I haven't run one...but I really see no reason to. CTs have thicker sidewalls and tread than MC tires, so they are already much more rugged and more puncture resistant. I would think going with a runflat would make the tire harder, especially the sidewall...and our good-handling CTs depend on the sidewall flexing in the corners. So I have no plans to try a runflat.
Answer this- you have toured on MC tires...did you ever use a runflat? (I don't believe there even is such a thing for MC tires). Even if you put a runflat on the rear, you still have the more delicate MC tire up front.

This may help this discussion -- I have been using Car Tires on my Goldwing 2 Years now using both Run-Flat and Non-Run Flat models. The Run-Flat models get less Mileage and do run on the edge more so the the Non Run Flat but we are finding the Rubber is sticker than a Motorcycle Tire and we only run 30 to 34 PSI in them even on a Heavy Goldwing fully loaded pulling a Trailer even. The Contact Patch is longer front to back so to speak with there being still more rubber on the Road then a Motorcycle Tire even in a steep corner.
We have found that the Run-Flat does corner OK. Personally I don't like the Car Tire models with wimpy Side walls like Falken as they require a lot of Air Pressure to prevent to much sidewall flex. What I have settled on is the GoodYear TripleTred Non Run Flat Car Tire which has a fairly Stiff Sidewall not needing those high pressures and has exceptional Mileage with 45,000 Miles being reported with the heavy Goldwing.
That being said the first Car Tire I tried on my ST1300PA was the Pirelli Run-Flat but it would not Fit on my ST1300 as when I tried to install it I could not compress the Sidewall at all to get it by the ABS Sensor on Rear Swing Arm.
I have jumped at the Hankook after hearing that it fits the ST1300 OK and just may try the GoodYear TripleTred 205/50-17 when I wear out this Hankook later. I really hope some other ST Owner tries out the GoodYear and reports back on whether it fits so we all know. The GoodYear has 2 Steel Belts = 1 Polyester + 2 Nylon Tread Plies just like the Hankook BUT it has 2 Polyester Tread Plies in Sidewall whereas the Hankook has only 1 Polyester Sidewall Ply. I am gun shy as I paid to mount the Pirelli then UN-Mount it on my Rim and took a Hit trying to exchange it for a Car Tire for my Goldwing.
Another Gem of INFO is I am using the Bridgestone G709 Front Tire on my Goldwing and found out to my surprise that it actually runs almost as well as a Run-Flat when you lose all air. What happened with me is I had installed a Doran TPMS (Tire Pressure Monitor) then on a ride on secondary roads at night the Doran Alarmed me of Air Loss. As I slowed to a stop I noticed my Goldwing handled very bad as speed reduced.
Yes all the Air was gone as the Goldwing so called Metal Valve Stems actually have rubber attaching them to the Cast Wheel and had broke off. Here I was 60 Miles from home in the Country at night and no Garages in sight or open. I did find my Doran Sensor OK but it was damaged from being flung to the road. I tried limping at slow speed but it was hopeless, then remembered my Goldwing actually run fairly well at high speed till I come to a stop. So I took a chance and goosed it to a higher speed only to find that I could actually ride it at 60MPH all the way Home. Replaced the Valve Stem with a Metal Valve Stem from Doran on both front and rear rims -- aired up the front Tire to end up with 20,000 Miles before I replaced it.
The G709 Tire is 130/70-18 very close to the OEM Tire size for the ST1300 120/70-18 and the G709 just never cups like all the other front tires seem do that I have tried. Unless someone beats me to it I will be trying the G709 as my next Tire on my ST1300. Side Note: I only run the G709 with 34 PSI as I needed to make the Contact Patch wider since it has stiff side walls it actually grips better in corners then it does with Goldwing recommended higher pressures. I our discussions on the Goldwing Darkside Board other Riders have confirmed this finding. PS: with the wider Contact Patch there is increased mileage before needing replacement.
I like the G709 so much and being scared that they might stop producing it that I actually have (9) of them at my Home coated with Armor All to stop aging in my Dry Basement. My Goldwing has over 100,000 and as a New G709 on the front presently
PS: The GoodYear TripleTred Pictures in my Gallery has 15,000 Miles on it already and looks almost new! Also note the length of the Contact patch on the Ground looking at it sideways at 34 PSI.
