Tire recommendations?

[PnchDrnk]

Hey everyone,

I'm sorry if this has been asked before but I was hoping for some clarification. I am looking to get some new tires for my truck and was looking to size down to hopefully save a bit on fuel economy. My truck currently has the OEM 20 inch rims with the stock tires but would like to get a new set of All Weather tires with the M&S rating to use year round. A couple questions I have are:
Are there any particular tires anyone would recommend?
If I was to size down to 30/31 inch tires would that improve my overall fuel economy that would be noticeable?
I've heard other users talk about needing to re-gear when sizing up. Would I need to do the same while sizing down?
Are there any cons in general about sizing down in tires?
We mostly use the truck on pavement but do go overlanding in the summer and get a fair amount of snow in the winters here.

Thanks!

If I may, may I offer my recommendation? It is the tire I recently purchased for my 2021 F-150 Lariat FX4 SuperCrew.

Michelin Defender LTX MS in Ford’s recommended OEM 275/60-R20 size. Fabulous smooth and quiet-riding tire with outstanding grip in all weather conditions — and with long tread life, to boot.

Despite its overall 33-inch diameter, this Michelin tire is also good for fuel economy because its rolling resistance is low.

A tire with a smaller overall diameter of 31-32 inches is going to roll in more revolutions per mile … and increase the engine RPMs a bit more per mile … and hence use more gas. So I don’t see the logic in going to a smaller diameter size for what you hope to achieve.

Sizing down could raise RPMs, actually using more gas.

Pretty hard to beat the ford engineering. If you’re only looking for mpg then stay with stock tire size and tire weight.

No reason to go smaller, plus your truck will look worse to boot.
