Water ballasting is common practice in increasing grip on agricultural vehicle tyres. They have special valves and normally antifreeze is added for obvious reasons.

Why you would want to add weight to an aircraft tyre may not be obvious but that doesn’t mean it is incorrect.

i agree ive just related the story as told to me i cant prove or disprove ,thats why i posted the thread ,thanks for the response

water ballasted tyres? Surely someone is pulling your leg… I can’t see any advantage to ballasting tyres in this way at all, unless someone want to shed some light on it. aircraft tyres are balanced at manufacture, and marked with a ‘heavy spot’ on the sidewall. On fitment to the wheel assy, the tyre heavy spot is lined up appropriate to the wheel’s balance. The tyre is then filled with Nitrogen. (Less expansion with altitude, but mainly used since it is an inert gas). Water does not feature in the process. I can only speak for modern (post war) tyres, but I can’t imagine the balancing process has changed much since before the war…

As said, Dunlop were (and are) a major supplier of aircraft tyres.

If I’m talking c**p, please tell me….:D

i collected some very large spoked aircraft wheels/tyres(6ft plus from up the dales (where i cant remember) however they were fully inflated when collected and the gentleman pointed out these had come from a large pre war biplane used as a target tug by the navy and the tyres had to be ballasted .:cool:

Martin Baker EJECTION seats were fitted with an initiator cartridge and one or more secondary cartridges. The number of secondary cartridges was increased depending on the height of the tail.

Twenty years ago people were saying the same thing about BMW drivers…:D

(the comments were usually made by people who couldn’t afford BMWs…or people on an anti-yuppie rant).

PS..I don’t have a BMW or 4×4…(other than a vintage open Jeep I’m restoring..currently not running, so I get great mileage).

i restore classic cars, i also like willys jeeps which i assume yours is,i have no interest in 4x4s of today because.

2 i dont regularly tow vehicles
3. i liketo wash my vehicles without having to resort to a stepladder when washing the roofline.:cool: 😎 😎
