That's not good news on the tires. I live in the upper peninsula of Michigan....long winters and lots of snow.
I ran snow tires year around in my last 80 series because it was mostly parked in the warm months. I was hoping to avoid replacing these Coopers because there is 80% tread on them.
Beyond that, I've been doing to small things to the 100. Raised the spare tire up, lost the running boards, mounted my ham radio gear, manual switch for DRL's, pulled the back seats, yanked out all the old cell phone he crap and wiring the previous owner had.
New bilsteins should arrive today. The rear no brand shocks are done. Was dancing sideways on some mild washboard a couple days ago.
Need to track down a rotational squeak from the brakes. It's driving me mad. Thought was the pad wear indicator from the rear but they have lots life left. Maybe slightly warped rotor?
