Outer Limits 4x4 Board

G'day, had a quick look through the bible, couldn't find what I want to know, and the search button turns up no results (for anything, is it broken?)

What I want to know is what offset rims do I need for a wide track sierra (1995/hardtop), with a 2inch body lift and 2inch suspension lift.

I'd like to run 31x10.5x15, with the possibility of going to 32's later on.
Ideally it needs to not scrub/rub anywhere on the factory panels, but if I have to do some massaging with a hammer or grinder then so be it.

I have thought about 2nd hand f100 rims, but would prefer to buy new.
So if anyone out there can let me know what offset i'm after i'd be muchly greatful.

Cheers
Dan

Enter in the search "speedy AND desert AND rat" You should turn up plenty of info. These are the biggest offset rims for the zooks

F100 15x7's are ok for a NT
F100 15x8's are ok for a WT

roh trak2 15x7 -10 offset

speedy 15x7 -15

speedy 15x8 -28? i think...

with your BL and susp your only concern will be the original bumper outrigger/crossmember that you might have to chop off and rubbing on the springs.

speedy 15X7's are spot on, that's all you need to know.

PS I hate working in offset, it's misleading. both a -28 8" rim and a -15 7" rim have the effectively same backspacing (within 3mm) , and for fitting tyres on a sierra THATS what matters.

I've been told this recently too, and told to get kings over speedy's. Anyone know what offset the king 7" and 8" rims are? The speedy 8" rims only have -28 offset which is going to put the tyre in the same spot would it not considering the 8" rim is about 24mm wider than the 7" but only and extra 13mm offset. So 8" speedy would have 73.6 mm on the inside of the mounting flange and the 7" would have 73mm (half the rim width in mm then subtract the offset).

So unless there is an 8 inch rim swith more than -28 offset then I fail to see how an 8 inch rim will stop spring rub etc.

7" are -12 or -13
8" are -25

I was told this about 2 months ago, so I hope my memory is correct, I remember the Kings were only a couple of mm less than the speedys. The Kings were also about $7 or $8 more per rim from where I bought my speedies.

Thanks for the info. So the general concensus was that the speedy 15x7 (-15 offset) are the rims I'm after.

Thanks for that guys.
