Something to add, I just looked at the factory spare and it is 17”. So I’m hopeful the ZR2 wheels will fit! My only worry is the crunch crunch crunch I may hear when the air suspension lowers
The 285/70/17’s are the same height as the 275/50/22, just 10mm wider. I dont think you’re gonna hear any crunching.

Put them on there already! And we need pics of the colorado with the 22’s too lol

Personally I've never liked big wheels, anything over 18" just seems silly to me regardless of whether it's a truck or a car. We still have the stock Z71 20s on the Suburban purely because the wife has an emotional attachment to keeping the truck as stock as possible otherwise I would have gone with 17s ages ago. IMHO 17s look great on everything when wrapped in mud tires

If your Suburban's front brakes are 4piston calipers, it's likely impossible to use 17" wheels.
Commenting SPECIFICALLY on your wife's 'emotional' attachment to 'keeping it as stock as possible',
you may find it helpful and liberating to disabuse her of her confining and limited notion of 'stock',
by expanding her definition of what GM OE means. For example, 265/65R18 is an alternate GM OE tire size,
and although 18" wheels are not 'cheap', selling the 20" wheels should help defray that cost,
and since the 18" tires would be cheaper in the long run, and your suspension would last longer, you both win.

20"s are so common these days that I am not sure there is much of a price difference. I got a set of 275/50-20's installed for $832. They were an off brand but way better than the Bridgestones that were on it.

I'm THIS CLOSE to buying 17" wheels specifically because
there are well more 265/70R17 tires to choose from than 265/65R18 AND 255/70R18 COMBINED
many 265/70R17 have higher load ratings, better inclement weather abilities, or better off-road abilities than either of the 18" tires I've tried
some of the 265/70R17 have better performance in two if not all three categories
all the above AND most of the 265/70R17 are cheaper than 265/65R18 AND 255/70R18
NYC roads suck so bad, that the next time a pothole kills one of my tires, at least it'll be a 265/70R17 that is cheaper AND easier to find than either 18".

In your case you may be right, 275/70R18 or 295/65R18 might not be any cheaper than 275/60R20, but they will have more sidewall meat,
for more protection from schidty roads, your suspension and steering parts will last longer, and that beefcake-sidewall look you dig ... jus sayin ...

I wish it was that simple, basically she wants to keep it as close to what we brought home as possible. With 105k or whatever on the clock and lots of utility roads, fire roads, wine country trails, etc the shocks need to be replaced in the next few months and she's seriously balking at the idea of an aftermarket off-road setup because it would be a smidgen taller.

I don't know I run the MT Baja Boss ATs and going from a 20 to a 17 in comparable size was like $30 less per tire if I'd gone that route.

Happy wife = happy life. Just sayin'. I remember talking to a woman a few years ago in a mildly lifted Expedition. It was her truck but her husband did the mods because he thought it looked cool. "I have to get out of the truck to use the ATM" she said. "I hate that f@#$ing thing".

It's like $17 less for 18's. I don't consider that much of a difference these days. That's like 5 lunches at Culvers.....

I drive it 90% of the time but I also use it for wine tours so I suppose a 2" lift and 35s might not be a wise investment with all the drunk folks getting in and out...

Yeah I look at it as how much per tire and $17ea is $68? That's over half a tank of gas, I'll take that!

Forget about the lift, just go for bigger tires & 18" wheels ...

Increased ground clearance and traction are equal concerns, I've bashed the hell out of the supports for my side steps climbing over rocks and ridges while out exploring.
