x army olypmic steeltrex 750 R 16 lt

The Army still use them Eric :)

They may not have been in storage for long at all, just may be surplus or 'old' stock.

Eric,
When tyres are made their is a waxy film put on them to slow/stop any rubber "going off" they never worry about telling you this when you buy car tyres, but go out and but a couple of bike tyres they warn you and warn you again, scuff it in before you trust it completely, when tyre rubber goes off the compund becomes harder, and the tyre doesn't tend to have as much grip, but with a little care, they should be fine.

yeah i reckon the steeltreks on our rovers put up pretty bloody well around TSV, Shoalwater etc.
they copped some abuse and I don't rememnber a lot of bitching about them so thats a good sign.
seriously mate i reckon for the right price they are no worries
cheers

Could you please let me know what the 4 lb rule is so I can try to remember to use it

Basically the rule says that for any given speed, vehicle load, tyre and type of vehicle the tyre pressure when hot should be around 4PSI more than the cold inflation pressure.
It was originally put out by Michelin I think.
After driving down the road for say 1/2 an hour (long enough for the tyres to warm up) at the speed you normally travel at check your tyre pressures.
If the increase is more than 4lb you need to increase the initial (cold)pressure in the tyre.
If the increase is less than 4lb you need to lower the initial pressure.
Changes in speed and load will cause a change in the pressure increase, with a bit of practice you will be able to find a pressure that is right for your vehicle and your travelling speed on dry roads.
Wet roads will let the tyre run cooler so the pressure increase will not be as great.
I've used this method for 30 odd years with great results, the only time I vary it slightly is when running on rocky stony roads at speed where with modern passenger/AT type tyres it is recommended to drop the pressures to lower the risk of damaging the tyres due to rocks punching through the tread. If this is done you should lower travelling speed as well as tyres don't like overheating and the 4lb rule can still be used as a guide.

I do not think they are old tyres as the tubes look ok and they perish real quick when left flat and open to air & light. I was only trying to find out if anyone had experence with them and what ply the walls would be. I have fitted them and so far am happy with them. Went to local quary and they climbed ok then did 50k highway not noisy and handled ok. will proberly do 2000k before we go away and if I have any trouble with them they will not be going but we will. thanks for the intrest truckster but that was someone else saying they might be old [like me] we didt even have these tyres when I did my time.

Must have misread someone elses reply above, thought they were old.

kewl, safe travelling !
