Spare tires different trim, and tire size. Lower the tire and read it.Okay. Why do you think the limit is 50 mph when the Owner's Manual says it's 70?

It says max speed is 50 mph?Spare tires different trim, and tire size. Lower the tire and read it.
That doesn't apply to the Lightning. The front and rear axles aren't linked through a transfer case like traditional AWD vehiclesApparently AWD systems don't like the mismatch.
Ah, so AWD from an EV is not the same as AWD from an ICE? I'll have to research that, I'm barely familiar with the difference between 4 wheel drive and standard ICE AWD.That doesn't apply to the Lightning. The front and rear axles aren't linked through a transfer case like traditional AWD vehicles
That doesn't answer the question. Why does it say 70mph in the manual?Spare tires different trim, and tire size. Lower the tire and read it.
I'm definitely not a lawyer, but it seems to me that Ford would be opening themselves up to litigation if I follow the direction on the owners manual and that results in an accident. I found several other Ford owners manuals that all say 70mph for a dissimilar full sized spare. I feel like my compromised speed of 60mph was a good choice.The information stamped on the tire is the ultimate answer. sure you can cheat a bit, but what the manufacturer designed the tire for is the ultimate safety factor. No different than what the Ford stamps the tire pressure on the door jamb, the tire manufacturer stamps the maximum tire pressure on the tire. Owners manuals are not updated as well as they should be. Maybe the truck can handle the 70mph as printed, but the tire was not designed to handle that speed.

The manual for my 2023 states 70 MPH, but 50 MPH in 4 wheel drive. Probably a carryover from the ICE manual.That doesn't answer the question. Why does it say 70mph in the manual?
