Tyre pressure for LC100

Submitted: Tuesday, Nov 02, 2004 at 09:29

GTBen

Hey Guys, have a quick question about tyre pressure. I currently run BFG AT 275/70R16 at 50 psi on the road (tyre wall states 60 psi max). Does this sounds right? Sometimes I feel they are a bit hard, what would be safe to let them down to on the road? As well as this, what am I best running on gravel? Thanks

There is really not right or wrong answer , just peoples preferences.

My feeling is that you are way to high.

I run BFG AT's on both my Patrol and Pajero , and the pressures are similar.

36 front , 38 Rear on the Patrol , and 34/36 on the PJ.

The higher pressures should provide less rolling resistence , but , the downside is , a harsher ride , and most likely , more tyre wear.

Thanks flappan. This might be a dumb question, but why have 2 psi less on the front? Does this just provide better handling? What would you lower the pressure to on gravel? Cheers

No , moreso , weight at the back.

Your trying to achieve the same rolling resistence front and back.

Pressures on Gravel. Depends. Normally , I dont change anything , but , I'm not often doing large amounts of long distance gravel work.

If it was several hundred K's , or corrigations , I would be dropping to about 25/28 psi , which is the same I use on Fire Trails.

I dont know whether my method is the best , but it works for me , and I based mine on other folks experiences.

Its really about trial and error.

There should be a tyre placard some where on the vehicle that advises the correct tyre pressures. Try these and see how they feel then adjust accordingly.
IE run the vehicle for about 100k then check the pressures and if they only rise by no more than 6psi then you are ok.
This is a short summaty from the N.R.M.A. web site.

Try searching the archives, theres a thread or thousand on tire pressures in there.

BTW 50psi would be like driving on rims without tires

GTBen,
I think 50psi is a bit high. I only run 38psi front and back on the diesel 80 Series and the diesel 75 Series.
If you are still not sure what pressure to run you could use the 4psi rule.
1. Inflate your tyres when cold to say 38 psi all round
2. Go for a run at 80-100klh for about 20 minto heat the tyres up
3. Stop the vehicle and check the tyre pressure as quick as possible.
If the tyre pressure has gone up by 4psi that means the tyre pressure is correct for the tyres and the weight of the vehicle. If the pressure goes up by more than 4psi that means that the tyres are too low and creating too much heat. If the pressure does not go up by 4psi than the tyre pressure is too high.
A good tyre pressure gauge is also a must, I have found that the dial type are far better than the pen type gauges.

Hi GTBen , I agree with truckster, 50psi is way too high and on a gravel road it would skate everywhere . I have always run less pressure in the back unless I have a load on in which case I up the pressure to suit that load .
I have found that the centre of the tread is too prone to wear with high rear wheel pressure . With a diesel (or big 6) the weight proportion is 60 or 70% on the front with no load and I run around 35-36 (front ) and 30- 32 (rear ) I stress with no load , chuck 500 Kg in the back and the rear would go up to 35 -36.
There are a million opinions on tyre pressure and be prepared to change to suit the load and terrain .

Cheers Dave L Qld.

I have just put new BFG's on my lc100 and have run 200kpa in the front with 220kpa in the rear. I have now covered 8000ks by towing van to Atherton and then to the tip of the cape and stops in between and then back to Gladstone. I did not change the pressure for the corrigations or the rocks or creek crossings. The slight pressure difference between front to rear is because of load at rear but is also from my early days of driving a HD holden on the Perille radials when they first were introduced to Australia ( 1965 ). The tyres came from the fitters with 280, 240. which was too harsh so I settled for the above. I find it gives comfortable driving on the black and seemed to handle the dirt well - in fact I thought the cape gravel roads to be very good. The tyres appear to be wearing very well with those pressures.
