It depends on the Ibiza year and trim, so check the tyre sidewall (for example 195/55 R15) or use the registration search to confirm the correct size, load index and speed rating.
The legal minimum is 1.6mm across the central three-quarters of the tyre, around the entire circumference. Many drivers replace at about 3mm for better wet grip.
All-season tyres can be a good choice for year-round UK driving, especially if you want extra reassurance in colder, wetter months. Look for the 3PMSF marking if you want stronger snow performance.
After finding the right tyres via registration or size, you select a nearby fitting partner and an available appointment time at checkout, then take your Ibiza to the chosen garage for fitting.
