Check the tyre placard (door shut or fuel flap), your handbook, or the markings on your current tyres. The size must match what your vehicle is approved to use, and the load index and speed rating must meet or exceed the manufacturer specification. If you are unsure, choose the same size and rating as the tyres already fitted and confirm with your fitter before ordering.
The 80 profile is noticeably taller, which increases the overall rolling diameter by around 6%. That can affect speedometer reading, gearing, and wheel arch clearance, especially on full lock or over bumps. Only switch if your vehicle manufacturer lists 155/80 R13 as an approved alternative size.
Use the exact load index and speed rating shown on your vehicle placard or handbook, then match it when you buy. You can go higher, but never lower, as it can compromise safety and legality. If you regularly carry passengers or loads, prioritise the correct load index first, then pick a speed rating that meets the requirement.
Yes, although the choice can be more limited than in larger, newer sizes. All-season options can suit typical UK weather if you want one set year-round, with dependable wet grip and added cold-weather capability. If you drive in frequent snow or rural winter conditions, a dedicated winter pattern in 155/80 R13 may be the better match.
Most modern 155/80 R13 tyres are tubeless and are designed to seal directly to a compatible rim with a standard valve. Inner tubes are usually only needed for certain older wheel types or if a rim cannot reliably hold air. If your car is a classic or you are unsure about the wheel type, ask the fitting centre to confirm before fitting.
