17inch wheels on 1986 Lux

Got my 17inch wheels fitted on my 86 Lux now and have been playing around with tyre pressures. Started with 34 front & 36 rear. Car was 'OK' but steering felt more pointy than before. Turn-in not that good & tramlining was evident. Reduced pressure in the front to 32 and, oh dear, Tramlined all over the place. Lots of kickback through the wheel...generally not nice. Car basically wanted to drive itself. Then tried 36 in the fronts...WOW ! No more tramlining! Steering feels good again (not much different to old 195's) with good feel and good turn-in. Don't think I need the 968 castor mounts for now.Amazing how much difference 2psi can make on the fronts. I fitted the new Kuhmo KU31 tyres and I have to say I am impressed. Ride is firmer than before, but ,more compliant than I was expecting having come up from 15inch wheels. Noise levels are very low and grip is impressive. Not tried it in the wet yet, but, the roads were greasy this morning and the car felt very stable. They look great too ! [:)]
 
Great news Mark!

Next time you are due an alignment, I should replace the caster bushes beforehand (they are only circa £40 each, sometimes less with special offers) and prepare yourself for an even better turn in. The new bushes have much less rubber and you can tell the difference.

I have Kumho Ecsta's on the rear of my Turbo and I find them an excellent tyre.

Lol! But hang on a minute Fen, isn't your car off the road again at the moment ;-)

Back on topic though I would second the castor mounts, they made a very worthwhile difference on my car. I have found 34PSI to be the best for my car through experimentation and is in line with many other people I've spoken to. I hate to be negative but I wonder if the higher pressure is perhaps reducing tramlining etc by reducing the contact patch. Probably unlikely I know, but it might be worth keeping an eye on how the centre of the tyre wears just to be sure?

Best regards,
Peter.

Let him have his moment [;)] After all, I did dish it out for a long time.

The shoe will be on the other foot when my 3 litre rises from the ashes [8D]
