Heya,
Just a note to let you know of a particular brand of after-market rim.
I am fortunate to have a second set of alloy "Performance" brand Aussie made 8 spoke rims for my 2010 D4. I use these rims for off-road use as they give me a better range of tyre size and I've got Cooper Discoverer LT 245/70 R17's on them and am happy enough with the off-road capability.
Main point is that after a weekend of fairly mild 4WDing, I was giving the D4 a clean and noticed a cracked spoke on a front rim.
Got the tyre removed and was very surprised to see the crack was completely 360 degrees through the spoke (It was an easy drive over the weekend).
1st option was to ring the manufacturer and price up a new rim rather than have it welded but my second surprise. After decades in business supplying performance rims to all makes and models - Performance rims have gone out of business and have shut their doors. Bloody shame to see another Aussie business go under!
I have since had the rim welded up without any drama. Seems that once it cracked, it stress relieved so should be good for future use as a spare.
Was a problem with some of them - you're not alone with having had some crack.

Check the other rims - from the inside.

SubscriberHey Cattmatt,
Look alot like this mate? There's been alot of people who have cracked every version of the BB6 wheels. Personally I've cracked 5, four of the previous version and one of the latest/last version. If you ever require a new one perhaps give TerryO a call, I have a suscipion he may be have an extra one or two laying around LOL.
I am interested in how you had it welded up?? The wheels are a forged cast correct?? Was it TIG? MIG ?? Other??? I've always thought welding cast to be difficult at the best of times....
regardless I hope it works for you.

It was a difficult weld and we had to heat the wheel to over 150C. Even then we were left with some small pitting and 'blow-holes' using a TIG but overall I'm pleased with the results and strength of the weld. (And yes, I do believe they are forge cast)
I've since spent a lot of time polishing the weld smooth and have painted it with base and top-coat. It looks like new!
My welder mate only charged me $180 plus a 6 pack of Coronas so we are both happy with the final result.
Cheers mate!

SubscriberI think you'll find Performance wheels are all cast, not forged. Forging is a different process and uses a different alloy which results in a stronger and more ductile wheel. Increased ductility is good as it reduces the chances of brittle fractures like the ones you are experiencing. They are also more expensive.
Cheers,
Jon

Compomotive wheels are cast, then heat treated.

Have you considered having the repair X-rayed?

Could these these cracks be coursed from a bad cast , they are rated at about 1400kg strength . I have had my new type 17 inch rims that take the OER wheel nuts and tensioned to RRS specs since 2013 and have not had a problem YET !! , do not do any real rough off road rock climbing stuff , just normal on & off road driving
The fact that they all seem to crack on a spoke near the centre maybe a sign of a bad design or just cant handle any rough stuff .
Anyone have any theories .

SubscriberThanks Tombie, I stand corrected. Always thought they were forged. Edited post to reflect reality.
Cheers,
Jon
