what air pressure you run

what air pressure you run
just curious to know what people are running in there tyres and on what sort of rubber......
i just fitted cooper st on my 80 series and run 40 psi for round town, feels like it rides hard so might drop it down

Don't know if this works or not but the best way I was told to find the best tyre pressure for you car and load was to pump you tyre up to what you want then get a piece of chaulk, draw a line across you tyre tread ,then drive it a little bit ,check the chaulk line,no line in the middle to much pressure,no line on the outsides to little pressure,no line about right, haven't tried it myself yet but an old tyre guy told me this one reckons it works
White SWB MAV Diesel , 2" lift, 33"tyres
&
'99 Hilux Xtra Cab, 3Lt Diesel, Turboed, 2"lift

I run about 30-32 otherwise it wears the middle out, Bridgestone Desert Duellers (the ones with the dollar sign tread), I got 90,000ks out of the last set & they are only 175 bucks each.
Don't ask me, ask them. I'm just runnin for my life myself.
Well they are all following you...
No they ain't, I'm just in front...............

that was my thought too. How are your kidneys and your teeth fillings?joeblow wrote:....geeeezzzuuuussss....hjgq wrote:31 muds 44 psi and good even wear maxxis the tyers are about 30 k old and just under 1/2 worn
4psi rule for me, so tyre pressure changes depending on what sort of load I'm carrying, type of terrain I'm driving etc.

I run my 31" MTR's at 32-36psi onroad and 14 psi offroad
I have 33"x12.5"15 MTRs and run around 38psi on road.
That is on a GU Patrol wagon.
Off road I drop them to 19-20 first and go lower depending on terrain.
Never had issues and did the same with my old 285/75R16 BFG ATs allthough they often started leaking at the beads when run on low pressures with dirt getting in between the rim and the tyre

problem with running tyres 'hard' is that it severely affects braking performance in the wet, when you install a bigger tyre than standard doesn't mean you have to go up in tyre pressures. factory settings for my vehicle are 22-26 psi, i have gone from a 28 inch tyre to a 33 so i have come down in pressure taking into account vehicle weight and braking performance. it now runs 18psi on road and 10psi offroad. alot of tyres with heavy construction can actually support a vehicle without having to up the tyre pressuresfrom factory.Toli wrote:I run 40 psi in my 32inch BFG muddies. However I do like a hard tyre and most of the driving is to work on a freeway. Might try the chalk idea and see how it goes.

Factory pressures are typically oriented more to a smooth ride than load carrying, fuel economy or tyre life. I use the 4psi rule, and typically run tyre pressures higher than the factory recommendation.
i'm 1700 kg's loaded, but that was an example of the % tyre increase on my vehicle. just saying there are many factors involved with working out tyre pressures for cars with non-standard tyres, but at the end of the day it should be braking performance that comes first. so many tyres are constructed differently. eg- you could get away with running less air in a 35 cooper than you could in a 35 silverstone-different construction, different calculations.

they are BFG Muds they do not handle well in the wet anyway. I run the higher pressure also due to the weight in the back with the long range tank, draws, cargo cage. I am not getting any uneven wear at the moment but will adjust them to try and see how they go.joeblow wrote:problem with running tyres 'hard' is that it severely affects braking performance in the wet, when you install a bigger tyre than standard doesn't mean you have to go up in tyre pressures. factory settings for my vehicle are 22-26 psi, i have gone from a 28 inch tyre to a 33 so i have come down in pressure taking into account vehicle weight and braking performance. it now runs 18psi on road and 10psi offroad. alot of tyres with heavy construction can actually support a vehicle without having to up the tyre pressuresfrom factory.Toli wrote:I run 40 psi in my 32inch BFG muddies.

The tyres wear well. my teeth and kidneys are fine thanks for the concern LOL the main reason is to try and keep the outer tread blocks as square as pos for when off road. when I'm playing in the bush down to 20-25 no probs as I said nice even wear on the tyres rotate about every 10k - 15kJeeps wrote:indeedbogged wrote:x failteengrimbo wrote:that was my thought too.
