I don't know how all the math works out but from what I understand they went with their 11% reduction to be able to run 38's with the 4.70 gearing and have it feel and act like the factory "35's". So I could be totally wrong, but with the same reduction, the 40's are essentially equivalent to...
MPG? Shit to none. Kidding. So far seems to be about the same as before portals when I had 37's. Around 13.5 average. I dont know how I see so many people claiming 18+ on these things. Even when I had the Stock "35's" id be lucky to get 16ish. Maybe it's where I live. My Bronco is not a commuter...
Well see what happens when i get it flexed out. From reading the 74W portal thread and seeing what all those guys tried and their experiences, I fully expect some rubbing and some new projects to resolve that.
Tire poke is 3.5" front and 3" rear.
Vertical tire and fender gap doesnt say much as it will all depend on where you have your suspension set at but im right about 8.5" front and 9.5" back.
Thank you! Leagues behind your rides but coming along.
Outside of tread to outside of tread is about 85.5". Outer side wall to side wall is probably about 87.5 with eye balling.

She's done! So far drives amazing. Went with Method 709HD 25mm offset and 40x13.5x17 Yokohama Geolandars. Loved the same tire in 37's and they are surprisingly light.
