I thought the same but went with the 265/70/17 last week and have 250 miles on it already and NO ISSUES or rubbing at all...no changes needed...it works and looks great. I went with the Hankook Dynapro AT2 and they have a rebate and they are ride better than the stock tires.
I got these from runningboard wareshouse and really like them, here is the link https://runningboardwarehouse.com/p/ionic-pro-series-4-black-nerf-bars/v/ford/ranger/2019/
Finally got a new setup and went with the Hankook Dynapro AT2 In 265/70/17 and it looks so much better personally and rides great with the first 150 miles. Seems more stable than stock 255/65 and no road noise with these
I want to upgrade my stock tires 255/65/17 and have the XLT 4X4 and have only done the 2inch front level kit. Is it best to do 255/70/17 or will the 265/70/17 work without any needed modifications? thanks for suggestions...the stock tires look so small....
