The tire theory of setting to not-too-high a PSI is the tire pushes back against the road after it goes over a pebble. Stiffening the tire interferes with that. It stands to reason that stiff shocks might too.

Nothing more. Nothing less.


Yes, but I would add that dissipated energy (heat) is wasted and it costs fuel, but I do concede that the amount is in all probability immeasurable.

Until you can convert the energy from the bump into a way to propel the vehicle, it has zero effect on the fuel economy. Buying a lighter car would help more than anything.

Fascinating. I always thought the harder the tire the better for MPG, but, this makes sense. He's to hoping my gas mileage won't be plummeting with my sporty stiff struts. whistle

If you make force vs distance diagram you'd see that what you gain is easly lost in the noise. Ed

The money you save in gas with stiffer shocks will probably not be enough to cover your doctor bills from back problems down the road.

Shocks and springs are not powered by the engine, nor is any energy from them used to move forward.
