Hey guys,
I bought two new sunraysias for my troopy.
The
wheels on the car are 16 x 7 and I now have two 16 x 8 spares.
I fitted a new 16 x 8 to the left hand front and it cleared the calliper by about 0.5mm.
I fitted the other new 16 x 8 to the right hand front and it rubs on the calliper.
All
wheels, old and new, 7" and 8" are the same offset.
I went to the tyre
shop and they can't figure it out.
The same wheel touches the calliper on one side but not the other.
The only solution so far is to grind about 1mm off the calliper!!!
Any suggestions?
Cheers, Jack

In NSW and I think all of Oz wheel spacers are illegal, QLD who knows!

I'll assume that you have a 78series 5stud troopy.
The 16x7 and 16x8 should have different offset, and the same backspacing.
Can you measure the backspacing of both size
wheels for me. It is the distance from the mounting surface to the inside lip of the wheel.
I've got 16x7 Sunraysias, and they have about 105mm of backspacing.

I'm guessing your 16x8 have the IFS offset, which is why they are almost touching the caliper. Put some tyres on them, and I think you'll be wiping out the ball joint rubbers on the front, and rubbing against the leaf springs on the back.

No probs. grinding a couple of mm off the caliper. There's plenty of 'meat' there!!

Hi It hasn't had a different caliper put on one side at some stage has it?. I once used a 60 series in a 75 that fitted but was probably slightly different.

Phil, I am not sure exactly what measurement you are after, could you describe it in a bit more detail please.
I have the 75 series 6 stud troopy.
I have measured all around the caliper and mounting surface (not including the wheel) and both front sides are identical.
All
wheels are zero offset.
The tyres dont rub, just the wheel touching the calliper.
Cheers, Jack

Jack,
The above diagram shows what backspace is. If a wheel has no tyre on it, you simmply lay it down on concrete, and heasure the distance. If you have a tyer on it, lay a piece of string across the inside of the rim and measure.
Backspace needs to be the same on a particular vehicle (to prevent fouling). Offset will differ with the width of the rim - so the offset on a split rim, 7 inch and 8 inch rim will have different numbers for your troopie.
I'm guessing that the 16x8 rims have too much backspacing - I reckon they may be the ones for the 80series and Prado. The backspacing for your 75series should be about 65-80mm.
