You guys seriously need to stop buying cheap tires that are on sale.

One tire talked about here is the bridgestone m726.

It's the absolutely 100% worst tire to buy. It totally kills your fuel mileage. It has 70% more rolling resistance then a good efficient tire.

Just punched it in to michelins fuel savings calculator, and get this, it costs you NINE THOUSAND DOLLARS PER YEAR over an efficient tire, like michelins XDA energy. That's a lot of gallons.

Double coin rlb400? $8400 per year.

Seriously, leave those cheap junk tires on the rack, and buy some good american tires, like MICHELIN.

At todays fuel prices, you can't afford not to.

 

Michelin is French :lol:

 

I used to only buy American made tires. Most of them won't stand behind them if something happens to them. I have had excellent service out of Double Coin. By the way, Double Coin is designed just like the Michelin. The only difference is the name on the tire and where it was manufactured. Navistar is putting Double Coin on their new trucks. So far I have had better service out of Double Coin than I have out of Goodyear or Kelly. The great part is that I pay much less for the tire. I have had Double Coin drives on my International for about 2 years now and they still have plenty of tread left. I don't have anything against Michelin other than the price. I can buy Michelin on national account, but can still buy Double Coin or other brands for less that do as well. I still get good fuel mileage with them.

 

I believe Michelin is actually the majority owner of Double Coin, so just take a wild guess where they get most of their engineering.

As for the rolling resistance calculator, can Michelin back these claims up with any independent testing results?

I'm sorry, but I am more than a little skeptical of their claims.

 

They actually, claim nothing! Some other brands, according to their calculator, has the same, or even lower rolling resistance, then Michelin.
So, it seems credible to me... :roll:

 

I'll stick with my big huge meaty open tread drives. They saved me once this past winter when I was able to make my way through 5 trucks stuck on a hill in Colorado at 2am during a blizzard.

I wouldn't be surprised if someone couldn't get a government grant to research fuel saving ideas for trucks. There are MANY simple experiments that would prove or disprove many claims.

I think many of these claims about rolling resistance are based on math and science without any real testing. In a perfect world with perfect conditions this may be true but that is not the case. I put these claims about rolling resistance in the same category as global warming.

If that stupid Turbo thing actually worked then every single truck manufacturer would have them as standard equipment so they could boast higher fuel economy. I'm sure they have tested it the right way and came to the conclusion that it's a bunch of crap.

 

I am glad that it worked out for you. I hope that you get as much wear out of yours as I have mine. Which brand did you buy?

 

Well, it's your money, you could believe, what you want!
BTW, that tire has a best ice and snow traction, if you are so much concern about it.

Not "documented" but came from a person, who knows what he is talking about....

The trailer tires are Double Coin RT606. Drives are Emtrac. He didn't have enough Double Coin drives in stock. The Emtracs have 30/32" of rubber. Should last a little longer although initially all that rubber may hurt fuel economy, I guess.

 

I haven't tried the Emtrac tires. So far I have had good service out of all the tires I have gotten from them. I would be interested to hear whether they wear as well as the Double Coin.
