Gas saving tires

Automakers have developed a budding affection for "low-rolling-resistance" tires to squeeze a few extra miles per gallon from every model. "They are putting much more emphasis on fuel economy than ever before" when it comes to picking tires, says Mike Martini, president of the Bridgestone division that supplies automakers.

Tires Saving Gas

I know I am not the brightest bulb in the house but how does increasing horse power help this car in achieving better mileage? I doubt that the increased the burn efficiency to get it thus it was done at the expense of burning more gas then required by the last yeas model.

I am glad to see that the changes they made in the transmission and tires has offset this but why not place the old motor in this rig and increases it mileage more substantially.


Second yes tires have a huge influence in millage. But you as a drive must stop and think do I drive more on the highway or in city.

Here is how it work through out all those gas guzzling low profile 60 plus series tires get back to a normal size tire say 75 or 70. Yes you give up some grip in summer but gain some in winter. Now why on earth are you running 16 inch rims on a tiny car? Style that it. So place some 14 inch rims on it so the motor does not so hard on low rpm to get moving then you can also reduce you required HP. Result less gas used to move the car at normal road speeds. This really helps in town.

If you drive all highway then start stop energy wasted is not an issue and the big tires(not wide just tall) roll and keep rolling easier so you can reduce the power required to keep the car at that speed.

So improving the tire shape and design to increase mileage is great but perhaps auto makers need to start putting on more sensible tire also.

Driving both on the highway and in town I know that my car gets decent milage. I would want one the gets better but I am averaging 28 to 29 per gallon now. I am using 16 inch tires because that is what the car came with. I can not go to a 14 or 15 inch tire so I have to stick with the 16. I think making sure my tires inflation is at peak level will help me with gas milage too as the required surface is all that is on the pavement. This reduces friction and improves gas milage. I do know that I have to buy new tires this fall. I will be looking at a tire that will fit my car and help get me better milage.
