Impossible rims to work with ?
Had my hybrid bike for 4 months now And got a puncture two weeks ago so switched the inner tubes and it took me 5 hours to put the tyre back on .
So I decided to change my tyres to some puncture resistant continentals Hoping they’d be easier to work with but they were even more difficult and couldn’t get past the final bit of the tyre
I called a mechanic And he said they were the most difficult tyres/rims he’s ever worked with but eventually after 1hr30 we managed to get them both on and it was a two man job
we used about 4 tyre levers
ive replaced tyres many times before within minutes However these rims are insanely difficult to work with
should I invest in some easier rims ? Ideally I’d like to be in a position where I can change Innertubes at the side of the road

Change tyres. I think Coniti’s, in general, have a reputation for being difficult. Ask the mechanic for suggestions.

Both tires and rims add up to this. Each are made within tolerances. Both vary in the production process. Some rims are known to tend on the big side of within tolerance. Likewise tires can be on the tight side. Talk to that mechanic about what tire he would recommend. (I've found Vittoria and the Panaracer Paselas to be not too hard to mount but ask and try. I haven't used your rims and not all of those tires.)
Four hands, 4 irons, 90 minutes. I see Murphy behind that tree.
Edit: tubeless rims tend to the larger diameters for security with tubeless ties. Sounds like that tire/wheel was pushing both the limits.

Yep, this as at least the third thread about these diabolical tires.

I have however reached out (PM'ed) to the OP and again offered a video call to demo the technique.

I’ve replied to your pm Barry, much appreciated
the method Barry pm’d me worked wonders when I did my stock tyres 2 weeks ago. When I got my continentals I did it the opposite way ! That should explain it
over time will the tyres become easier as I wear them in ?

It just comes with experience.
My Velocity A23's with GP5000TL's were by far the tightest tires I've ever had the mispleasure of mounting. They were so tight I could not even get the first bead on with out levering it on with tire levers; Let alone the second bead. Still the wheelset took under 45 minutes, in total. 5 years ago a similarly tight single tire would've taken me hours & broken at least one lever.
Don't be discouraged.

Try Continental SpeedRides. Outstanding tires for most terrain and pavement, and easy to remove and remount. I've ridden a set on my favorite hybrid for three years and still haven't worn 'em out, although the rear is getting close. I'll replace 'em with new SpeedRides. They're that good.
Yeah, some Contis are a PITA to mount, but not all. Ultra Sport II are almost impossible without a Kool Stop bead jack on any rims I've tried. I still have 'em but mostly for use on the indoor trainer now. I always carry a bead jack in my pocket when I ride with Ultra Sport II tires.
For most outdoor rides I've switched to Conti Grand Prix Classic skinwalls, which I can mount with just my hands on a good day (depends on joint pain after 62 years). Sweet tires for the money. No need to carry a bead jack.
Part of the trick to mounting uncooperative tires is ensuring the bead stays in the recessed channel as you work your way around the tire. Often the bead will slip out of the recessed channel, so pinch it back together, hold it taut, and try again. But a bead jack still helps.

I don’t have enough money to buy even more new tyres
if I get a flat again ill try Barry’s technique.
I hope over time they get easier to replace
let’s hope I don’t get any more punctures foremost

Hope is not a plan. When your hands heal, you need to practice until you are confident in your technique. You will get flats, and need the confidence to deal with them. If you don’t, it will turn into an excuse not to ride, and none of us want that.

I tried for 7 hours last time. It’s a two man job

According to decathlon lots of other people have the same difficulty
If I get a puncture again I’ll take the advice I was given and remember to feed the bead right into the middle of the rim to allow for more slack
