    Thanks Gary, I will go with the standard tyres that you suggest but must admit that I wouldn't have thought of balancing the caravan wheels although it does make sense to do so! Cheers, Andy

    Thanks for the thought Graham,
     
    I live between the Tropic of Capricorn and the Equator and afraid that until one has lived in such parts of the third-world, the mostly chaotic ways of parts of the third-world are simply beyond the imagination of first-world dwellers. Lol.
     
    Even the "postal service" will often take a few weeks to deliver letter mail from one side of town to t'other and that is in the instances where the mail does actually ever get delivered as much mail will simply disappear!
     
    Whilst I have no doubt that the import/export of goods is obviously possible for a high price and high risk, a private individual like me would never consider it without having contacts in all the right places, and timeframes incurred in such an exercise would typically be measured in many months.
     
    I've already given the idea much thought, and the only way forward that I would consider is fitting non-low-profile tyres such as 175R14s assuming I can get sufficient confirmation that clearance won't be a problem.
     
    Thanks,
    Andy

    Fitting Taller Tyres into Wheel-Arches
    Fitting Taller Tyres into Wheel-Arches
    .
    Hi,
    .
    Has anyone fitted tyres onto their caravans that are taller than the Original-Equipment tyres?
    .
    The O-E tyres on my particular caravan are an extremely rare size 185/65-R14-LI93 (OD=596mm) and like hen's teeth in the third-world where I live and I would guess that a similar situation might apply to other caravan makes.
    .
    Would anyone know whether the wheel-arches of a Series-5 Bailey Ranger 500-5 can safely accommodate full profile 175-R14-LI99 tyres (OD=634mm) or tyres with a similar Outer-Diameter to these?
    .
    I intend touring a number of different third-world states with caravan in tow, but it can be very difficult sourcing even basic things like tyres out here, certainly when compared to Europe.
    .
    And although the caravan's O-E tyres still look to be in good condition, they are 8-9 years old. So, along with getting a spare tyre, I'm seriously considering replacing the currently fitted O-E tyres with new tyres that are relatively commonly available.
    .
    But tyre-stores out here are unfamiliar with caravans and the caravan-stores that one might very occassionally find would not be familiar with European caravans, so I have to learn the appropriate knowledge to choose safe tyres from what is available.
    .
    Bailey Ranger/Pageant tyre specification is based on MTPLM :
    .
                 185/65-R14   195/70-R14
                      596mm        629mm
                 LI93=650kg   LI96=710kg
    .
    S5 Rangers     < 1300kg            -
    S6 Rangers     < 1300kg            -
    S6-Rangers            -     > 1300kg
    S5 Pageants           -     > 1300kg
    S6 Pageants           -     > 1300kg
    .
    The taller tyre size is used on three of the Bailey Series-6 Ranger single-axle models (500-5, 520-4 and 540-4) because their MTPLM increased to be > 1300kg, which suggests to me that the wheel-arch can probably accommodate tyres up to at least 629mm, as I would guess that the same wheel-arch box is likely to have been used across all single-axle caravans in the Series-5 and Series-6 caravans?
    .
    It would be so nice if manufacturers specified something like "The wheel-arch caters for a maximum tyre size of up to say 660x195mm" instead of only specifying the size of the actual O-E tyres they fit, which seem to be dictated solely by the lowest loading margins possible.
    .
    My proposed use of tyres that have a higher load-rating doesn't mean that I will overload this caravan as it's axle is only rated up to 1300kg as specified on the AL-KO axle label.
    .
    Sorry about the War-and-Peace length.

    LI = Load Index :
    .
    LI gives maximum load that may be carried by a single tyre. The following range of LI values covers the requirements for many European caravans : 92=630kg plus 20kg increments to 98=750kg plus 25kg increments to 108=1000kg.

    Tyres LOAD and INFLATION TABLES :
    .
    Where a manufacturer's recommended tyre pressure is not available, this formula will allow you to calculate the approximate tyre pressure for your caravan.
    .
    (MTPLM Kg) x (Max tyre pressure in psi) / ((Max tyre load Kg) x (Number of wheels)) = Running tyre pressure in psi
    .
    http://www.tyresafe.org/tyre-safety/caravan-tyre-safety/load-and-inflation-tables
     
    The extraordinary demands placed on tyres fitted to caravans mean that, in the interests of safety, it is prudent to avoid continuous operation at or approaching the tyres' maximum load capacity. It is recommended that the maximum vehicle load does not exceed 90% of the combined tyre load capacity as indicated by load index.
    The following tables reflect this recommendation by highlighting in red the axle loads in excess of 90% and up to the maximum permitted for the tyres. (The loads shown assume two tyres per axle).

    Hi,
    Just a quick hello to get started, it's good to be here as I need some advice which I will request in the appropriate forum.
    Thanks,
