I'm thinking of going with Toyo R1R's. Anyone here have these? I wonder if they will help in the same way your new tyres helped Fat Albert? (Although I realise changing the tyre size may have a bigger impact.)ORIGINAL: Fat Albert
My '88 220 Turbo runs 205 front and 255 rears, my understeer has been drastically reduced by switching from P6000s to Falken 452s on the front! I am on my second set of 452s on the rear, the first lasted 28,000 miles!

Again, pardon my ignorance but would fitting 235 front and keeping 255 on the rear reduce the impact of under steer?
This is assuming its possible to do so?
The problem is the rear - its massively over-tyred. No 944 has ever needed tyres like that at the back, even the M754 cup cars got by with 245s and they had very different suspension...
I am confused by this as the standard rear tyres are 255 on 9" rims. I also had a set of 225 track tyres that came off a race 944 that had spun into the wall wearing 225 all round.

Thanks for that, it just reminded me why I'm keeping the standard wheels!

I've been out for a quick spin and what a difference the new tyres have made! (Admittedly the old tyres needed to be replaced but I've never been a huge fan of Pirelli P Zero's anyway.)
Thank you to everyone who offered their opinions.

The car is always driven enthusiastically and always seems to be well planted and it even feels as though the stability improves with increasing speed especially once past 100 (where legally permitted, of course).

They are still a little skittish when cold but seem to soften nicely after about 10 minutes

I have now dropped my Fronts (452s) to 28PSI, I found that they tramlined and were too finicky at 30 or 32.

Didn't the technical bulletin recommend 36psi when running 17's
I would not want to run below 30 at those sort of pressures if you run over a piece of debris on the road you stand a good chance of damaging the inner face of your alloy wheel.
