This is my 18 with a 2.5 front strut spacer and a rear 3" block kit. Just so you have an idea of what to expect. I've ran this setup on all of my f-150s with no issues.

 

I assume you mean worse mileage? How noticeable?

 

 

I've run a few different types of tires over the years, terra grappler included, and that is a great tire.

 

Yup, those are the ones I was looking at.

 

I ran the old Terra Grapplers (pre G2) and they sucked in snow. Otherwise they were good tires. Not sure if the G2's are better in the snow or not?

 

 

I had the pre G2 as well. I wouldn't say they were terrible in snow (at least imo) but they weren't great either. After the terra grapplers, I switched to the trail grapplers and they were quite exceptional in snow, mud and rain and they lasted me a long time. I rotated every 3-5k miles like my life depended on it though. Then i got a new F150 and ran BFG KM2's but didn't get to test them out for long as i switched to a super duty and currently running the stock Goodyear wranglers (I think). Looking for new tires for the super duty now actually.

 

Me too.... after the Terras, I ran Trail Grapplers on my next 2 trucks and loved them They were great in rain, snow and mud. The only downside I saw with them is they are heavy as hell,but I didn't care about weight at the time. I would've gone with them again on my new truck, but I wanted something lighter this time so I went with Duratracs.. In the size I went with the Trails weighed 76.83 lbs each and the Duratracs weigh 61 lbs each.
