I realize with every inch in diameter tire size, you loose power/torque, but just how much??. Does anyone have a chart that depicts estimated ratio of power loss to tire diameter?
I'm buying a '07 F150 4x4 Lariat Screw for more pulling power, but don't want to forfeit power for 'look'. Am I concerned about something that is not really measurable? Thks in advance!

 

You notice a difference. How much depends on how your powertrain and how you use your truck. What I mean is someone with a V6 that tows/hauls a lot is gonna notice more of a difference than someone with a 5.4 that never tows/hauls. I just replaced my 33's with 35's last week. The biggest difference I noticed is that I can't spin the 35's from a dead stop. However, I have the 5.4 and never tow/haul.

 

I bet those 35s look nice on that truck
