Apologies if I've missed this info, but what are the dimensions of the rim and the tyre? As well as the max pressure, is there a minimum quoted? 80 is fairly low for what I assume is a 23 or so tyre.
As per previous posts, put some air in the tube before putting it in. Helps the tube get located properly well up in the tyre. Take care with the valve stem and make sure you push it up so that the tube is not trapped under the bead. Fit tyre (best to avoid levers, almost always possible to do by hand), put some more air in, go round each side of the tyre and do a sort of push-pull-lift to ensure the tyre is well seated.
Then inflate.
Folding tyres have a kevlar or similar flexible bead. Non-folders use wire. Both are clinchers.
