I can do this... "wheel removal"

I have a 77 R100/7 and it needs a new rear tire. I was going to wuss out and take it to an independent BMW repair shop but I think I can at least remove the wheel from the bike. I have some mechanical experience and some basic tools. On my 73 Yamaha rd350 I've rebuilt carbs, rebuilt the master cylinder, and removed and changed the front tire. But that bike was a piece of crap and I am a bit leery of screwing up my BMW "dream bike". Is it really as simple as it looks? I saw some other threads about propping the center stand and strapping it. Put some weight on the front tire. Give it some clearance. I'm not sure I could stomach the other option I saw about putting her down on the right side to remove the wheel. Gas leaks? Maybe I could do that if it is easier..

On a side note. I know the is a never ending topic but....

I have the Metzeler ME 88 120/90 on the bike now. Do all 120/90's fit or just ME 88's? The ME 88's are tubeless. Can I go with any tubeless tire?

My tire choice.

I would love to get a dual sport tire for the rear. I know my bike was not intended to be dual sport but it looks cool. Are there any that fit my bike?

I'm not dead set on the Dunlop K70 Vintage Motorcycle Tire. I could be swayed.

My driving style is mainly a 20 mile round trip to work on country roads. Maybe a summer day trip but mainly short hops

Thanks in advance....

Yes, you can do it.

these days I have a lift, so I just strap the front end down. In the old days I would use a small screw-type jack under the swingarm to tip the rear end up. Run a strap from the center stand through to the front axle to keep the stand from folding under as the bike tips forward. Some folks remove the front wheel and put the axle back in, this gets the rear of the bike up high enough to clear any luggage racks that might get in the way.

It's not that hard to change tires on this bike, IMO you should at least try doing a mock tube repair once the wheel is off.

the aspect ratios of motorcycle tires are just that - ratios that represent the height to width but should not be interpreted as exact measurements - unfortunately. Some 120/90 tires may fit, some may only fit with letting a bunch of air out getting it in/out. and some will rub dangerously on the swingarm once installed. The same tire "size" from one manufacturer to another may vary by several millimeters in width and height, and even from model to model within the same brand - though that is less common.

If you are not looking for a super high mileage tire, but want a nice "sticky" one and are looking to repalce a 4.00x18 rear tire I can recommend the Bridgestone BT45 in 110/90 "size". Not fantastic for dirt roads, but not too bad, and very nice on pavement.
