I don't think that "chalk test" is the best solution. You would have to drive around and around the centre court of the filling station to test it, going back far too many times.

If it was raining you wouldn't have any luck what-so-ever.

Either buy a compressor for home or do it in the dry ;)

We run roughly what the book says, a bit extra if loaded.

How many folks on here change the tyre pressure, every time they are carrying a greater load than normal? Or when they are towing?

Be honest now..:rolleyes:

I tow a caravan regularly. As said, I have 36psi all round (checked weekly)

I have never had irregular tyre wear.
 
I do change the tyre pressures when I towing, because the load is often 2+tons.

It takes me 2 mins to do as I have a compresseur at home.

I also have a compressor at home Dave. But when I get to the caravan site and unhitch, and then use the Disco for a few days, I aint goin to arse around letting a few psi out the back tyres, and then put more in when it comes the time to hitch and de-pitch. I'm not knocking anyone who does that though. Each to there own.

Just noticed...is that French for compressor..:)
 
Why would I buy an air compressor when I can use the air for free at the garage, I run 32 at front 35 at the back, never had a problem.

Free.....Free where. Cant remember last I seen free air in our garage forecourts. 50p in some. 20p in most. And you need to be bloody quick about it if you are doing more than one tyre.

Old owners hand books and modern tyres :rolleyes: I go with what the tyre makers says in the info box on the tyre, and also keeping a close eye on thyre wear, and rotate tyres 6-10k miles. If you put a higher rated tyre (load range) than what was original, Puts the hand book info nor worth a hill of beans
 
wots that then for a Disco 2?

Well depends as to what tyre. What we have here are P tyres for passenger vehicles Which any of the land rovers will fall into. Which are basically a load rage B 2pyl,2ply tyre. Then you have LT tyres which are a loaded range from C,D,E range tyre, with these they have more plys in the construction and are a stronger tyre (heavier load rating) which require slightly more are for proper inflation, and even tyre wear.

A P rated tyre will require less air and be a smother riding tyre, with less load and towing capacity.

A C rated tyre will require more air and have a more firmer ride, But will have a higher load and towing rating capicity

Both are made in the same size and tread patterns in most cases, But with slightly different.info in the box on the tyre. That is why I have always said use the info box on the tyre. I manfacture of the vehicle has no idea what tyre you are using and are just a guide line to use, other than if you got factory originals on

so wots the pressure for a disco2? ;)
 
We take a compressor with us when we are abroad with the big trailer, 8 wheels (6 + 2 spares) on the trailer and 5 on the Discovery.

We have a 12V socket on the side of the trailer running from the winch battery:

That and the extension lead means we can reach all the tyres when hooked up, and don't need to squeeze onto a forecourt air pump with 13 metres of Disco &trailer.

36 all time front and rear, with an ifor on + 3 ton of aggregate or a mini digger, maybe 6 bags of Asda shopping, or even 1 Golden lab! no uneven tyre wear on all, if tyres getting low, get new ones, then put 36 back in!:D

+1......Hallelujah. Another voice of reason:D

Bastid :p put your specs on and have a look. at a guess if It had LT AT3 like cooper then 36psi would be a start and if towing a caravan 40psi on the rear. to stop side wall flex and reduce tyre heat. and if towing a horse trailer with 2 horses 42psi rear

Or you could hitch your trailer up, with the horses in it. Apply some chalk to the tyres, and drive up the road for 100ft. Stop, get out and check chalk wear. Decide what method you are going to use to get some more air in the tyre (the choice is yours). Drive up the road again, for another 100ft. Stop, get out and repeat process until the optimum tyre pressure is found. Remember and write it down somewhere, or you will have to repeat the whole process when journeying to your next Rodeo, or cattle drive.

Ya right like fook I would. Look how tyre sits drive it and see if you got any side swaying then check if tyre temps are excessive, clear indicator of low air. Also need to check trailer tyres also/ Funny as hell This summer had my daughter for 2 weeks and met up with her mom (ex) on a horse camping week trip up north. Met at the gas station as they were getting fuel and got daughter stuff put into the pick up and was looking at horse trailer and tyre look low and was rather warm. Mentioned it to the EX and said it should be good, well after another 75 miles the tyre blew up, exploded:lol: Daughter called and said mom had a flat, told daughter tell her mom she should of listened:D
