10 ply vs 4 ply mpg loss?

how significant is the mpg loss by going with the 10 ply tire? Everyone acknowledges it, but no one really throws a hard number out.

 

In all the cases I know of, they aren't really "10 ply", but load range E 10 ply RATED. Probably a lot heavier than a C range tire. May or may NOT have aggressive tread. That burns gas too, I've heard of"E's" taking 5 or 6 MPGS or more...Seen 'em take little to nothing.

 

It's not just the weight of the tire but also the design of the tread. The weight of the tire is not going to make as big a difference as the tread design. If you went from a 4 ply to a 10 ply of an identical tire size and tread pattern you probably wouldn't notice a difference in fuel economy.

 

Depends on driving style too. Lots of stop and go driving will be more impacted by heavier tires.

I have 10 ply Michelin MS2's and 10 ply Cooper ATW's. Both are pretty good for MPG's.

The weight of different tires can vary greatly. Consider he weight when choosing. Also, if you want 10 ply (rated) tires without the weight get a 235/85r16 (or 235/80r17). Same overall height as a 265 but a little narrower. Gives it that military / utility look and getter traction in anything you don't want to float on. Way better resistance to hydroplaning or losing control in heavy slush.
