And that has jogged my memory. I recall reading somewhere that the lower number is used for dual axles as a kind of safety factor and is intended to limit the overall load on the double axle so in the case of one tyre failing the other tyre can still support the load. Not sure of the safety factor.

I have been going back and forth on this myself. I read one article that commercial vehicles in general have the 2 figures. I read one article that the first number is single, second is dual axle. Having said that I dropped into a couple of tyre shops and both gave me opposite answers so will continue my research including the tyre size change as plan B.

Maybe the order does not matter but the lower number always refers to dual axle??

I think I will base my search on that, unfortunately that really narrows the 7.5r16 options. Maybe ill just order the Michelin zxl’s. It seems choices are mud or tarmac nothing in the AT range.

7.50x16, 235/85R16, 265/75R16 you will find have the same rolling diameter, so the ancient old 7.50x16 is no taller, just skinny.

I run 265/75R16 Yokohamma Geolander on my Dad's 130 and have done for years, just not on the std 130 wheels as they are too skinny.

A 235/75R16 will fit fine, be better on and off road there really is no comparison.

And further to what DazzaTD5 said, you will be able to source 235/85/r16 a lot easier than 7.50x16
