my dad was driving behind me and said my back right tire was wobbling so i guess thats the problem

Well there you go. Now you have to figure out if it's the wheel or the axle.

it was the wheel i took it off today i think the best word to describe it is "lumpy"

Ahah! Slipped Belts! I was right!

Lumpy tire = need new tire. Good call Bleed. Food, take that tire back where you bought it and make sure they replace it - for free.

i just got four new tires today those tires were on the truck when i bought it and i couldn't get a hold of the guy because he's in florida for the winter

So did the new tires fix the problem?

yup drives fine now
