What does this button do?

Stock tire size I assume since you don’t have a lift? Those tires look big, might be the tread, what type?

Stock size 265 75 16. The pro4x comes with a 75 and the lower trims come with a 70 sidewall height. It does seem a little big compared to stock hankooks. Goodyear wrangler Duratrac E1 load rating. I recommend the c1 rated tires since they are much lighter and ride softer. I will be going with C1 rated tires next time.

On the transmission what is it when you put it in drive and slide it to the left? I’m a new P4x owner
