Default Rear tires going bad? What caused it? What are some good tires?

Ok so today for some reason I looked under my car and I find my rear tires going bad on the inside wall. Anyone know what could of caused this?
Here are some pics:




Yeah so I need to replace my tires, anyone got any ideas what are some good tires? I don't want to get tires just for racing, I rarely go to the track and I just need something around town and I know that will get me from point A to point B.. I got some numbers from Les Schwab and Firestone.
Firestone:

They told me for 900$ I can get the same exact tires I have right now, I would do that but thats just a bit up there where atm I can't afford it.

Les Schwab:

They had some nice tires, I looked through and liked the ones for 810$ but the All season is what I was intrested in and they told me they were quiet too. I am looking to go with the all season ones for 646$.

How long can I go with my current tires? I know it looks bad and all but I need to go with those for 3 more days and hopefully they won't pop on me.
If anyone has any other suggestions, please feel free to stick em on here.
Thank You

Ugh I feel sick just looking at your price quotes. (I hope my stock tires last!).

Q: It looks like your tires are wearing on the edges (obviously). Whens the last time you had a 4-wheel alignment? I would certainly get one if you are getting new tires.

I'd get an alignment before I got tires. I think it looks like you have too much toe and haven't been rotating your tires.

You know if the front and rear tires aren't the same size (say the rears are worn out) you run the risk of damaging the center diff. It's what's making up for the difference between front and back.

You need to budget for an alignment as well.

That kinda inside edge wear is from excessive toe out. I know. I've seen it MANY MANY times.

It is dangerous to drive on tires like that. I work at a tire shop, and have seen many tires begin to come apart at this point.

You are on the right track with getting 4 tires. Most of the time, you can't get away with just 2 on a scooby.

As far as tire selection goes, check the wheel and tire forum. LOTS of info there.

I have a new set of Pirelli PZero Nero M&S on my 04 WRX. The car came with a cheap set of Falken tires on it and after 2 autocrosses, those looked almost as bad as yours do in the pictures. I love my Pirellis and they should last much longer even with an occasional autocross. They might not be the best, but for the cost and longevity, they seem good to me. FYI, I got them from tirerack.com.

Yeah im doing the Lifetime Allignment deal from Firestone for 169$. Anyone know if that sounds good? They give you allignment when ever you need one and as long as you own the car that car gets free allignments.

That's pretty good. A one time alignment from my shop costs about half of that. Just make sure you ask for before and after alignment specs.

It's a good deal if they will align to your specs - not just get it 'within factory spec'. Otherwise it's a waste of time and money.

Hmmm, that looks more like a camber problem then toe. It doesn't look like the tire is feathering any. You can see there is negative camber in the picts. Common problem when lowering a independent suspension. An alignment might help but if the suspension is lowered too much, you might need camber plates.

Very common misconception.

Plain and simple though, camber alone does not cause wear like that. The toe needs to be imperfect AND there needs to be camber for that sort of wear to happen.

If you have a lot of toe and very little camber, the wear will be more even across the tread and the tires will just wear out quickly instead.

Thanks for the explanation.

Beat me to it. Good explaination, too.

The only time I have seen camber alone wear a tire like that was on a Kia SUV. toe was acceptable (specs called for just a teensy bit of toe out), but it had like 3 degrees of negative camber (specs called for about 3/4 degree positive).

Would it be wrong to rule out wheel bearings completely? When my front went it did that exact thing, but with the miles and the year, im agree camber/toe is more likely

but its easy to check and rule out

yeah, since the wear is on both tires AND because of the mileage/age of the car, safe to assume it's not the bearings.

The stock tires on an STi are very good and are a large part of its impressive performance...something to keep in mind when replacing them with something else.

I'm not saying you have to shell out for another set of RE070s...but at least consider real summer tires instead of all seasons. If you want quiet touring all season performance...the tires are not the problem, you simply bought the wrong car.

I am looking to get the Proxes 4 the All Season tires because I go up to the mountain every once in while and there is snow up there and I think those would be nice because when I went up there with my stock tires I would slip and have no grip at all even with my diff locked. I'm pretty sure the tires can't be that bad and I driven these with really low thread.

Question is, will I slip a lot if I launch or if I WoT in 1st gear or when I shift at redline and WoT will it slip?

I don't launch from more then 4k rpm, and I don't take it to the track rarely.

Will the proxies 4 be good for daily driving and hugging the curvy roads?

I can only agree. I love these tires! Plus, if you're a member of SCCA, there's a $100 rebate on the set right now.

For everyday driving (without snow) you can't beat the Goodyear Eagle F1 GS-D3. The sidewalls are a bit soft for auto-x, but the wet and dry traction is unsurpassed.

The RE050A PP is the appropriate competitor for the GS-D3 - and tirerack testing shows that the bridgestone outperforms the eagle in both wet and dry. the GS-D3 does have impressive ride quality though

I like Falken Azenis RT-615. About $100-110 each in the sizes you're looking for. Last "Grass Roots Motorsports" they won the track/autocross/DD review they did. They've been winning for the past couple years. They have near R-comp dry performance and aren't bad wet. The tread pattern looks good too. I wish Tire Rack sold them. I like Tire Racks service.

Your tire guy doesn't know what he is talking about...Your car needs an alignment...the toe is probably out of whack.
