I'm sure this will have been discussed before but couldn't find it. I need to replace the tyres on my 2012 Elddis Avante 554. At present it has 175/75 R 14 C 99/98 tyres fitted and the original spec was for 175 R 14 99. Having problems sourcing tyres at
these sizes and have been told I can go to a 185  or change to a 175/70. Can anybody confirm or suggest what sizes I can fit in terms I can understand?

    Etyres (they come to you) list 175/75/R14 99T Bridgestone Duravis R630 at £87.50 each. Don't know if that's any help.

    You need to take note of load ratings more than a slight change in size. 70% or 75% of 175mm or 185mm won't make a difference to your caravan. The only concern might be the distnce from the tyre tread to a mover roller if fitted.

    Phil - out of interest, do you have a mover fitted?

    I too have been looking into replacment tyres for a while now.

    Ours came with 175 R14 C 99 - which I understand have a profile of 80 (although it doesn't say on them).

    This gives an overall diameter of 636mm

    If I change to 185/80 R14 they have an overall diameter of 652mm which would interfere with the mover.

    If I change to 185/75 R14 they have an overall diameter of 634mm - which shouldn't be a problem with the mover. Trouble is, this isn't a very common size and could be difficult to find a replacment in an 'emergency'.

    The reason I want to change to the 185 width is that they have a load rating of 102 (850kg) rather than the 175 wide rating of 99 (775kg). I think that the loading of 2x775 = 1550kg is too tight for our 1500kg caravan.

    Trouble is, am I right in thinking that the profile of my existing tyres is 80?? This could affect the whole size calculations.

    Yes Ian ..... you're right. Unless it says different a tyre is 80% profile

    It shshouldn't be too hard to adjust your mover if needed

    80% is a nominal value, it depends on the maker and tyre size it varies but is usually closer to 82%.

    Well, the last time I adjusted it there were a lot of sore knuckles and expletives!

    I think I'll measure the gap and see how much room I've got to play with.
