Do lug nuts need to be torqued after new tires?
Lug nuts must be torqued to the manufacturer’s recommended values, and they must be re-torqued to those values after driving approximately 50 to 100 miles on your new tires after the tire service. Both under and over tightening can be dangerous. To tighten lug nuts correctly, a torque wrench is required.
Can you torque lug nuts while car is on the ground?
Actually important thing is to hand tighten in a way to make sure the rim of the each hole is resting on the shoulder of the nut not on the thread of screw when car is on the jack. Then tighten with torque wrench in a criss-cross pattern. Lower the jack and torque wrench it to spec. Then re-torque or checked later.
Is it normal for lug nuts to loosen?
Temperature. Most wheels today are made of an aluminum alloy and are held to the hub with steel lug nuts. These two different metals expand and contract at different temperatures which can cause them to loosen as they heat up and cool down. This can cause lug nuts to loosen even if they are torqued to factory standards …

Run the lug nuts in with your favorite tool until snug, but no more. Tighten the lug nuts in a star pattern twice, smoothly applying force until the wrench clicks, but no further.
How many foot pounds of torque do I need for tire lug nuts?

| Hardware Bolt or Stud Size | Typical Torque Range in Ft/Lbs | Minimum Number of Turns of Hardware Engagement |
|---|---|---|
| 14 x 1.25 mm | 85 – 90 | 9 |
| 7/16 in. | 70 – 80 | 9 |
| 1/2 in. | 75 – 85 | 8 |

How tight should wheel nuts be NM?
The optimum torque value for your car or mounted rims can be found in the vehicle manual. It depends on the car model, rim size, design (aluminium or steel rims) and number of bolts. It is normally between 110 N⋅m and 120 N⋅m.
Are torque specs important?
Though often overlooked, torque specs exist for nearly every nut and bolt on your vehicle. No matter the project or repair, if you are tightening a bolt, the bolt has a specific pressure at which it should be tightened. Torque wrenches are important to ensure a balanced rotation of a component in relation to its axis.
