when to put my winter tires on, and I found the passenger side summer tire to be extremly worn from the inside??? all other tires are fine, what gives?

Might be a camber issue?

alignment

aligment seems fine - car drives straight as an arrow

Holy god thats bad.

Wow, that looks like an alignment issue.......I don't know what else would cause that??? Man you must have had some fun rides in wet weather with those tires!!!

sadda///M · 11-14-2003, 08:43 PM

how can you say it drives straight as an arrow with that tire on?

worn suspension/shocks? maybe but not likely

alignment geometry is focked up.. negative camber or toe-out. have it align.

Assuming the worn out side was the inside part of the rim, you’ve probably got a negative caster. Is your car lowered??? Lowering a car more than 1 inch usually introduces negative camber; this can vary though depending on the car.

It also could be a Toe in on that wheel.

Go for an alignment and have it checked out.

I’ve had negative camber on both front wheels and the car always drove straight. I’m not sure what would happen if it weren’t just one side; it might pull.

From the Net, here is some info about Camber, Caster, Toe

Camber
Camber is the tilt of the wheel in or out. Positive camber readings show the top of the wheel is tilted out, while negative readings show the top of the wheel is tilted in. Theoretically, you want the wheel to be at 0 degrees or straight up and down, and most vehicles are close to this, but suspension design or handling demands may require negative caster settings (Negative camber is usually used on performance cars).

Caster
Caster has no effect on tire wear. Caster is used for vehicle stability. Too much caster and the wheels can begin to shimmy like the front wheels on a grocery cart when you go too fast. To little caster and the wheels don't follow the path well. Caster is essentially how far forward or backwards the wheel is in the wheel well.

Toe
Toe refers to the in or out turn of the wheels from a straight-ahead position. Incorrect toe settings caused by wear or impacts can wear tires quickly. In the past, most vehicles would have "toe in"; the front of the wheels were turned slightly inwards. This gave good vehicle stability, and as vehicle speed increased, the tire resistance would cause the toe to change to the straight-ahead position

Rear Passenger wheel? As in the drive wheel?

That's what my buddy's Mustang's rear passenger wheel looks like.
