Bigger tires on 2020 Rebel air suspension setup?

Last year, I bought a secondhand 2020 Rebel with just under 40k miles. It still got plenty of tread on the stock Toyo 285s but I keep wishing they were beefier. I've got a set of 18x9 -12mm Method wheels showing up next week, and I'm tempted to swap to 315/70R18 Coopers once these Toyos wear out. I've been reading about leveling spacers and links for the air suspension, but I can't find any actual, recent feedback on how the performance. Any info would be just perfect.
 
I see you're planning a common mod but the lack of long term feedback on leveling the air suspension should be a warning. Using links to trick the system into a lifted state puts constant stress on the air compressor and can lead to a very harsh ride since you're always at the top of the suspension's travel. Your CV axles will also be at a much steeper angle, which can cause premature failure of the boots and joints. Have you budgeted for aftermarket upper control arms, as you will almost certainly need them to correct the alignment geometry after altering the ride height? @Mike Ehrmantraut
 
Doable, but you'll likely need a leveling kit or adjustable air suspension links to avoid rubbing and keep the ride smooth. Your new 18x9 -12mm wheels should work fine, but check that they're compatible with the bigger tires. Using parts designed for air suspension is important to maintain proper handling and ride quality.
