I need to replace at least 2 tyres on my Audi Allroad, I have used the Goodyear F1 and are currently using the Pirelli Allroad tyres which I prefer. Is it best to stick with either the Pirelli or Goodyear as they are designed for the Allroad ( so the tyres say ), or is it worth trying a different make like Michelin Primacy Etc Etc. I was told to stick with the above two makes as they have stiffer side walls designed specifically for the Allroads. They all have a rating of W which is way past the top speed of the car. Has anyone tried other makes of tyres on there Allroads excluding the above two. Any help appreciated. A.
