Looks thick enough to scoop it off with a dull knife or spoon. if you wanna use products, go from sfe to harmfull, depending on what the wheels are made of. You don't want to damage those. I'd start with water. Soak em overnight in water, chances are it will come off easily after that. If not, you can try alcohol as mentioned in other comments. It looks thick, so it will need time to work in. Petrol or kerosine will work, but check compatibility with your wheels first.

Regular leather waterproofing wax should be fine. I understand grangers is a decent brand. procedure ... when the shoes are dirty or you notice they soak water. I used 2 brushes: one to clean off the dirt and another to rub in the wax. Make sure all leather had it's decent share of rubbing. You don't need much wax. I used 1 container for 10 years.
My last leather boots I used wax every now and then, which is good. I did not maibtain the shoes well enough nd hace some cracks in the leather. Had them for 10 years. now I'm following manufacter instructions (Lowa) and I'm impregnating the lether with chemicals and usung a soft leather balm for the lining. hope it helps
Is it there yet?
Why would you punish people for doing good?
Fedora or debian stable. I would recommend the KDE desktop environment as it closely reaembles what you're using now. try somw distro's and stick with what you like. I would not wait though. Just do it. welcome to the family
