Curious what upgrade rims to ask for

I am a new Tundra owner, I bought a 2017 SR5 w/ plain old white factory rims with the little plastic decorative Toyota symbol caps. It does not have a lift. I want to keep using the perfectly fine tires, which are 275/65 R18s. I don't want to add fender flares and I don't want the tires to rub when I turn. I don't want the tires to stick out much beyond the wheel wells, maybe a 1/2" at most. I do want nice looking black rims.

A locally owned tire store quoted me Fuel Vector's 18x9 w/ +20mm offset.

I am reading that that much offset without a lift may mean the tire will rub when turned?
What wheel width and offset would you recommend with the criteria I listed?

Also, the local tire store quoted me $375 per wheel + mount and balance and new TPMS sensors for total install of $1848. This is in Anchorage Alaska, so maybe that is a reasonable cost.

Tire Rack charges a lot less for a similar wheel, but it also costs almost $300 to ship (4) wheels up here. I assume the local stores $375 per wheel includes their shipping costs, but it still seems steep. I don't want to order from Tire Rack and find they don't work and have to deal with returning them or eating the cost.

 

$375; per wheel is the average cost of a Fuel wheel. I just put Fuel wheels on mine 2 weeks ago and they were $365 just for the cost of each wheel.
