Are my wheels warped?

[broken scope]

Finally got my shimmy fixed by balancing tires. So l rotaded them myself without balancing them again and the shimmy has returned. So at least now l know for sure its in the tires or rims. I took the spare to get it balanced and same place thet balanced other 4 tires said rim was warped. So today l placed a piece of rod at the outside edge of the front rims and theres probably a 3/16 high spot on both front rims. This is the second set of new tires l have had trouble getting balanced on these rims. Do you think my rims are warped? There Blackrocks and have never been off road.

Man I’m not sure , but I’d have em broke down and checked

It's possible your wheel(s) are warped beyond balancing. I'd have the tires taken off them and have the wheels inspected by a reputable shop. They should be able to tell you pretty easily.

Ive had two different installers tell me the rims were warped but l didnt think they were since they were practically new. I watched a youtube on how to tell if rims were warped lol. I just dont know whats considered acceptable but l dont see how they couldnt wobble with that much difference. Im going to mark the high spot and loosen lugnuts and torque at different nuts to see if the high spot moves.

There is a big difference between running true and balancing. One of the most out of true running things in the world is a crankshaft and they balance them to run perfectly without vibration. You can also balance and out of true rim to run without vibration on the machine. It isn't until you put it on the ground that the out of true overcomes the balancing. It is still balanced, it just isn't capable of running without vibes.

Why is that that once you put the out-of-true (but balanced) wheel on the ground that it isn't capable of running without vibrations?

I could easily stick a wood ruler in the gap difference it creates when l spin the rim. The first set of tires were road force balanced on new tires and they didnt mention a rim problem. Tires still shimmied.

Because it is bouncing off the ground or trying to no matter how well it is balanced or wobbling side to side.

You are going to have to isolate the issue to the rims. Do you have a rim that runs true? If so, put it on the corner that runs the truest and check the rim run-out there. If you can't, then it may not be the rim. It may be a bent axle or dying unit bearing.

I will do that l really think the rims have been my main problem. I will report back thanks

I checked all my rims and the back ones werent as bad as the front. Blackrock discontinued the fake bead locks like l have so l might just get two crager soft eights to put on the front just to try it. After l wear out these new tires im going to 15in rims.

Take your wheels and tires to a tire shop that can actually measure the run out on the wheel and show you!
Don’t listen to a members theories, go to a professional.
We have a road force machine to measure wheel runout as well as tire run out. We show our customers the problem while it’s on the machine. Find a good shop who cares.

You can have the wheels fixed locally im sure, if you do some talking with the local tire shops.
