worries over 20 inch rims
I found a 2015 Silverado within my price range which has all the options I want, at the price I want, still under Chevy warranty …. BUT It has 20 inch rims and tires. The truck is rated to tow 9400, ...

On previous Ford, having the optional larger tires/rims, did lower my tow rating. It had 3.73, but actual tow rating of 3.55 gearing.
Frank is correct, when comparing 18" tires/wheels with higher profile tires, compared to 20" with lower profile. There is not a noticeable difference. However in my experience, it makes a difference when comparing either to the standard 17s, which will likely have an overall lower gear ratio, due to smaller diameter. Yes, if going from either large diameter tire 18 or 20, to standard 17, your speedometer would need correcting.
