Tire Size and Range

[Stovepipe001]

I have both a 2023 Lariate with 20 Inch OEM wheels and tires and a new 2025 Platinum with 22 inch wheels and Michelin Defender 22" tires. I swapped out the tires on the 22 Lariat with the Platinum tires and noticed a decrease in range of approximately 15-20%. At 90% charge on the 25 Platinum I noticed the range to be approximately 285.
2023 Lariat with OEM wheels and tires (20") was normally 320 at 90% it is now 290 at 90%. Reading up on the effect of weight at each tire I should have expected this to happen. Has anyone come across a set of 22" wheels and corresponding tires that are light enough and LT (light truck) rated that approximate the 20" tire range?

The GOM is not a reliable indication of range. Drive both on a controlled route under identical conditions and compare the MPK.

And yes, the EPA range on a Platinum is slightly lower, generally attributed to the tires/wheels.

Not sure what the offset on those wheels are, if they protrude much more than OEM, but I notice a 5-10% drop in efficiency when going from OEM Lariat to OEM (non-aero) 22s and my 22s are Heavy!, like 75-80lbs.

So I think you're looking at other things than just weight with your setup.

No, an Lt tire is always going to be heavy. You need to look at non LT tires.

Will a non LT tire be acceptable for the weight of a Lightning?
