Yes. Entering your UK registration should return tyre sizes that match your Seat Altea, then you can choose between suitable brands, patterns and performance levels.
Along with the size (width, profile and rim diameter), match the load index and speed rating shown on the tyre sidewall, and keep an eye on any notes such as reinforced (XL) if your current tyres use it.
Summer tyres suit most UK conditions above about 7C and offer strong wet and dry performance. All-season tyres are a good year-round choice for mixed temperatures and frequent rain. Winter tyres are best if you regularly drive in cold regions or on untreated roads where ice and snow are more likely.
The UK legal minimum is 1.6 mm across the central three quarters of the tyre around the full circumference. Many drivers replace at around 3 mm for better wet braking, and earlier if you notice damage, uneven wear or persistent pressure loss.
After selecting tyres, you pick a nearby fitting centre, choose an available appointment slot and complete payment online. The tyres are delivered to the garage, and you attend at the booked time for fitting.
