Hi guys, I got rare problem with my tyres. I bought them with wrong load index. Instead of 245/40/18 97Y i took 245/40/18 93Y. That is huge difference in load, about 70 kg per tyre. Now the question is can i drive the car with those tyres? Car is A6 Avant 3.0 TDI I see in the manual max front axel load - 1300 kg and rear is 1280 kg. Please give me some advise.
