I have decided that I am going to use 12-13 Raptor rims for my snow wheels. I am just debating whether to use the 35 inch BFG All Terrain TA's or put on Bridgestone Blizzaks that come in around 33 inches.
I have a 2013 FX4 Ecoboost with 3.55 gears.
Any thoughts?

 

The TA's are better in deep snow, the Blizzaks are better on ice.

 

The nitto terra grapplers are a good winter tire also.

 

Goodyear Wrangler Duratrac's are a really good viable option as well.

I'd stick with 33's for whatever tire you go with, if you want a tire bigger than stock. A 315/70/17 (35) has about a 1" wider tread width than a 285/70/17 (33). Skinnier tires push better through snow than wider tires.

Plus I don't think BFG AT KO's are rated for severe snow in a 315/70/17 size.

 

Generally, the more aggressive the tread, the better it will pull through deep snow. However, you need a relatively tight-treaded tire with hydrophilic rubber compound and siping such as the Blizzak for best traction on ice.

 

I run Blizzaks in Calgary 5 months a year. They have been fantastic for me, and ice traction is phenomenal. I have driven past other 4x4's on icy hills in the city on bad days. If you are going to run separate winter tires on separate rims, then it only makes sense to run a pure winter tire, not an all season.

 

this. so makes your decision on your needs

 

I ended up going with the BFG's. I found an awesome deal on 5 raptor take offs with sensors.

 

BFGs are not good on ice. I run blizzaks and they are amazing on a truck with the weight. Bite bite bite.

 

Tires are one of those things that are fairly hard to return. Not impossible, but YMMV.

The BFG's are definitely a prettier tire, but for a Canadian winter, I think it was the wrong choice. Reminds me of a saying an old friend used to always repeat. His cars were almost always ugly, and rusted, but extremely mechanically sound. His words were, "Paint don't get me home".

On a freezing rain day in southern Ontario, those BFG's may very well not get him home, but they sure will be pretty while that sexy truck is in the ditch, or wrapped around some poor sap in a civic he rear ended.

Blizzaks stick to ice.

 

siped and studded if you want to keep the shiny side up.

 

Problem solved

 

One thing nobody mentioned is width. Too wide of a tire - no matter what tire you're running - will absolutely kill you in snow and ice. Believe it or not, narrower is actually better. Don't believe me? Just look at any WRC rally car running in snow.

 

My objective was to be able to traverse colorado paved passes in blizzard conditions with the highest degree of safety margin as well as back roads in the high country that stay pretty much snow-packed from November through March.

Blizzak DM-V1's in 285/75-17 on Raptor wheels has worked out extremely well for me the past two winters. Will put on a fresh set for this winter. AT tires, even those with snowflake ratings don't do nearly as well in those conditions, except maybe a few of the Nokian tires, but they aren't available in appropriate sizes for an F150. (IMHO).
