Put the tire on as far around as possible then make sure that part of the bead is in the center of the rim where it's lowest. The lowest part of the rim is smaller around. From there just work the rest of the bead over the rim lip a little at a time.

Some tire/rim combos can be a bear.

thanks...i've got one done...it helped a bit when i put it in the sun...maybe it made the rubber expand/stretch a bit!

Don't try to get that last part on all at once. Aim for the spots on the edges where the tyre wraps over the edge of the rim. Push sideways there because they'll be the least resistance, you don''t have to stretch the bead that way.

Also make sure you don't have too much air in the tube. At this point, if I have a particularly tight tyre, I just let the air out of the tube to relax the tension; enough will remain to keep the tube round.

You can also use tyre-levers. Rest the tip of the lever on the rim-edge in the centre of the unmounted section. Slide it up gently while maintaining constant contact with the rim. When the tip reaches the edge of the rim, stop pushing and slide it sideways as far as you can next to the section where the tyre overlaps the rim. Lift up and over. The trick to avoiding pinching the tube is to keep the tyre-lever in constant contact with the rim.

Then push the tyre sideways and inspect between the tyre and rim edge to make sure no tube is poking through. Work your way around the entire rim then do the other side. Sure it takes an extra minute or so, but definitely worth it to prevent a blow-out and flat tube later.

Dish soap on the bead. Tire lever. Watch out for tube-popping.

Tire in the dryer. Nice, warm and supple.
