Our AWD QX50 has 255/45R20 (low profile 20") and I'm looking at Security Chain Company ZT735 Super Z LT Light Truck and SUV Tire Traction Chain
It actually handles pretty well in terrible conditions, just wanted to have some extra grip on ice, etc.

However(!) the owner's manual says:
Tire chains/cables should not be installed
on 255/45R20 size tires. Installation of
the tire chains/cables on 255/45R20 size
tires will cause damage to the vehicle.
page Do-it-yourself 8-35

Does anyone know why & what damage could occur?

Wow. Tell me this didn't happen to you.... yikes.
Thanks for the input and photo. Shouldn't travel at more than 20MPH with chains, but I get the proximity of the well and the brakes, etc.
Cheers - I'll post back if I find anything that looks less problematic.

That is just a stock image found online ~ not me

I'm from a Lake Effect Snow Area ~ directly at the south end of Lake Michigan

A populated area, so the State and Municipal Plows get out and clear the roads decently enough where I can get by with All Season Tires, AWD, and Experience of Winter Driving without ever using Chains.
