghetto style.
i don't have any first hand experience with the Ikon so i can't compare. i would guess you'll be ok. if not you may need to find a new tire, after you rinse the stans out of your eyes and ears.

"Fully rigid" isn't a thing.
With loose fitting tires you have to be careful when initially inflating and check them at very low pressure to make sure the bead is even on both sides of the rim (correct if necessary) but once they are set then you need not worry about bringing them up to full pressure.
Put on some ear muffs, turn your back, and see what happens!
Thanks for all the input
I ended up making the bead slightly slick with some turtlewax protectant with the intent of inflating the tire at very low psi. It actually worked and the bead fully seated after letting it sit there for a few hours.
Of course now I'm paranoid its going to blow off on the trail after the bead stretches. Despite the fact that these are well respected Light Bicycle wheels, very common Maxxis Ikon tires, and a fully seated bead.
The human mind is a wonderful thing.
I had a Panaracer blow off my Derby hookless. I aired it up to about 30 psi and bang, Orange seal all over the place, a brown stain in my underwear and my neighbor running over to see who I shot. The Fire XC is a little narrow for a 40mm rim, but it wasn't a lose fit. It just didn't work for some reason. Ray told me that was the first report of that happening. I could get it to stay on at 25 psi, but I was affraid to ride on it. its to bad, because it looked good and I think it would have worked well.
Well, of course it didn't work.
The tire is a Fire XC, and the rim is clearly marked AM.
Maybe you could have fooled the rim with the FR casing?
You shouldn't have any problems with Maxxix tires unless they are defective or the rim is out of spec. Had a cheap Vrubber tire blow off a Nox rim. Way too lose going on no tire lever of force required. Aired it up to 30 psi. Everything looked good. Hopped on it to spin the stands around and bang tire off stans all over the rear triangle. Never should have bought a POS tire
I know far to many people who have hookless that have mounting issues.
What is the purpose behind hookless anyways?
I drive more when the streets need repairs! -'95 ZJ
Easier to manufacturer and enables ability to make rim walls stronger (carbon)
