I replaced my firestons at 45000 with the exact same tire no complaints no regrets.

 

have 2007 lt2 just replaced oem tires 73000 miles still thread leaft weathered

 

I am in the midst of changing my tires over. I had the Firestone Firehawks and they have just over 50K on them, They still have some tread, but it was starting to Hydroplane in the rain and it was scary at times. They were never great in wet weather. I am putting Hankooks on. I don't drive it in the winter, so I went with a summer tire.
