Product description & features

The Dunlop SP SportMaxx RT is a summer performance tyre developed for sporty hatchbacks, executive saloons and performance coupés that need confident road grip and precise steering in warmer conditions. It’s tuned for fast A-road driving and motorway mileage, giving a planted feel when pressing on without losing everyday usability.

A stiffened tread layout helps keep the contact patch stable under braking and cornering, supporting accurate turn-in and consistent feedback through the wheel. Broad outer shoulder blocks improve lateral grip when loading the tyre in bends, while a more continuous centre area helps it track cleanly at speed. Wide circumferential grooves and carefully placed tread channels move surface water away efficiently, helping the tyre maintain traction and shorten stopping distances on wet UK roads.

For daily driving, these tyres are designed to wear evenly by distributing pressure across the tread, which can help maintain performance over time. Road noise is kept in check by a tread pattern that breaks up harmonic “hum”, and the compound aims to balance strong grip with sensible rolling resistance rather than focusing on outright softness. Selected fitments are also available in run-flat versions for vehicles that require them, and sizes typically span 16–21 inch rims.

You can buy Dunlop SP SportMaxx RT tyres online in all available sizes on Tyres.co.uk, with the choice of fitting at a nearby garage of your choice or having the tyres delivered to you.
