Say I had TSL Swamper flat, and left it that way fo a long time (maybe a month). Would it hurt the sidewall any??? Reason for me asking, if your curious, I will need to practically flatten the tires to get it in the garage (where it's stored). As it is right now, 3.5 psi gets me in the door. I'll need to go lower, I'm adding some height to the cage front. I just don't want to ruin my 42's by leaving them flat. I'll air up slightly in the garage, but only if I have to.
