I have (2) brand new 20x8.5 with +42 offset and (2) 20x10 +20 offset for a Vette. The tires are 295/25/20 rear and 245/30/20 front. I would like to fit them on my 94 Z28 project. What do I need to do to get them fit.

Thanx for the help!

 

Anybody?

 

The 20 x 8.5 +42 offset will bolt right up . The 20 x 10's won't fit, not with a +20 offset,there going to stick-out to far!

 

So it will stick out 3/4 of an inch or will it be more?

 

Less, but there would still be an issue with tires and fender lips becoming kissing-cousins.

 

I've never seen a 20mm offset for a rear corvette wheel...

 

My bad, just looked at the boxes, both are 42 off-set. Will these bolt up without need of spacers or any mods.

 

I think with a 42 offset you will be ok. My fronts are 46 and they look fine. My back was 65 and I needed a 1/4" spacer and longer studs.
I would also imagine with the really low profile tire it will almost be the same diameter of the old tire and rim so I dont think it will rub. Bolt them up and give a look.
