"V" rated tyres on the back?

Will I be ok with these do you think? Never go over 100/110 (kmh you understand 
) in short bursts 
) in short bursts V tyres are rated to 149MPH. Tricky one really Wyn. Insurers can get really funny if you have tyres rated below manufacturers spec. Your's started out life as a 350? now is 460?
I know i have to have W or better on my 420
Hi Wynn, dickymint has a good point. The big risk these days is what might your insurance company use to reduce, or even get out of coughing up their precious cash should the worse happen.
My 350i handbook lists 'V' rated tyres, I guess yours does too, but it would be well worth getting their acceptance of the tyres in writing if different, just in case.
I've met a fair few insurance company assessors over the years and I'm sure they get a bonus if they manage to reduce a payout. Most of them seem to be former mechanics or body shop supervisors and are very good at spotting anything that isn't standard.

Hi, don't normally post in the Wedge section, but a cautionary tale....
You are buying a perfomance package when you buy tyres, not just a max speed rating.
A few years ago I did a trackday (noddy little airfield circuit) in a friends TVR M Turbo with my Taimar Wheels/Tyres. THe Turbo specified V rated tyres, my tyres were H rated (on the old system that was up to 135mph, in those days V was the highest rated tyre you could buy at 135mph+)
At the end of the day, the tyres looked ok at a superficial glance, but on further inspection, whole tread blocks were missing!
Now we never went above about 90mph on the day, but obviously a Turbo accelerates a bit quicker than a Taimar
Personally I would put on the best tyres you can afford

TVR specified V rated tyres for the 400/450 models, although I personally have always used Z or W rated. Obviously top speed is not the only factor determining an appropriate tyre - acceleration and deceleration forces, lateral loading, vehicle/driver weight etc. I would think that it would be easy to argue that as long as you haven't got a power output in excess of the maufacturers quotes (how many Big Wedges really have?) then you could legitimately use a V. Whether you feel comfortable doing so is another matter.

Not strictly to do with speed rating, but there have been some very enlightening tests done recently on motorcycle tyres. It has been shown that the super sticky high performance sports tyres give no better grip than touring tyres in normal use. Touring tyres also last much longer. The main reason for this is sports tyres need to be worked very hard, all the time, to get and keep the optimum working temperature in them. Not easy to achieve on her majesty's highway!
Could it be argued that a car tyre approved for sustained speeds of 150mph+ but only used in normal driving conditions is at the same disadvantage to sports bike tyres?
Leaving track day use out of the argument for now, what do you think? I've not seen similar tests done on car tyres, about time someone did. Or have they?

Not trying to skimp or anything but my local tyre man can't get the Z's from his suppliers, only the V's. If they'r ok I'd rather give him the custom. 
Have you tried a few of the web based tyre places?
The must be available from somewhere - what size / rating are you after - I'll have a look around Birmingham for you
As someone else has already suggested - it might pay to get in writing that the rating you can get hold of are OK?
here in my country you are more or less "forced" by the mot to use the correct tyre size, including the right speed-index. there isnt any discusion with the mot-tester and even not with the insurance to fit e.g. H-tyres instead of V ones.
you can do it, but involved in an accident, you automatically loose the complete coverage of your insurance.
is it worth? it isnt!!!

According to the owners handbook V rated tyres were used as standard on 350i.
V = For vehicles with a speed capability not exceeding 240 Km/h (e.g. 225.55 R 15 91V
VR is very different.. = For vehicles having speed capability over 210 Km/h (e.g. 195.50 VR 15)
Any thoughts?

Re-read Dicky's post and you may wish to revise that.
