Dynamic Handling Pack

[Chris Skelton]

The correct tyre pressure for P Zero's [Asimetrico] given with my 17" Lex. Wheels

40 psi front---52 psi rear

52??!!!Sounds as if it would reverberate!

[ROYT]

That's what I expected!!, but it's only slightly different than the original ride.

This is the list of tyres given with the wheels [17" Lexus]

Continental CZ91---40 front--49 rear

Pirelli P 700-Z-------40 " --52 "

Pirell P Zero---------40 "------52 "

Bridgestone RE71---41 "------50 "

Bridgestone S-01---41 "------50 "

Dunlop SP 8000----38 "-------49

Michelin MXX3------34 "-------43 "

Wow! I'm on 31, you're on 40 to 52?

Sounds like one of those would be dangerously out. Now I'm worried, but I'm reluctant to even try to put 40 never mind 52 into my tyres.

Seriously confused . . .

Or could this be why the ride is not quite as smooth as I would like it to be (or is that the other way round)?

[ROYT]

I forgot to add the tyre size 235/45 ZR 17

[8 J x 17 ---[offset 40]

Ah, OK (maybe). I have the 245/50/17's like CDM said.

Still not sure whether 31 psf is right though . . .

up to full loaded weight .....fat peeps plus bags? 44/49

225/60 r16 97w

Verrry interesting! Do the Pirellis cause more road noise? (Can you GET Dunlops in that size?) I guess it depends on what you want from a car this size. Is it bought by folk who want the comfort? Can't see TOO many sub-30s BMW aspirants after a LS 400, so 'dynamic' handling not so much a priority. Anyway, the standard car handles pretty well already, in the odd times, post United win, when elated I whizz home a bit more 'dynamically' from the pub...sorry, TV lounge. :)

OE Dunlops very quiet so Pirelli's slightly worse, but not bad. As I said, developed for Jaguar so well suited to Lexus.

The DHP wasn't meant to be super sporty, just look better and be a little sharper and more agile. However, people took to it and at one point it was making up 25% of LS sales !

For use in the UK, always use the 4 people, up to 100mph figures - those superhigh values are 5 people plus luggage at max speed in Germany.

I suggest: 225/60x16 set at 30 psi F+R, 235/45x17 set at 33 psi F+R and 245/50x17 at 33 psi F+R for cars up to 99. Add 3 psi for "sporty driving" or speeds over 100mph.

[Chris Skelton]

Just saved me a job! Already at 30psi on both cars.....and +100mph in Britain v.rare, (unless you're a government minister? :D )
