Have a '96 Cherokee 4.0 auto running on the BF Goodrich A/T KOs, and I'm thinking about changing over to a street tire, if and only if it will save me the cost in gas over the next two years that it costs to buy em.

So what's the popular opinion? Will a set of say Michelin LTS M/S Highway All Seasons save me say $600 over the next two years, over my BFG A/T KOs?

I drive about 12K miles a year 99.9% on pavement.

Consumer Reports did a recent study of fuel saving tires. They claim that some tires can save you up to $100 in fuel savings per year. Michelin and Goodyear make tires rated well.

Rolling resistance accounts for about 4 percent of a vehicleÆs fuel use in city driving and about 7 percent on the highway, according to the U.S. Department of Transportation. Replacing high-rolling resistance tires can result in as much as $100 in annual fuel savingsùand potentially hundreds of dollars over the life of the tire.

If you're only talking about the next two years it doesn't sound like the cost/savings makes any sense.

You'll have to subscribe to CR online to rear the reviews and related articles.

Keep in mind, those tests are done i a controlled environment.

In real world, you will have road and weather conditions that have a major effect on fuel economy...

A simple way to improve tire wear and fuel economy is keep your tires properly inflated.

Michelin tires are made by BF Goodrich...

IMHO, there is not a lot of difference between All-Season and All-Terrain.

All-season are generally associated with passenger cars where the AT are generally associated with light trucks.

Personally, I would go with the AT as they are a 3-ply sidewall.
