anyone know of a good site that has good prices and also displays the weight of the tires???

 

You shoudn't notice a lot a change it will be so small you wont even notice it.

 

I'm with them..you won't notice much change with such a powerful engine. I had 255/70/16 on my Ranger and upgraded to 265/70/16 BFG AT's and since they rubbed got a much heavier steel wheel...my miles per gallon dropped by about 1 on that. Picking up the BFG and steel wheel was probably double the weight of the 255/70/16 on the stock aluminum wheels too. I definately noticed some sluggish performance though, but that was on a 4.0 six-cylinder with a manual transmission. I bet with the v8 and an automatic, you wouldn't even notice.
