    I have a Fiat Ducato based Chausson which has a set of 215/70 R15 CP 109R tyres.

    Can any one clarify the significance of the R in a load rating of 109R and P in the CP speed rating?

    Would a tyre rated just 109 and C be good enough.

    R is for the construction (Radial)

    C is for the tyre use (C- commercial)

    P is the speed rating (P-93mph)

    Thanks for info

    I have had this from a tyre supplier which adds a bit more to the posts you have sent

    The CP rating is specialist camping tyres that are made only by Continental and Michelin.
