I'm a long time biker but am used to big steel spoke wheels. I recently got into the whole scooter thing. I bought a Puma Valentine 50 and installed a 83cc BBK for the wife and I bought a BMS Chelsea 150 for myself. Both came with the cheap stock Chinese tires which I promptly removed and replaced with Shinko white walls, which I'm very happy with. Problem is, I boogered up every rim no matter how careful I was when I swapped the tires.
What am I doing wrong? Is there a careful way of doing this?

it's a little too late for this, but tire shops will change your tires for you, especially if you purchase the tires there.
speaking of chinese rims, get rid of those OEM stems right now.
mine got so bad that i was afraid of checking the tire pressure for fear they would pop out and splat me right in the eye.
my ride had the 13" rims and took the 5/8" stubby stem.

I use old garden hose slit down the middle then put the split over the rims edge.
No more Buggered Rims.

Shampoo bottle here. Cut off the front and back to however large piece you need. Small enough to pack with you. Tough enough for 3-4 tire changes. Make sure it's the shampoo bottle and not the conditioner one.

Thanks guys. Much appreciated. I like the garden hose idea. I think I'll go with that next time.

romei Did you use tire mounting lube? Soapy water works also.

I have a great way to change tires, I just did it on my buell.
First you need to use a grinder to cut the tire . make a a slit in the center of the tire from front to back , about 9 inches. Next make another cut from side to side, as far down as possible without hitting the rim " make this cut at the center of the first cut so it makes a + pattern " this will weaken this area of the tire and will have the tire just about ready to fall off ". Next use your tools and pry out so the sharp part of the tool is pushing against the tire to pop the bead. Next prying the same way at the center of the side cut , pull the tire over the rim so u can then use the grinder to cut through the metal bead as u hold the tire out past the rim . do this to both sides and the tire falls off.
Now this is the easy part " installing the new ones " . put the rim in the freezer for at least 30mins and either let the tire set out in the hot sun or if its not that hot out , put the tire in the shower with the water on full heat for about 10 mins or so. When u remove the rim from the freezer you will want the tire to be free of water " inside " . now quickly put some soap around the tire where it will contact the rim and quickly push the tire over the rim while it is still slightly shrunk from the cold freezer. My 13 inch scoot tires went on with almost no prying , so did my 16 inch buell tires. The first side always goes on with no prying but the second may need a little . also make sure the contact area does not dry and stays wet and soapy. Each tire should go on in under a min.

Even with the rim protectors a little duct tape on the spoons can help too. There are also nylon mini pry bars used by the auto trim and upholstery folks that work well too.
