Rough Country Lift.

[308Starr]

I just ordered a Rough Country Lift for my 2020 Expedition Max FX-4 Limited. I want to use the stock 18” rims. I was wondering what the biggest size tire I could install with any other modifications. Not to be sitting on my pity pot I just got out of the hospital and prior to that was getting chemo for 6 months. I have been waiting awhile to do this and don’t want any last minute surprises, I’ve had enough of those in the past year. Any help would be appreciated. Thanks in advance
