Would you get better gas mileage with thinner tires on your car or truck?

I use 225/70 14 on my truck and wondered if I can save more gas if I reduced my tires’ thickness to 215/70…

No!

The thinner tire will probably not reduce the area that touches the road surface. What it looses in width it will make up by increasing the tire print the other direction.

This is due to the weight of the car.
…..which leads me on to the next topic:

Reducing WEIGHT is the way to save gas. How much trash and crap do you have laying around in your truck? Getting rid of that will make a much bigger difference.

It could make mileage worse with some tires or road surfaces. You’d have more weight per square inch than the old tires. Not that it’d make even a 1% difference anyhow.

i think it would helpbecause if u look at a hybrid they got little little little tires. and yes it is lighter but if u put huge tires on it, it would get worse miledge

Tire print on the road?? No that is not true at all. Just because its a thinner tire does not mean that the weight of the vehicle is going to put a load on the tire so great that it will stretch and spread the tread out. As long as you get a tire with a weight rating large enough for that vehicles gvwr it should be fine. It WILL increase gas mileage but but a VERY little bit. That is because a thinner tire will reduce a little bit of weight (depending on how thin you go) But honestly its not worth a new set of tires to save that little of amount of gas.

hi
this is the kind of stuff that is talked about online if you look up “save money on gas” or something like that on Google… all these kinds of tips are largely inconsequential
if you remove the dead body uh… excess weight from your trunk you might save $150 per year on gas expenses… something like that unless you are driving A LOT!.
they say that your a/c will cause a drain on your gas mileage but it is actually better on the freeways then driving with your car window open and having that drag aka wind resistance.
so just skip the whole subject.
But i do invite you to see all of the happy faces in the videos at http://bestmpg.info
There is hope and there is a solution.
Best
