Mister Procrastinator here.....
Our PC was built in the spring of 2007. It is now spring of 2021, 14 years later. I am finally replacing the original tires with 38716 miles as stated on the odometer. The last cross-country trip we took was in August 2018 so our PC has been idle for nearly 2.5 years due to a focus on vacations in Europe with extra focus on Greece with Irene's family there, Egypt, and the Holy Land Israel. But we are are back focusing on the good old USA so it's time to "reset" our PC with new tires and all fresh fluids.
Our original tires are just now starting to show some minor cracking as shown here, seen around the tire size.
Here is the thread wear on the rear tires that is very nice and even. I never rotated them.
Here is one of two front tires, both worn poorly, caused by bad shock absorbers, those red Koni-RVs that were unevenly adjusted, also made worse when the top mounts worn away.
It is the perfect time to give our PC the full treatment with Alcoa wheels. The way it works is that you replace only the wheels that show. The inner duallies remain original steel. These cost me $1,500 HERE
. I still await for Alcoa-specific Borg valve stems HERE
(not extenders) than extend out for easy air filling.
I will be stopping by Discount Tire to purchase 6 new Michelin Agilis CrossClimate 115/112RE tires of the exact same size and load rating. I will mount them myself at my church where I volunteer as a mechanic for the under-resourced, to assure the wheels don't get marred, then return to Discount Tire to get them balanced with stick-on wheel weights placed on the hidden inside. They quoted me $1316 for tires, tax, and balance.
I will reassign the two front steel wheels to the inside rear and discard the two front tires. The original 4 rear wheels and tires will be sold locally. Hopefully someone who drives a lot locally with an E-series Box truck or landscape truck who lives on a tight budget will value them.
I will also be selling my PC-supplied wheel cover set. They would do nice for someone with a motor home that lacks them.
