[Tech] All 4 tires worn out on inside, alignment?

I was looking at 2003 Lexus IS300 today and the car was absolutely great except that all 4 tires were worn out on inside. Fronts were a lot worse than rears (even though car is RWD), pass front tire even had a bubble on the sidewall.
Anyway, my point is. If I buy the car the dealership agreed to change all 4 tires. Obviously I doubt they'll do the alignment. Would I have to do the alignment to make sure this not happens in the future? Car has 54k miles on original tires (Bridgestone Potenzas).
Here's the car BTW.

Could be negative camber and/or toe out. Negative camber means that the inside portion of the tire is taking more weight of the car that the outside portion of the tire. Toe out means the wheels are pointing away from the center drive-line of the car when moving forward.

54K on Original tires is quite remarkable. It sounds like they were quite used up. If the dealer is going to replace the tires then insist that they do a 4-wheel alignment and provide you with the before and after specs. If they don't provide that to you then you just have their word that it was done.

Since the tire wear is obviously uneven, a 4 wheel alignment is certainly called for when replacing the tires.

Check the other suspension parts for wear. It is possible, although not probable, the previous owners used this car constantly for transporting heavier loads and didn't have the allignment adjusted for it. More likely the tire wear is strut/shock/bushing/etc related.

For what it's worth, if a dealer isn't even trying to make a used car look good on the display lot, (ie. new(er) matching tires, washed outside, inside detailed, new fluids, etc.,) I go somewhere else. Trying to sell a car with obvious tire damage is a no-no and a potential liability.

Well in their defense they just got the car recently (carfax confirms - says "15/05/09 Vehicle put on sale").
We'll see on Monday...

If you trust them......

The only good thing about this car, that gives you advantage, is you know something is wrong before signing a bill of sale. Haggle the price with the dealer, then haggle the prices of the various repairs that need to be done before you take ownership.

Check that suspension for wear first. IS 300 is a younger person's car.

I will definitely consider that when negotiationg, thanks.
I don't think I'm really old yet, I'm in my mid 20's
The car is an 'upgrade' from my twin turbo Dodge Stealth. Don't need to go fast in NYC and got tired of dodging potholes. Plus upgraded clutch + traffic = not fun.

4 points:

1. There is a close to 0 percent chance of suspension wear that would result in tire wear. You might have a leaky rear shock, but the parts for that are very cheap on that car (approx $50.00-60.00 IIRC). There is an oddball chance that a front wheel bearing is gone, but that is really rare. An alignment (as maintenance) and proper inflation are musts.

2. There is not a chance in hell that those are the original tires.
They may well be the same brand as OE, but they are not original. Expect 24,000 miles max. on OE equivalent (140 treadwear) tires.

3. Given that you live in NYC, my number one priority would be to make sure that none of the wheels are bent. Those low profile tires don't provide much rim cushion, especially if you hit a pothole with the steering turned.

4. The car *requires* snow tires for driving in snow. This is not an option.

It would be likely that the rear tires were probably on the front at one time, thats why they are worn. My guess would be the Toe is out of adjustment, maybe due to worn tie rods. Only way to know for sure is to have an alignment shop check it out.

Car is from Ohio, there's not even curb rash on the rims.
I took it to speed (90mph) on a test drive, no vibrations, steering wheel was rock solid, absolutely nothing.
Good point about rear tires being on the front at some point.

I just registered on Lexus.com and supplied the VIN number of the car. Lo and behold there's pretty extensive service history for the car. Latest tire-related issue is dated 12/09/2006 at 32544 miles so that makes the tires about 22k miles old which is exactly the lifespan you said to expect from those tires.
