Thread: Tyre Load Rating Numbers - Defender 130 Single Cab Chassis

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.

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.

i ment to type 235/85R16 !!
