Dunlop SP9000 Tyres
Discussion
Just fitted SP9000's to mine not really had a good oportunity to test them out yet, but so far I haven't noticed any difference from the SO3's, although I did have the back end out a few times when pulling off from junctions, but put this down to the rears being very worn.

Paul.

Not a clue what SP9000's would be like on a chim but i've just replaced the ones on my road slogger with them.
Had them purposely factory fitted when i brought it from new.
Have now had them on a variety of motors and they have proved first class

Hi
I have just fitted 4 SP9000's to my 4.0 TVR they are z rated tyres and are just about scrubbed in, like some of the other guys have said they are a bit unsteady at first but now offer plenty of grip. Great in the rain too... well as good as any tyre can !
I replaced the fronts a few months before the rears and was amazed by the front end grip, coupled with a couple of mil left on my rear Conti's, the handling was fun until I got my new rears.
I paid less than £100 per corner, which I though was very reasonable !
The tyres suit the car well, they have a great tread pattern (tyre perv alert !!) and have stiff rim protectors moulded into the sidewall, so make it wife parking friendly.
They are currently runnning standard pressures but may drop them 2psi based on what others have said in this thread.
The speed rating letter represents the top speed that the tyre is tested to, also a higher rated tyre will have better high speed stability, that is why a 1.4 hatchback has tyres that are capable of 149mph in a car that would struggle to see 120mph
Interstingly the following letters apply to speed rating
V = 149mph
W = 168mph
Y = 186mph
ZR = 149mph
Apparently the ZR rating was introduced when car manufacturers started fitting 16" 17" and 18" tyres as standard.

Whoops.... meant to point that out
And you need to scrub 'em in for about 50 miles
Speed ratings V, W and Y are replaying Z. Z is the old speed rating that indicated 149+ mph. Because cars have got faster and demand more from tyres these other speed ratings are gradually replacing the Z rating. You are even finding that "normal" cars, such as mondeo's are being fitted with W rated tyres.
Some tyres will have written on the tyre wall 205/55 ZR 15 88W. These fall in to the Z rating catergory but are W rated. The 88 number is the loading that the tyre can take, not too much of a problem with a Tiv.

V is not new and no change. W and Y have been around for a few years now and are an economy measure; they are speed rated as mentioned earlier in the thread and the tyres are stamped as a sub-division of Z rating. Z cariies on as before - what else will 200mph cars use? Similarly why use 200mph tyres on a 150 mph Griff when a V or W wil do

W will do, but not V as they are rated to 149 and Griffs (and chims for that matter) exceed this. I have confirmed this with a few insurers, as I'd be after the Toyos if I could, but they only make V rated 205 55 15s.
Currently the only make I can find that meet the size and legal requirements are the Dunlop SP9000.

This is not quite correct. V is OK as long as agreed with your insurance company and as long as it's suitable to the use to which the car is being put. I gather that quite a few people sucessfully use V rated tyres.
