Find Tyres for 2021-present Lexus NX (AY20)
UK-market tyre sizes for the 2021-present Lexus NX, with chassis-code matching and trim notes.
About this generation
The Lexus NX is an SUV/crossover, so the original tyres carry a higher load index for the extra weight and ride height. Replacement tyres should match or exceed the original load rating.
This generation of the NX runs on 19-inch or larger wheels in some trims, which means short-sidewall tyres that handle precisely but are less forgiving on rough UK roads.
Chassis code: AY20. Use the chassis code to confirm you have the right generation when ordering tyres.

Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What do star/OEM markings mean on Lexus NX tyres?
Lexus approves specific tyres for many of its models, marked with a star (BMW), MO (Mercedes), AO (Audi), J (Jaguar) or similar. OEM-marked tyres are tuned for that car's suspension and don't always come from the major brand-name fitter as a stock item — they may need to be ordered.
What should Lexus NX drivers know about UK potholes?
UK road conditions are tough on tyres. Check sidewall bulges, cuts and tread depth regularly — especially on the inside edge, which often wears unevenly. A 20p coin gives a quick legal-tread check.
Are premium-brand tyres worth it on a Lexus NX?
On a Lexus NX, premium tyre brands (Michelin, Continental, Bridgestone, Pirelli, Goodyear) typically deliver longer tread life, better wet grip and quieter rolling. The cost difference is usually recouped over the tyre's life.
Do I need SUV-rated tyres on the 2021-present Lexus NX?
SUV-rated tyres carry a higher load index for the extra weight and ride height. Match or exceed the original load index. If you do mild off-road, all-terrain (A/T) tyres trade some on-road grip for better unpaved performance.
What's different about the 2021-present NX compared with other generations?
This is the 2021-present generation of the Lexus NX. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
