I've mounted those tires to Eastons and two different Mavic rims without problem over the past 5-6 yrs. What is it about the Ultegra rims? I went to Vittorias because mounting my Michelin Pros to anything when new was a major PITA. After riding them it was easier but the Vittorias are no hassle for me.
Never had a problem with these tires on other wheels ; the Ultegra are a different story, though.
Sorry, after screwing with these for several hours over a day and a half, I have little patience to try something like that. If I'm going out, I'm just going to go the LBS, where the mech can do it for me, and we can discuss mounting technique and look for solutions (and I can watch him do it).

Use a tire jacking type lever. They don't pinch the tube. My favorite is the VAR, because it is small enough to carry on the road with me. They are devilishly hard to find these days. Maybe all the macho boys saying that no one needs them is the reason you don't see them for sale in the USA. I dunno, but nothing works better to mount a stubborn tire.
The problem is that some folks can do it with just their hands, and some folks cannot. The folks that can do it like to tell everyone else how easy it is. And that may be true for them, but not for the folks who simply can't do it, technique and following instructions notwithstanding. As a cannot do it guy (until the tire is well worn in and stretched) about 30 years ago I found the VAR levers and have never looked back. They just work. Here is a UK source: VAR Tyre Levers RP-42500 - £7.50. My LBS in Houston was able to order me a couple of them a few years ago, so you may not have to go overseas for them.

What are you going to do if you have a flat out on the road? Call the LBS to come fix it for you? Not trying to offend you, just to make the point that you have to get on top of this thing. See my post about the VAR tool. It will solve your problem.
Also be sure you don't trap tube under the bead of the tire. You may be doing that to cause the pinch flats rather than actually damaging the tube with the tire levers. A LITTLE inflation keeps that from happening.

Apparently, the Vittoria Rubino Pros are a bit tighter in width than some other brands.
Those levers look quite useful! And yeah, I totally agree about being in the "can't do it" camp, even after following directions.

I was inflating the tube a little to keep its shape and to help prevent it from being pinched, but the Rubino was so tight when trying to finish the mounting that it stretched horizontally across the rim at the top and pinched the tube a bit. Every time. It was way too tight. Not sure if it's bc the Rubinos are bit narrower in their fit, or maybe there was a defect with this tire (it was new).

Start at the valve and make sure the bead is correctly seat around the valve area. You probably have to push the valve in to get it right. This is key to getting it right, always do the valve first. The talc and the dish soap will work, but can be messy. If no one is around spit on your finger and then put the saliva on the inside or the last part of the tire to be pushed on. Once the tire is on make sure that no tube is pinched under the bead by going slowly all the way around each side of the tire moving the tire away from the bead and be sure there is no pinched tube on either side. When you get good at this you can just slowly look all around the tire sidewall to be sure it is seated properly. I start with enough air to give the tube shape to get things positioned correctly. If I have a hard time with the last part, I let out some air.
Almost forgot, windex will work, and will evaporate leaving no mess.

Ah, yes, I did let air out at the end to try and get more clearance, but that didn't seem to help. I didn't lube the bead, however. Perhaps that would have helped a little.

Update: Some may have not seen it since it was buried in another response, but I ended up trying another brand tire (as Vittoria Rubino Pros are a little tighter in fit), so I gave Continental GP 4000 S2s in 25mm a shot, and they went on without a hitch.

I have a set of the 6700 wheels and it is indeed a PITA to get tires mounted. I was able to find the VAR tire jacks and I ride with one now, that solves the majority of the problem. Other than that, ensure that the first bead is completely out of the way and that only the second bead is in the center channel when mounting the second bead.
Have you ever tried to mount tubeless tires to these wheels? Now THAT'S ridiculous.

not sure about this particular setup but i do found that brand new tires need "break in". I personally fold and bend them back and forth for a while and make sure you do the mounting in a warm place.

I have the 6700's and haven't had any issues mounting tubeless tires, it's probably the tire/wheel combo. My first set was some Hutchinson Sector's 28's which went on without much effort and seated with a floor pump. The current tires are Hutchinson 25's that I needed cotton gloves and soapy water to get the last two inches on but didn't use tools. I'm currently building up a bike with a 6800 wheel set but the Schwalbe One 25's haven't arrived yet.

The last one I replaced had about 5,000 miles on it, it was not worn out, but got a huge cut in it.

Edit: the compressor didn't work either, the wheel is going back to Ribble. There are two holes drilled in the rim that are letting all of the air out. The same holes are in the rear rim so the rim must be compromised somewhere.

My bike mechanic changes tyres on the tubeless rims just using his hands, no tyre levers or soap. There is definitely a technique to it, you don't have to be Arnold Schwarzenegger, just need to use the right technique. But as many times as my mechanic has showed me I just can't get it, hence the change to clincher wheels.
