put nitrogen in them, you will get better gas mileage and take off is a bit better.

I inflate my tires a couple of pounds higher than recommended to reduce rolling resistance.

I run 40 psi min, 52 psi max on my cars. They roll much better that way.

I notice degraded handling more than lost MPG from underinflation. Especially the little sports car; steering (not power assisted) gets heavy.

I have noticed slight differences in mileage with under inflated tires, esp. on my bike. Handling also suffers when your tires are way under inflated (more than 10 PSI below the recommended) unless you are 4-wheeling

more psi = better gas milage BUT uneven tire wear and decreased traction on wet roads. it's a balancing act. My 2013 Fusion recommends 33 but I keep em at 46 psi cold and just recently got 55.21 mpg on a full tank real world

One poster writes: I keep the Michelin's at 38 front 40 rear cold... ______ I put more pressure in the front tires than I do the rear because more of the weight is on the front wheels. To get the best gas mileage and the beat tire wear, it's important to reduce the amount of tire flex. The tire pressure used should be a function of the the amount of weight the tire bears.

Yes, I do a walk-around before I take off, most every time. I keep my tires around 40 psi, well below the max tire rating but about 8 psi above manufacturer specs.

Yeah...People Never check their Tire and THINK about it, It's the ONLY part of the CAR that actually touches the ground...The MPG is worth the weekly tire check,But Daily tire checks CAN SAVE YOUR LIFE!!! I visually check my tires everyday and gauge test them ounce a week...Don't forget to ALSO check the SPEAR TIRE!!!!

I see the same thing. One of my cars is quite consistent with temperature changes and the other car may swing 5-6 psi.

I check often. I over inflate slightly and see a good 3mpg increase at highway speeds. Car says run 28psi, I run 36psi. I always see cars with a really low tire. people do not check pressures often enough which costs $$$ in poor mpg and tire wear. Not to mention the safety factors.

Yes, amazing how many People drive with low tires? Then they're surprised when it blows out. All out blame a higher power, I know a guy who blew 3 out of 4tires off his sailboat trailer on a 3hr trip (1/2 way home) He gave me a dum look when i asked if he checked the pressure b4 he left?? duh!

I check the air pressure regularly, even though mine do not lose any significant amount over time. Occasionally have to top up a pound or 2. I have not noticed a difference in fuel mileage since they are never left to go down enough to make a difference.

Good Morning,
I agree with you ldheinz when you say, "...tires cost a lot more than the used to...". Last year tires increased in price nearly 30%. I check mine twice a month, faithfully rotate them and maintain the vehicle manufacturer's inflation recommendation. In general, not always, this has lead to safe travel, long life and excellent handling. You are right, tires are expensive to replace, but they are much better in quality than the old bias ply tires.
Take care :-). MGY
