tyre preasure
Hi just wondering if anyone knows what the correct tyre preasure is for my van as i have been told different ones.My tyres are 185x14.
Cheers

Re: tyre preasure
Have you checked on the drivers inner door frame, there should be a silver sticker with the correct pressures.

Re: tyre preasure
The 80-90 wiki says =
So (unusually) our wiki is not a mine of information on this subject
Haynes says :-
38 and 55 for 185R14C
33 and 42 for 185SR14 Reinforced
39 and 48 for 185SR14C 6PR
However my 88 reg van says 43 psi front and 53 psi rear on the sticker (which is what I use)
Hope that helps
e.g. Bowton Lad: My Auto-Sleeper camper is registered 1/84 (manufactured 10/83) & the VW T25 Instruction Manual dated 7/83 gives the tyre pressures for 185R14C commercial tyres as:-
FRONT: 2.5 bars (35 psi) REAR: 3.3 bars (47 psi) SPARE: 3.3 bars (47 psi).

Re: tyre preasure
"correct" tyre pressure is alway a bit of a moot point and influenced by brand, loading and driving style. as a general rule you are trading rolling resistance against grip... more pressure = smaller contact area = less resistance = better mpg but at the cost of cornering grip and, eventually, uneven tyre wear.
doesnt help that much i know, but at least it explains why you get different recommended figures. A t25 track day
might help you finesse the settings...

Re: tyre preasure
My 43 and 53 seem to work. Any less and it feels a bit soggy. I have not noticed any uneven tyre wear on the TinTop over 8 years and 2 sets of tyres (that includes the ones on it when I got it).
Not had the Hi-Top (heavier) long enough yet to comment on tyre wear, but when I bought it I drove it around for a couple of weeks before checking the pressures (I know = naughty boy). When I checked them, they were all well below my usual 43 / 53 and when I pumped them up it felt much better.

Re: tyre preasure
My Original Manual states the following
For Tyres 185 R 14C
Fronts = 2.6 bar = 37 psi
Rears = 3.8 bar = 54 psi
Spare = 3.3 bar = 46 psi
Hope that helps.

I forgot to mention that my manual is from April 1983.
It is amazing how little the manuals tell you from back then

I assume the wiki states that you must use tyres with C on the end for commercial / light van rating.

1) I would always believe Herr Volkswagen rather than a Haynes manual. However, the pressure in the spare tyre should always be equal to the highest pressure required in any tyre fitted to the vehicle. So, in the table above the spare should be at least 3.8 bars/54 psi.
2) Tyre pressures vary between air cooled & water cooled vehicles. The former seem to require higher tyre pressures, particularly the rear ones. Tyre pressures in later vans may vary ie. around 1986/87 onwards. Always check the sticker on the door pillar or manual for your van or get the tyre pressures appropriate for the year of your van.

Re: tyre preasure
Just topped mine up, front at 37psi, rear 50psi.
Will see how it goes at these pressures and possibly increase the rear tyres to 54psi in a couple of weeks.

Re: tyre preasure
Ive just chaged over from 185/14 c to 205 70 14c any thoughts on whether pressures should be the same or different to 185s. Ive got 40 front and 50 rear andvfronts feel v rsttly I.e. showing up suspension faults. Cheerd
