Thread: 35-36'' tyres legal on Series vehicles or not?

But, as Diana has said above, a military series 3 (in particular) is in almost every particular equivalent to the 1-ton which ran 9.00/16 tyres. Take advantage of the factory option 35 inch tyres and who could object? The vehicles left the factory engineered for them.

The 35s were not an option - they were standard only on the 109 One Tonners and they had a different axles setup to standard 109s - mil 109s are different again and did not have the 900/16 option as far as I know.

The Series 2a/3 Optional Equipment parts book lists wheels for 9.00x16 sand tyres for all models, as well as regular tyres for the One Ton.

If it is listed for all models then your covered for all models I would have thought

Sorry Garry, your argument concerning 1 ton axles doesn't wash, especially considering current 1 tonners have reverted back to standard Rover type diffs.
About 9 years ago I built and had a hybrid engineered on Q78s (36'') after proving to the engineer with part numbers that the equivelant size were fitted to the Shorland Armoured Car in the UK, which although weighing around 4 tons, still had the standard swivel housings,spindles, hubs and brakes.On fully floating axles these are the important components that concern the engineers, not how strong the diff/halfshaft components are.
And before anyone chimes in to say that TSL Q78s are not DOT approved, The bloke I built the hybrid for obtained sufficient technical information from Interco the tyre maker to convince the engineer otherwise.

I stand corrected.

What do you mean by current 1 tonners - (Defenders etc???) I thought we were talking about series vehicle 1 tonners I thought they have either env or sals front diffs. Were there any series 3 one tonners with rover front diffs?

According to the parts book, one tonners had the Rover diff from September 1974. The ENV was only on Series 2a; earlier Series 3 and late Series 2a had Salisbury.

Another point of note for series 2a ex militiary Aussie landies with cut away guards.
The cut away guards were done for two reasons.
1/ to improve access to the tyres to clean off mud.
2/ Improve body clearence for 900x 16 tyres.

The series 2a Aussie Military landies have taller suspension that stock just for 900x16s and I beleive the forward control 2a/b landies ran the the same chassis , or a extremely close copy of it and they run 900x 16.

In pracitice the military 2as never ran 900x16 as it was not needed for for most duties and the landies broke more than enough axle shafts with standard rubber in army drivers hands.
The fitting of 900x16 to the Aust army 2a landys was developed for the ambulance version and thing were carried though to the other versions for interchangeablity.
