PSI for Red Grabber 35" in Snow

Any difference with PSI? I don't normally drive in snow. I think they're at 35 PSI right now. Should I change?

Anytime you lower your psi it creates a wider footprint and more traction due to the tire also being able to confirm around whatever is under it. So yes if you lower your air pressure more of the tread will be in contact with the road giving u better traction. But I personally wouldn't get carried away if I were you. If you know your going to get a particularly snow stretch of days then you could drop them a few lbs but if your hitting the dry highway at speeds running low pressure can be dangerous. Truth is, even on snowy roads there is still often times enough pavement to get traction. That's my opinion. For trails or mountain roads that's a different story, air down it makes a difference. I'm talking about paved maintained roads.

I run mine at 25psi on the road year round With a 8" wide wheel. They have worn evenly and have plenty of grip mine are about 2 years old and have 50% tread left. After 20k miles. Offroad I drop to 8psi. At 35psi yours will most likely wear uneven.

Yeah good point, I suppose I just assumed he/she was in a jk (bad habbit of mine). If the OP is in a 4 door then 35 might be pretty close if you do a chalk test a 4 door has a lot more weight than a yj.

OP what are you running them on?
