Check the tyre size printed on your current sidewall and compare it with the driver door jamb sticker or your handbook. Some cars use this size only on one axle, so also confirm whether it is specified for the front, rear, or both.
Yes, many Smart Fortwo models use 145/65 R15 on the front with a wider tyre on the rear. Keep the manufacturer’s staggered set-up, and do not swap sizes front to rear unless your handbook explicitly allows it.
Match the load index and speed symbol shown on your current tyres or listed on the vehicle placard, then choose the same or higher rating. For example, if your tyre is marked 72T, select 145/65 R15 with 72T or higher to maintain the correct carrying capacity and speed capability.
They can be a strong choice for compact cars that see frequent wet roads and occasional cold snaps, especially if you want one tyre for year-round use. Look for the 3PMSF marking if you want extra reassurance in winter conditions, and compare wet grip ratings if motorway rain performance matters to you.
Replacing tyres in pairs on the same axle is usually best for balanced grip and predictable braking, particularly on light, short-wheelbase cars. If your car uses a wider rear size, replace the two tyres on that axle together and keep tread depths close to avoid uneven handling in the wet.
