Touque specs on a 18 inch rim

[hunterclavel]

I have a o2 galant 4 cyl and i but some 18's on it and i was wondering does the torque spec change or do i use the stock setting

[Reelax]

if you are asking about the amount for torquing the lug nuts, then same as stock.

Thanks

Just make sure that you DO NOT use any lubricants on the lugnuts or wheel studs.

Dont wanna thread jack, but why not use any lubricants? I used some anti-seize on my studs a few months ago.

Manufacturers only supply a 'dry torque' specification. Using lubricants (anti-seize or otherwise) will cause improper 'wet' torque values. This means in general that your lugnuts will be overtightened, if you are using lubricants. Although, you CAN use anti-seize on your hub centers, where most problems come in anyways.

But Tirerack.com has the best explanation I've seen anywhere:


IMPORTANT!

Proper installation requires that the wheel lug torque be set to the recommended specification for your vehicle. Sometimes these torque specifications can be found in your vehicle's owner's manual, however more often than not you will need to refer to your vehicle's shop manual or obtain them from your vehicle dealer/service provider.

Unless specifically stated otherwise, wheel lug torque specifications are for clean and dry threads (no lubricant) that are free of dirt, grit, etc. Applying oil, grease or anti-seize lubricants to the threads will result in inaccurate torque values that over tighten the wheels.

A thread chaser or tap should be used to remove any burrs or obstructions of the threads allowing the lug hardware to be turned by hand until it meets the wheel's lug seat. Once lugs are snugged down, finish tightening them with an accurate torque wrench. Use the appropriate crisscross sequence (shown below) for the number of wheel lugs on your vehicle until all have reached their proper torque value. Be careful because if you over torque a wheel, you can strip a lug nut or hub, stretch or break a stud or bolt, and cause the wheel, brake rotor and/or brake drum to distort.

Use the dry wheel lug torque values specified in the vehicle's owner's manual, shop manual or obtained from the vehicle dealer/service provider. The chart below lists typical torque values that should only be used temporarily until the vehicle's exact torque values can be confirmed.

Since the thickness of an alloy wheel can differ from Original Equipment wheels, also verify that the lug nuts or bolts will engage the threads. Refer to the chart below to determine the number of turns or the depth of engagement typical for your stud or bolt size.

Hardware Bolt or Stud Size / Typical Torque Range in Ft/Lbs / Minimum Number of Turns of Hardware Engagement

12 x 1.5 mm 70 - 80 6.5
12 x 1.25 mm 70 - 80 8
14 x 1.5 mm 85 - 90 7.5
14 x 1.25 mm 85 - 90 9
7/16 in. 70 - 80 9
1/2 in. 75 - 85 8
9/16 in. 135 - 145 8


When installing new wheels you should re-torque the wheel lugs after driving the first 50 to 100 miles in case the clamping loads have changed following the initial installation. This is necessary due to the possibility of metal compression/elongation or thermal stresses affecting the wheels as they are breaking in, as well as to verify the accuracy of the original installation. When rechecking torque value, wait for the wheels to cool to ambient temperature (never torque a hot wheel). Loosen and retighten to value, in sequence. Simply repeat the same torque procedure listed above.

Thanks for this info. Makes sense.
