Im finding my D697's are wearing quicker than I would have expected too. I rotate my 6 tyres so I estimate that each tyre has done around 26,000 (considering I've travelled nearly 40,000km since purchase and each tyre is on for roughly 2/3s of that time)
I've been running bridgestone A/T's for quite a while now and this lot seems to be the quickest wearing I've come across. Might be time to change brands for the next set.
