A wheel lug nut torque chart indicates the proper amount of torque, or twisting force, to apply to the lugs nuts found on vehicle wheels. Mechanics need to apply proper torque when tightening lug nuts to ensure damage does not occur to the wheels.
The appropriate torque for lug bolts varies depending on the vehicle and can range from 50 foot-pounds to 350 foot-pounds. The correct torque specifications for a vehicle can be found in the owner's manual, at a vehicle's dealership or in a repair manual for that specific model and year.
A lug nut is one of the fasteners that attach a car wheel to its hub. A car wheel has four, five, or six lug nuts depending on its make and model.
The effect of the wheel lug torque depends on how much the applied torque deviates from the recommended car torque. While overtightened lug nuts cause vehicle vibration during braking, overstretches and weakens the wheel studs, undertightening causes wheel wobbling and unbalance during driving. Corr
A torque specification chart explains the correct torque for a variety of nut and bolt types. The charts tell mechanics, builders and assembly workers how to tighten each nut and bolt for maximum efficacy. Most charts identify bolts or nuts by size and the number of threads per inch. Depending on th
Auto mechanics use torque specification charts to ensure that fasteners of all types, especially bolts and screws, are neither too tight or too loose. Proper tightening is critical for wheels, as well as engine and transmission parts that rely on a gasket to contain a fluid.
Use a tire torque chart by finding the make, model and year of your vehicle on the chart and reading the appropriate torque measurement. The torque measurement is the amount of torque required by each of the wheel's lug nuts. Too much torque over-tightens the lug nut, potentially stripping the threa
Most frequently, use a lug wrench or tire iron to remove lug nuts. Alternatively, use a spider wrench, which is a cross-shaped tool with varying sized sockets on each tip.
Discount Tire and the Yellow Line Stores have wheel torque charts on their websites. The chart lists the model of the vehicle, its year of manufacture and its wheel torque specifications.
Portland Bolt & Manufacturing Company, Bolt Depot, Imperial Supplies, Engineers Handbook and Federal Screw Products provide torque charts as of 2016. CNCexpo.com, Allied Systems Company, XRF Reduced Friction Chassis Parts, Engineers Edge and Repair Engineering also provide torque charts.
