2015 Tacoma
​​​​​​I got new rims need 4 5/8s back spacing rims are 5" so I was gonna do a 1/4 inch spacer the new rims are thicker then stock e/t lugs still don't catch enough threads can you replace studs with longer ones if so where can I get them

 

Why didn't you buy rims with the correct back spacing?

Dorman would have the correct wheel studs, any quality auto parts place could find them

 

2006 toyota matrix studs will work. They are 55mm long and have a blank unthreaded section a 1/4 inch spacer or thicker alloy wheel will cover and still have plenty of thread for the lugs

 

Head to a good NAPA or Bumper to Bumper. They will have a Dorman catalog that will have the studs you need. I say Crows or NAPA because they will usually have someone there who won't scratch your head when you say you need to get out the Dorman catalog. Most of the Advance or Autozone folks around here won't know what you're talking about.
