I just mounted a new set of 285/50r20 cooper zeon ltz on 20x12 moto metal 962s. I took them to a shop to have them balanced and they got 3 of them just fine with 5-6 oz but the fourth one they said was off by 370 oz and they couldn't balance it. Is it more likely that I have a bad wheel or a bad tire? They weren't much help in diagnosing the problem, I'm guessing because I didn't buy my wheels or tires there.. Any help would be appreciated.

Ok, it was the first one they tried and they said it looks balanced on the machine but it's throwing up a crazy number. Then they did the other 3 and they balanced fine. But they were still telling me something was wrong with the first one.

i've seen a lot of weight to balance a tire but in 5 years in the tire business i've never even seen anything over 30oz. so 370oz is not possible. you realize thats over 23 POUNDS of wheel weight right?


go somewhere who knows what they are doing. there is no way that wheel was bolted to the balancer correctly. or something else is going on

I took it to Raben tire which is the big chain tire store around here and that's what the guy was telling me. I mounted all four of them myself the exact same way. I've never balanced a tire so I was just going off what the guy said..

Did they retry it a couple times to see if it gets the same thing? If it is different each time most likely something fell inside the tire and is bouncing around during the spin balance. If not have them dismount the tire and remount it 180 on the rim and see what happens.

Well I ended up taking it to another shop and he told me that it will never balance too. I've done some more research on the issue and apparently Moto Metal has had some issues with hubs being off center so I'm thinking that's my problem. I've contacted the dealer I purchased them from so I guess I'll wait and see what they say. Thanks for the help fellas.

Take it to a place that does road force balance. The machine will tell u if it's the wheel or the tire that's messed up

there are ways to center the wheel on the balancer without using the hub. but if the hub is off thats a serious issue. but you can also tell if the hub is off as the wheel will move on the balancer as it spins and can easily be seen by eye.
