    Tyre pressures

    I realize that there is no one answer to what your tyre pressure should be other than whats recomended by the manufacturer etc. I know its different for cold climates and extreme heat climates and different road and dirt track conditions etc. I have a lot of wieght on the rear due to towing a trailer so I over inflate to compensate. usually around 45 -50. On the front I put 40 as I find it copes better with outback corrugations if the tyre is a little harder at the front. Anyone else have any views on this subject?

    I go front 30 rear 38 as per the guide on the door frame, the pressures you guys are suggesting is significantly higher is that perhaps mine is a camper and yours is something different?

    I generally run about 40 in mine. The tyres are Cooper 225X15 ATRs.

    Here guys, have a read of this... :)

    Brian... you really ought to inflate the rears to at least 40 psi.. it will improve handling a lot. :cool:

    If you are running non-LT tyres, my recomendation would be 30 front and 37-40 at the rear as per the plackard, if running LT's, I'd jump the front up to 34psi and run the rears at the maximum of 44psi specified on the plackard... most true LT tyres... ie reinforced sidewalls and such blah blah... have a maximum pressure rating of at least 50 psi so 44 should not do them any harm. Never exceed the pressure rating stamped on the side of the tyre... :)

    Having differential tyre pressure is particularly important to ensure safe handling characteristics on any rear engined vehicle... whether it be a Beetle, Fiat 126, Kombi, Corvair, or Porsche 911.

    I agree with Schomee -definitley check the BMW link- one of the reasons for Kombi owners complaining about crosswinds is incorrect tyre pressures.

    Should this be tidied up and become a sticky?

    Probably... If I recall I duplicated the article in Handy Hints on the old forum after I placed it on BWM, but it has probably been lost since the move. :(

    Stickying this and maybe moving to handy hints would probably suffice tho... still contains all relevant info and then some :)

    CHeers!

    I will up the rear to 40 tomorrow. Just checked the tyres and it has Bridgestone Bison 607, 185R 14 LT. Cant take to pump up till morrow, have to wait for canopy to dry today.

    cheers brian:cool:


    SO WHAT DO YOU PUT IN THE SPARE

    Maintain 40 PSI in the spare also (or whatever your rear tyre pressures are) so it can be used on the back in the event of a rear tyre failure, and keep a pressure gauge on hand so that in the event of a blowout or puncture up front, you can simply deflate the spare to the correct front pressure if need be and drive safely. :cool:

    Cheers!

    only at the back :D

    I run around 32-34 at the front with 40 at the back and it doesnt have much of an adverse effect on handling, and is a little easier on the tyres... gets skittish tho with anything above 36 at the front.

    Very important to have uneven pressures between front and rear... you wouldnt believe the difference such a simple thing can make to drivability! :cool:

    hrm.. well i might as well pump up the rear to 40psi when im near a servo soon.
    also ran premo for the first time.. i can't say it goes harder. but it runs smoother.
    haven't tested it out over a distance yet.

    Took the tyres up to 30/40 in my 1976 Bay camper and took it for a drive in a strong wind this afternoon. Certainly fealt better though I am still amazed how much a Kombi is affected by Gusty winds. Also had the steering tightened up and wheel alignment, and balance a couple of weeks ago so that all probably helps as well. Apparently the "camber" is slightly out, though they tell me it can't be adjusted and suggested that I rotate every 10thousand to prevent this happening again, can anyone enlighten me on this?

    Did they say Front or Rear camber- Front is adjustable fairly easily.You may need a specialist alignment or suspension centre.
    Assuming you have ball joint front suspension.

    Not quite sure but I will ask, they are a pretty friendly lot. Took it to the local tyre store and when they could see I was concerned re the camber he rang "some guy" and told me no adjustment possible. Doesn't sound like german engineering hence the question on the forum.

    Hi Cammo

    ihave jusr fitted 4 new 8plys to my t25 & whether its the new soft rubber or not the thing rides so much nicer...smoothly quietly
    & I run a pretty lightly loaded van I run 35psi the front & 40psi in the rear But going on what you describe I think you are doing the right thing. The tyre wear does give you an indication after a few kms anyway Baz
