Question demount remove rear tire from wheel

Is it possible to demount, remove the tire from the rear wheel of a k1200s with spoons, tire irons?
I have a nomar, but I can't even get a spoon, tire iron in between the tire and wheel.
I have heard it has to be done on a machine with a special adapter.

Hi,
I've done all my tire changes myself right on the garage floor. Sounds like you haven't broken loose the tire from the rim. When you've done that the spoons will work.
To break the tires loose from the rims, I've attached 2 2X4's 4' long to a shed side post/pole and attached a 2X4 between them hanging down. I then place the wheel under that and on top of a 2X2 under the rim. levering the 4' 2X4's down and the hanging 2X4 on the edge of the tire, little effort to break the tire loose from the rim.

You can buy a levering tire breaker for not much money if you don't want to make one.

Hope I was of some help and understood you question correctly.

Due to heart health, the Dr says not to ride under 40 degree air temp. Ugh! Now it is harder to get my 18000 miles a year in just in the summer. Guess that stopped my 20 degree rides now.

Re: demount remove rear tire from wheel

Heavyweight sport-touring bikes require larger tires with stiff sidewalls. Plus the BMW rims have very little center dish to them, so it can be a hassle to change tires . . .

For reference, the large center hole on the K12/13 rear rim means that the wheel fits onto standard car tire changing machines.

I've gotten local independent tire shops to dismount/mount/balance the rear tire on my previous K12GT several times. National tire chains can shy away from bike rims for "insurance reasons" but the local guys will usually do the work for cash.

I have done the job with a No-Mar tire changer, and also by hand, but it's usually worth a couple of bucks to me to just have it done while I watch.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Re: demount remove rear tire from wheel

What I'm trying to do is. I have a K1200S wheel with a new tire. I want to mount the wheel & tire on a R1200GS. Can I just run the tire backwards? The wheel will be running backwards also but I not as worried about that.
I took the wheel to an auto tire shop, he said his machine could not do that type wheel with the shallow center.

I am very confused. Are you asking:

1. I have a K1200S wheel with a tire mounted and ready to use. I would like to attach it to my R1200GS by inserting it over the five mounting bolts and tightening it down. I realize that the wheels mount on different sides of the bikes. Will it work?

A: I dunno, but assuming the bolts line up and match the required depth on the wheel, I wonder if the K1200S disk rotor will line up with the brake caliper on the R1200GS. It should be easy enough to try and see for yourself.

... or are you asking:

2. I want to remove a K1200S tire from the rim and mount it on a K1200GS rim. It is very hard to remove the tire from the K1200S rim. Any suggestions?

A: Your NoMar tire mounter should include a good bead breaker. Make sure the air is out of the tire and the valve removed from the valve stem. Use the bead breaker to separate the tire from the rim, and then use the NoMar bar to remove the tire as always. From what I have seen when others do it, it takes a lot of energy, effort, and some practice to remove tires from BMW rims such as your K1200S, even when you use a NoMar. Good luck!

If those were not your questions, would you please explain more carefully what you are asking. Thanks.

Re: demount remove rear tire from wheel

I have a wheel and tire from a K1200S. The K1200s final drive is on the left side and the brake rotor is attached to the final drive. I want to use this wheel on a R1200GS. The final drive is on the right side. It also has a brake rotor attached. If I just bolt the wheel and tire on the tire will be rotating backwards. I have heard this would be bad with a radial tire.
I will also have to change the muffler for clearance.
My question was, how do you get the tire off the wheel?
The K1200S wheel does not have a depression or relief for the tire bead to fall into so you can lever the tire off the wheel. Also the tire is very stiff.
My work schedule won't let me drive 30 miles to the nearest motorcycle shop with tire changing equipment. I showed it to an auto tire shop. He said his machine would not work on that type wheel.

What I'm going to do is, find someone to take my wheel to the motorcycle shop, leave it, then find someone to pick it up. It's only time and money.

Yeah, that was stupid regarding the rotors - I was thinking front wheel. Now I get what you are asking, but don't have any helpful answers. Good luck!

Re: demount remove rear tire from wheel

The rim must have a drop well, maybe not a deep one, but it must have one or you can't change tires period. You do want to swap the tire around so it rolls in the right direction. Once the bead is broken try wedging small blocks of wood under the lip of the rim to push the tire down into the well. Then insert the spoons on the opposite side of the blocks. Leave it sit in the hot sun for a while and the task will be easier.

Re: demount remove rear tire from wheel

OK, I just got the wheel & tire back from the motorcycle tire guy. He ran into the same problem I did. We were both trying to take the tire off from the face side of the wheel. He turned the wheel over and tried from the back and even though you can't tell from the outside looking at the wheel there is a little more room working from the back side.
$24.00 well spent. got the job done and learned something.

Re: demount remove rear tire from wheel

I use a Harbor Freight tire changer with a some UHMW blocks to stop wheel
marking and have changed tires on: K1200LT, K1200GT, K1300GT and
R1200GS and as a tire guru says if you are sweating doing a tire change you
are doing something wrong. The GT tires are the most difficult to change
out!! I spend more time balancing the darn things than pulling and putting
the rubber on!!
