I have a '22 ZL1 1LE and run 20x11 +35 with a 325/30 tire and haven't had any problems. Not sure if the ZL1 1LE wiring harness is relocated from the factory.

I'm looking for a flush no poke look in the front and rear


So far I spec'd out:


Front 9.5x20 w/+20 offset for Atturo 275/35/20



Rear 11x20 w/+40 offset for Atturo 315/30/20.


Question is, do 315/30's fully clear the wiring harness with the normal +43 ?, if not, would the +40 clear it? Is there any poke with 315/+43 ?



In the front I was planning on a 9.5"+20 rim with 275/35's, but I'm worried about poke. The online calculator shows 1/8" less poke than a 10"+23 rim with a 285. Do 285+23 rims poke, and if so approximately how much ?

As long as you are running 315/30's out back (and NOT 315/35s) you will be fine... However I would just move the harness when you are in there, takes all of about 10 minutes...

Is any possible rub issue with a 315/30 due to tire height or width? I'm just wondering if going with +40 over the +43 would help with possible clearance issues.

Nope, I'm running 305/30 on a +43 offset and no issues (that is OEM SS 1LE specs), 315's are only 3mm taller and only 5mm closer on the inside, you'll be fine (GM wouldn't cut things that close with OEM sizing)... If you were trying to jump to 335's or something, then I'd be more concerned, you are literally upsizing a single size... You'll be fine...
