Flat spotted the tires??

[gitchesum]

Last night coming home I had a guy swerve in front of my truck while I was running about 75. Had to slam the brakes and skidded about 75 ft. After that, the truck had a bad vibration from the rear. I checked thing out underneath but couldn't see anything. Checked the u-joints, carrier bearing, transmission mounts. The only other thing I could think of is that the rear tires are flat-spotted.



Anything else I'm missing?

Do a few burnouts. Maybe that will round them out again

That's what I told my wife I was gonna have to do. Maybe I can do it when I finally get to run it at the track.

Took my truck to the dealer the other day and the rear antilock brakes weren't working. After replacing the RWAL sensor in the rear end and the CAB unit and the valve assembly in the front end I thought they were done. As I was driving in the days following I noticed a vibration at my feet in the floorboard. After looking at the driveline, I decided to have my tires balanced and come to find out both front tires were flat spotted by the technician that slammed on the brakes while trying to test the antilock brakes. The dealer replaced the tires. Vibration gone.

Do a burnout. Preferably in a busy intersection with a big audience.

A burn out would be fun, but

A trick from the big truck boys is to rotate the outside dual on each side 180 degs. I'm thinking you've got a dually, if not, I guess a burnout is the only option.

You might check with your insurance company, you did this while avoiding an accident. That is if your deductable is not that high. Worth a phone call

Now I'm confused.



Half of the guys are trying to talk some sence into me.



The other half think I should try and save the tires I got.



Might have to check the tire budget.

Gitz - Find where that guy lives and do your burnout in his driveway.

Do the burnout, BUT... do it in front of the FORD or CHEVY dealership. If anyone asks, just tell em a Dodge tech told you to rotate the tires to fix a vibration.

I cant believe this.



You have the grill guard, so why are you wearing out the tires for some idiot?? Push him into the next town, and repair your front end with a can of spray paint. Its cheaper... .

John,

You have no iidea how many times that has crossed my mind.

Unfortunately, I was going about 50 mph faster than him and would have probably taken the entire left side of the truck off(it was a Ford after all).





Make you wonder what people are thinking when they pull out in front of a truck with a 400 lb. bumper hangin off the front of it.

the flats

My rig had 6k on it when my wife flat spotted the fronts. Some dolt pulled out in front of her while she was doing 65. The thirty feet of black marks used up about 1/2" of my factory Michelins. I just had to replace them because I did not want the vibration to damage any other expensive Dodge parts like hubs or wheel bearings.

There is a slim chance you spun the tires on the rims. Or lost a wheel weight.



A bit of a flat spot shouldn't cause *that* much vibration. Besides, the RWAL should've prevented the rears from locking up too hard.

Rotate the tires. Ha... LOL Oo.

Curtis,



Although the damage might be too severe to correct, you might check a good tire shop and see if they can true up the flat-spotted tires. If they're really bad, they'll have to remove about a jillion miles of tread to do it, though.

A burn out may work but might get you a ticket.



Take the truck to a good tire shop and have them trued and matched. Trueing will grind them so that they will roll round and matching will make them all the same size. This is important for a dually to properly share the load across both tires on the each side.



I have also done this on brand new tire and gotten an additional 15K to 20K miles them. It sounds counter intutive that removing some thread will make them last longer but it does. They roll so much smoother after having it done. I think the last time that I had this done it cost me ~$20/tire. It was a little cheaper when I bought a set and had them done at the same time.
