Efficiency values are distance-weighted averages from real owner drives, excluding towing sessions. Your results will vary with driving style, speed, weather, and vehicle configuration.

This guide improves as more owners identify their exact tire.

R2 tire sizes: 20 vs. 21-inch wheels

Rivian lists these two R2 wheel and tire packages in its Gear Shop:

Use the comparison above to see measured efficiency for each tire with qualifying R2 driving data. OEM marks an original-equipment tire in Roamer's catalog. The list grows as owners contribute driving data; it is not a complete list of compatible replacement tires.

Which R2 tires are most efficient?

The comparison ranks tires by observed efficiency, with vehicle counts and tracked distance beside each result. Higher mi/kWh means more distance for the same energy. Check the sample size as well as the ranking: a result from one vehicle tells you less about the wider fleet than a result from many vehicles.

How much range do all-terrain tires cost?

These results show what different R2 owners achieved. They do not isolate the effect of changing tires on the same vehicle. Weather, speed, routes, vehicle configuration and driving style can explain differences between averages. A small gap between the 20-inch and 21-inch results is not a measured range penalty from the tires alone.

How Roamer measures R2 tire efficiency

Roamer combines qualifying tracked drives from participating owners who share community data. Each drive is associated with a recorded wheel and tire configuration. Efficiency is the total distance divided by total energy consumed across those drives. Longer drives contribute more distance and energy to the result.

The main figures exclude towing. Where enough towing drives are available, towing efficiency appears separately. R2 results are kept separate from R1T and R1S results. Vehicle counts identify distinct contributing vehicles; a vehicle that has used multiple tires can contribute to more than one row.

The comparison updates as driving data is processed, with results cached for up to six hours. An absent tire means Roamer does not yet have qualifying data to display, not that the tire is incompatible or inefficient.

Where do the tire details come from?

Efficiency figures come from Roamer's owner driving data. The tire catalog draws on the RivianTrackr Tire Guide. The wheel sizes above link directly to Rivian's specifications.
