R21 TYRES NZ: 21-INCH TYRES FOR PREMIUM SUVS
R21 is the premium choice — factory fitment on luxury SUVs like Audi Q7, BMW X5, Range Rover, and Porsche Cayenne. We stock 265/45R21 with free North Island delivery, and can source other R21 sizes on request.
🔧 WHAT ARE R21 TYRES?
R21 tyres fit 21-inch diameter rims — the choice for premium and luxury SUVs. This size has become increasingly common as manufacturers push towards larger wheels for improved aesthetics and handling on high-end vehicles.
WHY R21?
- Premium Aesthetics — Larger wheels fill wheel arches better and give vehicles a more commanding presence
- Handling — Shorter sidewalls (typically 35-50 series) provide sharper steering response
- Factory Fitment — Standard on many luxury SUVs from 2018+ model years
- High Load Ratings — Designed to handle the weight of large SUVs (2,000kg+ vehicles)

❓ R21 TYRE FAQS
R21 indicates the tyre fits a 21-inch diameter rim. The "R" stands for radial construction. For example, 265/45R21 means 265mm width, 45% aspect ratio, radial construction, for a 21-inch wheel.
R21 is primarily used on premium and luxury SUVs including Audi Q7/Q8, BMW X5/X6/X7, Range Rover/Range Rover Sport, Porsche Cayenne, Mercedes GLE/GLS, Tesla Model X, and super SUVs like Lamborghini Urus. It's also found on some high-performance sedans and sports cars.
R21 tyres are premium products requiring more materials, higher performance specifications (typically Y-rated for 300km/h), and lower production volumes. They're designed for heavy luxury SUVs requiring high load ratings. However, our Anchee 265/45R21 offers excellent value compared to OEM brands like Pirelli or Continental.
Yes, 265/45R21 is one of the most common R21 sizes, fitting many premium SUVs as factory fitment. It's used on Audi Q7, BMW X5/X6, Range Rover Sport, Porsche Cayenne, Mercedes GLE, and Tesla Model X among others. It's often specified for both front and rear positions.
Currently we stock 265/45R21. For other R21 sizes like 275/45R21, 295/35R21, or 325/30R21, contact us for a quote — we can often source specific sizes on request with competitive pricing. Lead time is typically 2-4 weeks.
Many luxury SUVs come with run-flat tyres as standard. While our current 265/45R21 is a standard (non-run-flat) tyre, most vehicles can switch between run-flat and standard tyres. If you specifically need run-flats, contact us to discuss options.
