I do aroun 140 miles a day on my SH.. back and forth to work... all freeway at 80-90mph in 110 degree weather in the summer months...

I have just over 7500 miles on the rear 208 and I like what I see...

 

If your commute is east from Riverside, then I just don't get it. That direction would put you in a similar temperature zone to me and I can only DREAM [/B] (cue classic monty python skit) of that kind of mileage.

Me: track tires= 2k miles
sport tires=2.5-3.5k miles
sport/touring=4.5k miles

These are burned up in the middle due to the long distances @ 80-85mph I ride to get to the twisties and lot's of short but hard runs through the gears around the home area

 

I got 4000 miles on the 208s when the theads showed, but I ride it pretty hard and I LOVE corners. Put about 7 days of hard riding at deals gap. Just replaced it with a BT 014 and I like the bridgestones a little better.

 

I run the I215 south to the I15 South from Sun City to San Diego... every day.... and I just took that pic tonight when I got home.... just over 7500 miles since 27 June 05...

 

Amazzzing!! I never get anywhere near that and it looks like you've got plenty left.

 

I was expecting a LARGE flat spot down the middle before now... and its barely noticeable in the pic..... about 2-2.5" wide, but you cant feel it yet...
