Overview & Specifications
The Radar Dimax R8 Plus 275/45R20 110Y is a performance-oriented tire specifically designed for SUV-type vehicles. This particular size features a 275 mm tread width, a 45% aspect ratio (sidewall height to width), and is built for 20-inch wheels.
It carries a robust load index of 110, meaning each tire can support up to 1060 kg (2337 lbs), and boasts a “Y” speed rating, suitable for speeds up to 300 km/h (186 mph). Positioned as an entry-level, budget-friendly option, the Dimax R8 Plus falls into the C1 class, offering a compelling value proposition.
Performance Characteristics
For drivers with a sporty style, the Radar Dimax R8 Plus is engineered to provide responsive handling, effectively transferring engine power to the road. This translates into a more confident feel during acceleration, braking, and cornering, contributing to an overall comfortable driving experience within its class.
In terms of EU label values, the tire is rated ‘E’ for fuel efficiency and achieves a ‘B’ rating for wet grip, indicating decent performance in rainy conditions. Its rolling noise is also rated ‘B’, producing 73 dB. This noise level is moderate – it’s neither exceptionally quiet nor overly disruptive, striking a balance for everyday driving.
Additional Features
It’s important to note that the Radar Dimax R8 Plus 275/45R20 110Y does not include a dedicated rim protection feature. A rim guard is a reinforced area on the tire designed to shield your wheel rims from potential curb scratches or impacts.
Furthermore, this tire is not designated as a “reinforced” (XL) tire, meaning it does not offer a higher load capacity than standard tires of the same size. Always consult your vehicle’s owner’s manual or door jamb sticker to determine if your vehicle requires reinforced tires.
Finally, this tire does not incorporate run-flat technology, so a spare tire or roadside assistance plan is recommended.
