Looking to pick-up snows for my 06 FX4 screw. My plan is to run snows on steelies so that would open up size options other than 275/65-18. What alternate size snows are others running in this application?

 

245/70/17 is what i use on my 06 XLT. Most people with F-150s in my area of Ontario seem to run that size, and the dealership usually recommends this size as well. It does throw the speedometer off but i use my edge to fix that.

 

I did this same thing last fall...

My stock wheels are 18s with 275-65-R18 tires... I bought some 17" wheels so I could save money on buying snow tires.

I wanted to minimize the difference so I bought 265-70-R17 snow tires.

By my calcs, the rolling diameter of the stock 18s is 32.1 inches. Using these 17s it only decreased to 31.6 inches. This is only a 0.3 inch change in radius so there was minimal shift in speed or distance.

But I still adjusted it with my Edge to get it right.

BTW - I bought P265/70R-17 Firestone Winterforce UV tires and they handled great all winter. We got tons of snow and ice this year too.


PS - if you go to the 245-70-R17 tires you will be decreasing the rolling diameter to 30.5 inches. This will drop your ride height by 0.8 inches and have a greater affect on your speedometer.

 

I use 285/70/17 Bridgestone Blizzak DM-V1. They are actually a little larger than the stock 275/65/18, but is a little more odometer friendly than putting smaller than stock sizes on. Saw thier first Alberta winter this past season, and didn't dissappoint at all. The Bridgestone site lists them as a 32.8 inch overall height.
