Hello and greetings from the BMW Forum I hope one can help here, it’s about a C70 D5 that was tuned by HEICO. Besides engine tuning and exhaust system the chassis was also changed, as well as Heico 19″ rims with 235 tires installed. On the rear axle there are also track widenings. It is about that all four tires drive off more strongly on the inside and after approx. 18,000km a new set is necessary. It was very often repaired/checked by Volvo and after initial replacement of track rods on the rear axle all measured values were found to be ok (up to the exchange had already two tire places at the HA occurred). Also a free workshop has now checked the track/sturz and confirmed that all values are in the specified areas. So far only the Pirelli P Zero tires with which the Heico rims are sold have been used. maybe there is also Heico – drivers who have experience here. PS: today (again) new tires were installed, but this time Hankook V12 evo
