I need my truck in my garage. It's 1-2" to high. Don't know when my new springs are coming. How bad of an idea would it be to deflate the tires enough to make it fit and leave them deflated?

Did this for years, no issuesI can drive right up to the garage. It's paved. Just more concerned with long term storage at decreased pressure.
Just realized I could drive it in and pop the tires off and let it sit on jack stands.
How long? I've always pulled the tires if it's gonna sit and they have to be aired downI'm talking about driving it from behind the shop to the front of the shop, dropping the pressure, and driving it into the shop. That part I'm not worried about. My concern is leaving the tires at say 20 psi for long periods of time instead of fully inflated.
Agreeif you get to the garage . drop them almost flat or to flat and its all smooth from there to parking spot you can about run them in on almost no air .
dont turn / put in low range let it crawl .
if your talking the 37" tires in your sig line you should be able to drop them a lot and still be safe .
At 20 psi you can leave it for years.Dunno. Depends when my new springs ship and I get the time to install them. Could be two weeks, could be a month. Who knows what this dang virus is going to do to my delivery.
