Need lug bolt information

I am getting rid of my knockoff wire rims as they are just too hard to seal and go tubeless. Many attempts and just as many failures. However, fortune smiled upon me recently and I found a gentleman who had a brand new pair of Dayton wire wheels he purchased many years ago but never used. (long story) Short version- I was able to purchase all four of them for $300.

As I was taking off the old wheels I also had to take off the knockoff hub adapter which was secured by 5 lug bolts. Fine. It's then that I realize that there are studs to attach the new 5 lug wheels to. In other words, there are five threaded holes in the hub for mounting and not the five studs that I was used to in my youth. Yes, this showcases my inexperience with wheels since I've always had the knockoffs.

My question is: Does a 280SL use mounting bolts and if so what size dimensions/thread count? The 5 I removed from the knockoff hub adapter are too short and not chrome.

Thanks for any advice~

yeah they are lug bolts, no studs. there are two different length bolts available. Sounds like you need the long ones. Mercedes has been using the same setup for eons. I would just go to the dealer and pick up some new chrome ones as the quality is better than the aftermarket. Genuine parts are not as expensive as
everyone thinks.

you have to be carefull there , if you put too long of bolts at rear , it will catch the hand brake shoes and do bad ., so make sure the wheels turn by hand first before driving .

- Thread pitch: (to match hubs)

- seat type: (to match wheels, ball or tapered/cone, but later wheels that use 14x1.5 lugs instead of 12x1.5 have bigger balls, so this is a catch that you shouldn't have to worry about since I doubt your wire wheels are for newer cars)

- length: I think that most Benz cars expect the lugs to stick out the back of the wheel by about 3/4" / ~17mm. You should measure how far your stock lug bolts stick out the back of your stock rims. Then try the same lug bolts in the "new" wheels and see how different the bolts need to be with respect to length.
