Hi. Looking for a bit of advice here please, the tyres on my Q5 on a 65 plate with 8t ( yes eight thousand) miles on the clock have been confirmed by local tyre fitters ( good reputable company) as perished. Front two outer side of tyre,Rear two bad cracks in the ridges of the tyres. Have checked the manufacturing date and they are showing week 27 of 2015. What action would you take and what outcome can I expect. Thanks.
