re: What size tires y’all fellers have on leveled F-150?

Definitely seen some baws at MudFest on 20's hitting the gumbo mud. While it may not be as good as an 18 or smaller, it can certainly be done. For mud at least.

Go as wide as you can. I just swapped my stock 20s on my 17 250 and went with the same size in the KO2. The physical tire is the same width as the stock ones, sidewall to sidewall, but the tread is not as wide. I should have gone wider. Doesn’t look bad, but would look better if they were about an inch or two wider in the tread.
