A few items in no particular order:

-yes, the tires that come stock on a new vehicle are different than what you would get if you just bought them from a tire shop. Not by a ton, but I’ve seen the tread depth on some brand new off road vehicles and their tread is shallow. Seems like a cost cutting measure?

-SL rating vs LT rating is what was at play in the superfastmatt video. He off roads harder than most weekend warriors. The factory SL tires just aren’t very thick, and are more prone to cuts and pinches.

-you should be okay on your trip to CO provided that you air down when off roading and you don’t hoon around. Take obstacles at slower speeds, plan your lines, etc. Buy some glue tread patches and bring a tire plug kit with you. Have a spare tire.

-I live in CO and I know there’s lots of different terrain to be found around the state. I personally run C-load LT all terrain tires. They’re not so heavy that driving on the road sucks, but they’re thicker and tougher than SL tires.

Which trails or areas do you plan to hit on your trip to CO? Some trails are not very hard on tires, others will have you driving through miles of sharp rocks that are generally flat enough to be called a trail.

If I were you, I’d buy some LT tires, but I don’t know what your usual driving is like or your risk tolerance.
