You can test roundness at tire store on balancer or on car by placing car on stands and rotating tire while marking with a tire crayon or even a nail to scribe lightly. hammer a nail in board with end sticking out and clamp baord agianst a jack stand. Push nail towards surface slowly and should be 100 % contact. Bent axles, out of round wheels etc. will all show up quickly as out of round but must then determine fault. If just out of round and remounting on rim does not fix then a good burn out will. If front wheels they will bolt up to rear for a good burnout to knock of the high spot ! Out of round on sidewall is another story Thank Goodness for warr.
