I have decided that I need a spare wheel for my US built boat trailer, but am rather put off by the estimated shipping cost of $150!
The existing trailer wheels are 14" with a rim width of 5.5" and take an ST 205/75 D14 tyre. The offset, so far as I can tell from my measurements, is 1". The individual wheel maximum load is stated as 1,760lbs. Having done an internet search or two I have noticed that the LEMMERZ 5.5J 14" wheel often comes up from caravan stores at a reasonable price.
Does anybody know the offset for this wheel and whether its recommended loading is anywhere near my existing wheels? I would point out that the boat will be well below the maximum loading on this trailer - probably 700kg (1,540lbs).
Just for completeness I thought I should post the answer now that I have it. The offset (ET) for this particular wheel is 30mm. Happily that is just about right for my application.
