Pizza Cutters?

I added 255/80-R17 BFGoodrich HD Terrain tires this week. They really fit the character of the vehicle. They give me modern Michelin XZL vibes.

Stock suspension, and the rear door clears just fine. Speedo is now dead nuts on.

We are going to record an Overland Journal podcast on my most recent modifications including these tires.

What is your experience in fuel efficiency? Do narrower tires move the needle? In theory they should be more efficient. But is it so in reality?

In concept a narrower tire has less rolling resistance and less weight than a wider tire. So assuming the tire was the same diameter and tread pattern, the narrower tire would have potential to be more efficient.

So, reading between the lines; you are saying no. In reality you have seen no measurable improvement in MPGs.

Someone has had to do some real world testing?

Whenever I decide to swap the factory Bridgestones it will be for 255/80R16 MT’s. Just the fact that this will add almost 10lbs/tire says NO improvement in MPG’s.
