smart #1 tyres
The smart #1 leaves the factory on 235/45 R19 and 235/50 R18 depending on wheel size, and the 235/50 R18 101V XL below is the one most owners are replacing. XL is not optional here; it is what the car was type approved on. The BYD Atto 3 takes the same size.

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.
What changes on this car
The #1 shares Geely's SEA platform with the Volvo EX30 and Zeekr X. Its two sizes keep the same 235 width, so the only choice is between an 18 inch 235/50 R18 101V and a 19 inch 235/45 R19 99V, both XL.
The Brabus is listed on exactly the same two sizes as the standard car, despite having 315 kW to the standard car's 200 kW. Of the two, the 18 inch is the stronger tyre at 825 kg; the 19 inch drops to 775 kg.
No tyres listed against this fitment yet. Product specifications are published from each manufacturer's own data and that work is not finished for 235/50 R18. Match or exceed every figure in the table above and you cannot go far wrong.

Common questions
- What size tyres does the smart #1 take?
- It runs 235/45 R19 and 235/50 R18. The exact fitment for your car is on On the driver's door jamb, on the B-pillar.
- Can I fit a cheaper tyre to a smart #1?
- Only at 235/50 R18 101V XL or better. That is the figure to hold: a tyre below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
