Failing to find the owner's manual, you can try these options, but they are less reliable:
* A reputable online parts store: Websites like AutoZone, Advance Auto Parts, or NAPA Auto Parts often have online catalogs. Entering your vehicle's details might provide the torque specification. However, verify this information with another source if possible.
* A local mechanic or tire shop: They will likely have access to torque specifications for various vehicles.
Improper lug nut torque is dangerous. Over-tightening can strip the threads or break the studs, while under-tightening can lead to wheel detachment while driving. Always use a torque wrench to ensure accurate tightening.
