Just having done Academy Day on Saturday (well Becky did, but I felt I went through it too!), I did the usual checks last night.
To my amazement it appears that not a drop of oil was used. I must admit, with pretty much constant V-Teching I was expecting it to have dropped a couple of notches.

But to the point - I am starting to notice some uneven wear on all the tyres. The edges (inside and out) are about 2 mm down on the centre, not a massive amount I know, but I wouldn't want it to get worse.
They have always been run at 32 psi, the car having covered just 3200 miles from new, except for Academy Day when I put them up to 34 all round.
I am not suggesting that one day would have caused this, it is just the first time I have checked how they are wearing.

This is our first real sports car, but with previous saloons I have always run the tyres at about 3 or 4 psi higher than the manufacturer's recommendation. It was something a friendly mechanic told me to do years ago and I have always followed it. He showed me several cars where the edges had scrubbed more, and I must admit that I have always had completely even tyre wear by adding a bit more pressure than recommended. I have even run my Civic at stock pressure as an experiment and have noticed in the last 10k miles that the wear has become greater at the edges.

BUT, we are obviously not talking a Civic here, so...... in theory do you think I would be compromising road-holding by getting a bigger footprint on the road and running at, say 35 all round, and does anyone else use more than 32 all the time?

 

I've ran at 32 psi since I've had this. My tyres are worn more on the outside too - maybe one or two mm to the wear indicator on the outside grooves, four mm or so on the central grooves.

 

Yep when mine were replaced the wear was not even at all. I guess this has something to do with the wheel alignment ?

Didn't use any oil either this weekend

 

Thanks guys and hope you're both doing ok
It's not just mine then, probably nothing to worry about

Would still be interested to hear from anyone who regularly runs higher pressures, and whether they experience the same wear.
I guess now I've got another chance by getting this thread back onto page 1 before it dies a sad and premature death

 

I run mine at 34psi have done since i got Eagle F1's and read something here, i actually prefer them at 34, but is that cos it is what i am used to? i dunno. but i can tell when they are down at 32, the car feels different.

I guess if the wear is the same on either side of the tyre, that has to be pressure, rather than alignment. It is normal on the S though to encounter wear on the inner edge of each tyre, it is a characteristic - especially with a lot of motorway miles AFAIK

 

Track testing proved early on that unusually, keeping the pressures at recommended produced the fastest times.

I have always got very even tyre wear, which suggests the recommended original alignment works best for fast road.

Some track boys like to run a little more camber though.

Don't do that if you regularly bash motorways, though!

(Cue Mike's tyre anecdote

 

I run the OEM SO2's at 32psi and my Toyo T1-R's at 34psi, due to them having a softer sidewall than the Bridgestones.

When I first fitted the T1-R's I ran them at 32 all round, but felt the car moving around on the rears when pushing on, a couple of PSi later and it's handling great.
As for tyre wear, well it's a bit early to tell on the Toyo's as they've only been on a week, but the SO2's are slightly worn on the inside edges only

 

I'm not sure I'm brave enough to start messing around with the alignment just yet

But I think I'm definitely going to run around at 34 psi for a while, keeping an eye on the wear, and see if I notice any change in the next couple of thousand miles. As AE suggests, it is probably more to do with pressures as both tyre edges are affected.
As I mentioned, they were on 34 at Academy Day, and the grip was certainly unaffected, Becky describing it as 'pretty awesome'. Not sure if that means any better or worse however.

 

when on track, i have tended to always up the pressure by a couple of psi...
