I bought a Cannondale ebike that uses WTB STX i30 TCS tubeless ready rims with Continental Race King folding bead tires that are currently setup with tubes. 29x2.2

As soon as I got my first flat I discovered that I could not remove the tire or even break the tire bead free from the rim. The mechanic at a shop had to use an undersized tire "wrench" pliers to crush the tire enough to free the bead.

Anyway - I've been around the block - and know how to change tight tires. I've never seen anything like this. Can anyone suggest a very loose fitting (wire bead) tires they know about from experience?

I just want the loosest possible 29x2 or 29x2.2 tire possible. Typically a mix tread ebike rated tire for light gravel or pavement use? I need something I can fix a flat while on a trail.

.

Many if not all tubeless ready rims will have tiny bumps just on the inside of the bead seat that help keep the tire bead in place. It does make it a little bit harder to remove the tires. But not that much. I can still do mine by pushing it off with my thumbs. Or you can simply use a pair of channel locks with padded jaws or buy the correct pliers.

I don't think you'll find that you can assuredly find that any claimed loose fitting tire is anything by unique to the person touting them as loose. Your experience with that same tire will just depend on how well you understand what you have to do to get that tire loose.

find an Innova tire... they sometimes fall off on their own when deflated.

most Kendas mount/dismount by hand.
same for most Chicken Skins, err,,, CST tires.

I don't know any thing about Innova - But I hear you - "Chang Star" baby - those are some "fall of the bone tires" - I was thinking about them.....

go to your local wally-market for Innova tires... cheap as dirt, and crack if the sun comes out in the next county over.

typically tight tires to avoid.. Maxxis, continentals, vittorios, and schwalbees.... oh, and certain annoying WTBs too, eh?
i install Maxxis tires for the quiker sale value... that bold yellow lettering is the key, i think.. around here, bright colors equals fast sales!

another brand that tends to run loose... IRC, but i don't see them much now... probably got sued, then changed name.
strangely, i've had some really loose Schwalbees in the past.

panaracers trend to the snug side, but i don't care... they are great tires at a fair price.

The whole point of having tubeless tires, is so you don't have to 'fix a flat while on a trail'. You already have the tubeless ready rim and the tubeless tire. I am guessing Cannondale already put tubeless tape on the rim. So all you need to do is put in a tubeless valve stem and then pour sealant in there and you are good to go.

Yeah putting a tube in is kind of making a problem that doesn’t need to exist.

Got a Creo last year and found the OEM 44mm a bit large for mostly road so after reading reviews got a pair of Conti 5000
gravel 32mm. Wow!! After 45 min of prying and levering on the DT Swiss AL rims (tubeless but Creo has tube as supplied)
I could not get the last 14" of tire bead over the rim at home with a variety of tools, but careful not to groove or cut the rim edge.
Sent them back as had the same thought, if I can't mount at home with tire plyers I would be up the creek with a flat on a ride.
Panaracer gravelkings SK have reasonably good reviews and were easy to mount (by comparison) and tread looks good at
~4000 mi on the rear. SK series have moderate tread.
