Wheel weight and performance

Hi all am looking at new wheels and I am between the fn six shooters and the 4Runner pro wheels. Looks like the fn are 3lbs lighter. Is that enough weight to make a difference? Will be jumping up to 255/80r17 so going to be gaining weight there. I remember reading somewhere that a certain amount of rolling weight equals 100 lbs in the bed. Anyone know that number. Thanks

 

not if U mount bigger luged tyres..................i dont think 3 pounds equal 300

4 wheels equal 1200 Ur almost at max bed weight

 

Get the ones you like and fuck what they weigh.
