This is very very weird.

Just had 2 of te sae fitted on the rear of mine cost -

Yes - but Shepp's is a MY 2002 ... so has 225s on rear

I put 4 RE050's on mine before doing a few thousand miles in France. I like them; good grip and the side walls seemed pretty stiff. IIRC they are both directional and asymmetrical.

I have 225's on the rears - but when I came across an older Boxster (not s) that was running 265s I think (might have been 255) on the rears I was surprised that a very similar car had so much more rubber?!

Where's its lump though?

Also, German cars are over-runnered usually, which is why they're all roadholding & no handling.

The 16" S-02s have a 245 tread on a 225 carcass, as most forget!

Actually, I've jsut checked that:

The S-02 ES02JZ's tread is slightly wider than S02J's by about 1/2 cm on worn tyres.

It's nowhere near 245!

That's another S2000 urban myth destroyed.

I reckoned measuring them the fronts (205) were 195, and the rears (225) were 240. I compared that to the 195 Bridgestone tyres on my Primera which really were 195, so I think I was measuring correctly.

I've still got an old S02JZ in my garage, and I measured that to be only slightly smaller than the ES02JZ. So I think they pulled the same trick with the Porsche one, just not as much.

So changing to a genuine 205/225 is going to give you more front end grip and less rear. I now have 205/245, which I feared might make it more understeery but has done the opposite.

H!cks

Interestingly enough, since I replaced the rears on mine a month ago with RE050As (still have S02s on the front) the car has been ever so twitchy. I was starting to think that maybe the GEO needed doing so its interesting that someone else is having a similar thing.

I was going to put an ask out on the next meet in the area, to drive it and see what they thought....

This is a proper tread pattern:

It's the amount of rubber on te road that makes the difference. The rear S02s have narrow rain channel which give it the same rubber on the road as 245 - in my understanding!

Ive still got So2 on the front. I have noticed that on sharp corners (mini roundabouts) the rear is pushing the front out so the S02's squeel a bit when they didnt previously. The S feels ok on the road and corners well, but it almost feels like the 4 wheel steer kicks in every so often, hence i could do with a geo check.
the floatyness of the car is gradually reducing with more wear on the tyres as they soften.
I could really do with a geo check, is Chris coming up North
or any other suggestions..

sorry when i mean non directional, i was refering to the tread pattern in comparison to the S02's
