Thread: 2013 FX4 with 20" wheels for snow tires

What tire size did you go with on the 18s and how much did they run you??

Will the 18's clear the rotor?

And are you looking for just winter tires? Or like All-terrain or off-road, or all season?

I got bigger tires when I upgraded from 17" wheels to 18". I went from 265's to 285's. Thats where it got thrown off lol.

That's what I thought

285 is width not height. So speedo is off when you adjust diameter. Looks good!

285 is definitely not the width or your tires would be half as wide as your truck nearly. The smaller number like 285/70, the 70 is the width.

I'll have to disagree 285 is the width of the tire in mm. 70 is the aspect ratio or proportional height of the side wall.

Grabber. 285 is the hight and 70 is your width. Only dirt bike tires do width first

The above calculator helps you compare your stock tire sizes to what you would like to put onto your truck. It also gives a speedometer difference comparison.
