As capable as my 2000 SR5 is in the snow, I feel as if I'm not getting a good bite and that i'm "floating" on top instead. I have 265/70/16 REVO's and I'm running them at 33 psi all around. In the past, I used about 200 lbs of sand bags in the back which improved my bite somewhat, but I hate hauling the extra weight if I don't have to. Any suggestions?

 

Your tread is probably loading up with snow and losing its effectiveness. Short of buying a more aggresive set of tires I think the extra weight is your best bet.

 

a more narrow tire perhaps? Also, how much higher can you inflate the current tires keeping within their limits and wearing properly?

If I was in your situation, I'd fully air up my 6ply's to 50psi so as to break through any snow, but I dont live in a place that has that white, fluffy sand falling from the sky....lol

Don't add more air if your trying to get more traction!! If anything if your driving in the snow a lot I would consider airing down to around 28PSI and try that. You won't have any adverse affect at that pressure but I would air them back up if you are only driving on dry pavement or are going on a road trip or something.

 

I agree with lowering the pressure for traction. Raising the pressure will make you more susceptible to hydroplaning and the back end breaking loose on ice patches.

 

I don't like carrying extra weight either. I aired down from 32 psi all around to 27 psi in the winter. Seems to be noticeably better.

 

Thanks, gents. I'll be airing down this afternoon.

 

oooooh you meant like 1" thick snow or so and then icy roads and whatnot.....

I thought you were driving on top of deep snowdrifts and not breaking through them to solid ground....hence the narrower tire and increased tire pressure comment.

 

going to 28 psi wont make that much of a difference. Try going down to 12-15 if you arent going very fast.
