Check the tyre sidewall on your current wheels and compare it with the size listed in your vehicle handbook or on the door jamb sticker. If your vehicle runs different sizes front and rear, make sure you are buying 155/60 R20 for the correct axle position. When in doubt, match the full size and ratings exactly to avoid clearance issues on a 20-inch wheel setup.
Choose a 155/60 R20 tyre with a load index and speed rating that meets or exceeds the manufacturer specification for your vehicle. Do not downgrade either rating, as it can affect safety, handling and insurance validity. If you are fitting this size as part of an aftermarket wheel package, confirm the required ratings with your fitter based on the vehicle weight and intended use.
Only switch if your vehicle has approved alternatives and the wheel width and offset support the change. Moving away from 155/60 R20 can alter rolling diameter, steering feel and arch clearance, especially on tight-lock city cars and modified setups. Before buying, check for rubbing risk, ABS and speedometer implications, and whether the new size remains within legal and insurance requirements.
Yes, but availability can be more limited than common sizes because 155/60 R20 is a niche fitment. Summer tyres are usually the easiest to source, while all-season and winter patterns may come and go depending on brand and stock. If you drive year-round in mixed UK weather, consider an all-season 155/60 R20 option when it is available, or plan ahead for seasonal changes.
Replace tyres in axle pairs as a minimum so grip and braking remain balanced, particularly with a narrow size like 155/60 R20 where tread condition can noticeably affect stability. Replacing all four is best if wear is similar across the set or if you want consistent handling and road noise. After fitting, checking alignment can help protect the new tyres from uneven wear.
