Pliers like those are purely for fitting difficult tyres, when you might otherwise be tempted to use a normal tyre lever to get the last bit of bead over the rim. There's also the
Simson/Kool Stop type, and the
Var lever (mediocre for removal. but considerably more portable than the al;ternatives if you know your tyre is difficult to fit)
For workshop/home use, I use
Lezyne Saber levers
On the bike, I use two steel levers similar to
these (guaranteed not to bend or break whilst removing even the tightest tyre).
If I know my tyre is a tight fit, I'll often take a Var lever as well.
My experience is that the levers that are flat section all the way along are a fair bit better than those that have a round central section.
I've also acquired a tyre glider, now in the saddlebag awaiting proper field testing (seemed OK at home).
