2024+ Chevrolet Blazer EV 19" OEM Tire Replacement Guide

The 2024+ Chevrolet Blazer EV LT ships on a 19×8.5” alloy wheel with a factory 255/60R19 Bridgestone Alenza A/S 02. The RS trim uses a larger 21-inch wheel covered in our Blazer EV 21” OEM tire replacement guide. The high-performance SS uses a 22-inch wheel covered in our Blazer EV SS 22” OEM tire replacement guide.

OEM Wheel and Tire Specs

The LT trim ships on a 19×8.5” wheel at +37mm offset, 6×132 bolt pattern, and 74.5mm centerbore.

The Bridgestone Alenza A/S 02 carries a TPC Spec label. TPC Spec (Tire Performance Criteria Specification) means a tire meets the specific handling, safety, and ride comfort standards that General Motors requires for their vehicles. You do not need to buy a TPC Spec tire when replacing your OEM tires. Any tire meeting the size, load index, and speed rating requirements is a valid replacement. The ENLITEN designation is Bridgestone’s EV-optimized technology, combining a silica-rich compound, optimized tread pattern, and construction tuning aimed at reducing rolling resistance and extending range.

Before You Buy

Tire size. The OEM size is 255/60R19. Two common alternatives fit the 8.5-inch rim well: 265/60R19, which is roughly 1.5% larger in overall diameter, and 265/55R19, which has a slightly lower profile and is roughly 1.8% smaller in overall diameter. Both stay within the safe ±3% diameter threshold. For all compatible sizes, see the 255/60R19 tire table.

Load index. The OEM tire carries a 109 load index at standard load (SL). Match or exceed 109 on all four corners when replacing.

TPMS. The Blazer EV uses direct TPMS with 433 MHz sensors. Sensors stay in the wheel during a standard tire swap and do not need to be replaced. After mounting, the Auto Learn system will recognize the new sensor positions automatically after approximately 10 minutes at above 15 mph. If the system does not pair automatically, a manual relearn can be initiated through the infotainment screen settings using a standard GM TPMS activation tool.

Spare / Tire Mobility Kit. The Blazer EV does not include an OEM spare tire. Chevrolet provides a Tire Mobility Kit consisting of an air compressor and tire sealant canister. The kit handles small tread punctures only and will not seal a sidewall blowout. Consider roadside assistance coverage for long-distance driving.

AWD tread depth tolerance. GM specifies tread depth across all four wheels must stay within 2/32” to 3/32” of each other. If replacing fewer than four tires, place the tires with the most remaining tread depth on the rear axle for optimal stability.

Grand Touring All-Season

The Bridgestone Alenza A/S 02 is a Crossover/SUV Touring All-Season. It is quiet, comfortable, and rated for rain and light snow without requiring seasonal swaps. It does not, however, carry a 3-Peak Mountain Snowflake (3PMSF) rating, whereas most Grand Touring All-Season tires do. The majority of Grand Touring All-Season tires do carry a 3PMSF designation and are the better replacement choice for owners who see real winter weather or want a more capable all-season than the OEM spec.

The Michelin CrossClimate2 and Continental SecureContact AW are both worth considering if you see significant winter weather. They carry the 3-Peak Mountain Snowflake (3PMSF) rating that the Alenza A/S does not.

Ultra High Performance All-Season

If you want sharper handling without giving up year-round usability, ultra high performance all-season tires improve cornering response and wet grip meaningfully over Touring All-Seasons at the expense of winter performance. The Blazer EV’s instant torque responds well to a firmer, more performance-oriented compound.

The Blazer EV’s larger tire size means Summer Performance tires in 19” sizes are very limited. See 255/60R19 for a wider variety of alternative tires.

Winter Tires

Cold weather cuts EV range and limits the grip of all-season tires simultaneously. A dedicated winter set handles both problems. If you regularly drive in snow or ice, a seasonal swap is the right call. For a narrower winter fitment, 245/60R19 reduces contact pressure on snow and ice and improves bite while staying within 2% of OEM diameter. Sizing is limited in the OEM 255/60R19, but Tire Rack offers pre-packaged Blazer EV winter wheel-and-tire sets in a more practical 18” diameter.

Performance Winter and Snow

Performance winter tires carry a 3PMSF rating and are fully winter-capable, but prioritize dry and wet handling alongside snow traction. The right choice for owners who cover highway miles through winter and want confident grip without sacrificing all handling dynamics.

Studless Ice and Snow

Studless ice and snow tires maximize winter traction on ice, packed snow, and in severe cold. Dry-road handling is softer than a performance winter, but in genuinely harsh conditions these tires make a measurable safety difference.

Mounting and Installation

If you do not already have a relationship with a local tire shop, Tire Rack ships tires to their highly-rated network of local installers who will mount, balance, and install. Order online and drive to your nearest installer.

• TPMS sensors stay in the wheel. Do not pay for new sensors on a routine replacement. A valve stem seal inspection is normal and worth doing.
• TPMS relearn. After mounting, drive above 15 mph for approximately 10 minutes. The Auto Learn system will automatically register the sensors. If it does not complete automatically, use the infotainment screen settings to initiate a manual match with a GM TPMS activation tool.
• Lug torque: 140 lb-ft (190 Nm). M14×1.5 lug thread. Confirm your installer uses a calibrated torque wrench.
• Tire Mobility Kit. There is no spare tire. Keep the OEM air compressor and sealant canister in the vehicle.
• AWD tread depth tolerance. Keep all four tires within 2/32”–3/32” of each other. Place tires with the most remaining tread on the rear axle.
• New tires go on the rear. When replacing in pairs on FWD variants, always install the newer tires on the rear axle.
