Hello forum members, hope all are well. Just some definitive advice needed regarding the best positions for tyres. Currently have 2x Continental Conti Sport Contact 5P RO1 7mm tread on front and 2x Dunlop SP Sport MAXX GT RO1 6mm tread on the rear. Tyre size is 275 30 21. Is this the best solution for the slightly newer Contis to be on the front? or the other way around? Does anyone know the ratio for the application of power? is it biased to the front or rear? Car is 2013 (63) A7 3.0 tdi quattro Black Edition. Many thanks.
