Use some muscle. If that's not possible, visit your local bike store or Walmart and buy these or something similar:

https://www.amazon.com/Pedros-Tire-Levers/dp/B00CQTVU2A

Put one on each side of the remaining section and pry the tire on. Be very careful not to puncture the tube. It's easy.

BTW, I used screwdrivers for years but wouldn't recommend it.

With that much of an overlap, my first guess would be that you're trying to fit a 622 mm BSD (bead seat diameter - where rim and tire overlap) tire onto a 630 mm BSD rim.

If you're certain that's not the case, revise your technique. Save the bit closest to the valve to last. Start from opposite, push the bead into the center channel of the rim to free up as much bead as possible for the last heave over the rim.

And next time, try be a bit more descriptive in your headline.
Simply "help" isn't much use. "Help with tire mounting" or something along those lines makes it more likely to get good answers. And is easier for answerers too.

Look at the sidewall of the tire and see what size is marked there. There should be something like 622-23 or 630-32. What bike is the wheel off of? If it has "27 inch" wheels (ISO 630) and the tire says 622-X it will never fit.

I think I have it right...both 700c rim & tires.
I'll try to move it so the area by the valve is pushed on last.

And, will do with the thread title...thanks!

I know the old tires were 700x23c...the ones I bought were 700x25c. Could that be an issue? Advise I got from here was that the 25mm wide ones would provide a better ride.

No, that's not the problem. However even tires of the "correct": diameter can vary in how easy they are to install and some rims are tougher than others. It depends on how the manufacturing tolerances add up.

The ultimate tire installation tool is the Kool Stop Tire Jack:

https://www.amazon.com/Kool-Stop-Tir...tire+bead+jack

If it won't install the tire, nothing will.

Muscle and you have to make sure the rest of the tire that's on the rim is seated or fully bottomed out, massage it back and forth. Get tire irons and work close to the end, inching on, watch you don't pinch the tube. Also, make sure there's no air in the tube at all.

If you need the tool to install the tires you had better plan to carry it with you on the road. I won't run a tire/rim combination I cannot easily change by hand. Consider that tires preferentially flat at the end of the day, when you are tired and it is raining; do you want to be wrestling with a difficult-to-mount tire under those conditions?

I doubt there is a tire/rim that is impossible, or even hard, to install with the Pedros tire levers that were mentioned earlier. Park has a similar tool out now. I like some air in the tube while I am getting the tube into the tire, but once its all inside I let all the air out, then start to work the open side of the tire into the rim. Sometimes the last 4" or so are stubborn and sometimes not. If stubborn the Pedros lever WILL get it on and I haven't cut a tube yet in over 3 years of using them.

This. The Pedro's levers are dollar-for-dollar the greatest, most satisfying bike tool ever, vs. trying to do without. I can't believe the wasted struggle I used to have.

As others have said, sometimes even the same combo of sizes just do not go on with the same degree of difficulty by hand.

I also like some air in the tube at first, to give it a bit of shape & reduce twisting inside the tire.

I got some new custom wheels last year and had trouble mounting 700x23 tires. A Bike Forums member recommended a VAR tire jack lever. Works great.

My tires look like that on the low profile rims I use. If you added air to the tube (I do) you may have put too much in. Try letting some air out. Then just work with your thumbs until it goes in. You have to count a millimeter as a big victory. But it will go. Check often to make sure you are not pinching the tube and that the tube is not already caught between the rims bead seat and the tire bead some where else on that side.

If you added more rim tape or a rim strip, it may be taking up room that the bead of the tire in the rim wants so it can give room for the part of the bead you have not gotten into the rim yet. I think using tools is dicey, but I have resorted to levers when desperate. But that frequently also wound up causing a tube puncture.

The other week a friend and I swapped front and rear tires on his bike. He has one of those impossible combinations, and we wrestled mightily. Took both of us working together to get the now rear tire on the rim. The very next morning he flatted that very same tire.

I had this problem with conti GP 4000's, they just wouldn't go on the rim.

The last part that you're stuck on, I just point it downwards towards the floor, supported on either foot. Then I grab the tire and try and squeeze with both hands outwards and towards the part of the tire I can't set on the rim making sure the bead is as close to the center of the rim as I can. It won't feel like you're doing much, but that's usually enough to stick a Pedro's tire lever underneath and ease the rest of the bead into the rim.

Hope that helps.

The trick involves the side of the tire that you didn't show in your picture.

1. Stand up holding the wheel vertically on the floor with the last bit of tire on the floor.
2. Pinch the tire beads which have already seated on the top part of the tire together. You don't want those beads to seat just yet.
3. Grab the two sides of the tire, one in each hand and try to push them straight down. What you are trying to do is to accumulate all of the slack between the tire and rim in one spot.
4. In most cases, you should now be able to pry the last bit of tire onto the rim without the need to use any tools.

One should not need to use a tool to seat a tire to the rim. Tools should only be needed to remove the tire, not put it back on.

The whole trick is massaging the rest of the tire back and forth all the way around often as you work the bead on. Once you got the tire on, push the valve stem up into the tire for a second to make sure tube around the valve is free. You have to be able to do all this on the side of the road.

Think road tires are tough, try one of those yellow Conti trainer tires.

Looks like a piece of cake from that video...I assure you, this was nothing like that... Maybe my combo of rim & tire?
First of all, my rim doesn't have a deep well like that at all. Second, the tire was a folding tire, and not the wire bead... Not sure if that makes a difference at all. I know just getting the first bead in was a pain...
Well,I finally got my tires on yesterday. I had to use the heavy duty levers from Park tools... My LBS didn't have the Pedro levers. The third time was the charm...I pinched the tube on the first 2 (assuming with the tool) attempts... It's possible they were just cheap tubes? They were cheap Bell ones from Walmart. So after killing the 2 new tubes I bought, I reused the ones on the bike and both of those worked! Took about 4 hours total between 2 nights to get them done! I now have the experience of changing 4 tires and it became much easier. I can probably change one in about 5-10 minutes now. I really do think it's just a bad combo of rim and tire after watching a bunch of videos on the subject.
Thanks for all the help on here!
Oh and here's a pic of my tires if anyone cares!

Bike looks straight fire! Love the colors.

Tubes are, you know, variable. Some just work, and some fail immediately. Sometimes it's a pinch flat, or a rough spot in the rim, or a foreign object, or just an utter failure at the seam of the tube or the valve stem. Super frustrating, but you keep on with it & fingers crossed next time! :-)

My current tires are folding tires. I just go them near the first part of the year. This is my first experience with folding tire. I thought they were harder to get on than the wire beads I'm used to. But they seem to tolerate the force required to mount them.
