Thread: 9.00 16 Tyres

Pressure is too high - remember you have a lot of tyre for a lightweight 101 so tyre pressures need to come right down when unloaded.

Along with Cooees old yellow 101 (same tyre/wheel combination) these tyres give a nice ride but are really too big for every day use.

I am in the process of buying some wheels for my 101 - they will most likely be 8" but like the old 9.00x16s I will be looking for taller narrower tyres - something like 36" but only about 11" wide - not sure what type as yet.

No - it is a maxxis thing. I have put up to 55 psi in my (non maxxis) 285s on 7" rims and they don't crown like that.

When they first came out there were pics of Maxxis on 8" rims at low pressure that were curved like bike tyres.

I'll drop em down a bit and see how it goes.

Simex 36 inch on 8 inch rims compared with the standard 900x16
They are 6 ply and should flex well when the pressures are lowered for off road work.
Interesting to note the max pressure is 40 psi.
they are tubeless radial tyre.

This is compared to the 7.50x 20 on the studebaker

I only have one tyre currently as I am doing a lay by plan with the local tyre place.
The plan is.
To only have a tyre slightly bigger in diameter than the 900x16 as not to change my current gearing as I am happy with it.
I wanted soft side wall and radial construction to improve the 101s ride and grip on road.
The centre blocks should come into play at full pressures for on road work and keep the manual steering light enough.
Drop the pressures and they should flex and the side lugs come into play for off road work.
If someone wants to get really , really smart these tyres should be with in the letter of the law ( VSI 50 ) compared with the 900x 16 fitting and thats discounting the fact the 101 was designed at the factory to take wheels up to 20 inch so it could be inchangeable with the guns it could tow and other miltiary vehicles and why the 101 landy is the only one with a 6 stud wheel pattern.
The wider wheels are exactly 1.5 inches wider than stock and also with in VSI 50

Hi Ron,

Were they the narrowest 36" you could find? They look like they will wear pretty quick on the road but will be good offroad.

The next options where bigger 37 inch tyres.....ie swamper boggers.
I did want a bit of width as I found every time I go to Stockton the bar treads dont float well over sand.
The bar treads dont wear well on tarred roads at speed and is the reason why I have to replace my current tyres which I have done about 20,000 km.
The simex should last longer....I hope twice as long so I can justify the extra cost.
I am guessing about 28 psi would be a good pressure for these tyres on road to get even wear.
My worry is if I can steer it at those pressures with the manual steering.
If the steering is too much for me I will have to run a higher pressure and wear the centre of the tyre first and then flat across which will lead to heavy steering again.
In the pics the Simex is at 40 psi...its maximum pressure and note the bar tread which has a similar curve across the tread and has worked OK.
Time will tell if it goes to plan.
The width should work for me on road and off road and stop my front wheel hub foot tread rings from getting bent.
These tyres will flex greatly with lowered pressures and follow the ground , something the bar treads didnt want to do even when pressures were down to 6 psi and the simex or infact anything else cannot be worse than a bar tread on a wet tarred road .
I will not have a full set of tyres for a while yet and this first one was to check the clearence between the tyre and the tie rod end .
It is worth noting the other bigger tyres advailible tended to be bias type tyres and I wanted the better ride and flex of the radial design.
A few local 4wds are runing these tyres and are reporting good wear .
