yes, I've read every G20 wheel and tire thread here and the rest of the internet and still confused about wheel sizes, offsets, backspacing, etc! Most fitment finders tell me there is almost nothing available and not helpful.

I have a 1994 G20.

Looking for 15x8 wheels all around. Expect to put 235/60 in front, 275/60 in the rear - BFG or Cobras. Pretty basic! Don't want to spend more than $600 if I can help it.

Is there a safe range of offset that I should stay within? I'm sure I'm overthinking it - just don't want to buy wheels online and find out they won't fit.

Thanks!

I have 15 x 8 Chevy truck rallys with 255/60 on all four corners. Fills out the wheel wells nicely.

I have some Vision Soft 8 on mine, $70 or so from Discount Tire, 15x7 I think. They fill it out fine with some 235/75-15 tires on it.

Mine (also a 94 G20) has that 4WAL ABS unit on it so I presumed I need to run the same size tires all around.

I have a 1993 G20. I put 4 15x8 wheels on the van in 2016 and Cooper tires (255x70r15) Cobra white wall's all around. Now I'm considering adding 2" spacers on the rears because the tires are inside the wheel well on a G20.

When do you plan to get 2" spacers? There's a neat G20 here with new 255/70R15 tires from 4Wheelonline installed just last month.

Never run spacers. Especially on a heavy vehicle like a full size van.

I'm speaking from experience. Been there, done that. frown
