Which wheel & tire combo gets the best range?

[Major Payne]

Full disclosure, I know very little about these trucks, but am considering a purchase.

Both R1T 2023 dual motor Max Pack, each with different tires and wheels.

• Michelin Defender LTX 275/55 R21

• Pirelli Scorpion All Terrain 275/65 R20

Mostly Southern California driving, range-wise, which is the better tire/wheel combo?

The Michelin Defender LTX 275/55 R21 would have significantly better range but they could be a pain to replace due to the 21” rims not having as many replacement tire options.

One consideration is that there are far fewer 21" tire options than 20". There is also the issue of All-Terrain vs AS. The latter will offer greater range than the former due mostly to differences in rolling resistance, and will also be quieter.

The Michelin LTX 275/55R21 is an all-season tire with a diameter of approximately 33" used by many who praise its handling, tire mileage and improved EV range. You can get roughly the same diameter on a 20" wheel using a 60 series tire (275/60R20), and there are many options to choose from..

My R1T came with Pirelli Scorpion 257/65/R20 AT tires, good but noisy. I don't have a need for true off-raodeing, so changed them for General Grabber HTS60 275/60R20's shortly after taking delivery. The Generals are quiet and provide both decent handling and good range. While they are not quite as good as the Michelin Defenders, they are considerably less expensive, a trade-off I can live with. I haven't done a true range test, but estimate that I average somewhere in the 2.5 - 2.7 mi/kWh area with the Generals. Even on the low end of the range, that means 320+ miles of range from a G1 Large pack (131 kWh.) Much of my driving is in the PHL suburbs, but also includes time in some of the hillier areas of the Poconos in eastern PA.

I got my R1S w the 21 AS. Wish I had done the AT. I also am primarily around town user, but there’s only 2 choices on replacement tires. I went with the Michelins, good choice.
But don’t forget curb appeal. The ATs look better (imho). And I wish I had a treadier tire. But I’ve never experienced the noisier attribute of the AT. Grass is always greener.
Good luck.

I replaced my 21" OEM scorpoin Verde's as soon as the Defenders were available. Better tire, not sure there is a charge range improvement, but the 21" by size is.
The Defender is great in the snow where I live. I think tread life is going to be almost double, but the charge range the same.
As for looks, if I need to look tuff, I will get a camo bumper sticker.

Now that it's possible to swap wheel sizes in vehicle, without going to a service center, I wonder for those with 20"AT wheels/tires, is there a range increase putting on a 20" All Season in the smaller 275/60-20 size on the 20" AT wheel, and will that increase range over the 21" AS OEM wheel/tire combo, similar to how smaller wheel combos on the Tesla models typically increased the range/performance on the same models? Are the 20" AT wheels significantly heavier than the 21" OEM wheel? Would going with a forged 20" that's lighter than the OEM, with a highway/range focused AS be possible for those looking for ultimate range? Anyone have AS Range Tire suggestions for the 20" in the smaller 275/60-20 and the larger 275/65/20 size, other than the OEM Goodyear (more of a mild AT), that comes with the standard models, that are more focused on-highway/range? I'm also curious for range, is it beneficial to go with the smaller 33" tire diameter, or the larger 34" AT size, in an AS Tire. Need Out of Spec to do a test of this!

Hi all, I’m an engineer at Goodyear that helped develop the Goodyear Territory AT for Rivian. This tire performs well in a wide variety of conditions. Efficiency was a top design priority. Updating the software from the OE 34” AT to the Goodyear 33” tire improved range from 369 to 385 miles on my R1T. @DayTripping has documented impressive efficiency numbers with the Goodyear tire in this thread… https://www.rivianforums.com/forum/...-20-factory-at-tires-saving.37522/post-753458

I have to say, the efficiency of the Goodyear is what has surprised me the most about the tire. This is even more amazing to me is that efficiency wasn't even in my top 3 reasons of putting on a different tire.

I had considered the Michelin LTX series but they were pretty narrow and the Goodyear was much wider, had better traction ratings and was still pretty lightweight. The surprisingly good efficiency was just an unexpected bonus. I really wanted good traction and wasn't as concerned about treadlife as I wanted good capabilities when I drive aggressively or in emergency situations.

I'd say efficiency was probably #4 or #5 on my list of priorities. I wanted a good all around tire and honestly if I could have bought something like a Michelin Pilot Sport 4s for my quad for most of my driving but this tire has impressed me in so many areas that if I get decent treadlife, I'll buy another set of the same tires (or its successor in the line) which I rarely ever do.

Just to add to this. I only have about 14k on my OEM 20". I've done a lot of research and everything points to these tyres. Keep in mind, my goal is a butch looking tyre with good efficiency and less noise. The Goodyear win on all accounts.

Please, look up the detailed thread that @DayTripping did. Lots of good information.

The Goodyear sounds like a winning combination for you!
