We had Michelin Harmony tires on our 2001 Dodge Intrepid, {142,000 miles on odometer}. These tires lasted 52,000 miles, before one rear tire sidewall blew out. These tires were about 4 1/2 years old and had some tread left. We replaced these with 4 Goodyear Viva Authority Fuel Max P225 60R 16 tires, at Walmart. Immediately, I noticed the much quieter ride and the car tracked well on the highway at 65 mph. The steering wheel did not need to be constantly moved to keep the car on the road.

We read as many reviews about LRR tires and side by side LRR tire comparisons like "InAutoNews" May 2012 review of Low Rolling Resistance tires on a Toyota Prius. We found that Michelin did not make LRR tires in our size, which were used on this Prius. So we were left with buying Goodyear LRR tires. But Goodyear LRR tires were about $38 less per tire than the cost of Michelin LRR tires.

We kept track of the miles and gasoline used before the Michelin tires were replaced. It was about 27.9 mpg highway. After installing the Goodyear LRR tires we got around 28.9 mpg.

Likely the actual mileage increase would be around 2 mpg. Why? Because new tires travel 1.3% more miles per indicated mile on the odometer, or about 70 feet per mile indicated. The odometer records tire revolutions, not miles traveled.

The circumference of the new tires is about 1 1/2" longer than the old tires. This means the tire travels about 70 feet more, for every mile indicated by the odometer. On 220 mile trip, the tire would travel 3 miles more, even though the odometer indicated the same 220 miles traveled. This compared with older worn tires with maybe 1/4" tread wear, or 1/2" smaller diameter, and therefore approximately 1 1/2" less circumference. Simple!!!

Wife says, the security of new tires is also worth it. Note: The wheel/tire with the least rolling resistence is actually a steel rimmed wheel on a steel track, like the railroad uses. Traction would be terrible, the ride harsh.
