Anyone ever had this happen? 2008 Ram 1500, QC, 4wd, 20" factory rims with the chrome insert. This has happened twice in 6 months.

 

Wow. Never seen that happen before. Corrosion? Are the tires the proper size for the rims...width wise?

 

Was it the same pothole?

 

Proper sized tires. Factory rims. 2nd time in 6 months, just pulled off the highway and it exploded. No potholes were involved in this incident.

 

Now that is just bizarre..... Tires inflated to proper pressure? Though, if they were over-inflated, I would expect the TIRE to fail, before the rim did.......

This is the first time I have seen/heard anything about this, so, apparently, it isn't a 'common' problem, else the forums would have oodles of threads about it..... Does the break show any evidence of a pre-existing crack? Can you get a close-up of the area on the wheel where it broke off from??

 

I run 36 psi. I am going to my local Dodge dealer on Friday. I run Cooper AT3 4S tires and love them! I am also going to shoot an e-mail to Cooper.

 

I don't really see any evidence of a pre-existing crack there...... did the damage to the trim ring happen when it blew?

 

Yes. The broken piece flew about 15 feet.

 

From pictures it's difficult to determine for sure. IMO, The dark and lighter areas of the part that flew off sure indicate a pre-existing condition to me. The 4th picture in post #6, on the right side, the edge of the break above the lighter area is dark. This can indicate some age to a defect. The left side which is darker than the right also appears to indicate some age.
Also, picture 2 of the same post appears to have an open surface crack or void on the right, just above the ring. Possibly from hitting the pavement? Then too, it could be a pattern of rubber transfer from the tire.
Generally a surface crack in material doesn't reflect light to well where as a scratch or nick will tend to.
