Tall and skinny isn't always best. I run 33 x 12.5" tires. Without ballast, I have trouble, but with it my truck is unstoppable. I found out I needed ballast the first time I plowed. I added 4 bags of salt between the wheel wells, and did MUCH better. That was my first season with the tires. The next year, I added sideboards to my truck. I also began carrying a snow blower, ramps, and a gas can along with the salt I need. The extra weight works wonders for traction. Oh, and the tires I have are Cooper Discoverer or Discovery. Basically an all terrain tread like a Goodyear Wrangler. They were on the truck when I bought it, and had a few hundred miles on them.
We've tried several brands of tires, settled on Cooper "Weathermaster" as the absolute best snow traction tire on the market. And not terribly pricey either, I just bought 4 235/75-15 and 4 265/75-16 LT for under $600 mounted and balanced. The Coopers will out push Hakkapelita (sp) and Hakkas get good marks for traction.
If you're in an area wher the is never much accumulation from previous storms you can probably get away with lesser tires, but up here where it may get to 2' sitting on the ground and hardening up, you need all you can get if you get off the beaten track.
We, too, like the Firestone products. They're especially helpful to our Fords when the snowplows won't drop; all you need to do is roll the vehicle over and the plow drops just fine. We call this dual mode plowing.
Does anyone know if GM 6 lug wheels, are the same 6 lug pattern used on mid 70's Jeep Wagoneers? I know GM 6 lug rims fit right onto a Toyota pickup, and late 70's Datsun trucks.
A friend has a set of GM 6 lug wheels for sale, and has someone interested with a 70's Jeep Wagoneer, 6 lug. They are a few states apart, so they can't "try them on". I guess they can both measure what they got, but thought someone here might know for sure.
I'm really surprised no one has mentioned "sipes", or having tires siped. From what I've read, they make a HUGE difference in traction on ice.
A sipe is basically a cut across the tread of the tire, about 5/16" deep. No material is removed, only "slitted". They are done every few inches around the whole tire.
That's why you keep hearing the Michelin ads saying "With Y sipe technology". They make tires that have sipes, but from what I've read, having them siped at a shop provides more traction.
I read that sipes were invented by a boat fanatic. He found by making small slits in the soles of his shoes, he didn't slip on the wet deck of the boat. Go figure!
Siping is an excellent traction booster. Only problem is finding a shop that can do siping, It's pretty much lost technology. The siping on those Michelins is molded in and nowhere near as good as cut sipes. I've run siped Bandag retreads and the "commercial traction" tread with siping was excellent for traction and seemed to wear longer than the unsiped version of the same tire.
