What is the English name for radial tyres in the UK car market?

Radial tyres (marked with 'R' on the sidewall) are the standard construction for most modern car tyres in the UK, including popular models like the Tesla Model 3 and Nissan Leaf. These tyres feature steel belt layers arranged at 90 degrees to the direction of travel for improved durability and performance. In the UK motor industry, they're commonly referred to simply as 'radial tyres' rather than using the Chinese translation '子午线轮胎'. This construction type offers better fuel efficiency and handling compared to older cross-ply tyres, making it the preferred choice for most UK vehicles from brands like BMW, Audi and VW.
