    Hi guys,

    I have some Cooper Zeon LTZ 255/55/R19's on my LR4 and am wondering about deflating them for off-roading on rocks and sand. Does anyone have any experience deflating these tires? If so, what pressure would you recommend going down to and do they handle deflating OK?

    Also, does anyone have any recommendations for a pump for re-inflating? Ideally I would like something that can be powered from a 12V port, is relatively small, but isn't likely to break on me. I've seen quite a few cheap ones that seem not to be so reliable.

    Thanks in advance!

    I have these tires and have not deflated them for off-roading, nor would I recommend it, at least on any rocky terrain. The sidewall is just too small and not as strong as an e-rated tire to withstand much, and the rim is pretty close to the ground as it is. They performed great without deflating them when I've had them on Colorado trails.

    I do cary an air pump, but it clamps directly to the battery and not a 12V outlet. At least when I was shopping for one, a 12V port wasn't enough juice to power a decent air pump. This is the one I have; it's been good for my limited use: https://www.amazon.com/Inflator-Por...+SuperFlow+High-Volume+12-Volt+Air+Compressor

    I used a Vi-Air portable compressor for years before I mounted an ARB under the hood.

    It worked pretty well. I did require you to clamp it onto the battery, and not a 12v socket, though.

    Thanks for the recommendation Ryan, and good tip on deflation. Have you tried or would you recommend deflating a bit if driving on sand?

    Sand would be better as you probably wouldn't be worried about sidewall damage.

    I think others have posted on here that these tires are excellent in the sand after they've worn for a little bit. You might search for that thread and see who posted it to ask them about deflation. There's not any sand anywhere near me so I've never driven on it.

    Great, will do.

    This is my second set of these and I've never bothered to deflate them before, but have driven on plenty of rocky trails and a little sand, but I'm planning on doing some potentially tougher ones so would like to be prepared.

    And thank you - much appreciated!

    I don’t know about the cooper tires but my good year wrangler duratrac do fine in the sand. I Have done a lot of beach driving with them in some pretty soft stuff and running them at the 32psi front and 42psi rear has never given me problems. On my old Range Rover with 20” rims I actually would air up when off road on rocks(not the greatest for traction but it saves a trip to the tire shop) The one time I didn’t I pinched a sidewall on a surprisingly small rock and had to drive out on the spare. I wouldn’t air down unless bogged in the sand. Doesn’t take much to flex a low tire and pinch it on the rim
