Read the retailer’s description

Supplied by mytyres.co.uk. These are the retailer’s product claims, not independent test findings from Tyres Compared.

New generation of tread compound perfectly matched up with nanomaterials can upgrade wet grip and handling performance. Sound pressure distribution for AS-3 EV was simulated and calculated with acoustics software to suppress annoying noise and enhance driving comfort. Diversion design in circumferential grooves can drive up water in circumferential grooves promptly and effectively, and also help to reduce the noise caused by airflow friction with groove wall. Bevel design on lateral grooves of tread shoulder can reduce noise and increase block stiffness for prevent tread pattern deformation in later tire life. .

Source & product identity

Offers are matched by validated EAN/GTIN with matching brand, size, load and speed; manufacturer part numbers must also agree when both records supply them. Tyres without a valid GTIN remain retailer-specific. Merchant specification: 275/45 ZR21 110Y XL, with rim protection (MFS), [EV+].
