28 front 38 rear, think the tyre's should be 255 70 R16's but wheel wobble could be balance or as Wodie posted, steering damper.
That's the official figures. I use 34 for the rear when empty and they seem to run OK. I normally have the fronts a little harder too, maybe even 32 and no issues.
Just occurred to me. I had some of those flat wheel balancing weights on the inside (hub side) of my 16" rims. When I switched to Britpart brake calipers they were square rather than rounded. Noticed but with 18" rims on it made no difference. However, when I put the 16" rims on the corners knocked the wheel balancing weights off as there wasn't enough clearance. Could be you have a similar issue?
Wammers, how do you tell the difference between a 7J and 8J wheels? My 99 DHSE came with 235/70/16 fitted when I bought it last year and they are listed in the handbook as a correct size for the vehicle.
Written on the rim, usually. Only the very early ones had 7J as they were left-over from the previous model. Yours is a later model so it'll be 8J unless someone has been messing about.
To find the perfect tire pressure for your car/tires, just draw a couple of lines across the treads on each wheel with chalk. Give her a short run on the road (hard surface) and see where the chalk has worn. If the chalk is most worn in the middle = too high pressure, if the chalk is most worn on the sides =to low tire pressure, if the chalk is evenly worn =correct pressure.
You can also get an indication of wrong to-in if the chalk is only worn on the inside or outside, then it is time for a wheel alignment.

You have the wrong handbook then. 1999 handbook wheels and tyres are 8J 255/65/16 or 8J 255/60/18.

PS Big shout out to the help I got from you guys on the CKPS crankcase sensor, got it repaired here and she now runs like a dream....hence ive found the wobbly steering at a higher speed 70 mph Than I could find before...
Using factory tyres 28 psi front and 38 psi rear. Different tyres may deviate a little but that's a good place to start. Chalk line across the tyre, drive a bit then see if rubbed off evenly.
