Driving on pure ice; best PSI
 

Ok, I want to get everyone's heated opinion on whether I should air
down, and if so, how much, when I go out to race my jeep on a frozen
lake this weekend.

Mine is a 97 TJ with 4" of lift and 33x1250r15 BFG AT KO (brand new)
tires, siped (yeah, I paid for the stupid siping that Discount Tire
practically forces down your throat. I made him do it for half the
price, though, at least ;-) )

Anyway, I've heard equally strong opinions both for and against airing
down for the race on the frozen lake. Some think I should, if
anything, air up; presumably they think this will further reduce my
contact patch, but give me more PSI at that contact patch to get
traction. Others think I should air down to about 20 to 25 PSI (I
regularly run at 35 PSI on the highway) in order to get more surface
area of traction (albeit at a lower PSI at the contact patch).

What do you all say to this? I know we've had this discussion with
regard to inclement weather driving on roads, but never with the sole
purpose of getting the best performance on nothing but an ice covered
lake, with no regard for performance in any other situation...

I'm currently leaning towards the airing down to 25 PSI idea...

Thanks,
Bob

Air up air down it does not matter ice is ice and the coefficient friction
between the tires is the same. Chains or studded tires other wise you could
be hosed but what do I know?

Nice tires, Bill.

The road-kill will be extra tenderized with those!!!
