I know this is a dumb question but i'm new to wheel spacers. After 100 miles when I retorque do I have to take off the tires/wheels or keep them on and retorque just the lugs from the outside.

 

You need to take the wheels off and retorque the spacers then replace the wheels.

 

What Robar said. The aluminum wheel spacers can crush a bit on install and you're just double checking to make sure this has not happend or if it has, to make up the difference.

 

I retorqued my Spidertrax spacers 5 ft lbs less than the origional torque and only one out of 20 made up a bit more. It may have not been pressed in quite as much at the factory. I check them when I rotate the tires and nothing has budged since then.

 

Same here with spidertrax, haven't moved, I have 14,000 miles on the jk, put them on about 6000, no probs and I check them regularly
