I am going to test fit this combo this week with a 285 35 20 tire and a 12MM spacer and I will get back to everybody with results.

A 12mm spacer will put the inside of the wheel essentially right where the SS 1LE wheels sits. A 15mm would provide even more inner clearance, and outer edge of wheel would still sit 0.4" inward compared to a SS 1LE. My approach would be to use the minimum spacer to get the job done, but a hubcentric/wheelcentric spacer is "must have".

I'm interested in your results!

All of these wheel and spacers center on the lugs. They can be very close but a 40 thou difference on the hole size would be alot at 60 miles an hour. I have used up to a 73 hub center and no problems. You just have to tighten it correctley like one with a more tight hub. Meaning oppisite sides tight then the other lugs tight. I run it up a little and maybe just a little over hand tight then an oppisite a little tighter the back to the first one and get those 2 about 20 or so ft pds then put all the others on and tighten the first 2 to to speck then all the others. All wheels should be done that way. I have not seen a hub that is tight enough to completly cente rthe wheel even stock on stock.

Thanks for all the input. Based on what you mentioned about the height of the tire POSSIBLY being an issue, I think I will run Michelin 285 30 20 all the way around with a 12MM spacer up front with 4 2019 SS stock 20 x 9.5 wheels. That way I can rotate the tires front to back.

Eventually I will go with APEX ARC-8 wheels 19 x 10.5 ET35 all the way around with a 305 30 19 tires and a 20MM spacer on the front. Of course this also will be rotatable front to rear.

here is a 305 30 20 on a 10.5 strut clearence is way plenty with very little poke. It passes my humpey test no problem off set is 25. I feel fine going to an 11 rim with apporiate off set here as I can get near half inch between the tire and strut closes point, im talking down on the back side closes point not whats in this pic. And its about 7 mil further in from the fender than the same on the back so. I really see no need to go that short unless rim width comes into play but the 305 30 20 on a 10.5 is a brezze

295 compared to 305 with the most poke . I gotta say Im like the extra poke of the 305 because the 305 is about .8 of an inch shorter it can poke alot more with no rubbing issues. makes it look way better beefier. Like its on steriods but not in a bad way lol
