You may want to explain what all over the place means, that's a little vague.
Do you mean it slides easy?
If so, it's the tires, possibly the brand, tread pattern, weather rating.
275's on the front too? That's alot of meat up front.
i got it fixed. way to much toe in. as for 275s up front, eh i was told it was a good size for a 9 inch wheel. no clearance either which surprised me but it is insanely tight.
