Tire Weight vs Rolling Resistance

[Boodro1]

I'm in the process to researching new tires for my truck. 2019 F150 fx4, 95% pavement, and about 60 highway miles per day. Currently have Pirelli Scorpion All Terrain Plus XL's. They've been good but are getting loud and uncomfortable, so looking to go with a milder on-road all terrain tire. On my radar are the Continental TerrainContact AT2, and the BFG Trail Terrain T/A+. The Continental lists higher rolling resistance and lighter weight, while the BFG lists lower rolling resistance and higher weight by a few pounds.

My question is, what will have a more significant impact on fuel mileage, performance / feel, etc.. rolling resistance or weight?

I don't have much experience with different tire weights nor am I very familiar with the impact of rolling resistance differences. Thanks in advance for any guidance.

I think it's unlikely 2 tires of the same size and classification will result in any attributable MPG changes.

.
Rolling resistance will likely make the most impact. A few lbs extra tyre weight will make some small difference to acceleration and therefore fuel use but it's hardly going to be measurable.

Do you know what the difference in rolling resistance is either in grades or in rolling resistance coefficient. I have a table that shows the average difference in fuel use for each by grade but that's for European tyres. There must be something similar available for US tires

Researching? Then research LRR and Tire Weight, specifically on tires in which You're interested. Tire weight makes more MPG reduction on the Highway than around town. Get the most hiway friendly tire design for best mileage. Etc.,Etc.,Etc. .02

Allow to answer barryh's question first: There are no statistics available on tire rolling resistance in the US. California is considering some, but that's at least a year and a half away.

Within comparable All Terrain tires, like this, I don't think there will be enough difference in fuel economy to matter.

Weight of both tires? How much is "a few lbs"

I know in the off road world when guys go from P to LT and about 15lbs more they would loose a ton of MPG.

3 or 4 lbs probably not much?
