The Kia EV6 GT is the high-performance variant of the EV6, producing 576 hp from dual electric motors. It is the most powerful production Kia ever made. The GT uses a square (non-staggered) 255/40R21 setup on all four corners, on 21-inch wheels — wider and lower profile than the standard EV6's 235/55R19 and 255/45R20 fitments. GT owners cannot use standard EV6 tire recommendations without verifying fitment.
Kia EV6 GT Tire Sizes — How They Differ from Standard EV6
Standard Kia EV6 (RWD and AWD): 235/55R19, or 255/45R20 on the GT-Line AWD — symmetric, rotation possible.
Kia EV6 GT: square 255/40R21 on all four corners, on 21-inch forged wheels. Because front and rear match, normal rotation is possible — unlike most staggered performance EVs.
The GT's 255/40R21 tire is wider than the standard EV6's tire, designed to handle the 576-hp peak torque delivery from the dual-motor AWD system. All four corners see meaningful stress under hard launches.
The 21-inch diameter with a 40-series aspect is a demanding high-performance fitment. Verify replacement availability in 255/40R21 before choosing a brand.

Frequently asked
What size tires does the Kia EV6 GT use?
255/40R21 on all four corners (square, not staggered). This is different from the standard EV6's 235/55R19 or 255/45R20; do not use standard EV6 tire recommendations for the GT.
Can you rotate Kia EV6 GT tires?
Yes. The square 255/40R21 setup on all four corners can be rotated normally, unlike most staggered performance EVs. Regular rotation helps offset the faster wear from the GT's 576-hp output.
What are the best tires for the Kia EV6 GT?
Michelin Pilot Sport 4S in 255/40R21: the top choice. Continental SportContact 7 as an alternative. Pirelli P Zero for performance summer compound.
How do I know when my EV6 GT needs new tires?
With all that power going through all four corners, the tread goes faster than on a normal EV, so check it often with a penny. Look across the whole width of each tire, since hard launches round the shoulders early. A drop in wet grip or range is another cue. A shop can read all four and tell you what's left.
Where can I get EV6 GT tires installed near me in West Georgia?
We'll match you with a local shop in the Carrollton and West Georgia area that can order the GT's larger performance size and mount and balance it without risking the forged wheels. Because the GT runs the same size on all four corners, regular rotation is possible and worth doing to stretch the tread. Getting matched is free.
