If wet braking matters most
Graded A for wet grip, and nothing else that fits is graded higher. Graded C for rolling resistance. EPREL registration 676712.

The Volvo EX30 leaves the factory on 225/55 R18 and 245/40 R20 and 245/45 R19 depending on wheel size, and the 225/55 R18 102V XL below is the one most owners are replacing. XL is not optional here; it is what the car was type approved on. The BMW iX1 takes the same size.
| Generation | Trim | Wheel | Tyre size | Load index | Speed | Construction | Marking | Pressure |
|---|---|---|---|---|---|---|---|---|
| Current | Single Motor and Twin Motor (18in, UK) | 18in | 225/55 R18 | 102 | V | XL | none | see plate |
| Current | Plus and Ultra (19in) | 19in | 245/45 R19 | 102 | V | XL | none | see plate |
| Current | Single Motor and Twin Motor (20in, UK) | 20in | 245/40 R20 | 99 | V | XL | 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 tyre.
Every EX30 fitment is square and XL, so a set of four is one size on each wheel option.
The 18 and 19 inch tyres share a load index of 102, 850 kg, even though the 19 inch is 20 mm wider. The 20 inch drops to 99, 775 kg, on a sidewall of about 98 mm.
The EX30 sits on Geely's SEA platform rather than a Volvo architecture, and none of its sizes is shared with the larger EX40.
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 tyre, 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 tyre and is why it carries a T or an R. The load index and the construction class still match. Do not exceed the tyre'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 tyre available in the Y rated sizes that heavy, fast electric cars are specified with.
An all-season tyre for electric cars, which is a sensible default in a climate that rarely makes a full winter tyre worth the second set of wheels.
A studless winter tyre 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 tyre and is why it carries a T or an R. The load index and the construction class still match. Do not exceed the tyre's own rating while it is fitted.
A Korean-built summer tyre that turns up as original equipment more often than its profile suggests, graded A for fuel efficiency.
A touring summer tyre built with Bridgestone's Enliten construction, which cuts weight and rolling resistance across the range rather than in one model.
Continental's efficiency summer tyre in the sizes heavy electric cars actually use, available in some fitments with the ContiSilent foam liner.
Designed for electric cars from the ground up rather than adapted from a combustion tyre, and the winner of the 2025 Auto Bild EV tyre test.
An efficiency-first summer tyre aimed squarely at range rather than at cornering.
Every figure here comes from one tyre 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.
