Have you found the SL275/65/R20 available anywhere?

Tire rack has plenty.

I've never used Tire Rack...Perhaps this is a stupid question: I see that they include road hazard protection for free. Do they do that even if I have them ship to my local tire place and have them installed there?

I always get the road hazard protection, but my guy charges me $25 or so per tire for it.

Oops, forgot to look there. Checked Discount Tire and a few others. I think this is what I'll go with this spring since I'll only do light off-roading with my R1T. Mileage has got to be better than the LT option(s) with 13 lbs less weight.

However... Wiki on Tire Rack: "Tire Rack is a privately owned customer-direct tire, wheels, car accessories distributor company headquartered in South Bend, Indiana. In 2021 it was acquired by Discount Tire and continues to operate as a separate business and brand name."

Many posts on buying from TR, shipping directly to local Discount Tire. For convenience, you might want to just ask your local / receiving Discount Tire if you can get their protection plan instead of Tire Racks—so if you ever need to make use of it, you can take immediate action through DT instead of having to deal with TR's claim submission and approval process.

People on here have said the SLs would not be able to tow, but they are the same rating as the Pirellis and I talked to RIvian CS about this specifically and they said the truck will have it's full towing capability with the Pirellis or same rated tire. I currently only pull a 3500 lb Bambi so no worries for me at all with the SLs.

No one said that. It's only not ideal when load, under towing, exceeds the SL-rated tires' load limits.

Does anyone have any real world efficiency data on the SL version of the Toyo OC A/T III on a Rivian? I'm leaning towards the LT as it seems to be about the same as OEM but would be interested in the SL if it's 15-20% higher efficiency as some have predicted. I'm at 17K on the Pirelli 20s and the noise is unacceptable.

I have about 1000 miles on on the SL version and I’m around 1.98 kw/mi. I drive 70-75 on freeways and fluctuate elevation. Weather has been cold the past 2 weeks and I went from 2.00kw/mi down to 1.97. I love these tires, I feel they’re more comfortable than the OEM Pirellis, and drive the same as the non-EV version which I had for many years on another SUV. Handled great in light snow, and quiet for an AT tire on the highway. No complaints other than trying to get my average up without letting up on acceleration/speed.

Hope that helps.

Thanks for the data. I'm confused by your efficiency as many are claiming the LT version has about the same efficiency as the OEM Pirelli. With yours being ~2kWh/mi it seems that the LT and SL are roughly the same? Or at least the SL is not significantly higher than the LT. This doesn't make much sense because the SL is 0.5" narrower and significantly lighter so should be more efficient.

Thats my issue too. SL and LT versions have a 13lb weight difference and about a 3/32nd tread difference. I would love the E rated LT's if it was similar to the SL. Dilemma i'm having now.

Others with more experience with the LT tire have stated that efficiency is about the same as the OEM Pirelli (~2-2.2kWh/mi) but with better performance off road and in snow/ice. I have not come across an owner whose efficiency with the SL is any better than the LT/OEM Pirelli. Unless I hear otherwise, I will get the LT as I do challenge the tires off road. I had a rock take a chunk out of my wheel last year and shudder to think what it would have done to the 2 ply Pirelli sidewall. OTOH, if the SL version is ~2.4-2.5kWh/mi I would limit my extreme off roading for the benefit of much great range.

[SL rated tire] may have 15-20% higher efficiency [than LT version] as some have predicted.

I've seen this prediction too, and I continue to disbelieve it. The most efficient wheel/tire combo that Rivian sells is only about 13% more efficient (using rated range as a proxy) than the least efficient wheel/tire combo. If a dedicated range tire on a dedicated range wheel is only 13% more efficient than the standard AT wheel/tire, it seems impossible that the SL version of the same tire could be 15-20% more efficient than the LT version.

I'm buying tires soon and you nailed the exact same point that is driving my decision. I'm looking everywhere for more input on the SL version.

I don’t understand how people are averaging higher kw/mi. It might be the frequent elevation change I do on daily commute, my highway speeds returning home (going up elevation), and the cold weather we have been experiencing. I do average 72-74mph on freeways. Any input from folks would be appreciated.

When I drove from San Jose to South Lake Tahoe, my average was 2.0Kw/mi. It would have been higher had I not preconditioned battery before charging at a new RAN in Placerville. On the return from Tahoe, I did not precondition to test it out and charging rate was about the same. The charging is precautionary in case any issues on the road - don’t want to worry about battery if stuck in slow traffic.

I honestly believe this is a much better tire. If you are not going to do heavy towing or do major off-roading trails, then the SL is a great tire. It’s perfect for my lifestyle, of light trails, and on-road uses. I feel its improved daily driving comfort and handled really well in the light snowy roads in Tahoe. Having had the OC ATIII on my previous ICE SUV, I’m a big fan of the tire in snow. Handled great. This version feels the same to me.

My other choices were the Bridgestone Dueler (mentioned previously) and Nitto Tera Grappler G3. Those to me seemed to be on par with this tire. Would be interesting to hear from anyone with those tires.

I have the Dueler Revo 3's
The Trip B odometer is new tires only - reset when I purchased them
Mostly highway - Chattanooga and Huntsville
A few days of snow recently in Chattanooga - handled well, but in town speed was very limited
The last picture I could find of my mileage/efficiency was 11-25-2024
