20" tire recommendations

[caiudalmau]

I put Nokian One H/T LT275/65R-20 in my R1S immediately after I bought.

I don’t need off road and think 20” rims look better. More proportionate with the size of the rig. I also wanted to improve efficiency with road tread.

I’ve been real happy with them. Mostly highway / road with a little bit of snow when going skiing up to Stevens Pass in Washington from Seattle.

I never rode on the stock pirellis to A/B the road noise. The Nokians ride quiet, IMO. The price was nice too.

As far as efficiency goes, it’s been mostly colder weather driving and I can’t confirm the tires are more efficient than the pirellis. I can get 2.2mi/kwh in good conditions on the highway. My lifetime average is 1.8m/kwh, but that’s my wife driving around town and us going up hill to the mountains in cold weather.

good luck!

What speed would you say is your highway driving 70mph? 75? 85? trying to get an idea if

Now that I obsess about miles per kWh, I drive 70mph or less.

Caveat: most of the driving is done by my wife during the week shuttling our kid across Seattle twice a day to and from school. She spends 0% of her brain cycles obsessing about efficiency. I'm not sure she knows what I'm even talking about when I tell her about it.

Another note: I'm about to drive the fam from Seattle to South Lake Tahoe. We leave today, driving over two days. I will collect as much data as I can and report back how the car with the Nokian's performs.

Wow, that Nokian tire is 63 lbs, almost twice the weight of the Grabber. If your average is 1.8 mi/kwh then I’d say you are doing really well…at ~70 mph I’d guess it’s closer to 1.5-1.6…are you towing or doing a lot of offroading? If not, you could shed 23 lbs per tire and get closer to 2.3-2.4 mi/kwh with Defender/AS+3 Pirelli in 275/60R20 size (also bumping your range closer to 300 miles), something to consider…

It is the XL with 116 load rating and I am having discount tires install today. Will probably running at 48 psi like the 21". The 21" lasted 16k miles with 3/32 left. Will post pics and efficiency soon. Thanks again for the detail explanation

that’s awesome if you can get ~20 miles on flat ground running 70-75 that’s going to give you a good idea for average efficiency, hopefully it is around 2.6 or so

Anyone tried the Nokian Outpost nAT?

I do zero offroading and towing.

I got 2.2m/kwh driving freeway, mostly flat Seattle to Medford, OR going about 65mph. I got 1.7 Medford to South Lake Tahoe doing 70 often in high winds and over mountain passes.

I will definitely consider the tires you recommend.

Did I read elsewhere that changing the tire size means I need to have Rivian recalibrate cameras? Or does that only apply to changing wheel size?

 

[ksurfier]

If you have 275/65R20 then changing to 275/60R20 will result in 3% over estimated speed and efficiency. 2 mph and 0.1 mi/kwh adjustment to fix. I can’t imagine camera calibration would be needed, I’m sure they would try to sell it though. A half inch smaller tire isn’t going to change the geometry enough to matter, specially when the suspension changes by several inches depending on the setting.

Once again circling back. What is the stock 20 size? 275/60 or 275/65? And why would you choose that wasn't stock? The weight rating? Or is it the available tire options?

(Rivian won't calibrate a non OEM tire)

Rivian is very quickly becoming a "Worst offender" in terms of trying to "get you." We very quickly accepted the fact that they're selling software-gimped hardware and we barely talk about little things like this.

We're buying into the John Deere of trucks it's very quickly becoming apparent. Not happy about it.

21” and 22” rims OEM is 33” tire
20” rim OEM is 34” tire

Only 1 tire available for 21”

lot of people not happy with getting <20k miles for OEM options, specially when they are almost $500/tire.

33” inch tire on 20” rim makes for a lighter weight more efficient and more affordable tire, also many options available with 70k mile warranty. Most 20” OEM options are 55-64 pounds.

Internet quote:

“The Rivian R1S has a range of stock tire sizes, including 275/65R20 tires, 275/55R21 tires and 275/50R22 tires.”

I wouldn't say that. If you buy a tire that is the same size as stock there is no need to calibrate. I frankly don't care about the tiny deviation in the estimated range projections.

I chose the Pirell AS because they have the characteristics I am looking for (quiet, improved handling, range). They are well within the safe range for load.

I would. Rivian is a publicly traded company and is thus subject to the same forces of enshittification as everyone else. They've modeled themselves after the "profit darlings" Tesla on purpose, meaning we should expect any and all behavior from Tesla (minus Elon idiocy, so no rusting exteriors) to be replicated here. They're lining up their subscriptions, fees and servicing teeth and we're in the "good times" right now.

This is going to mean continued closed software development that will drastically limit modifications and completely hinder aftermarket support. Service? Forget about it. You're going to have to go to Rivian licensed places that are charged $500k for the pleasure of being that so in turn they're going to charge you $500 for a steering alignment.

These aren't going to be Jeeps. They're going to be iPhones. (I used the John Deere example, it's going to be almost exactly that)

I'm not sure how else to interpret, "you can only use the tires we tell you, you're not only on your own but your truck won't work right even though we only need to change 1 diameter value in one line of code we could easily give you access to via menu."

I moved from the Pirelli AS to the Michelin Defender LTX M/S2 when my Pirellis wore out. Really like the LTX M/S2. Used them in Tahoe this last week in a lot of snowy icy conditions and they worked like a champ. Really confident, solid, plowed through crud way better than my pirellis did last season.

Efficiency?

I hear what you are saying. But there is an equally rational and less nefarious interpretation of what Rivian is saying.

These are 7000 lb monsters with very complex electronic suspensions and safety systems. The company has carefully developed settings for these systems that are optimized around three tire options. There is no way for Rivian to account for all the many variables that go into tire construction across literally hundreds of other makes and specs of tires. It is not just about dimensions.

Rivian is not saying you can't use other tires. They are just saying that they are not in a position to recalibrate your settings to an unknown make of tire. If you choose to use non-OEM tires, it is at your own risk.

Whether one agrees with Rivian's choices or not (and I sure would prefer they calibrated my tire settings, all things being equal) they are quite understandable and rational. My guess is that the legal department had more to say in the matter than the marketing people.
