The Lucid Air leaves the factory on 245/35 R21 and 245/40 R20 and 245/45 R19 depending on wheel size, and the 245/45 R19 102Y XL below is the one most owners are replacing. XL is not optional here; it is what the car was type approved on. It is staggered: a 245 section at the front and a 265 at the back, so the two can never be swapped across axles and the rear goes first. The BMW i5 takes the same size.
| Generation | Trim | Wheel | Tire size | Load index | Speed | Construction | Marking | Pressure |
|---|---|---|---|---|---|---|---|---|
| Current | Pure, Touring, Grand Touring (19in) | 19in | 245/45 R19 | 102 | Y | XL | none | see plate |
| Current | Pure, Touring, Grand Touring (20in) | 20in | 245/40 R20 front, 265/40 R20 rear | 99 | Y | XL | none | see plate |
| Current | Touring, Grand Touring, Dream Edition (21in) | 21in | 245/35 R21 front, 265/35 R21 rear | 99 | Y | HL | none | see plate |
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.
The Air is square only on the 19 inch wheel. On 20 and 21 inch it is staggered, 245 front and 265 rear, so those sets cannot be rotated across axles.
The 21 inch pair are HL (high load): 245/35 R21 99Y front and 265/35 R21 103Y rear. Ordinary XL tires in those sizes stop below those indices, so the replacement must be HL-marked.
The placard pressure for the 19 inch rose from 42 psi on 2022 and 2023 cars to 49 psi from 2024. The 20 and 21 inch stay at 42 psi.
Every Air fitment is Y-rated, 300km/h, a requirement only the Lucid Gravity matches among the American electric models here.
How these were chosen. Everything here already clears this vehicle's own load index, speed rating and construction class. Each heading is a question about use rather than a ranking. The whole method.
Graded A for wet grip, and nothing else that fits is graded higher. Graded C for rolling resistance. EPREL registration 676712.
Graded A for rolling resistance, the best of anything here, and that is the figure that shows on the range display. Graded B for wet grip. EPREL registration 2584460.
Measured at 69 decibels, the quietest of the set. Graded A for wet grip, and nothing else that fits is graded higher. EPREL registration 2650388.
A winter tire, so a second set rather than a replacement for what is on the car now. Graded D for wet grip. Graded B for rolling resistance. EPREL registration 727667.
Rated below the speed this vehicle left the factory at, which is permitted for a winter tire and is why it carries a T or an R. The load index and the construction class still match. Do not exceed the tire's own rating while it is fitted.
Ordering is by the registered label figure, not by anything we think of them.
A high performance summer tire available in the Y rated sizes that heavy, fast electric cars are specified with.
An all-season tire for electric cars, which is a sensible default in a climate that rarely makes a full winter tire worth the second set of wheels.
A studless winter tire built for the weight and the rolling resistance demands of an electric car.
Rated below the speed this vehicle left the factory at, which is permitted for a winter tire and is why it carries a T or an R. The load index and the construction class still match. Do not exceed the tire's own rating while it is fitted.
A Korean-built summer tire that turns up as original equipment more often than its profile suggests, graded A for fuel efficiency.
A touring summer tire built with Bridgestone's Enliten construction, which cuts weight and rolling resistance across the range rather than in one model.
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.
