When I bought my xB I installed SS Tein springs and now my tires are getting eatin up both inside and outside. Do you guys suggest I get a camber kit or anything else to help the problem?

 

I would get it aligned first before getting camber kits... it's probably an issue with toe.

 

you busted out the toe. it's not that hard to do but in all of my 50+ scion lowering jobs none have ate tires.

 

Check your tire pressure too.......

 

Tires that wear on both outside shoulders are a sign of under inflation .. not an allignment problem. Allignment would wear only one side of the tire as the tire is being pushed down the road on more towards the left, right, or if both tires are either facing in or out.

 

CBSIMON is correct! Tire wear inside AND outside is an inflation problem.
Although as others mentioned, an alignment is definitely in order after a spring drop, too...
