    Default Caravan Spare Wheel - Advice Please

    I have been caravanning for many, many years with both on and off road caravans.
    In all these years I've never had a puncture in any of my caravans tyres (of course, it does happen).
    I've bought a new caravan and I want advice as to whether the spare wheel from car can be used to replace a wheel on my caravan should I get a puncture.

    Caravan 31x10.50R15 tyre on a steel rim with a PCD of 140mm
    Car - 265x60R18 tyre, mag, PCD 139.7mm

    The tyre diameters, width and circumference are, for all practical purposes, the same.
    The sidewall heights are obviously different.

    My question is, can you/is it advisable to fit a wheel rim with a PCD of 139.7mm onto studs with a PDC of 140mm?
    If you make a noise or need music in the bush or on the beach, you’re missing the point.

    Try one before you go any further down this road. My Prado and my Toyota bakkie have exactly the same size tyre and rim but the Prado wheels will not fit onto the bakkies hubs. Collar on the hub of the bakkie.

    Due to different off sets between car and caravan one can try as the previous post. Some years ago road caravans needed a bigger hole for the hub than was the case for cars. One small car like the Nissan 1200 with drum brakes needed a big hole.
    Also make sure about the load rating.

    Sorted.

    My Fortuner has 18" (PCD 139.7mm) mag rims fitted with 265x60R18 tyres.
    These wheels fit perfectly on my Sprite Tourer SP caravan that has 15" (PCD 140mm) steel rims fitted with 31x10.50R15 tyres.

    So - no spare wheel needed for the caravan.
    That's 30kg off the nose weight and bags of extra space for packing bits and pieces.

    The 139.6 and 140 are the same dimensions - the 139.6 is just rounded up to 140. Only other considerations are the bolt countersunk taper - i.e. the Amarok is round (ball taper), and the rim offsets (for which a spacer can be used as shown in previous post.)

    The shape of the countersunk of the nuts of the car and the caravan look the same.

    The rim offset of the Fortuner is 30mm.
    I can't find an ET figure for the 15" steel rim but when the Fortuner wheel is fitted to the caravan the wheel looks as if it's in the same position as the original.
