Dunlop has introduced the new SP 344*, renewing its SP 344 regional haul steer tyre range in 17.5” rim sizes.
The latest generation of the series is designed for demanding delivery and regional haul service requirements. Dunlop says the new iteration features increased robustness combined with good mileage, even wear, excellent handling and wet braking performance.
The SP 344* features a new tread compound, which provides increased robustness and better wet grip compared to its predecessor. Combined with the robust carcass construction, the new Dunlop SP 344* increases fleet efficiency in regional haul service conditions.
“The new Dunlop SP 344* in 17.5” is aimed at fleets engaged in distribution and regional operations,” said Marc Preedy, Goodyear Dunlop UK commercial director. “For this type of operation good mileage, even wear and robustness are vital for efficiency. So we focused on these performance criteria when we developed the new SP 344* to make sure the tyre delivers especially in these areas. We are convinced that the new Dunlop SP 344* with its improved performance will continue the successful history of the SP 344 series.”
Dunlop says the new tyre’s compound improves robustness, a key feature in delivery and regional haul service applications, and wet grip performance. In addition it improves resistance of groove cracks. The blade and groove density of the tread pattern provides wet skid resistance. The five rib design and closed shoulder ribs help, in combination with the new tread compound, to increase mileage, improve handling and make wear more even. Another tread feature is the special groove shape, which has stone rejection capabilities.
The new Dunlop SP 344* steer tyres were available from December 2014 in sizes 245/70R17.5 136/134M TL and 265/70R17.5 139/136M TL. In terms of EU tyre label ratings, both tyres are rated B for wet grip with D for fuel efficiency. External noise grades are 71dB (two waves) for the 245/70R17.5 and the 265/70R17.5 139/136M is labelled 73dB (two waves).
