Understanding tyre size, load index, speed rating, seasonal options and the EU tyre label — what actually matters when choosing new tyres.
Choosing tyres doesn't have to mean guessing between whatever's cheapest and whatever sounds most impressive. A handful of details on the tyre itself, and a clear sense of how you actually drive, cover most of what matters.
A marking like 205/55 R16 91V isn't random: 205 is the tyre's width in millimetres, 55 is the sidewall height as a percentage of that width, R16 means radial construction on a 16-inch rim, and 91V is the load index and speed rating together. Matching these to your vehicle's specification — found in the handbook or on the door-jamb sticker — is the starting point, and it's not somewhere to guess or downgrade to save money.
Beyond the size itself, it's worth thinking honestly about your driving: mostly short local trips, regular motorway miles, a heavier vehicle that's often loaded, or a car that sees genuinely poor weather. None of these mean you need the most expensive option available — they just narrow down which characteristics actually matter for your situation.
Summer tyres are the default for most of the year and perform well in dry and wet conditions. Winter tyres use a softer compound that stays flexible in the cold, improving grip on icy or snowy roads, but they wear faster and grip less well once temperatures rise. All-season tyres are a compromise between the two, suited to drivers who'd rather not swap tyres twice a year but don't face extreme conditions either way.
Every tyre sold in the UK carries a label rating fuel efficiency, wet-weather grip and external noise. It's worth checking alongside the price rather than instead of it — two tyres at a similar cost can have meaningfully different wet-grip ratings, and that's the rating most directly tied to stopping distance in the rain.
The UK legal minimum is 1.6mm of tread across the central three-quarters of the tyre, all the way round. Meeting that minimum doesn't automatically mean a tyre is otherwise safe — condition, damage, pressure and your vehicle and tyre manufacturer's own guidance all matter too, and wet-weather grip can decline before a tyre reaches the legal limit. For more on what affects how long a tyre lasts in the first place, see our guide on tyre lifespan.
Budget genuinely varies by household, and a brand name or price bracket on its own doesn't tell you how a specific tyre will perform. Whatever you're considering, checking the label ratings above still applies.
Once you've settled on a size and type, correct fitting — balancing, torque and a check of the valve — matters as much as the tyre itself.
