Mobile Truck Tyre Service in Rosenheim — 24/7 Roadside Breakdown Assistance

Coming down the A8 from the Kiefersfelden border crossing, a Volvo FH 500 hauling a refrigerated Schmitz unit received a TPMS alert on the right rear outer drive tyre just before the Rosenheim-Ost exit. Alpine descents put heavy thermal load on tyres, and the driver did not want to risk the last stretch into Rosenheim with a suspect reading. He pulled into the Rosenheim services and called LKWHelp24. The technician arrived and found the outer dual on the rear drive axle at 6.2 bar instead of the rated 9 bar. A nail was embedded halfway through the shoulder block, not fully penetrated but working loose under the heat cycles from the mountain descent. It had not yet caused a full leak but pressure was falling steadily. The nail was removed and the penetration depth and angle assessed. It was too close to the shoulder-to-sidewall transition for a safe vulcanised repair. The outer dual was swapped for a new Michelin X MultiWay HD from the service van. Both drive duals were then pressure-matched to 9 bar and the TPMS sensors re-synced before the wheel was torqued back on. The Volvo left Rosenheim services inside fifty minutes of the first call, continuing on the A8 toward Munich with the refrigerated cargo still within temperature limits. Traunstein dispatch was updated and the delivery rescheduled without penalty. No crane or recovery vehicle was involved at any point.
