Hello! I had a great experience in November with my Antara 2.0 Cosmo. With external chip! (177 HP) First: Great car, even if the consumption is a little too high and the suspension is a little too lax. So: Just before the change on winter ice I found four totally worn tires. Then I immediately went to my Opel dealer. I explained to me that I was on the road with far too little air in the tires! And that after about 12,000 km!!! Only 2.3 bar are far too little!!! But exactly this value is prescribed by Opel on the inside of the driver’s door as a tyre pressure for 3 people without charge. ??? Besides, my Anatara was regularly in the workshop: inspection, re-adjusting the oil Nivueu sensor, replacing torn leather steering wheel, unfounded lighting up some control lamps, … And the Opel workshop people do not leave my car from the yard again with too low tire pressure?!!!? Or do they?! 😉 Auc h the negated meim Opel dealer, of course the car will be checked out! Now I have been waiting for three months for answer. Is apparently tested at the factory. What experiences do you have??? Are your tyres flat or down?
