run flat car tire?

[mikehallbackhoe]

have been lurking in the shadows over at the gl1800 darkside forum, and the they seem to prefer a 195/ 55 16 runflat ct, has anybody tried a rf tire? also has anybody tried the 195/55 16 size on a valk?

I've read the same and will definitely be trying a runflat CT next, although I don't know how long that'll be.  I've put about 6k on my Goodyear Assurance and you can't even tell it has 100.

Would a run flat tire end up being too wide when there is a problem with it (running it when it goes flat)?  Just asking.

They only deform on the bottom edge...well away from the swingarm.

From what I understand, they have a much stiffer sidewall.  Please explain to me the sidewall in relation to cornering forces.  Does the sidewall need to give to help keep the tread flat on the ground in a corner?  Wouldn't a stiffer sidewall tend to lift the outside of the tread off the ground quicker than a more flexible sidewall?

I am a little concerned about giving up some cornering traction to gain the runflat technology.  The GW'ers do not need to worry, as they do not lean as much in corners as the almighty Dragon!

Help me understand.
Thanks

I have no experience with the run flats. There are several methods to make a tire run flat, but stiffer sidewalls is not one I am familiar with. The ones I've seen have a center ridge which maintains some height when deflated.
I will just run my regular car tire since I have never had a problem plugging one if it goes flat.

Valker:

I got the part about the stiff sidewalls over on the 1800 Darkside forum.  Lots of comments about how much stiffer the sidewalls are.  Sounds like a LOT stiffer.
