Match the size printed on your current sidewall to 205/75 R15, then confirm against the door jamb placard or handbook. If your vehicle lists more than one approved size, stick to one of those options and keep the same size across each axle.

Use the vehicle placard to select a load index and speed rating that meets or exceeds the manufacturer requirement. This size is commonly used on vans and pick-ups, so higher load ratings are often specified, and some vehicles require a commercial speed symbol such as R. Never choose a lower rating than specified, especially if you carry tools, passengers, or tow.

Choose C-rated (commercial) if your vehicle placard specifies C tyres or if your current tyres show a C marking on the sidewall, as they are built for higher loads and pressures. Reinforced (often marked XL) may suit some SUVs and pick-ups where extra load capacity is needed without a full commercial construction. If your vehicle was designed for standard passenger tyres, avoid switching to C-rated unless the manufacturer specifies it.

Only if the vehicle manufacturer approves it. Moving from 205/70 R15 to 205/75 R15 increases overall diameter by about 20 mm (around 3%), which can affect speedometer accuracy and may cause clearance issues under load or on full steering lock. Check approved sizes in the handbook and, if in doubt, ask a fitter to confirm compatibility before ordering.

Yes, all-season options are available in 205/75 R15 and can be a strong choice for UK drivers who want dependable wet grip and more confidence in colder months. Look for the 3PMSF symbol if you want winter-capable performance, and match the correct load and speed ratings for your vehicle. If you regularly drive in heavy snow or on untreated rural roads, consider a dedicated winter pattern instead.
