dem00n Posted July 27, 2010 Share Posted July 27, 2010 I just saw an ad that putting these certain tires save you 160 gallons of gas? How so? Link to comment Share on other sites More sharing options...
milod Posted July 27, 2010 Share Posted July 27, 2010 They made a big deal about radials saving from bias ply too. A lot has to do nowadays I think with tire pressures. I run my Jeep with much higher pressures than I used to run my cars and get reasonable mileage for the size vehicle and how/where I drive. My understanding is it has to do with how much energy is lost to the tires themselves. m Link to comment Share on other sites More sharing options...

DiamondJig Posted July 27, 2010 Share Posted July 27, 2010 Buying a new Gibson will save you on gas too. You'll stay home and play and not drive around as much Link to comment Share on other sites More sharing options...
TommyK Posted July 27, 2010 Share Posted July 27, 2010 Generally speaking, soft and cushy is offset by wasted energy which translates to lower MPGs. By raising tire pressure, above the manufacturer's recommendation, you make them harder and less resilient, therefore your MPGs go up, at a loss in ride comfort and tire longevity. My guess is that the gas saving tires are made stiffer and less cushy. They may also be using a more fuel efficient tread pattern. But at what cost? Ride Comfort? Traction (i.e. less stability in turns)? Shorter tire life? 160 gals over the life of a set of tires? $3.00 * 160 = $480.00. That should just about pay for the tires. Where do I get these? What are they comparing the gas mileage to? Under-inflated bias plies? or their 'lesser' model tires? Link to comment Share on other sites More sharing options...

canon_mutant Posted July 28, 2010 Share Posted July 28, 2010 There actually is a science behind rolling resistance based on a number of factors including tire tread pattern, tire width, tire weight, tire material compound, etc. I would suspect the 160 gallons saved is over the expected life of the tires. Over a 60,000 mile tread life that would require a little over a mile per gallon better fuel economy. That's within the realm of doable. Link to comment Share on other sites More sharing options...

Steven Tari Posted July 28, 2010 Share Posted July 28, 2010 Yup and the lower the pressure the better the traction (to a point) but the rolling of the tire becomes harder to do and looses its ability to be efficient. When I used to race the camaro I used drag slicks (Mickey T's) and only ran 10psi and those tires would be real sticky and get ya down that track but for sure not a tire to use on a real world/road environment. We used a ammonia, water mix to get our's real sticky. Turn them over one time at the line, then we were ready to race. But that was in "74".
