At the 113 you are still just over 10k GVWR (2535 lbs x4). Should be just fine unless you are regularly hauling something in the >2.5k lb range

Well, here you will be in a problem - 113 is below the required load, and if something happens - you may have a liability.
There is a calculation you can find on the net, how much each tire must hold for a GVWR. For Rivian weight, you will find that the minimum allowed is 115.

Said that I see some people using 113 (and you can find 275/50/21 tires with 113 load rating) - but everyone can take their own risks...

You also will have some issue with speedometer due to size change:

Where does it state a required tire load? With 113’s you are not lowering the GVWR as still well above the trucks GVWR of ~8500 lbs.

I need to find the requirement, the difference is 880 lbs overall for 4 tires. I think there was something related to what happened when 1 tire goes off.

But the main problem is liability - and that is why non of the big brands will install this tire on Rivian. You can DYI, or find some small shop to do this for you.

For the one tire goes out scenario, #3 115 load tires (~8k lbs) is under GVWR of ~8500 lbs.

Correct, and that is why 115H tires are shown as compatible and 22" were 115H in the beginning. Rivian changed this to 116 later.

116 is still under GVWR (~8200). Have to go to a 118

Look, it is a bit more complicated I guess, some helpful information:

Understanding Tire Load Ratings

People have been riding on air since John Dunlop invented the pneumatic tire in 1887. The average motorist might think that his tires’ rubber and steel belts su

Regardless, what really matters for liability, is what the vendor is stating - in our case 116 (or kind of 115 for 22" that eventually became 116).

Will 113 work if you do not tow and load the truck a lot - I think yes. Will it be Kosher - probably not

Remember, when you increase the diameter of your wheels it affects your speedometer! To make it clear if a car (any car that had 15" wheels) and you increase the diameter to say 20" 1 rotation will get you farther (and use more energy "Drag Coefficient) so besides the tires you've increased the load that the output shaft was designed for and you'll need to have the Speedometer recalibrated!

Where's the rest of the car?

It’s a 800hp >7000 lb truck. It will eat tires no matter what. If you really want longer tire life could go to a 10 ply LT but the trade off is ride quality will go to crap. When my wife had a cayenne turbo she went through her first set of tires before the first oil change…. We had it for 3 years and put 3 sets of tires on it.

I have driven trucks over 9 & 10,000 pounds and gotten 30,000 miles wear. 10 Ply load range E 2850 # capacity single weel, not dual. Ok they were often 16", but wouldn't that cause faster wear, not less wear?

 

[DC1430]

I have 7000 miles on my Pirelli ATs, wearing ok, but have not thought about the replacement cost yet. $1863 on Tire Rack? Gezzz. Thats a fair more then a set of Pilot Sport 4S tires for my 911.

 

[gregchick0]

The tire design is likely just as soft, but the weight capacity much higher on the R1T. I too have had a couple Carrera's, the tires got 20,000 miles at best. They were $500 each out the door. I would be glad to deal with a different ride and some noise and get say, 30,000 or more mileage.

 

[paulcoble4827]

Yeah, I get that. I also had a lot of Tesla's and usually got at least 25k out of them. But at the rate I'm eating up these tires, it seems I won't even get 20k out of them.

I'm looking at the Americ'a Tire website and seeing three models of Pirelli tires -- none the Scorpians that come stock from Rivian -- that are all weather tires and with 60,000 warranty.

I realize, though, that your post is several months old. Hopefully you solved this for yourself already.

Aw crud. Looked back again at their site. They showed me other Pirellis with a small notation above that said they don't fit the Rivian, and Scorpions . . . with no warranted and costing much more . . . are all they have for the R1S.

Sorry for the brief misdirection.

 

[gregchick0]

The issue is weight and tire material, I think Pirelli design serves a quiet tire that has traction control on ice and all weather along with weight.
I wish the mileage issue was served.

Aw crud, no worries, words matter, tires are so complex.

My Pirelli tires are at 2 after 21,000 miles. I have a 2021 bronco sport. I have had the vehicle for 2 years under a lease. Seems these tires should be covered under warranty.

"@2" I guess 2MM or @ the wear bar. Not bad for the wear I know about. That is better than par. Your Bronco is an entirely different vehicle. I had a Honda CRV AWD that had 60 K on the tires and still over 3MM.

Re: "Pirelli's crappy warranty"
If you buy that same set of 4 Pirelli Rivian tires from a tire dealer and have them installed, those 4 replacement tires ARE covered by the warranty. 50,000 miles in this case. There have been many posts from many EV owners (including Rivian owners) who have had no problems getting a warranty credit for Pirelli tires if they wear out in less than 50k miles - again with the caveat that we're not talking about the tires that came with the car, but with tires purchased from an authorized Pirelli dealer as replacements. Pirellis are used on many EVs, and many other performance vehicles, and they honor their warranty.

Unfortunately I found out that Pirelli is not honoring their warranty through Discount Tires. I purchased new tires in July last year, 12k miles later and the tread depth is below the level that discount won't even rotate them for me. They also don't have any other tires for the 21" rims so I guess we have to keep buying these tires. Hopefully they start designing some tires that hold up better or have a deeper tread so they last longer

 

[O. horridus]

Um, what did Discount Tire have to say about that? Not every tire has a treadlife warranty (true of every tire manufacturer). But if it's advertised on the Discount Tire website as having a warranty then they should honor that.

They were surprised too because most of their tires have warranties, so they had a manager investigate and he said in their system, none of the tires for Rivian in any of the rim sizes have warranties. They have other Pirelli tires that have warranties, but those specific ones that fit Rivian don't have them for treadwear. Looks like they know how quickly we're going through them and so they wont give them a warranty.

Pretty disappointing.

I wish several things:

• That 21" wasn't the standard, we have to pay more to get rims that companies already make tires for
• That the standard tires had a higher tread depth. Most I've seen online are like 12-15/32 and ours are 10/32. So in addition to wearing them out faster, we're also starting with less tread

Actually the Pirelli tire comes close to 9/32" tread depth. Agreed, we have a problem Huston.
