battle for mileage, 2007 Century, 14L EGR Series 60

I hit the fast idle and set it up to 1000 RPM to do that test.

 

don't forget the ear plugs.....

 

worse than a boat they are....

 

The latest in this saga is the set of 4 used virgin Bridgestone M710's with 10/32 tread left on them. I have a set of 8 michelin recaps that were on the truck. 3 of them had a really bad wear pattern in them. (hint, DON'T run your tires with 65 lbs of air) The precipitate to that was coming home I had a sidewall blow out on one of the drives. Just a rapid deflation, nothing came apart.

While dealing with the flat tire, they wanted $380-390 for a single tire. They wanted $875 for a matched set of used virgin tires. The recaps were so weather-checked and bothersome to me, I spent the money.

What I noticed already is that I am running about .25 mpg better fuel mileage. The noise and vibration going down the road is gone and this guy will likely never run recaps again if I can help it.

 

the wear pattern in the old tires was a result last January of running with 65 lbs of air in the tires. The set of recaps that were on the truck were there when I bought the truck in July last year.

Even at .25 mpg, that's a savings of $250 per month. About $3000 annually. That MORE Than pays the difference of $1200 between recaps and virgin Tier 1 tires.
