22's vs. 20's - In depth discussion.

[SACDFJC]

Does anyone have any info on what the 21 or 22 wheels weigh? We know from some on here that the 20” AT wheel/tire weighs 89 lbs, per Pirelli the tire is 48 so the wheel is ~41 lbs. My guess is the 21 & 22 will be heavier due to being cast & larger.

I weighed a 21 yesterday. 81# for tire and wheel combo without aero covers.

Interesting...thanks for the info. I was guess 45 lbs for the wheel. So if you got 81 lbs, tire rack states that tire weights 37 so ~44 lbs for the wheel and cover, that's pretty good.

So now I'm really thinking of sticking with the 20" wheel. This way I can see how the A/T performs as this is really a hybrid tire and not a true A/T. At replacement time, more than likely I would put on a Michelin Defender LTX M/S. This package would give me a Forged wheel at 41 lbs + 42 lbs for the tire for a total of 83 lbs and almost the same outer diameter of the 21" set up with I think a much cheaper and better overall tire. Just my 2 cents...

20" w/AT: 41 lbs wheel + 48 lbs tire = 89 lbs combo
21" AS: 44 lbs wheel + 37 lbs tire = 81 lbs combo
22" Zero's: ? 46 lbs wheel (does anyone know) + 37 lbs tire = ~ 83 lbs combo
20" w/LTX: 41 lbs wheel + 42 lbs tire + 83 lbs combo

Great points so far with the weights. Should improve range with the defenders as well. Does anyone know how much better it is to have forged vs casted rims? I know better rigidity but how much? Also what about corrosion other factors. This is turning out to be a very informative thread. Thanks all for the contribution

From a “deal” standpoint, the 20s are better deal in dark since both cost the same to us but likely Cost Rivian to purchase

Forged rims are typically twice as expensive vs cast rims. The forging process is expensive and more costly than casting. The largest advantage of forged is they are usually 20-25% lighter with the same or better strength. I would expect all of the Rivian rims are very capable and strong. I would also assume all are aluminum alloy and thus corrosion resistant. For me personally, I love the look of say, the Dark 22's, love the range/efficiency people are seeing with the 21's, but I keep coming back to I think the best overall would be the 20's with a 275/60/20 vs the 65 series that Rivian landed on. I think it will get close to the 21's range, and say with the Michelin LTX better wear and a great overall tire package.

OP has me thinkin…

Agreed with some other posts. I think the 20s just suit the overall look of the R1T and R1S. The first drive I went on was with the 20's. Handling was solid, not exactly on par with my MYP, but honestly not far off. Whatever depending / anti roll measures Rivian is using is pretty amazing for the size and weight of the truck.

My personal fav is the 20 inch dark wheels. In person the black chrome looks very dimensional. Also in SoCal purely esthetic choice atm, but im hoping it will motivate more camping and off roading.

All-weather (not all season) tires are fantastic at snow, ice, and rain. Most people should get these instead of snow tires. Michelin cross-climates are fantastic, goodyear weatherready also good

Love the cross climate tires. I have them on my Polestar and my wife’s XC90.

Exactly the same feel as your first statement.
Can you expand a bit on the Michelin LTX tires? I don't know my tires very well but it sounds like they will provide lower rolling resistance than the stock 20's so better range? Is there a load rating concern with them?
I think if there is a good alternative to the tires that come with the 20" wheels that improve range, then I will definitely go with the 20's and look longingly at the 22's lol

The specific model I'm thinking of is the Michelin Defender LTX M/S in a 275/60/20 with a load rating of 115T. I've had a couple of sets of LTXs over the years. This is the latest version from Michelin as they continue to evolve this tire. Load rating: in my conversations with TireRack, for the R1s, a tire must have a minimum load rating of 115. For some reason, depending on the size you are searching for, TireRack's website will show tires for the R1's that do not meet the load rating. With information from Michelin, my personal experience, and data from Consumer Reports, this tire is rated very well in many aspects, but keep in mind, for any tire, there are compromises manufacturers have to make and thus no tire is perfect for all situations.

For me, in consideration of the long term with the R1T and its possibility of eating through tires with a weight of over 7,100 lbs is why I'm thinking a lot about tires. I think going down to the 60 series gets you a little less sidewall vs the 65 (ie, better handling?), more of a road tire but still plenty capable for rain, snow, dry, lite off-road, etc., My guess and I hope some engineers chime in, improved range over the stock 20" A/T and maybe close to the 21". The LTX package will be a 6 lbs reduction in weight which I think is pretty significant, and a reduction of 1" in overall circumference which is also a plus. There is also the $$ factor. The stock A/T are close to $400, the 21" are $415 each, while the LTX is $285 and should easily outlast any of the stock tires.

My first drive was on 22s. I was impressed with their street handling. My current configuration, though, is for the 20s as they are forged. I'll probably pickup a set of forged 22s for most of my driving and use the 20s for winter and any more serious offroading.

Another option would be to pick up a second set of 20s and run 275/60R20 street tires.

Car and Driver just put up an article claiming their test at steady 75 mph on the 22 inch wheels got 60 more miles of range than their test with the 20 inch all terrains on the R1T (280 vs 220 miles). If thats accurate id reconsider the 20s vs 22s.. Link to article below.

Alex on Auto got 338 miles on the 21”. Decision’s decisions ?‍

Every Car and Driver article about EVs upsets me. They either demonstrate more ignorance than the average EV owner or act like they are on a personal mission to convince nobody to buy them.

I get my truck on Friday and have it coming with the 22's.

I did my config so long ago - and with all the delays forgot about it - and figured I could make a change once they were ready to do my build. When I spoke with my guide, changing my config from 22's to 20's would have slowed my delivery considerably (and didn't want anything slowing it).

I live in NJ and very rarely off-road. Re snow, I've never had a capable truck like this, and never was prevented from going anywhere in snow. We are avid skiers and often chasing snow in VT and never had an issue. Granted, if I lived in the Mountain West - WY, MO, CO, etc - I would get the 20's w beefy AT's.

Cant wait to get my truck and eager to see what tires on it.

Are you actually finding a shop willing to mount those? Some are hassling people over not having an H rating (even though the trucks are limited to 110, below what a T would be able to do.) Also it seems silly 'minimum' load would be 115, since that correlates to roughly 10,500lbs on a vehicle that is specced at 8500 fully loaded.

For what it's worth I did some looking and if you can drop to a 275/55 tire size it's actually extremely common on 20s and there were a lot of 117H or higher options available, I may end up doing that when I wear mine down.
