Synergy DP209 11R22.5 146/143L HOVERVIEWThe Synergy DP209 is a commercial tire that's designed for use on the drive axle of semi-trucks and buses in urban applications. Closed shoulders fend off uneven wear for a longer tread life while also lowering road noises to improve ride comfort, and the DP209's optimized design reduces rolling resistance to enhance fuel efficiency. Wide grooves funnel water out of the tread to improve performance and traction in wet weather conditions, and the DP209's symmetrical tread pattern fends off uneven wear for a longer tread life.
