I had a portable sml compressor (good for horsebox and mower) inflated horsebox tyres to 35, thought they were too hard, checked at garage, that said 48psi...
Then used a draper pen type, that said 30...
So then went out and bought a decent gauge (£35) and that said 42...
Then let them down to 35 on the decent gauge, now i reckon they are too soft...
Which gauge to believe????
So no i don't think you can say a specific pressure as you never quite know how much you got....
Much easier with mountain bike- too much no grip = pain Too little no grip = pain |

As for most members running at 30, that has to be a pure guess on your part, there's 12,000 members and about 1000 regular posters (at a guess)

Come on Andrew, that's an absolute exaggeration
there's less than 100 regular posters, probably less than 50 in reality
old members don't get deleted off the memberlist, there's still folk on there from day 1 (9 Oct 2002) that are long gone
read through the tyre pressure threads, the majority of posters say they run @ 30psi |

but isnt it true that you have to change tyre pressures according to load and amount of passengers. |
Correct, on some cars the manufacturer lists pressures for heavy loads and another for mostly traveling at higher speeds.
If you were to stick with what manufacturers recommended on every occassion you'd spend half your time driving, and the rest jumping between diesel and air pumps.
I consider what the manufacturer recommends a guideline, because if your on sand you drop pressures below what they say to increase footprint, in rocks you put more in to save your sidewalls being punctured but even the boffins cant be ar5ed http://www.carbibles.com/tyre_bible.html |

the manaufacturers have to give out some figure.. its not an absolute just a good all round safe kinda bet figure..
to be really acurate they would have to give a figure and a temperature.. u can be as an-l as u like about tyre pressures but they have to be a fair way out before any harm will come of it..

Yeah pressure and temp are more closely related than most people think...
Any given fixed volume will change by 0.6bar per degree... |
