I found this in another thread posted by dlq04:

My tires front and rear seem to be wearing on the insides. I always keep my pressure at 32 lbs and check them often. My car rides straight as an arrow. I have 12k on my car now. When I replaced the rears at 7k I had an alignment done and nothing needed to be tweaked/adjusted.

My QUESTION is, regarding the quote above, is this true? WIth stock alignment specs, they will wear naturally on the insides? I'm can be an aggresive driver at times, but never peel out - maybe the occasional slide around a corner....

Thoughts???

 

Camber is the angle of the wheel, measured in degrees, when viewed from the front of the vehicle. You have positive camber if the top of the wheel is leaning out, away from the car and negative camber when the top of the wheel is leaning in. Too much negative camber will wear out the inside thread of the tire and too much positive camber will wear out the outside of the thread. If the camber is uneven, the car will pull to one side or the other. It will pull to the side that has the most positive camber.

Factory Specs from Honda Workshop Manual; camber is the first number and as you can see both front and rear are negative numbers.

F - 0

 

My car was out of alignment when I replaced my S02s at 7K miles last year. Have a four-wheel alignment done when you do your next set, Jason. I contend that my car came from the factory out of alignment.

 

What's the max psi on your tires 44psi? Raise it up a little bit like up to 38 and that will decrease your rolling resistance giving you less wear and better mileage especially if you are not too aggressive of a driver.

 

Wear on the insides, especially in the rear tires is normal for this car and any that comes set up for the type of driving that this car was designed for. That's I did this:

ps. 32 psi is the "recommended" pressure for our tires. I run 35 - 36 psi. 40 might be a tad on the high side for ideal performance (grip).

 

The trick is to take the car out on the track to wear down the outsides so they match the insides

Otherwise, yes, with the way the camber is specified it is normal to wear the insides earlier.

 

When I first found this site three years ago, a number of people were recommending very high pressures. As a result I tried numerous seat of the pants tire pressures tests driving around the countryside. Each day I would change the pressures, raise the front, raise the back, make them the same, you name it, I tried it and recorded my results each time. In the end I settled on 34 front and 34 back. Naturally these are cold settings, as once the tire warms up it will rise another 5 to 6 pounds. 40 may be fine for a "hot" pressure reading but certainly is too high IMO for cold.

As a result, when I tracked my car the last time I set my tires to "my" normal cold read of 34/34. After several hot laps I pulled into the first stall in the hot pits and my friend took three temperature readings on all four tires. The goal is to have even tire temperatures. The person assisting me crews for an IRL team, a Bonneville team, and a vintage racer team. So he knows what he's doing and had good equipment. Even he was impressed. I was getting perfect contact on three of four tires and the last tire we only raised the pressure by 1/2 pound. Everyone has their own driving style, so that can be a factor as well.

I'm sure your alignment is fine. The negative camber will wear out the inside of the tires first, it's normal.

Just to give some basic background, since we drive a sports car, we have more negative camber than typical passenger cars. The negative camber provides more lateral grip for faster turns. Imagine the car leaning into a curve. The weight shift causes the tire to distort, but because of the negative camber the tire's contact patch becomes even across the tire making better grip. The more hard cornering the more even the wear or outside wear on the tires.

So do what Ludedude says, more roadtrack corners and less highway

 

You can always have your tires "flipped" so that the outside with tread is on the inside. That should help you get a few extra miles. I still have my original front tires (on my '00) and they have about 27k miles on them. I had them flipped at 20k miles because there was still plenty of outer tread left , although doing it at 15k miles would have been better but I wan't paying enough attention. It cost me less than $20 to have them flipped, rebalanced and put back on at Discount Tire. I'll have to get new one's at about 30k miles, but the $20 was well worth another 10k miles.
