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

My Series 2a owners manual only lists 9.00x16 for the FC, but my Series 3 manual lists it as an option for all 109s. I'm pretty certain it was not an option for Series 1.

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.

Hi Wagoo

Crank the music up! they are playing the baby elephant song.

All jokes aside, large wheels are a curse, as they restrict the turning circle too much, besides that, the extra load placed on the transmission components by the increased torque from the larger wheel radius, causes breakage in a system that is normally quite strong.

But if you really need to, legally speaking I would go ahead with that, because it was a factory option. but hey, I'm only a bush lawyer.

Thanks John, I thought that was the case but I lost my optional equipment manual years ago. Seeing as only 9.00 x16 is mentioned verses an actual tyre diameter, then technically under VS150 one should be legal with say 36'' Simex ETs, as these are still under the diameter of the aforementioned Michelins.

Now that is funny,you can easily engineer 35's on a Defender in NSW,and my 35's don't inhibit my turning circle at all.Never heard a Land Rover drive line referred to as quite strong before either.
Nothing that a few extra bits doesn't fix though

Thanks Arthur but your legal qualifications are all I require I've been using tyres in that size region and had the transmission and turning circle stuff sorted out for the past 30 years.Just wanted to be reasonably certain I still have a legal leg to stand on.

My point is Wayne, that you shouldn't have to go through the hassle and expense of engineering a vehicle for a tyre size that was available as a factory option anyway.

Unfortunately the law is an ass Bill.It comes down to what the tyre placard on the vehicle says.If the vehicle is pre placard then it is per year and model fitment unfortunately not make!!!

Michelin 9.00 16 XZL are listed as the OEM in one of my FC parts manuals so anything the same diameter must be legal (with the 50mm rule in the upcoming revised VSI 50 you can go over 38"). Given that the SIII 1 Ton only had a salisbury front diff for part of production and the rest got Rover front diffs, so in effect the only difference between the 1 Ton and the military chassis SIII is the low ratio box and AKAIK that is not part of the engineering for mods.

So one has to assume that for any series 2a or 3 109 you could use your Simex, provided of course you have the same 3" wide front brake shoes.
