Chevrolet Blazer EV tires
The Chevrolet Blazer EV leaves the factory on 255/60 R19 and 275/40 R22 and 275/45 R21 depending on wheel size, and the 255/60 R19 109H below is the one most owners are replacing. A standard load 109 rating is modest for an electric car and says something about where this one's curb weight sits. The Honda Prologue takes the same size.

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
The load indices sit in a narrow band, 107 to 109, but the construction changes with the wheel. The 19 and 21 inch tires are standard load. The 22 inch is XL.
The SS has its own speed rating on the 22 inch, 107V against the H listed for LT and RS on the same wheel. An H-rated replacement is not enough for an SS.
The base 19 inch 255/60 R19 109H has the highest rating of any Blazer EV fitment, 1,030kg per tire, along with the deepest sidewall at about 153mm.
Placard pressures depend on the wheel: 42 psi all round on the 19 inch, 38 psi all round on the 21 inch, and on the 22 inch 38 psi front with 42 psi rear.
No tires listed against this fitment yet. Product specifications are published from each manufacturer's own data and that work is not finished for 255/60 R19. Match or exceed every figure in the table above and you cannot go far wrong.

Common questions
- What size tires does the Chevrolet Blazer EV take?
- It runs 255/60 R19 and 275/40 R22 and 275/45 R21. 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 Chevrolet Blazer EV?
- Only at 255/60 R19 109H 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.
