Magnesium wheel strength

[03TILLER]

Hey guys, I am wanting to order some new rims but am curious about magnesium standing up for the next 30-40k miles or more. Aluminum just does'nt seem to save as much weight and I'd have to rob a bank to buy carbon fiber. Any info or opinions would be appreciated.

you could rob a bank or buy my Dymag carbon fiber wheels for $2500 with only 1,000 miles on them!

Still trying to convince my old lady $1700 is cheap. I think anything over $2000 would spell divorce!

You can put 30k on magnesium, but they are NOT good at taking shock. On a racetrack = fine. On the street hitting potholes and railroad crossings, I would be looking them over every day/week for cracks.. Just my $.02

I'd be looking the carbon over all the time as well...

Just an F.Y.I.

My co-worker put magnesium MOMO's on his Corvette and they were DESTROYED within 6mo. of highway use in South Florida.

Are the Marchesinis that come on Ducatis magnesium?

[SDTLR]

Yes Miles they are, they better not break

i wouldn't try riding through a rock quarry or goat trails w/ them.

AFAIK, they don't bend, they crack

if you're hitting the track often or ride on relatively smooth roads, i'd go for it. otherwise i'd get something else.

FWIW, i know someone w/ dymag CF's and they've lasted quite a while

Ive hit many HUGE pot holes and never had any problems.

I've been researching aftermarket rims for a while now, and decided against Magnesium rims.

Most Mag rim manefacturers recommend X-raying the rims annually to check for hairline fractures. Like mstingray said, they don't bend, they just crack.

A set of Magnesium rims is intended for track use, and none of the manefactuers I've looked at recommend them for street use. Of course they don't post any warnings or anything like that as it would hurt sales. One company stated that their Mag rims could "easily" go through an entire season without any problems. This statement brings me to the conclusion that these rims were never intended for any type of long term use.

And certainly NOT for the street.

Forged Aluminum is a better option for street use. They are lighter than cast aluminum, and retain the strength of stock rims.
They are still expensive though, and the weight savings aren't anywhere close to Magnesium rims.

Carbon Fiber rims are VERY expensive, but they don't share the risks of Magnesium. Carbon fiber can crack, but it won't shatter like magnesium. Hope this helped.

The roads hear in Louisiana are terrible so I guess magnesium may be pushing my luck. Probably a good chance they would be okay but the slight chance they would'nt is what scares me. Maybe time to start looking at some OZ's.......
