How Strong are Welded Rims?
This past winter I hit a rock or re-bar or something nasty on the road. Sharp enough that it destroyed my tire and left a huge crack in the barrel of the rim! Not just a hairline crack, but a big dent type of crack where the metal was bent, resulting in a big, gaping hole.
The rim was a SSR GT7, now discontinued. I think it's described as a semi-forged wheel? In any event, I had it rewelded and there don't appear to be any vibrations. What I want to do is to convert these winter rims into track rims. They are +38 or something like that, so I'd want to put 245/40/17 on them for a square setup. The acid test question though: is the rim going to be strong enough for track duty? |

very unlikely they will split, but they are damaged, and there is a risk
Not worth it in the end get a set of orig BMW wheels used for trackbashing, or get ready for a huge repair cost if you loose it on the carousel...

i know geez , im not either
Welding is a super tough joining ! f**k man, they build tanks that way But its more cause his wheels have had a buckel, ant the metal is already stressed and weakened.. it might cause a faliure But no digs at u bro

I feel that the weld is not the big issue here.
most 2pc wheels have welds and/or bolts that join the face to the barrels. this is not at all weak or the wrong way to build wheels. it has been like this for a long time. they build most steel wheels, this way and a lot of wheel companies use this technique as it is strong enough and allows them to customize the offset and look, including SSR, Work, and many others. I think that the problem is the crack/fracture. with enough stress and heat, the metal may cause to fatigue and fracture or easily go out of shape.
