hey guys i put on some 19 inch rims on my tls and i need to chnage them back to stock.

the thing is i forgot to mark which tire was where on the car.

so i am basically putting whatever tire on whatever location. is it ok, to just mount them on without re-balancing them?

the stockers have been off for about 3 months.

 

Always good to have rebalanced. If you still have the stock MX's still on the factory wheels they are not directionals so it doesn't matter where they go back on the car.

 

Rebalance only needed if you see uneven wear or your ride is not smooth. When most places rotate tires they do not rebalance them.

 

thanks.

 

yeah, dont rebalance them unless you get vibrations from steering wheel.
however, remember that its not just uneven wear that requires balancing. Each tire is unique, and i dont mean brand wise but rather one tire vs. the next. That is why tires need balancing, because they are no two are exactly the same.
