When you don’t know to thank or to hate, that’s called love my friend! You’ll like those!

I run them at 46

Just like a golf ball flies farther in higher elevation… less air density = lower drag. Imagine in out space there’s no air - then drag is non existence

It actually has big impact. I’m at 1500 feet and when I go to sea level I lose about 5%

I don’t think it makes a difference at all.

Not enough to be sure. But will keep an eye on that.

Those probably have stiffer side walls, which is a good thing. I love the SLs because they are so soft and quiet, but for spirited drives, they are a little soft.

Wow - surprised! So many variables!

so the tires weigh exactly 48 lbs! that's how much mine weighed - consistent!

What do the wheels weigh? Let us know how the efficiency does!

Wow, I didn't know they made them in 33" Let us know how the efficiency runs on those!

We got an r1s cause the lease was half the price of a wagoner lease. No brained. Wife loves it.

Thanks! To me, efficiency was never an issue until i started towing. A 1.1 vs. a 1.3 is a big enough difference to force a charge or not in certain legs of a trip. For example, with my old Pirellis from Atlanta to Savanna, i would need to do 4 charges, 2 of which were at 50kw/h stations. These...

Well, yes. But my post was a comparison of tires holding most things constant. this post want about who is getting what efficiency from the oem 20 at tires. but it also proves that elevation and temp are really important, but not for choosing tires….

Thanks. Exactly what my point is… focus on the comparison, not on the specific tires’s data point.

What’s your elevation? Want to see if everyone with higher than 2.0 are still j high elevations….

2.2 is amazing. Far from my reality on the oem AT. even in this post I would say most people are below 2.0 and closer to 1.9. Maybe you live like in Denver or higher elevation? That may get over 2.0 m/kwh. I don’t sell tires for a living and don’t need any commissions - I believe my numbers...

Agree. I thought anything over 2.0 was deserved for Mrs. daisy

Those calcs net about the right numbers... or close enough Wow - those are great numbers for the OEM ATs - I don't know how to explain it other than I need to offload the truck from all the stuff in the bed, fronk, and tunnel lol
