difference with GU wheels for 2nd spare

The only difference is the shape of the holes that allow ventilation and lighten the wheel. These on the older wheels have sharper corners and tend to crack in the rough stuff. That is one reason it is difficult to get Patrol steel wheels- everyone wants them.

Depends on your model , the petrol 4800 has bigger diameter brakes and won't even take 16 inch wheels off some other gu's .

I use spacers to solve this problem , but I'd would check it out on the car as even early gu's had bigger brakes than Gq which allowed them to move away from 15 wheels.
You can often pick up 6inch width early Trak11 toyota wheels really cheap , these have more offset than Nissan factory wheels

Hi Si
we've got the later model GU Patrol, with the current 17" alloy rims. We purchased 6 BF Goodriches, and a 17" steel standard white 4wd rim as a 6th spare. The rim cost us about $200 from our local Beaurepaires store.

The tyres themselves are not exactly to specs, but within allowable range. Slightly wider than the originals, which meant the spare on the back door did rub through the paint, until we put spacers on the studs.

We've had cause to use the 6th spare, with no dramas, but we did rotate all the tyres around (and the patched tyre onto the 6th spare) once we got home.

As we are planning on doing some camping and travelling through extreme country, we're looking at putting a rear bumper/dual wheel carrier on the back, as we're concerned of the damage that may be caused to the back door if one of the spares remains secured to it.

Hope this helps
