My 06 has 15K miles of rather enthusiastic driving, and I was surprised to notice that the front tires are worn more on the inside than the outside. The wear pattern looks pretty even, no sawthoothing that would indicate toe-in off. I've been running 40psi all around. These are the oem Bridgestone Potenza RE-050's on stock wheels - 17x7 front, 17x8.5 rear. The rears are wearing as well but more evenly across the treads.

Is this just normal consequence of factory alignment optimized for handling over tire wear? I have not adjusted alignment at all; never hit any big potholes or curbs, but I do corner fast sometimes.

 

your tire pressure first off is way too high, 32psi is optimal. second have you alignment checked to verify that it is not out of specs.

You will however notice more wear on the insides edges of the tires on the front and rear due to the stock alignment specs, just part of owning a car like this.

 

First off, you need to be running the factory air pressure specs. Look on your driver's door jamb, you will see that the recommended pressure is 32psi. This can have an effect on tire wear.

Secondly, if you have been driving rather hard, you may have noticed that with the stock alignment the car tends to understeer slightly. I have noticed increased wear on the inside of my fronts as well, and I think it might be a product of the understeer combined with the amount of caster the S2000 runs causing the inside of the tires to wear.

Anyone else has any ideas please drop in!

negative camber and toe would have an adverse effect on the inner tire wear

 

a wrong toe angle, wether in or out usually creates the cuppin' or featherin' on the tires. since he said that it was an even wear i'm leaning more towards camber. but again it all needs to be checked at a proper shop with a good alignment machine, preferably a Hunter with the WinAlign

 

If you change caster you change toe. In the front, the wear on the inside is more than likely caused by toe especially since he has been doing spirited driving.

With spirited driving, additional neg. camber alone would cause the tires to wear MORE evenly as the cornering force is spread through the whole tread.

Your car is probably toed out in the front. It happens over time. Get tires first. Get alignment second.

40psi is a little high, but would prevent the inner edge wear a little bit in most cases. Since high pressure puts more wear on the CENTER of the tire, it keeps the edges off the road a little.

I use around 38-40psi to start with when road racing. It keeps the tires cool and it offers a little more grip for my setup.

32psi is not "optimal" for handling. It's "optimal" over all. Honda has to think about ride quality, tire wear, etc. If you're thinking about JUST handling or trying to make your tires last longer under special conditions, 32 is not always optimal.

 

>>higher tire pressure will give you wearing on the center of the tire, while low pressure will result in wear on the edges(sidewall corner<<

Exactly. And my fronts show more wear on the inner edges in spite of running 40psi. B Serious I agree with your comments on tire pressure. I've been running 37-40psi in all our cars for years, and doing my own alignments; gotten good performance and tire wear with this regimen.

It's definitely not toe - doesn't show that characteristic sawtooth wear pattern. Believe me, I've seen it before.

I think it's just a case of a car set up for handling over tire wear - I can live with that.

I'll check my alignment as soon as a get some free time.

Hey ronnuke, could U comment on those upsized 225/17-45 & 255/17-40 tires? I'd expect a small but noticeable loss in acceleration, but prob more than offset by that light flywheel. And what is your flywheel?

BTW light flywheel is #1 on my future mod list, as I've had great results from them on other cars. Well actually #1 is prob wheels / tires, if I decide I can afford a nice set of 18's. Not gonna open it up for flywheel until 1st clutch is worn.

 

I noticed my front tires are wearing out on the inside as well.
It's an '07 w/ 11k miles on it, with 2 visits to the Dragons recently.
Funny thing is though, the rear seems perfectly fine while the fronts are wearing out early.
I guess I'll have to check my alignments soon.
