Researched the wheels on the green truck in the video. 20x9 with stock size 34" tires, but has a +1mm offset.

Just got mine on. 20x9, went with a 33 1/2" tire for a little more clearance and an 18+mm offset, so they stick out 0.66 inch less than the those on the green truck. Definitely happy with the fitment. Wasn't my first choice on styling as I normally go with all black, but, on the white truck, these are actually growing on me.

Do they rub at all? The ones in the video rubbed.

This would be a great winter wheel choice if it doesn't rub. Currently I have the 22s on order with hopes of finding 20s for winter.

The one's in the video are a +1mm offset, which brings the wheels out 17mm more than the set I have on. No rubbing with the set shown on the white truck. +18mm offset, The green truck went with stock 275/65/20 tires which are 34" circumference. The white truck wheels are 285/60/20 with a 33 1/2 circumference. Personally, I think they are more appropriately sized for the truck. The 34's dominate the wheel wheels. The 22's, assuming stock tires, will be 33" tires, which I think is much more proportionate for the size of the truck. Between the less offset and slightly smaller tire diameter, happy to report no rubbing. .

Not a huge fan of this design but 20x9 with a +30 offse.

With this tire, the size difference is so minimal it would barely affect the speedo.

My delivery specialist said to contact Rivian support if I ever change tire sizes so that they could adjust the speedometer. I don’t know if they’d still do that for non Rvuan-acquired wheels/tires.

 

[Wing]

Yeah, no.

Not going to contact them every spring and fall. The difference here is at 60mph indicated actual 62mph. It's fine.

Currently my tires on my LX are like 5mph I just remember this and adjust in my head.

Too bad the factory speedo is already off by 3mph! 73mph on my 21" roads are really 70mph... I've verified this by third party GPS, Posted road sign speed gun and police officer...

 

[BrianGoodwin]

Funny that folks assume stock is accurate for speedo and rarely is that the case, particularly when the factory has three different wheel offerings. We pick up our truck with stock 21 inch this week and will curious to see if mine also does 70mph actual at indicated 73mph. That would mean going a little taller would actually make the speedo more accurate....perfect.

Actually, that tire size is a full 1 inch less diameter. 33" vs 34", at least for the All-Terrains. If you have stock 21's or 22's, then you are correct, it's basically the same size. Just depends on what your truck came/comes with.

I just received a set of 275/60/20 Pirelli All-Terrains. They're not technically designed for the Rivian, but have the exact same tread patter. On Tire Rack, the 275/65/20 Rivian designated tires are $394. The 275/60/20, same tire name/brand/appearance is $248. Nearly $150 less per tire. Mine came with the 20" All-Terrains. Once I get the new one's on, I will be calling Rivian to update the Truck. I have a tire that's 33 1/2" right now and my speedo is off by 5 MPH! Will probably be closer to 7 or 8 MPH with 33" tires. Not going to live with that big of a difference. Rivian speedo is already off by 3 MPH as it is, which is too much.

Pirelli 275/60/20 from Tire Rack at $248.50. Opposite side is not white letter.

I'm betting they can "reprogram" is just that they can update your system to be 33s or 34s. When you go into the info on thr screen it tells you what tires you have. They jist change that.

You don't need to guess just plop tire sizes into here:

275/65-R20 tires are 1.08 inches (27.5 mm) larger in diameter than 275/60-R20 tires and the speedometer difference is 3.2%

There is a place in the truck to put in tire size??? I couldn't find it. Will have to look again if it is there. That would be much, much, much easier, like the Tesla is.

And there is the problem. There are wheels available with less offset, BUT, so far, at least the ones I've found, none have had an attractive style. Have searched, researched and searched again. Get to a 20mm offset and then several options start coming available in Rivian's odd bolt pattern (for a truck). Between those and going with at 275/60/20 (33" tire), I think will be a good option that "shouldn't" have any rubbing issues. I'm at 18mm with 285/60/20 (33 1/2 tire) and no rubbing. Wouldn't want to run it in its lowest setting though. I don't like that setting with any wheel and tire. Bottoms out the suspension and makes for a fairly jolting ride anytime you hit a dip as there's now downward travel left in that setting. Even the "low" setting is borderline. Plus, it's a truck. For those seeking a "sport truck" instead of an off-road style truck, then OK, I get lowering it. But, for those with the 34" all-terrain tires, it just looks silly having it in the low or lowest settings. IMHO of course!

Under vehicle info but it's not something you can change

I just called Rivian and told them I purchased a stock set of 21's for it and asked them to push an update to the truck to correct the wheel size, notifying them that the speedo is now 7-8 MPH off.

As noted above, I actually have 33 1/2 tires on it. Being that the Rivian is already off by 3 MPH with the correct settings, thinking that it might actually be spot on if they update the truck to say it has the stock 21's (33") tires. So, the 285/60/20's could be a very good replacement size for the truck to get the speedo to actually read correctly.

Being that it's quite common for truck owners to change wheels and tires, I'm sure they'll get tired of having to constantly take these calls and will eventually make it a configurable option from inside the truck, as Tesla does. Kind of a waste of their time to have to contact them to make the change for you. Especially for those in winter climates that may change out their wheels / tires twice a year.

They do? When I put wider tires on the Model 3 which made the speedo off by 3 mph, Tesla would not adjust it. Said they only adjusted when using the Tesla wheels and tires.

Allowing people to understate the mileage on the car would be an issue with self adjustment.

I can't say 1,000 percent on the Model 3 as I only had mine for 2 months, but for certain in the Model S, you can go into the service menus and select which wheels and tires you have on the car. The Model 3, there are only 2 choices, so it's possible they didn't include it in that software, but if they did, would be in the "service" portion of the menus. In any case however, you can only select from Tesla offered wheels / tires. So, no you can't simply go enter in your tire size. In the case of the Rivian, they offer a 34" tire and a 33" tire. Naturally, the difference have a big impact on the speedo. But as of now, you have to go through Rivian to select one of their three options.

Had a great chat with a fellow from Variant about their wheels for Rivian. Super friendly and helpful, seriously considering a set.

Love that more and more forged wheel makers are jumping into the Rivian Application!

 

[eHauler]

Those wheels really complement the R1T's design, enough that it could easily pass off as a factory wheel option.
