I have a 2019 four wheel drive 1500 Silverado. It came with 22 inch wheels, and 275/50-22 tires. I’m considering switching to 18 inch wheels, (long story). According to Tire Rack, the 275/50-22 has a diameter of 32.9 inches. The OEM 18s are 265/65R18, which have a diameter of 31.5 inches. They show a size of 265/70R18 (non OEM) of being 32.6 inches diameter, (very close to the OEM 22s. If I make the switch, should I use the 265/70R18? Or, am I over thinking this, and use the OEM sized 18s even though they have a smaller diameter than my 22s?
Thanks in advance for any input.
