When changing the STOCK POS Michelin tires, Have you noticed a DROP in MPG?

csmeance

when changing to or from? and if from, to which tire? I would make sure that the proper size is being used, and the PSI is set correctly.

Changing from, to any other tire, the OEM have a very low rolling resistance if I am correct, and I am making sure that when people move to a different tire, have they noticed the drops in MPG that I have when I moved from the Same exact tires on my Volvo.

I will gladly give up a few MPG to get rid of the "STOCK POS Michelin tires".


BTW - What is "rolling resistance" and how do you know if a tire has more or less?

Just out of curiosity.... I have been told by many people who "Know tires" that Michelin Pilots are some of the best tires made. Im not trying to be ignorant, but are you saying that the tire itself is bad because it is Michelin or because it does not perform as well as a lower profile, higher speed rated tire? Just curious.

No, I'm not saying ALL Michelin tires are garbage But this particular Grand Touring Tire (Michelin Pilot HX MXM4) from Michelin is garbage. And they must have been talking about the Pilot Sport tires(GREAT TIRE), I could not ever hear anyone say these Michelin's are the best tire money can buy, because they SURELY are NOT! Maybe if the price was right; lets say 65 dollars? Then maybe, but at $200+ a pop, Shop elsewhere.

Rolling resistance, sometimes called rolling friction or rolling drag, is the resistance that occurs when an object (e.g a wheel or tire) rolls. It is much smaller than sliding friction except for special cases like ice skating. It is caused by the deformation of the wheel or tire or the deformation of the ground. It depends very much on the material of the wheel or tire and the sort of ground.

Also the manufacturer will specify if they are, or aren't of low rolling resistance.

But I will say that I think the Sports are little high priced in certain sizes, But still a really great performer.

I've never much liked the MXM4's either. They seem to wear fast and handling goes quickly downhill. In reality they are a good tire, but IMO, over-priced compared to the many others that offer better overall performance.

I am currently infatuated with the BS 960 AS Pole Positon.

A year ago last spring, I replace my stock OEM EL42's on my '04 manual TL with Michelin Pilot Sport A/S tires. Immediately I noticed a significant difference in the rolling resistance.. the Pilots have a greater rolling resistance than did the EL42's which are classed as Grand Touring tires. The resistance was enough to keep my TL from coasting out of my garage backwards when in neutral.. the EL42's would do this.

Around town mileage dropped around 1.5 MPG and highway mileage dropped close to 2 MPG. However, handling is much improved over the EL42's, as is resistance to hydroplaning (never had that in this car but had it severly in my '02 Altima SE with the EL42's).

I would think that changing to any non factory equipped tire would result in slightly lower fuel economy as each manufacturer is trying to obtain the best mileage possible. Got to say, I'm not one to try and extract ultimate fuel economy out of our cars, but am one to put, what I feel are the best tires under the cars, so on the TL I went to Yokohama S.4 245's. Couldn't tell you the mileage difference as I've never checked.

I recently switched to Yokohama ADVAN S4s about a month ago. When I checked my first tank, my mileage went down to 24 mpg from the usual 25/26 mpg. Upon checking my air pressure, I noticed they were all at 30 psi - lower than the 35 psi front/32 psi rear I had on the OEM Michelins. Now that I have them a the correct psi, I'm now getting 25/26 mpg again.
