Upgraded to 285/65/20 KO3 tires + 2" inch leveling kit -- impressions and efficiency difference

[LawGator]

I went with a 3" lift and 295/70/18 KO3's

I live in SoCal, so its NOT cold.... my range went from 2.1 down to 1.7, but the overall look is well worth it for me!

Which lift?

Which lift?

Eibach Pro Stage 1 for SR trucks - this was the test/prototype mule to develop the SR kit, so not sure if it is available yet to purchase or not.... but the ER kit has been out for a while now

That's sharp. Any benefit to a complete replacement of the shocks and springs like that lift has over just spacers?

Hello, I purchased my lightning in may of 2024. My previous vehicle was a Jeep Gladiator diesel Rubicon, on 40 inch tires on a 5 inch coil over conversion. That truck was amazing, but was getting too small for my family. After my wife got a model 3 I was convinced that the lightning was the truck for me. It took a couple months of driving the stock setup before i was ready to upgrade the stance. I was contemplating going with raptor takeoffs, but a lot of people on the forums said that the wheel cant support the weight of the truck, and some have fitment issues with the 17's. I decided to do a OEM plus look, and try to keep as much efficiency as possible. I decided that keeping the Lariat wheels would possibly help with aero and going with lightweight 34.5 would be a middle ground. I also wanted the smallest amount of lift possible to fit the tire. After deciding on the Ko3 as the tire of choice and the size of 285/65/20, I went to discount tire and got them mounted up. Discount decided to fill the tires to 40 PSI, and that seems reasonable to me. After doing my regular work commute for about a week, I calculated that I lost about 10 percent efficiency. Monday I then inflated the tires to 50 PSI, and it seems it has given me back around 5 percent of the efficiency that i had lost. The way i calculated was getting the battery percent used during my commute, and converting it to KWH, then dividing by the actual amount of miles that the commute is. The speedometer was never corrected, so the truck thinks I'm driving a shorter distance than I actually am. When GPS says I'm going 65, the truck is at 62 as well. Overall it is a small efficiency hit for a major upgrade in the looks and capability department. I attached some after tire change photos, and a photo of the Guessometer after my drive to work this morning, keep in mind though that the mi/KWH displayed is inaccurate now, 2.0 is more like 2.12 mi/KMH

Love the look of a factory wheel with off-road tires. Especially with these lightning wheels aggressive tires seem to make the wheels look more aggressive imo
