I use Avons on my MX5 but that only does around 1k a year so the wear rate is far less of a concern than anything else!This. some brands are only good for 10,000 miles, some Ive done 60,000 miles in.
I put some Avons on my Touareg since it was due to go back on 15th Nov and with only 6 months left didn't want to put michelins on it. Car isnt going back for another 6 months now due to delays in the new one and I had a look at my tyres the other day and no was will they last another 6 months. Ive only done almost 9k on them and only a mm left to the indicators. WIll be having to put another set on by xmas at the latest I reckon.
avons are very soft and wear quickly although they are great "budget" tyres for wet grip.
Those bridgestones are decent and most users seem to get around 25,000 miles from them.
I've had Bridgestones on a couple of my cars (Potenza's) and one of the wifes (Turanza). Never managed to wear a set out before they cracked up to the point I wasn't happy running them
