Tyre pressures

[helen&tony]

Hi Kirsty
I remember you saying that you had some ...i just used trial and error on the tyres until I found what suits...i even think the front might be a little high??...regarding compressor....I'm just lazy, and like gadgets ....PLUS it's good for blowing up tyres and airbeds....and maybe for the odd on-site jacuzzi
Cheers

Hi dandemann
What system did you use?...

Hi Helen scroll down this link you will see two, one for standard and one for lowered.

Real easy to fit, about two hours roughly

Hope this helps

I fancy fitting these. But 2hrs? Is it really that quick and easy, even for an ageing numpty like me?

Depends how you do it, I dropped my suspension & gave it all a good clean & wax oil on the bits that are usually out of sight while I was at it, probably wasn't any more than 3 hours or so with teabreaks & fannying about with different options for runnning the air hose. I think BongoTerry here - http://www.igmaynard.co.uk/bongo/forum/ ... 72#p444472 didn't take long from what he said when I was chatting at Softies & his right arm is pretty much fubar after a bike smash. As he says in his post, if he can do it, anyone can Challenge laid down Mike, I'll expect it to be done & ready for inspection at Stourport

but I may just give it a go (got some other toys to fit also and a freshly dented rear bumper to mend so plenty for me to 'not get round to doing ' )

But the handbook states front 2wd: 1.8 bar (24psi); front 4wd: 2.0 bar (29psi); and rear (both) 2.4 bar (35psi).
So what is one to do?

Simple,one could sling the handbook or do what it says,I think the vehicle manufacturers should know what the tyre pressure should be.They spend millions on development.

Yes indeed, that's what I thought and that's what I've been doing, then I read all these posts about running pressures in the high 30's and into the 40's and thought maybe there was some other authority that I wasn't aware of. I tried running higher pressures and it was like sitting on a roller-skate - and here in Kent where there appears to be more pothole than road these days, a bit of sidewall compliance is very welcome I can tell you!

I think it is a little of try and re-try until the car feels right and settled then keep an eye on tyres for wear or uneven wear. I started at 40 psi all round and i`m currently at 38 all round back feels ok front still feels a bit hard so for the next week i`m going to try 36 fronts and leave the back at 38. I run 225 x 55 x 17 so i would think different tyres need different pressures,cant imagine running 24psi in the fronts

Exactly,the tyres act as part of the suspension,the harder the tyres the more strain put on the rest of the suspension and drop links etc.

The tyre pressure chart is on the pillar of the drivers door.

[missfixit70]

Before I'd ever heard of Bongofury or indeed bongos, a friend got a bongo, we set the tyre pressures to those on the door plate (which meant letting a LOT of air out from where they were set at the time), tyres were practically flat, handled like sh*t. When I got my bongo, trial & error & discussions on here led me to the 38/40 that I now use on my 17's.
Apparantly (have no idea how true this is) the original Jap tyres were softer compound or sumat, top speeds over there are generally lower, not sure if that has a bearing on it. There have been endless tyre debates over the years that have caused almost as much dummy spitting as coolant issues
It's up to you basically, follow whichever train of thought makes most sense to you.

Upping the pressure to 38F & 40R has increased my fuel economy by around 2% and improved the feel of the Bongo to boot. As already said, have a go and see how it feels.

I noticed going from 32 at the back to 38 had a dramatic improvement in the handling, the van was just really soggy and rolly around corners, but 36-38 is much better... depends on the brand/type of tires you have at the back, and probably the profile too..

[Timnz]

oops that was after running the van on the motorway.. more like Front 32 - rear 34 psi when cold..!

I have tyres (Wheelquick supplied) made in Singapore... which I run 40/42 on my 17's yet the Winter 15's being Van spec tyres I run at 32/34 as the ride is much harder..... thanks to Mike snr at WQ for that suggestion...
