Downplating an axle

    So its time for a tyre change on my D-Max , and since my rear axle is plated to 2200kg I need 112 load rated tyres , which are very hard to find. This was done to plate the D-Max up to 3500kg GVW which I dont need as I only keep tools and a few other bits in the back at any time. It weighs 2030kg unladen so going from 1470kg payload to 1270kg is not going to affect me a lot.

    Id like to change the wheels / tyres but all I can find is 108 / 110 load rated tyres easily enough.

    So what I want to know is how can I get the trucks rear axle downplated to 2000kg (enabling me to use 108 load rated tyres) and be all legal about it, also what would be the ramifications if I didnt downplate and just changed the wheels anyway even though Id never get to a load that necessitated a 112 load index.

    Wasn't this a dodge done by Isuzu to dodge vrt?

    As Colm says, I reckon if you try and do this officially you could be clobbered for the difference between whatever VRT rates applied at the time.

    Will the DOE test pick up on the load rating of the tyres, does the system tell them what should be fitted?

    Another problem in the unlikely event of a serious accident is insurers using the wrong tyres as an excuse not to pay out.

    What tyres are you looking at, I'm sure BFG Goodrich do 112 rated tyres.

    Well it has bridgestone duellers on it at the moment (245/70/16) and was looking at the same, but cant find them from any site id trust. Grabber AT's or BFG's would do, just something in an AT pattern that complys and isnt chinese.

    To be fair I was more interested in changing the wheels to 18s or similar (not 22s/24s or anything mad) but that just seems to make it even harder to find tyres that comply.

    It was indeed a VRT dodge, can anyone clarify if they can get me for that for a plating modification, especially considering it meets the N1 type approval currently used for VRT'ing commercial vehicles.
