I am failing to make the connection between underdrive pullies and tire size.Isnt it if you have a desent size lift and desent sized tires were they hurt you (bigger tires are harder to turn)? But, if your stock with stock sized tires your fine?
I think he's referring to the underdrive pullies slowing down the power steering pump, combined with larger harder-to-turn tires.....I am failing to make the connection between underdrive pullies and tire size.
The bigger/wider the tire and the more the wheel is offset, the harder it is to turn from side to side. Underdrive pullys slow the power steering pump pully. This reduces it's output at any given RPM.GTRider245 said:I am failing to make the connection between underdrive pullies and tire size
Umm, ya. They suck for anything unless you're turning constant 2000 rpms.Under drive pulleys are a poor idea on road only vehicles.
They are a horrible idea on an off road vehicle.
Reduced alt output
Reduced power steering
Not things you want for a lifted Bronco on 35" +/- tires with offroad lights/welder/on board air/ect, on a trail on a HOT August afternoon.
