I was getting around 280 miles per tank 6 months ago. I bought new tires (same size i had), and had our alignment adjustment, new battery and air filter all within a couple of weeks and now my car only gets about 240 miles per tank. I took it in to the dealership to have a check done on the car, feul injector.... sensors all that and they found nothing wrong. Does anyone have an idea what is wrong?

Tire pressure is a big difference. The less air in the tire, the more of it is making contact with the road, therefore lower gas milage.
Driving conditions, Wind, how you drive it. Theres a slew of other factors. It shouldnt really be anything with the tires if they're exactly the same.

Do Tires Affect Gas Mileage

Tecnically yes, new tires will influence your mileage, but it is so slight you would never see the difference. Are you driving at the same speeds (interstate speeds verses state highway speeds)? Are your trips shorter or are you in more stop and go traffic? Are you using the defroster more right now? The defroster will also run the air conditioner to remove moisture from the air and this will effect your mileage. From mile range your giving your using about one and a half to two gallons more fuel. It is possible that your car is not quite level when fueling or the station may have replaced the nozzels and this may be making the nozzel click off slightly sooner and therefore your not quite filling the tank. Try another gas station just to see what happens.

There are two effects from putting larger circumference tires on your car. They will usually be wider, so more friction (resistance) and weight, reducing mileage a bit. Because of a larger circumference, they will travel further for every turn of the driveshaft, increasing mileage a bit. I don't think you'll see much difference, if the change is small.

If the old tires were bald and the new ones have deep tread then even though the size on the sidewall is the same the actual diameter of the tire will be larger on the new tire and covering more distance with one revolution putting your speedometer and odometer slightly out of whack compared to the old tires. Your actual fuel mileage might be the same but whats reading on the odometer might be different.

Yes it does it is called restanice to the road
Sticker tires get worse gas milage, hard tires better
that is why some cars OEM tires are just avg. it is becuase they are looking for the ones with the best gas millage
I know that the govt wants them to put it on the side of tires, but we do not want people only to look at that no. when people buy tires, becuase all of a sudden you could have a tire that is unsafe but gets great millage

nothings wrong-the new tire(even the exact tire) has a greater diameter because of all that nice new rubber and therefore covers more ground per revolution.the tire is actually turning slightly slower and fewer turns affects the speedometer that just counts the number of times the wheel turns and shows it as speedand mileage.
think of it this way-your car will show less mileage at trade in time(putting giant tires on my truck threw my speedometer over 10% and i was going over 72mph when the old speedo said 65!

What will change your mileage...?
> weather
> "lead foot"
> tire pressure - under inflated in this case
> bad gas - make sure you get the top 3 - Chevron, Shell, or 76
BTW...They aren't the same size...even the same brand and tread will be a bit bigger. The ones you had were worn.

Yes, different tires will affect fuel economy. Some tires are designed to be better fuel efficient than others. More aggressive tread will usually lower economy because of their parasitic drag from extra traction. Tire pressure should be around 33psi for optimum economy too.

yes and no.
there is more factor related to millage.
tire diameter is only one of a thousand
driving "in"city traffic
driving highway. empty roads
type of gas used
spark plugs(used?)
even the differential gear oil take part on the whole picture.
40 miles a month? I don't think is noticeable difference.
