Is it ok to use a solid rubber tyre for my tail dolly wheel, or do I risk

That said, I think a solid rubber tyre is fine *provided that* the dolly is off the ground when the glider is being towed by a vehicle, i.e. the weight of the dolly and rear end of the glider is carried by the tow ball. The dollies for both gliders I've owned have been lifted off the ground when the tow bar is attached to a vehicle. With this arrangement the only time you'll move the glider on the dolly when is when the towbar is detached and you're moving the glider slowly by hand, so having a solid tyre is no problem. The type of dolly that rolls along the ground when being towed by a vehicle may benefit from having a larger wheel with a pneumatic type fitted, but I have no experience of using this type. -- Martin | martin at Gregorie | gregorie dot org |

If you're in USA, I suggest a "flat proof" wheel from Tractor supply. Easiest to see what will work if you take your tail dolly into the store. TSC carry a few. The tire of the one I used JUST fits inside the yoke but may not fit every caster. In my case the axle diameter of the caster was smaller than the wheel required, so I added brass bushings from True Value Hardware to enlarge the axle plus another bushing to give the correct offest. TSC Part number 3553230 Lasted 3+ years so far. Has a little shock absorption, not as much as a pneumatic but way more than a solid caster wheel. Jim |

https://www.tractorsupply.com/tsc/pr...nd-truck-wheel is what I replaced mine with after the previous (same one) being shredded to pieces after landing with it on. There's a lesson there about hurried take-offs... |

My recently delivered IMI tail dolly has the optional larger than usual foam filled tyre and also suspension to reduce the bouncing around of the glider on tow out. Its not on the website yet for some reason. |

A direct Blickle replacement wheel/tire can be purchased at http://www.magnusinc.com/ . Their part number is VW 202/20R. Contact customer service for assistance. A couple of years ago, cost was just under $40, not including shipping. It takes a couple of weeks for the product to ship. |

Thanks Craig. Bickle describe that as 'soft rubber'. It looks just like the Chinese one I had before, which, despite being solid, managed to go flat under the tail of my Ventus. The ASH 31 is supplied with a hard rubber Blickle tire for the tail dolly. = A direct Blickle replacement wheel/tire can be purchased at http://www.mag= nusinc.com/ . Their part number is VW 202/20R.

The Grob 103 in our club has a solid tail wheel dolly. Pretty heavy airplane so it shouldn’t be a problem.
I don’t get the comments about towing behind a car. My ASW-19 & 20 both lift the tail dolly wheel off the ground when I tow them. |
