Getting ready for a ride to the Appalachians in a month and found a weak rear Pirelli GT. They are lasting about 3500 miles for me; right at average for my 30 rear tires. (I get 3 rear : 4 front).
Trying to follow my own advice (Wheels Off Maintenance Checklist in FAQ) , I found my Brembo rear pads ready for a change (10,111 miles/ 16.300 km). Inboard more than outboard, which tells me the pistons need cleaned, equalized, pin polished and lubed, and fluid bled.
The brake side rear wheel bearing was also played up. Fourth one on that side. Only the third on the drive side, which felt okay, but my trusted friend, Josh, who found the bad bearing says, "Change them both." I believe in this guy!
The last bearings were made in China and lasted 1/2 as long as the OEM, Euro-made stuff. I'm trying to source better made bearings.
So . . . when that tire needs changed, folks: Wheels Off Maintenance Checklist!
