Hi all, A couple of questions concerning tyres: 1. I see that typically, regardless of wear, the general guidance is to change tyres after 5-6 years due to tyre aging. What are your views on this? 2. Do you trust the average tyre replacement centre to correctly jack up your 7 to replace the tyres or do you remove the wheels and bring them to the tyre centre? My 160S has plenty of tread on the tyres, but although the car is 5.5 years old now the DOT code suggests the tyres were manufactured between late 2015 and late 2016 and I'm wondering if I should change them, especially whilst I can probably still get Avon ZT7's. Cheers, Mark
