    Default Bigger tyre on 16 inch spare wheel

    Rather then fork out for another wheel rim, I'm thinking of putting a 265/70/16 tyre on my spare as the circumference and diameter are identical as my 256/60/18 as near as damnit, unlike the 245/70/16 fitted . A local (more friendly and helpful) tyre fitter said it should work ok. So much for Tyger Wheel and Tyre being helpful.

    Later on next year I might replace my 18 rims with 16 inch and fit 265/70/16 tyres all round.

    If you go for 245/75/16, the difference will be little less.....9.5mm

    OOPs I made a typo, my tyres are 265/60/18 not 256/60/18

    When I checked using your tyre reference the difference in diameter is 2,2 mm

    265/60/18 is 775.2mm

    265/70/16 is 777.4mm

    lol I had a senior moment.

    2.2 mm is nothing in the great scheme of things, so it should work out OK, as well as being over R1K cheaper per tyre compared to the 265/60/18

    Agree, should be fine as a spare until you change all to 265/70/16. Just changing my 18's on my Wildtrak to 265/75/16

    Hi Mike, I don't understand why you would have wind up unless you had the center diff lock engaged on a hard surface. What diameters are you talking about?

    The 265/70/16 should work fine with my 265/60/18.

    Its a good idea to change your 18's as 16's are a lot cheaper and easier to find.

    But yes, 16's are far cheaper than the 18's

    I was quoted just under R2 thousand for the 265/70/16, compared to over R3 thousand 5 hundred for the 18 inchers. My tyres are now at 20000 kms with a load of tread left, I wont even consider changing over until they are well worn. Even then I can hopefully sell off my 18 inch rims to offset the cost of new 16 inch rims and tyres.
