my blazer does have a 2 1/2 inch lift. but wouldnt the 10.50 be better in the snow than a 12.50? would it be noticable enough to do that or am i better with 12.50(i think the 12.50 looks beter than the narrower ones)
Kinda off topic do i lose any traction on snow by have a factory GM locker in the rear?
I'm up in the air on tire performance. Tire performance in any condition is going to at least partially be dependent on tread design. Vehicle, tire width, tire height, that all matters too.
If you can get down to solid ground, a narrow tire will work better. Otherwise it is better to spread the vehicle load over a larger area.
AT tires typically don't self clean well. Deep snow and mud is likely to present a problem for them. My BFG AT's seem to clog in deeper snow, I've yet to try airing them way down to see if they do any better.
Street pattern tires do a better job in my experience on very slick, smooth surfaces than even an AT, but an AT should do better than a more aggressive pattern in the same conditions.
BFG's do wear good, if you've already got a lift and plan for the variety of wheeling you do, I'd be thinking about 12.5" BFG MT's. Narrow tires get you better economy, AT is going to give better on road traction, and should last longer, but deeper mud and snow would be better handled by an MT IMO.
Factory locker in the rear can be quite interesting in the snow and ice. If you are light on the throttle, it can and will send the rear sideways. Sidehilling could be deemed dangerous if it isn't locked, then locks when you aren't expecting it and the vehicle swings. BTDT. No different at that point than any other automatic or full time traction device, like a posi or detroit. However, with a posi or detroit, the rear will start to react INSTANTLY, and you know exactly when your rear is starting to slide, whereas the gov-lock will likely let you get in a bit over your head before it starts to let loose.
