After integrating with Chad’s excellent Rivian Roamer tool, I’ve been able to connect real-world tire efficiency across a wide range of Rivians into my incredible Tire Guide. When you remove outliers with data from only a single vehicle, the top choices for each wheel size become clear. The same few tire models consistently perform well, and honestly, the factory tires are much better than most, including myself, tend to believe.
Quick heads up before we get into it. This one is R1 only, so R1T and R1S. We are leaving R2 out for now because those are still too new and there just are not enough real miles yet to trust the numbers. Once that changes, I’ll fold them in.
And on where these numbers come from. Everything here is pulled from actual owner drives through Rivian Roamer, measured in miles per kWh, so higher is better: more range out of the same battery. Thing is, a tire can look amazing when exactly one vehicle is feeding it data, so we cut anything running on a single vehicle and stuck with tires that had a real group behind them. That alone shuffles the board quite a bit, and it is the fair way to read it.
Most efficient 20 inch Rivian tires
Top 5 by real-world efficiency, R1T and R1S, single-vehicle results removed.
Most efficient 21 inch Rivian tires
Ranked by real-world efficiency, R1T and R1S. Only four tires have a solid multi-vehicle sample.
Most efficient 22 inch Rivian tires
Top 5 by real-world efficiency, R1T and R1S, single-vehicle results removed.
If there is one thing to walk away with, it is that this guide rewards patience over hype. The flashy single-vehicle numbers will tug at you every time, but the tires with hundreds of vehicles and real miles behind them are the ones that will actually hold their range for as long as you own the thing. Right now that puts the factory tires in a genuinely good spot, and if you are shopping aftermarket, the Hankook iON HT and Michelin Defender LTX M/S 2 belong on just about any shortlist. The more owners that plug into Rivian Roamer, the sharper all of this gets, and those one-vehicle outliers will sort themselves out.
Any data on the 20″? you have the 22″ twice!
Oops, should be fixed now!
Fixed. Thanks!
Nice read, but I think you doubled up on the 22’s and missed the 20’s
Oops, should be fixed now!
Did you mean to show the 20″ tires? You have the 22″ listed twice!
Oops, should be fixed now!
Jose, Nice piece. Note that when taking delivery of ’26 R1S/G2/LE, the wheels are actually 22″ Michelin Pilot Sport 5S street tires. However, the vehicle recorded them as 20″ Pirelli Scorpion MS (All Terrain). Back in late ’25, we could not access 22″ Michelin Pilot Sport 22″ Now we can. The data, at least for the 22″ LE could be wrong. . .
Ah yes, the Quad does have the ability to come with the Super Sport tires. I can ping Chad about it to ensure accuracy.
Great info! Now we need a list like this about road noise. I got a loaner for a few days when my Michelin equipped car was getting fixed. I don’t know which tires were on it, but it practically screamed at freeway speeds. I kept feeling like I was in an ICE that desperately needed to upshift.
