Rivian R1T tires
,_front_6.21.22.jpg){kind=link}
The Rivian R1T leaves the factory on 275/50 R22 and 275/55 R21 and 275/60 R20 and 275/65 R20 depending on wheel size, and the 275/65 R20 116H below is the one most owners are replacing. A standard load 116 rating is modest for an electric car and says something about where this one's curb weight sits.

Your own placard is the authority. You will find it on the on the driver's door jamb, on the B-pillar. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tire.
What changes on this car
On 22 inch wheels Michelin has listed an HL (high load) 275/50 R22 116H since 2023, a construction above XL. It sat alongside the original 115H XL until 2026, when only the HL remains. A 115 XL is under-rated for any R1T whose label says HL 116.
The all-terrain 275/65 R20 has about 179mm of sidewall, the deepest of the four sizes, and still reaches 116 at standard load.
Every size is square and inflated to 48 psi, so the only choice is the wheel. The 2025 all-season 20 inch, 275/60 R20 115H, has the lowest index on the truck, at 1,215kg.
Three of the four sizes reach 116, which is 1,250kg per tire, on a truck rated to tow up to 11,000lb.
No tires listed against this fitment yet. Product specifications are published from each manufacturer's own data and that work is not finished for 275/65 R20. Match or exceed every figure in the table above and you cannot go far wrong.

Every figure here comes from one tire maker's own fitment data, checked across different years or trims. That is a second look rather than a second opinion, so check the label on your door jamb before you buy.

Common questions
- What size tires does the Rivian R1T take?
- It runs 275/50 R22 and 275/55 R21 and 275/60 R20 and 275/65 R20. The exact fitment for your car is on On the driver's door jamb, on the B-pillar.
- Can I fit a cheaper tire to a Rivian R1T?
- Only at 275/65 R20 116H or better. That is the figure to hold: a tire below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
