As per title. I noticed recently that the turn in on my S seems a little less accurate. It seems to be more understeery (if such a word exists) I had the alignment done a month or so ago. I wondered if my tyre pressures could be wrong (34psi) and if that would make a difference.

 

Turn your steering on to full lock and inspect the inside edges of your tyres. My guess is they are worn

 

Wear on the front inside edges is very well hidden and make a huge impact.

 

there is a small amount of wear on the outside edge but the tyres are not at the point where they are really bad (only been on car for about 2 months)

 

Im wondering if I have the tyres underinflated as the wear is on the edges and not the centre.


perhaps 36psi would cure it to an extent.

 

If the pressures and geometry are correct then the front tyres will wear the inside edges first. I pushed my S2000 pretty hard on turn in and corners and as a result I had near bald inside edges yet the centre and outside (visible parts) looks perfectly good!

 

i always was under the impression 32psi was the reccomended pressure. i could be wrong!

 

That's not pushing the front hard enough!

The tyre should roll onto the outer edge whilst cornering. the inner wheel is unloaded.

Inner edge wear may be too many straights & not enough bends.

Dan,

If your car feels more understeery since the geo, what have they done to it? Too much toe-in either end, too much Front castor, way too much camber even?Settings please, Carol.

The weather's been colder last couple of weeks: your post is unclear as to whether the understeer problem actually occurred since then or the spannering.

 

i.e. road driving

 

...like yer grandad

Oh, I've turned into Inpector Dreyfus.

Clouseau!
