Can you over tighten wheel bearings?
“Excessive preload will cause excessive friction and the bearing will run hot, compromising lubrication and eventually leading to flaking (material coming off) at the large end of the rollers/races,” he says. “On the other hand, adjusting the bearing too loose causes excessive looseness and vibration in the system.
What should I torque my wheels to?
New wheels should be re-torqued after the first 50 to 100 driving miles.

| 12 x 1.25 mm | 70 – 80 | 8 |

What happens if you over tighten wheel nuts?
If the wheel nuts are too tight, they can cause severe problems such as stripping the fastener threads or stretching the wheel studs. They could also warp the brake drums, brake discs or wheel hubs. With loose nuts, meanwhile, there’s a small risk that the wheel could come off while you’re on the road.
When should wheel nuts be checked?
Automobile clubs recommend checking the seating of the nuts after 50 to 100 kilometres and retightening them whenever necessary. The reason for this is that the wheel bolts can loosen over time, meaning the wheel is no longer seated as tightly as it should be.
Can over tightening lug nuts warped rotors?
Overtightened Lug Nuts and Brake Rotors Over-torquing a wheel can result in a warped brake rotor and possible hub flange damage. Rotors get extremely hot and improper, and over-torquing a wheel can result in warpage as the rotor heats up and cools back down in service.
What happens if you dont torque wheels?
To compensate for any possibility of loose nuts and bolts, technicians often are tempted to over-torque the wheel hardware. Too much force can cause a technician to strip threaded fasteners or stretch bolts beyond their limits, which can result in loose nuts or cause the bolt to crack and break.
Do I need to re torque my wheels?
Whenever you have new wheels and tires fitted to your car – for example, you’ve done the sensible thing and switched between summer and winter tires – it’s essential to have the lug nuts retorqued after the first 50 kilometers.
Can you change a tire without a torque wrench?
A torque wrench is not explicitly necessary; the spare jack and tire iron that come in the trunk of every car are sufficient to change a tire in normal cases. If this was the case, car manufacturers would have to start including torque wrenches with the car in the event of a flat tire.
