Outer Limits 4x4 Board

I tried a mate's 15" sunraysia rim+tyre on my GU this arv and it fitted fine front and back - the gap between the rim and the brake caliper was from about 6mm min to 8mm or so max. We bolted the rim up and turned the wheel a few times to check it.

My question is, is the gap described above enough, or is there a larger minimum required or recommended? Any heating issues due to reduced airspace? (just guessing wildly)

thanks,

Sounds fine to me` But not leagl as GU came out with 16" rims
and you will end up in poo if you have a prang

ta

mine actually came with silly 17's :(
I'd probably only be running the 15's off-road anyway, and put the 17's back on during the week

cheers

All good

That's interesting .. a mate tried 15's on his 2003 model and they wouldn't fit on the rear? Wonder what the difference is? Were your 15's Nissan or Toyota offset?

Simo

toyota I suspect, but I'm not sure, I'll check in the morning

I have been told they have differant brakes between the petrol and diesel,
the higher kw petrol has the bigger brakes ?

yeah I read the same thing too, in the bible threads


further to this, my mate checked the gap bgetween the rim and brake on his GQ where we got rim off in the first place and it has about the same gap as my GQ. mine's a 3.0 TD, I guess they're too gutless to warrant bigger brakes

Must depend on state - it is legal to go to down in rim size in QLD. All that matters is the overall increase/decrease including tyre.

So, if going from 17 down to 15, all you need is the correct profile tyre and you're OK.

The rim diameter may be varied from the standard size
but the overall diameter of the tyre must not vary by
more than +15mm or -26mm. (from QLD transport)

I have 35 BFG muds on 15s no probs with fitment or heat issues they are toyota offset, also been engineered no worries

i had 15" toyota offset on my 00 GU ute, drum rear and disc front. I had no dramas.
