Snow chain question

Hey folks random question. First off, I run snow rated tires and air down in the snow if needed while playing. However if the situation turned for the worst and i needed to use chains, do I have to air up or can I leave the tires deflated? What’s your experience?


Never mind I found a link!!

Never been stuck in a mail truck with snow chains. Tires are always aired down and bald because we have Chevrolet dealership for repairs.

 

I always run normal inflation pressure with chains. You need higher ground pressure to make the chains dig into the compact snow and ice to give you the traction.

I have run 12 psi on my front tires (no room for chains), with 30ish psi rear and chains on. There was no concern about binding between the front and rear in those conditions, and they were desperate conditions. The combination seemed to work fairly well, as we made it out without waiting for spring thaw.
