OK, so I have now dropped the pressure to 31F (R same as before at 34) and it seems to have made a significant improvement. I have covered a further couple of hundred miles on dry roads so it is also possible that the tyres are scrubbing in to my geometry, although if they are it's not that detectable, since the improvement (reduction of tranlining) occurred as soon as I reduced the pressures by 2psi. I'll probably drive it like this for a while and then try 35psi, and then 33 psi again to see what difference it makes. I may even try 30psi to see if this yields a further improvement. Much appreciate the pressure tip - so far it seems to have done the job. regards Nick

About 400 miles so far. I will put another couple of hundred on and try the tyre pressure variation and let you know how I get on. The 944 Turbo came with an LSD but it wasn't available AFAIK on the 968, although it's possible the 968 Turbo had one. Nick

No problem. I'll have a play with the tyre pressures and report back with the outcome. regards Nick

Not sure I understand. They are directional, but surely you could remove a tyre from a rim which has been fitted to the NS of one vehicle and refit it to a rim which is destined for the OS of another vehicle. That is, unless they are directional and have a face which must be fitted towards the outside of the vehicle. Is my understanding correct? regards Nick

Tony, hi The tyres are exactly the same size as the originals and are mounted on the same rims front and rear. I'm running the pressures which seemed to suit the Contis, i.e. 33F and 34R. Geometry was left as before. I'll try the pressure change and report back. One thought I did have was that it is possible that the tyres, which had about 1,000 miles on them, were mounted on my car on the opposite sides to those which they were mounted on the car to which they were originally fitted. (That car was a 968, which has the same "chassis" as the 944 of course). However, I have driven around 400 miles on them since they were fitted and the tramlining effect is just as pronounced now as when they were first fitted. Thanks for your input so far. regards Nick

They're GSD3s. regards Nick

Hi all I am new to this forum - it was recommended by a friend. I have a 1990 Porsche 944S2 which until recently has always been fitted with Continental Contisports. I have just swapped them for a set of nearly new (less than 1,000 miles and manufactured in late 2007) Goodyear Eagles (F1s, I believe), which were acquired from another friend. The car seems to tramline much more with these than with the Contis. I'm running the same pressures (33F, 34R). Any thoughts? The new tyres have definitely taken the edge off the steering feel and accuracy. regards Nick
