Hi, Im just wondering how long is the original wheel studs when installed. I've ordered a 25MM bolt on spacer, and my wheel doesn't have the holes in the back for extra studs to go through.

 

What year model LS you own? There may be some year to year differences.

 

Its a 1998 UCF20

 

25mm will sit flush with the studs. So if you bought just a spacer, not an adapter, you'll have to buy extended studs to be able to mount the wheel.

 

the OP said they are bolt on, so they are adapters.

25mm is going to be very close to clearing. you might have to sand down the studs a bit.

 

For those who search this later on the solution is extended Tundra studs. You can get them from Japan or as of this post there's a user named usedwheel on eBay that also sells them.
