The GMC Sierra EV is the premium electric truck sibling to the Chevy Silverado EV, sharing the Ultium platform but positioned above the Silverado in luxury and feature content. The Sierra EV Denali Edition 1 launched as a flagship EV pickup with unique fitments compared to the Silverado EV. It competes with the Ford F-150 Lightning Platinum and Rivian R1T Adventure.
GMC Sierra EV Tire Sizes
GMC Sierra EV Denali Edition 1 (launch trim): 275/50R24 on 24-inch Denali alloy wheels, a large, flagship-appropriate fitment.
Additional Sierra EV trims beyond Denali bring their own wheel and tire packages — sizes vary by configuration, so always verify against your door-jamb sticker rather than assuming a single fitment.
The 24-inch Denali fitment is a large-diameter truck tire requiring adequate load ratings for the Sierra EV's GVWR — other trims may use different wheel packages, so verify on the door-jamb sticker.
As a GM Ultium platform truck, the Sierra EV shares engineering with the Silverado EV — trucks in this family weigh roughly 8,500 lb at the curb before any payload. High load-index tires are required at maximum payload.
Best Tires for the GMC Sierra EV
Replacement options in 275/50R24 are limited — it is a new, flagship-EV size, so expect to special-order through a dealer or major online retailer rather than finding it on a shop's rack.
A highway touring tire matching the OE load rating is the right profile for Sierra EV owners who primarily drive on-road — quieter and more efficient than all-terrain rubber.
For genuine all-terrain traction, confirm a given tire line is actually produced in the factory 24-inch size before purchase — most A/T lines stop well short of 24-inch wheels.
The simplest path is matching the OE fitment exactly — same size, load index, and speed rating as the door-jamb sticker — which preserves range, ride quality, and load safety.
Frequently asked
What size tires does the GMC Sierra EV use?
275/50R24 on the Denali Edition 1. Other trims may use different wheel packages — verify with your door jamb sticker.
Are GMC Sierra EV tires the same as Chevy Silverado EV tires?
The Silverado EV RST uses the same 275/50R24 fitment as the Sierra EV Denali Edition 1 — both are Ultium platform flagship trims with similar weight requirements and large-wheel packages.
What are the best tires for the GMC Sierra EV?
Match the OE 275/50R24 fitment and load rating. Options in this size are limited, so plan on ordering ahead — your installer can source what is currently produced in the 24-inch fitment.
How do I know when my Sierra EV needs new tires?
Watch for tread worn toward the wear bars, sidewall cracks or bulges, tires past about six years, or a drop in range and grip. An electric truck this heavy can wear tires faster than a gas pickup, especially under load or hard acceleration. A shop can measure tread and check the sidewalls, and given the large fitment it is smart to plan replacements before you are down to the wire.
Why are Sierra EV tires so hard to find?
This large-diameter fitment is new and flagship-specific, so it is not something most shops keep on the rack yet. That usually means special-ordering through a dealer or major online retailer rather than same-day service. Plan ahead and give your installer lead time. A local shop can tell you what is currently produced in the size and get it in for you.
