I've been looking at rims and tyre combinations. I was running 32s on allied beadlocks which are working great, but we've found another 100 horsepower so I want to sell that set while they are still good and go up to 35s. It's not huge power but I want to make the most of what we have and get as much to the ground as possible.
I assume there's a good reason pretty much everything at the pointy end of the Probuggy class is running a very narrow rim pulling the sidewalls in. When looking at the 6 on 6.5" stud pattern rims by the same manufacturers they start at 8 inches wide. They simply don't make the same sizes in the 6 stud for some reason.
Why aren't prople running narrow rims on 4wds? is it a bad idea or is it that nobody can be bothered making something fit?

Thanks Safeco, I was thinking of making hub adapters but I've looked into it and the centre bore of the rim at 6.3 inches will foul on the 6.5 inch PCD of the stud pattern so it's not as simple as I first thought, the front is straight forward but the rear will be tricky without increasing offset by much. What rim and tyre size combination are you running? 16 inch is my minimum rim height because of the brakes.

We ended up counter sinking the bolt heads into an aliminium plate then cap nuts(pajero hubs). it did increace the offset but we did the same all round and have found the steering to be the much the same. If you are looking for somebody to help you out Rolley Dixon did mine. he may be worth a call.
thanks we should be right with the machining, Brake Fabricators WA has all the gear needed. On the front I have bolts pointing outward which hold the rotors onto the hubs at a slightly smaller PCD which should clear. The rear may require a redrill so we can do something similar.
So does the narrower rim do anything more than just protect the rim from rocks? I assume it would have a lot less sidewall flex-steer when cornering hard at low pressures. Also the tyre profile would be more rounded than flat which would elongate the contact patch.
I'm trying to gauge the benefits and advantage Vs the effort involved. It's all coming apart for a check and freshen up anyway.
