Well, I prefer to not let the facts get in the way of my reality. JK! I really do remember something that pointed to 116, but maybe I got it backwards and one of the websites said 116 but it's actually 115. Meh.

Maybe pointing this out would help with those trying to get 115 load tires?

It remains weird to me that they put the lowest load index tires on the thinnest sidewall OEM tires.

I think mid last year they started selling the 22" 116 tires. Rivian replaced two of mine with 115 after this change already happened, but tire rack looks to have stopped carrying the 115. I am guessing they switched to 116 going forward but Pirelli had to get rid of all their old stock. Still, I personally would be okay with running 115 but I wouldn't tow with a loaded bed as well.

That makes a lot more sense.

I don't have my Rivian yet, but I'm very tempted to run these in the summer, but I never plan on towing:

The slightly smaller diameter and higher grip should get the max 0-60 time. Maybe it could actually beat my model 3 performance (until the Rivian reaches it's now lower top speed.)

Those show as 113 load rating...so that may be an issue.

I just called Tire Rack to ask about their inventory on these wheels - I was told that they have many more orders placed than they have wheels coming in soon, and the restocking dates on the website are just a best guess. It could be January before they're available. But I was also told something else a bit more concerning. I have the stock 21" wheels on my R1S but need winter tires, so I was hoping to put a 275/60R20 winter tire on these wheels so I don't have to have the speedometer reprogrammed. But the guy at Tire Rack said that they couldn't sell me the Bridgestone Blizzak DM-V2 in that size (the only winter tire in that size they carry, apparently) because the 115 load rating is too low! Does this make sense to any of you? He said you have to build in a 10% margin for SUVs *and* deduct 10% from the tire's rating, but even then it looks to me as if it should work. But he said it was about 600lbs. short per axle and wanted me to get 275/65R20 tires instead.

I'm no tire expert, but as far as I can tell, a load index of 115 translates to a weight limit of 2,679 lbs. per tire. The R1S has a GVWR of 8,532 lbs. Even if I decrease the tire's weight limit by 10% to 2,411 lbs. per tire, *and* increase the GVWR by 10% to 9,385.2 lbs., the total tire weight capacity for four tires is 9,644 lbs. - more than 250 lbs. over what I'd need, right? Am I just doing it wrong, or can I really put a 115-rated 275/60R20 tire on these wheels and still be okay?

You are right. I had to call tire rack a few times because they also wouldn’t sell me the X ice snows in 275/60R20 115 initially because of the load rating until i found documentation that earlier rivian shipped with 115 SL tires. they reviewed it and came to the conclusion it was safe and allowed me to buy them.

they also claimed not to have the correct TPMS sensors when you configure a wheel and tire package on their website however talking with them on the phone revealed they actually do have the right sensors. at the end of the day they did sell me a set of wheels with the x-ice snow SUV tires mounted and balanced and Tpms installed.

Yes certainly. 113 is high enough to cover the max GAWR, but it's less than what most shops will allow 115/116.

You might find a 113 tire has too low a max pressure rating too. So while it might technically be able to handle the weight, it might be at a lower PSI than you would like to run, which could affect handling.

Personally I’d not run a 113.

Tire rack shipped my KO2 at their max inflation pressure of 80 PSI. I have been running them at 60 because it feels like a good compromise. Probably still a month or so away from being able to measure a difference in tire wear.

I was thinking about your situation when I was looking at the Load Index vs Load Range. As you go up the load range (SL, XL, C, E, etc.) they max load pressure increases as well. But it looks like there are two types for E, one has a max load rating at 80 PSI and the other was like 50 PSI. So, in order to get the reported load index of the tire, you need to run it at the max load rate pressure or higher. I suspect the tires you selected have a very high load index, but I think the rating is linear relative to the air pressure. So, you might need to make sure you keep you PSI high enough as a % of 80 psi to ensure the carrying capacity is above the load index of 116.

Load capacity of load index 116 = 2756 pounds
Load capacity of load index of other tires ={P} pounds
Min tire pressure to meet the same capacity of 116 = 80 * 2756 / {P}

Side note, the SL tires are max load carrying capacity at 35 psi. And many of them have a max PSI of ~50. And the XL tires are max load carrying capacity at 42 psi. It seems the main advantage of the XL tires is just that they are supposedly tougher.

My 2022 6XXX VIN R1T shipped with 115’s... and I just had Discount Tire put on new Continental H/T 115’s. The new tires were delivered via TireRack (DT’s sister company) and even though the Continental’s didn’t populate in DT’s compatible tire list for the Rivian, they put them on anyways. I’m sure it helped that my stock tires said 115 on them.

BTW, loving the new tires. Equally as quiet and grounded as the stock Pirelli’s… but with better tread depth.

Just following up to share the end (hopefully) of my experience.

I ordered and received the Radius WI35 from TireRack in early October, and ordered Blizzaks (LT275/65R20) from Costco at the same time.

Made an appointment for yesterday for installation when I made the order. At the time it was the furthest out I could book an appointment at Costco tire, and I planned to push it out until closer to Thanksgiving (typically the "ideal" time to put show tires on around here, and when we have our first winter road trip planned), but forgot until it was too late and the tire center was fully booked up for the rest of the month.

So, I went in to the Costco tire center (in Clarkston, WA) yesterday with:

• Radius WI35 Wheels from TireRack
• Bridgestone Blizzak LT275/65R20s from Costco (Delivered direct to the tire center)
• RDE232V26 - BH SENS OE Direct-Fit 433MHz OE TPMS Sensors from Amazon
• 4x EV Jack Pucks from EV Sportline

This Costco tire center is well run, and easy to deal with. Used to dealing with lifted vehicles and unusual fitments. The manager who checked me in mentioned that they had Tesla pucks, but not Rivian ones. He also refunded me the $8 disposal fee that's automatic with online orders (Woo!) since I was keeping my OEM tires that only have 6K miles on them. The tech I talked with later said they'd had one R1T in for a tire rotation, but this was the first mount and balance they'd done on a Rivian.

They got our R1S on the lift right when my appointment started. They estimated an hour-and-a-half, it ended up taking 2.5 hours.

The tech was honestly fantastic, but called me because:

• They didn't know how to turn the vehicle "off" (I told him about the wheel change menu, he said with Teslas they just take the key into the showroom and that does it)
• The doors kept locking (this was totally my bad, I forgot about the appointment until last minute, and couldn't get the fob from my wife in time, so had to give him the wristband. It didn't work very well, and I came back twice with my phone to unlock things for him)
• He couldn't fit all the summer wheels and tires in without taking out the car seat in the middle row to fold down those seats, and wanted to make sure I was OK with that.

All in all, a good experience considering this was their first Rivian mount and balance. It would be really nice if Rivian had some kind of printout/instructions for tire shops not familiar with the vehicle.

If I was doing it again, I'd:

• Be prepped with the key fob.
• Make sure I had lug nuts (Tire Rack included them with my order, but I hadn't checked, and when the manager asked if they were in the boxes with the wheels, I had to say, "I hope so?")
• Fold down the back and middle rows
• Let the manager/tech know about the wheel change mode

The wheels look good, maybe not quite as good as the factory 20", but for $3K less than a 2nd set of those, I'm quite happy. Some of the Method's might look a bit better for my tastes, but these are just fine, and I didn't want to take any chances with offset/fitment.

I kept an eye on my TPMS on the way home, and it took about 10-minutes of driving to get the new wheels to register and start showing their pressures on the infotainment screen. No complaints or warnings from the vehicle.

I'll re-torque the lugs here this afternoon - though not 100% sure my torque wrench goes up to 140 ft lbs. If not, I'll top by a local tire shop and ask them to do it.

Finally, obviously (since these are awfully close to OEM diameter/width) no issues with rubbing, even on low. Hopefully we don't get any particularly warm spells in the next couple weeks, since those are particularly hard on Blizzaks even on normal-weight cars. I imagine that'd be hell on their tread life with the weight of the Rivian.

I plan to swap back to the summer tires in the spring myself (like I do with our other vehicles), we'll see how that goes then.

Just spoke with Tire Rack while I swapped my Radius order to MSW.
1. If anyone wants black Radius wheels, they now have 4 new ones to order. Ready Set GO!
2. They wouldn't mount either wheel to the 115T rated snow tires because they are 116 in the system for all three OE Rivian load ratings. No luck talking them into the original 115 22" load rating. Has anyone had luck convincing them online to mount 115s?

Thanks!

Edit @Smeek and @dilettanti Saw your earlier posts regarding 115 winter tires. if you have any contact that worked there or advice on what they reviewed to okay mounting them that would be helpful! Thank you

I had the 115 load rating Michelin snow tires mounted on my 22s. However I had the wheels off the car and brought them in (wasn’t ready for winter season yet). They did ask which car it was for and I told them..no push back.

Which MSW wheels did you get?
