31inch to 33inch

Dougy,

I run 33's on mine - with the front mudflaps still on the truck.

I had to put a spacer on the rear door for the spare though, as it wouldn't fit on the normal orientation as it hit the door and the rear bar. Mine are the factory alloys so I didn't want to turn the rim around...you may be able to do this and get away with it, but I still think you will need the spacer, as it lifts the tyre up, and spaces it out from the door.

Thanks Morton, I adjusted the valve spring when I lifted my last vehicle, have got the lift kit but haven't installed it yet, but will adjust rear brakes when I fit it. Want to go for the bigger tyres mainly for sand driving

Thanks happygtu, I looked at another gu yesterday and with standard bumper u may fit 33" but I have arb rear bar on mine and the original spare nearly touches already so I will need a spacer. Do arb sell these spacers?
