Has anyone replaced their tire/s on the ctx1300 yet? I have about 1400 miles on the oem Bridgestones and it looks to me like the rear has about that left in it. I measured the tread depth when new at .220" on the rear and .150" on the front. Rear tire has .130" at the lowest point (wear bars). I am concerned about this because the wife and I are riding to Arizona from Arkansas at the end of August. I don't want to replace the tires mid trip. Any advice as to replacement tires would be appreciated. Btw, I am 70 years old and ride the bike very conservatively. Tire pressures checked daily and are set to factory recommended pressures. 36 psi front and 42 psi rear. Thanks in advance.
