Would snow tires on the rear cause more rolling resistance and worse fuel milage??
I have a '84 F-150 w/ 351W & C-6, only getting abot 6-7 Mpg.
Just replaced the motor and rebuilt the carb. Same milage before and after. I'm not sure what to check next. Thanks for any help.
it's been my experience that adding rougher tires (same size as previous set) of course does slightly decrease gas mileage, due to the added rolling resistance like you said. I would guess your gas mileage problems are coming from somewhere other than tires if it is that low, unless you have oversized tires. What size are you running?

I am a commercial tire dealer and retreader, so I know of what I speak. Snow tires are made of a softer compound, this provides better traction in both wet and dry conditions. They will not wear well during the warm parts of the year and should be taken off when winter is over. Snow tires do have quite a bit more rolling resistance than all seasons and the rolling resistance goes up as the tire gets warmer. Whether they get warm because the weather is warmer or because you are driving down the highway heating them up.
rcdague, I am pretty sure I know the answer but do bigger tires with Mud tread and such have softer rubber there for they will wear down a lot faster? Thanks.
