How Strong are Welded Rims?

who's ur daddy? · 06-15-2009, 01:16 PM

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?

No F'ng way would I run at the track/ any where with a welded rim

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...

iforgery are welded to 'stamped' barrels. what do u think of that?

MalM3 · 06-15-2009, 02:10 PM

i have no problem with welding .

I have a problem with the metal has fatige , and can fracture under heat and duress..

what do U think of that?

i have no idea! im jsut saying that every1 praises iforged wheels when in fact theyre not even forged and theyre welded also ie not true multi piece wheels. not having a dig at u

MalM3 · 06-15-2009, 02:24 PM

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.
