I put an add on Craigslist last week when I found out to replace my 305-50-20 tires it would cost me $400 a pop. Two days later a guy replies and says he has a 2 month old set of ProComp Mud Terrains on ProComp wheels. I contacted him and Saturday we made the swap. I love the tires and even though the wheels are a bit old school, they are growing on me and my gas mileage actually went up about 1.5 mpg! Let me know what you guys think. I will post some pictures of the entire truck later.

OLD:


NEW:

Those look soo much better.

Yeah.....waaaay better.

i agree, 20's are nice on a car but you need the rubber to make a truck look right.

Good boy! 20" wheels have no business on a 4x4, unless it's a huge lifted, solid front axle 4x4 with like 38" or larger tires...

show some pics of the whole truck, i wanna see it..

Let us know if your gas mileage drops and how much it droped

Just like what im wanting to trade my 20s for ...

What about this situation would cause an increase in gas mileage? Anyone?

Just curious.

yea they look nice... im interested on the science of the improving gas milage too...
