Announcing our new "CLUBS" section where you can join or create a Rivian club or group! You can use this new feature to conveniently plan and discuss local events, gatherings or other club/group related topics.
So we encourage you to join (or start) special-interest and regional-based Rivian clubs at: https://www.rivianforums.com/forum/group-categories/clubs-groups.1/
Great post. I would even add a third reason to air down. I have had plenty of times when I have all the traction I need without airing down but I would pop a tire. By airing down you can protect your tires from punctures. Think of a balloon. When completely full it will pop much easier. But when you roll over sharp rocks you will be less likely to puncture the tire by letting it give a bit more. Slow or fast speeds.There are two purposes for deflation. One is to increase the tire patch size for better traction and the other is to give you a more comfortable ride when off roading by letting the side walls have more pliability. Increasing traction is definitely a benefit in many situations but consider those situations carefully before proceeding. Do you really need increase traction? Are you crawling over rocks, loose dirt, shallow mud, or even water fording. Then perhaps this is beneficial.
I agree with this. Though Iām not sure it will matter on the sidewalls of these Pirellis.Great post. I would even add a third reason to air down.

This actually happened while going faster on a forest road. I didnāt air down and had highway pressure and hit a small 4-6ā rock that popped the tire. I think I may have been better to have even 10 PSI taken out.
With the 21s, Iād try to stick with standard pressure (around 50 psi) unless you really need the extra grip. The lack of sidewall makes reducing the air pressure a little more sketchy.Whatās everyoneās thoughts on the 21sā and off roading and a pressure to lower to? I plan on a somewhat moderate trail; Iād say maybe a 5/10 with a mixture of rocks. If anyone in Colorado is familiar, the off road trail to Fall River Reservoir.
Right now they are at about 47-48PSI once warm.
I don't know about the compressor, but for my GX I use Staun deflators with speed clips. They won't help you with today's trip but nothing else comes close in terms of convenience.Dumb question, heading out today and realized I don't have a tire pressure gauge or anything to deflate the tires. Is there an easy way to deflate with the compressor kit to a specific PSI?

The kit doesāt have a deflator. IMO, the best one on the market is from ARB. I also recommend getting spare tire stem valves (easy to replace) if you do any significant off road driving.Dumb question, heading out today and realized I don't have a tire pressure gauge or anything to deflate the tires.

Yeah, here's a video where someone shows this:also @Sgt Beavis I found that the chuck to air up with if you attach just the chuck to the tire works incredibly well to air down with! Just need to keep an eye on the gauge on the dash to make sure you donāt air down too much.
