Just switched from my Sahara wheels 18" with 33" Duratracs ( Load D) to a 15" Wheel and tire package with 15" MB TKOs & 35x12.50x15 KM2s ( load C ). I didn't notice this at first but now I'm a little worried about the load range C tires. I guess I'll see when they show up this week.

Did I screw up? Any negatives on the load C?

E range tires tend to be heavy by the nature of thier design (thick rubber and numerous plies) so I do think the heavier tires cut down on mpg and even accelleration a bit.

Why would there be a fuel economy / milage rating differance between C,D or E rated tires? The outer tread componds are all the same ( within the same make / model tire ).

JK-jeepit - If you need off-road capabilities, go E - rated. But the lesser rateings will be more road friendly.

I personally think for the sake of argument that a 33" tire that weighs 30 lbs vs a 33" tire that weighs 60 lbs will get better mpg in dd conditions. That all said my E rated tires are every bit as smooth as my P rated stock tires were.

So far for my research on new tires it looks like most tires that come in the larger sizes come in an E rating...
at least the ones I've looked at anyhow...
So I can see why most don't have a problem with E rating tires..
