G4 now has 5100 miles and I want to get it rotated. Don't want to pay for new tires until it reaches 3/32.

So I'm not sure if it smart to rotate tires myself as a mechanically-inclined noob since it just rotation. I do go to garage rental shop that has lift as I had done oil change on my ex-Prius/Corolla in the past.

Or shall I have Mitsubishi dealer (20 miles away) do the job for $29.99 (no mention of balance/mount).

There's Walmart, Costco, and Discount Tires near me. Idk if it cost effective.

Also is wheel balance/mount necessary?

Thought?
