Gas mileage and tires

[morpheus]

Does anyone have any links, or knowledge on how much different tires may affect gas mileage.

 

I'm not refering to tire size specifically, as we all know that bigger trucks and bigger tires will eat fuel, what I'm getting at is more along the lines of different manufactures of the same/similar sizes.

 

Also wondering if load range of a tire would affect mileage too. - ie: higher load range = more rubber = heavier tire?

I actually got better MPG with my chunky BFG MTs, than with BFG ATs, same size.

not exactly what youre looking for... there is this one for different tire sizes and speed... http://www.miata.net/garage/tirecalc.html

 

I saw one about tire size and how bigger rims/tires affect gas mileage and braking... I'll see if I can find it again.

I use that calculator all the time, great tool.

 

Basically looking for if you run 5 different 31x10.5r15 tires, is there anywhere that would tell you of the 5 which would have the best MPG rating.
