Outer Limits 4x4 Board

I'm assuming stock vitara rims would narrow my track,
compared to stock Sierra rims.
I have Sierra stud pattern fitted to axle already

By how much?

No I'm not narrowing Da Frog )
I building a trailer and may need to narrow it to match the Frog width,
by a tad.

Haven't searched, even tho I know this has been well discussed. But I don't really understanf the tech terms.

Model Rim Size Offset
Sierra 15' x 5.5" 10P
Vitara 15" x 5.5" 25P
Vitara 2.0 V6 16" x 6.5" (alloy)
Grand Vitara 16" x 7" 5P
Jimny 15" x 5.5" 5P

So vitara rims will make the car 15mm narrower per side than sierra, (for the same rim width) - or about 3m narrower than your offset

25P will give you the narrowest track width of any off the shelf rim - it will measure up at about 4" backspacing (an actual 3.75" backspacing)

PS narrow tyres are all you want on a trailer so I would avoid 31s etc- it is only more rolling resistance you have to drag along. You are wise to try and match your track width though. Another option might be lj/ sierra 16" rims and tall, narrow tyres like your old SAT's.

That's going be one narrow track trailer

Well, Chris's rims do measure their backspacing the way most people measure offset

16's have crossed my mind.
See what comes up at what price.
See how width looks etc.

Smaller diameter are supposed to offer less resistance, too.
So there will be a compromise.
Don't wanna be too smaller diameter, or it won't follow well.

I'm making it up as I go along.

Yep, the buggers won't stay on the hubs without a nut or two on.
Often had them land in my lap during fitting
