What speed rating do the tyres fitted need to be?

After looking at the below, I presume Z, W or Y, but just wanted to make sure?

Thanks in advance.

Speed Rating Mile/Hour Kilometers/Hour
N 87 140
P 93 150
Q 99 160
R 106 170
S 112 180
T 118 190
U 124 200
H 130 210
V 149 240
Z 150+ 240+
W 168 270
Y 186 300

Hi Mr Plow, The handbook says Zs but some tyre types are not available at this rating.
I have Ws I think but I cleared this with my insurance company. So I am Ok as long as I dont have an accident due to tyres when I am travelling at 150 mph or above my fitted tyre rating.

It is very important that you let your insurance company know if not the recommended rating.

As WOO51E,

I'm running W rated tyres and have let the insurance company know as they are not what the manufacturer recommends (mainly due to availability of that rating tyre)

You're just making life more difficult than it needs to be for yourself and others. W and Y are sub-divisions of Z and as such are what the manufacturer recommended.

yes i had all this worry looking for tyres and had a long chat with the guy at the garage. I don't remember the whole conversation, but as well as speed ratings it's something to do with vehicle weight too, so a Z it good for xxxmph, but so is a Y or W if the car is lighter. As a Chimaera weighs about as much a weeks shopping for the the wife it's safe. That's the jist I got from it anyway.

I can't even remember what speed rating the T1Rs that eventually went on my Chim are, but when I spoke to my insurers (Manning) they were quite happy for me to drop down to a V-rated tyres. I think 149mph is adequate for road use and the loads generated by a Chimaera at those speeds are unlikely to be much more than any other production car capable of 149mph...
