Hey guys,
Here's the scoop.
I've got 20x10's with 275/30/20's on the rear of my 8.
Don't criticize them, they were on it when I got it.
Anyway, the rear tires have maybe 8,000 miles on them.
I had them aligned around 4,000 miles.
The insides of the rear are so bad that they need to be replaced alerady.
I had noticed them wearing on the inside quicker than the outside, and that's why I got an alignment thinking it's a camber issue.
The guy at the alignment shop set the rear's to -1.5 and told me that would be sufficient and that he couldn't adjust them anymore anyway.
The rear toe is 0.05 on both sides. Can't remember if it was negative or positive without looking at the sheet.
Anyway, they're shot. Found this photo on the internet, and they look almost this bad.

I'm going to buy two new tires, but what can I do to prevent from having to buy 2 more in another 8,000 miles?
I appreciate the help, you guys are wonderful, Thanks.

I run 275s with factory camber in the rear. I don't know what "factory camber" is persay but I've never had an alignment done on the car and the rear tires have a little camber to them however they came from the factory. My wear patterns also indicate camber. However, the tire wears across the whole surface and just a bit more on the inside. I ran a set of tires to the cords and they corded on the inside edge. However, the tires were bald all the way across. If you are running X amount of camber, the tire should wear in at X amount of degrees. The tire you linked is worn on the inside corner only so it was running at an extreme amount of camber without using the rest of the tire. I guess you could draw across the face of the tire with some chalk, take it for a little spin and see how much of the chalk remains. If the rear wheels are set out too far, then you need to run a lot of camber to have the tires clear the fender. And if you are running a lot of camber, then you are going to destroy tires. Really, all you can do is run as little camber as possible and still clear the tire on suspension travel.

What brand/model of tire is it? Any idea the offset of the wheels? Can you post a couple pictures showing the amount of camber you have?

Sheehan... its normal, Mine also wear out faster inside that the out.. I am also running 20's and I would say I am at more than 1.5 neg camber.....(in the rear) I find myself replacing my rear tires every 10-12k mi, depending on how i drive. I have been running on Nitto Neo-Gens and have been running for about 3 years now and have been through 6 tires, 3 sets of pairs... at about $140 a tire....IMHO.. its just the way it is .... My tire size is 235/35/ZR20...Nitto Neo-Gens...... good luck and once again... its normal..

If our lug pattern is 114.3 ? They offer this wheel in a 20x10 with either a 25 offset or a 40. I'm not sure which one it is. Would it say on the inside of the wheel? The tires are Nankang NSI or NSII's can't remember without looking obviously not the best tire money can buy but surely they're better than 8,000 miles haha. I can get pictures of the camber tonight, and also pictures of MY actual tire wear.

Nankang= a big part of the answer for FASSSSTTTT wear (used to have them on my ACURA) and boy...I would get them for cheap but they would get bumps/lumps very easy, wear out easy, weak sidewall, and start to sag and just suuuuckkkkeeedddd. Tires are more important than wheels....always..its what keeps you on the road. But with 8000 mi on Nakangs... I say you are getting a good deal..if it were on brand name...then yeah.. you would be getting ripped off....IMHO get the same tires I have and you'll have a better experience..

Sheehan

Would Yokohoma S.Drives be any better than the Nankangs ? I can get them about the same price. The 275/30/20 isn't a real popular tire size haha.

Change the toe to zero

toe angle + camber is what scrubs off the inside tread, if you go to zero toe the wear will still occur but at a much slower rate, this is an old alignment trick that track people use if the car needs to operate on the street too

Sheehan

I've spent most of the morning searching and I found several other references to this. I think I will take your advice and get them to throw my car back on the alignment rack and set my toe to 0 when I have them mount my new tires. Thanks !

sorry bro, never used S drives

maybe ditch the 20s? 18s would give you better prices at least and more choices
