Treated the X5 to a new set of Yokohama YK580 tires after the last set managed to last 43,000 miles.

Then tried not to be too upset when the wiring harness on the fan shroud fell into the engine fan, shorted out, and fried the auxiliary fan and disabled my air conditioning on a fine 103 degree day in Texas.
At 258,984 miles, things will happen.
At least these tires will last longer thanks to my new rear suspension bushings and proper alignment!
