Would gas mileage really be reduced a little bit?
I'm curious. What makes you think your mileage will change?

Im wondering if thinner tires would cause less friction/drag therefore increasing mileage...

If there is no adhesion between the tires and the pavement, then the coefficient of friction (rolling) should not vary with contact area. And if it does, the change will be negligible in terms of mileage improvement.

There would be a slight reduction of friction between the tires and road surface. Slight being the key word, so slight that you would never notice it in a fuel mileage calculation. However the reduced surface area of your tires may Greatly impact your traction. Reduced traction will go unnoticed until you really need it. Situations like emergency braking, an evasive move in traffic, poor weather, will all bring it to your attention. Sure the ABS will still activate correctly but it will have just that much less area to work with. IMHO it's not worth the trade. As for the tires fitting the rim, any good tire shop would be able to tell you, I really don't know. As for the spare, it's the same age as the original tires, I'd leave it as is, as a spare. Good luck to you and I hope you can find a good deal on some tires.

I wanted to see what others have recently been getting with the latest models. I currently get about 13-14 City and 21-22 Highway going about 65-70 MPH. Kind of dissapointed with city figures but when reviewing others mileage forums it could be worse. Mileage computer has definitely cured my lead foot as with certain techniques like coasting and keeping RPM's low I can get up to 15+ in City driving.

98 Explorer Sport, 4.0L SOHC, 120,000 miles, 13 MPG in town, 16-17 highway. I think that stinks. I like everything else about this vehicle, except that the rear springs sag a bit. It even tows my 19' boat well. Cruddy mileage. I changed to synthetic oil recently, so I hope that helps a bit. I think it had 10W-30, now I put in 5W-30 syn.

I drove the truck from 84,000 - 106K miles.
stock 4.0L 203 hp V6 16/21 MPG
After adding:
Flowmoaster Catback system
removed radiator fan and converted to 16" Hayden electric fan
cold air intake
new plugs/wires
TPS Sensor adustment
ended up getting 19-20/25-26 according to the self installed information display i installed from a 4 door model.

hey coach, If you never tried using a 100% synthetic oil, that will help your mileage. I use Amsoil now which I believe is a better oil than Mobil1 and it's close to .50 cents cheaper per quart depending how much you would buy. Synthetic oils are produced here in the U.S.A. and not imported from the mid east. If you have replaced tires, Did you get a heavy tire ? Any one who would buy Goodyear Wranglers Silent Armuors will get less MPG. The set I got for my mothers 2003 explorer, very seldom will you get 16MPG with good gas. It use to be with bad gas the least you got was 16MPG with the Michelin cross terrains. Maybe you need to get different gas as now ethenol is everywhere at the pumps mixed in the gas of 10% mix. Some people now say that ethenol has alot of less MPG we all are getting. Who knows. Now I'm confused.

nfntruth...... You made a smart choice using 5W-30 synthetic oil. If everybody would use it, these people that hate us would not be getting our money. If your explorer uses oil, and you believe and see that it still is, wait after 1500 to 2000 miles and change the oil and filter again with 100% synthetic oil. If it does not use oil, I would change it all again after the first 3000 miles on your first synthetic use. You will see the gunk & slime the other oils creates when you drain it. I had a 1986 T-Bird and it used oil. After I changed the oil and filter after 1500 miles. At 26500 miles, I could'nt believe what that oil looked like. I drove it for 12 more years changing the oil one time every year, and I put 170,000 more miles on it. it was a 3.8 V6 with 25,000 on it before I switched to synthetic oil. Hope all this helps you or anyone else.
