Airing down the stock 20" Goodyears in Snow

Anybody done it? I've aired down plenty of tires in my wheelin days but never on a 50 series tire with a 20" rim. Don't want to break the bead and end up stuck in the mountains.

Re: Airing down the stock 20" Goodyears in Snow

I don't know about for snow, but I aired down my 20s for beach driving this past summer and had no issues. I went down to about 22 psi or so; some go lower. The issue is that things get pretty "squishy" on dry/hard pavement when the tires are aired down. (EVIC will also complain at about 29 psi) This winter...the snowiest we've had in many years...I've been running at normal pressure, which for me is 38 cold.

I wouldn't for city/highway snow-driving. If you are wheeling, then maybe.

Re: Airing down the stock 20" Goodyears in Snow

Thanks guys. To clarify, I would only do this on a trip up the mountain logging roads with a couple of friends to play around in the snow, have a fire, and so on. The snow could easily be 2 or 3 feet deep. I wouldn't do this for regular snow covered highway roads. We've done this for years with more hardcore Jeeps and trucks and airing the tires down works great. I have a nice little 12V air compressor that pumps them up quickly when I get back to the highway.

In this case, my concern is specifically with the 20" tire/wheel combo. I suspect a lower profile tire (like a 265/50R20) has much less ability to hold the bead when the air pressure is lowered.

cheers.
