Hello Scotty !!!! I currently have a 2016 f150 V8 and am in the process of looking at tires. I have 20” rims with BFG all terrain tires. Would I be better off with a standard all season tire, or step down to an 18” rim with a street tire and maybe improve ride comfort and fuel economy?
Do you always drive on pavement? What’s the truck’s OEM tire size?
What do you use your truck for?
What is the factory configuration?
Really depends on your use, preferences, weather, driving style, commute distance ....
Too many choices to give you one single answer. The KO2’s are probably the gold standard in an off-road focused AT tire. At the other end of the spectrum, the Michelin Defender LTX is probably the best-of-breed in the highway tires. In between, the Continental Terraincontact AT is a well-reviewed on-road focused AT. But if you drive on a lot of snow, or your budget is restricted, maybe none of those would be best.
Tire Rack puts out some pretty good research that seems reasonably unbiased. For more detailed tire reviews that are very informative (albeit just on a few select tires) take a look at the Campus Automotive YouTube channel.
As far as wheel size: It heavily depends on your intended use. If you do most driving on road, I’d probably stick with the 20s. If you downsize to 18s, it might feel squirmy to you. Sure, it’s ok to do, but the boost in comfort won’t be that great. But if you want to seriously go off road, then sure, consider 18s.
I’ve found those Goodrich KO2s are great tires. I’ve got them on my 15 F150 and have no complaints.
