Standard 1LE front size is 285/30, so you're running an even bigger split in diameter than stock and have no problems. I autocross on those sizes in 19" wheel diameters in my 1LE and it also doesn't cause problems. The TCS/ABS has a wide enough tolerance range to accommodate this split.

Are the 5th gen ZL1 rims the same size as the 6th gen SS LE ?

I have the tyre calculator open
305/30/20 and 285/30/20 are 1.8% different on diameter (Stock setup) 315/30/20 and 275/35/20 are 0.7% difference 305/30/20 and 275/35/20 are 1.5% difference 315/30/20 and 285/30/20 are 2.6% difference You would be better running a 315 rear and 275 front to get the closest rolling diameter |

Since the stock 1LE tire sizes (205/30 and 285/30) are a well known quantity, it seems like a no-brainer to use those if you're willing to use 11" and 10" wheels. Another option would be a square setup with 10.5" wheels and 305/30/20 tires at all four corners. If you used wheels with identical offset and used spacers up front, you could rotate them front to rear as well. There are several threads on that setup.

After much research I pulled the trigger on 315/30 combo for the rear , did the relocate of the harness in the drivers rear wheel well and have no rubbing issues what’s so ever. Tire fits perfectly and couldn’t be happier. I stuck with the 275/35 up front and this is a 1SS and damn it rides great and looks awesome

I went with the 275/35 on the front but had to get 305 rears this time instead of the 315s I wanted. Damn convict country not having fat tyres in stock

You're correct that the 275/35/20 is taller than the 315/30/20. However as Stalker points out later in his reply, only by 0.7% and/or 0.1 inches. That's the closest match up I think you could probably get when changing to a wider, staggered setup. Quote:
True, closest rolling diameter wouldn't affect much, since we know the 1LE setup has a larger difference of 1.8%. But it does match up the look more closely in diameter, if that matters to you visually. Quote:
I don't know if most people would want a 305/30/20 on the front, unless you were going for all out poke out on those fatties! And you'd have to run at least a 325/25/20 or wider on the back, just for S & G! |

I have been trying to find this exact offset. Do you or anyone else happen to know what that ET is?

I don't, but there some threads on this forum on this very topic. If you want a truly square set, you'll be getting wheels with something like et35, and then using spacers for the front (can't recall the thickness) to subtract some of that offset. That allows full rotation. As a reference, a 1LE front wheel that is 20x10 with 285/30/20 tire has 2mm offset, but I think a 10.5 with 305 would probably need a bit less net offset - maybe 17mm?
