Chevrolet Silverado EV tires
The Chevrolet Silverado EV leaves the factory on 265/70 R18 and 275/50 R22 and 275/50 R24 and 285/75 R18 depending on wheel size, and the 265/70 R18 124S LT below is the one most owners are replacing. The GMC Sierra EV 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
Every Silverado EV fitment is an LT (light truck) tire in load range E. The load index given here is the single-fitment figure Michelin lists. A passenger-construction tire in the same dimensions is not a substitute.
Pressures are high and they differ by axle. The 24 inch RST label reads 61 psi front and 68 psi rear, and the 22 inch LT goes to 68 psi front and 75 psi rear.
The 2026 Trail Boss has the largest and strongest size, LT285/75R18 at 129S, which is 1,850kg per tire. The 22 inch is the lightest-rated fitment at 119, and that is still 1,360kg.
S is the speed rating on every size, 180km/h, which shows that these tires were chosen to carry load rather than for speed.
No tires listed against this fitment yet. Product specifications are published from each manufacturer's own data and that work is not finished for 265/70 R18. 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 Chevrolet Silverado EV take?
- It runs 265/70 R18 and 275/50 R22 and 275/50 R24 and 285/75 R18. 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 Silverado EV?
- Only at 265/70 R18 124S LT 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.
- Do I need the LT265/70R18 load range E marking?
- Not legally. The LT265/70R18 load range E version can carry a different compound or an acoustic foam liner that the same tread pattern in the shops does not, so if the car is quiet now and you fit the unmarked version, expect to notice.
