Aftermarket tires and rims

I just bought a 2018 Tacoma TRD Off Road 4x4 with stock 265/70/16 tires and rims. I am wanting to upgrade to 285/55/20 but need some help. I have searched the internet and can not find the info I need. Is this size doable without any modifications to the stock suspension? I do not want to have to cut or trim anything either. I am not wanting a lift kit (due to money) but have considered a leveling kit. Any advice would be appreciated because I've never put after market rims or lifts on a vehicle and don't really understand all the terminology. Thanks for any help.
