Thread: Tyre rolling resistance?

I doubt you will be able to find comprehensive data anywhere.

As long as you aren't fitting rag tyres like SATs I don't think you will find much increase in fuel consumprion - 10% at most).

Wikipedia has a good explanation of rolling reistance: [ame="http://en.wikipedia.org/wiki/Rolling_resistance"]Rolling resistance - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Rolling_Resistance.PNG" class="image"><img alt="" src="http://upload.wikimedia.org/wikipedia/commons/thumb/c/c3/Rolling_Resistance.PNG/220px-Rolling_Resistance.PNG"@@AMEPARAM@@commons/thumb/c/c3/Rolling_Resistance.PNG/220px-Rolling_Resistance.PNG[/ame]

Thanks for advice,

Existing tyres are Michelin XPC 750 x 16

Thinking of fitting Goodyear Wrangler MTR 235/85 R16 on Wolf wheels

I do know of a couple of cases where people have made similar changes and have noticed 4 mpg difference.

I have 285/75-16 MTRs on one vehicle and 255/85-16 Maxxis Bighorns on another (similar tread pattern but much cheaper than MTRs). I get good economy from both vehicles, but I do run them at ~45 psi on road.
