Discontinuation of 21” wheels

[Ngkgb]

What happens to all of us with the 21” wheels since they are being discontinued? Do we have any third party options as of now?

Third party what…tires? Rivian doesn’t make tires. The ones you have now are third party and I assume will continue to be available.

Yea. I meant tires. Is the Michelin Defender the closest match? I don’t see many options.

Unless another manufacturer makes a vehicle with 21s, you will probably be limited to the couple tire choices (Pirelli, Michelin) available now. Worst case scenario you would need to switch wheel sizes and get some similar AS tires.

I’m betting pirelli continues to make the 21” verde, but prices are not going down. It would be nice if Rivian offered some official guidance for us folks with the 21” option.

As a point of reference, the i3 has some very specific skinny tires in a non square set. I’m not aware of any vehicle that uses those tires/wheels. The entire vehicle was discontinued by BMW several years ago but you can still buy the tires.

I’m confused how the 22” wheels are more efficient than the current 21” wheels?

While it's not a super common size, there should always be 21" tires available. Rivian is not the only OEM that uses a 21" wheel. Our Grand Cherokee uses a 21" rim and comes with contenential tires.

wheel size does not equal tire size... your grand cherokeee tire is not the same size tire as the rivian.

Just adding in case it was missed, Michelin is supposedly releasing the Defender LTX M/S2 tire that will fit the Rivian 21". Suppose to have been next month, now it's moved to the fall.

I had another vehicle with OEM tires in a very unique size. Yokohama kept making the tires for a long time. I'd expect Rivian probably has an agreement for Pirelli to make the tires for 10 years or similar.

I think that once the 21" tires are introduced by Michelin this fall, they will be available from then on. I am hoping that these will be a better and less expensive option that the 21" Pirellis.

It'll give me a reason to tell my other half, that I need to upgrade to a new wheel size and tire. LOL

I guess I'm confused why people would think it's anything other than better?

Rolling resistance depends heavily depends on the elastic hysteresis of the material. Steel and aluminum have much less hysteresis and thus result in lower rolling resistance, so the less rubber the better the rolling resistance, trains don't have rubber, and that's a huge reason why.

Also rims can be formed to more precise shapes than rubber which could theoretically improve efficency.

Why would more rubber improve things?

it was always the worst choice due to its unique size. those that got the 21s took a risk and unfortunately, its become even worse.
