**IMPORTANT**

You *MUST* always put the speed rating as stated by the manufacturer on the car, irrespective of how fast you drive.  You may invalidate your insurance otherwise.

Not strictly true. You can go up but not down. Similarly, you can go wider but not narrower. However, your profile must be the same.

If you go wider without altering the profile the speedo reading will be out.

[Mr Skrunts]

Any alteration from the standard spec.  Tyres, suspenspention, engine, running gear or body work should be mentioned to insurance.  In the event of a claim the insurance could well be voided on a non standard car.  (and we all know how petty insurance companies can be - dont we.  )

[Mr Skrunts]

IIRC load index is also important , I believe my falkens are 91W , with 91 being the index. I know there are higher indexes available but I believe if you go for a higher number you get into re-inforced sidewall tyres and ride quality suffers.

The higher the index number the more weight the tyre can support.

In reality 99.9% of people dont understand all this gobbledegook (and nor do I really!) so best bet is replace with like for like.

What if they were the wrong tyres fitted to the car before replaceing like for like.  :-/

Agreed. Whilst common sense might tell you otherwise, if you don't mention something to the insurers you are stating that your car is factory spec.

If you subsequently land that insurer with a large bill they will go over your car with a fine tooth comb until they find something like an incorrect tyre spec.

I have the 3,0 MV6 with low profile tyres, I hate the ride, if you drive over some snail poo your fillings come out! I take it is OK to put normal tyres on from it from a 2.2CD? Might soften up the ride somewhat.

One of the reasons I bought the 2.2 was the sensible wheels-I hate low profiles for the bumpiness and kerbing 

Does that mean a 4-pot finally has something over a V6

I do find my 2.2 is smoother on a run than mother tunnies 3.0 Elite Estate, more rubber to absorb the bumbs in the road i guess.

This warrants an OOF press release-an advantage of a 4pot over a V6 (besides simplicity, economy, etc.....)

To OP - its in the back of your handbook .  Prefacelift 225/55/16 (only fitted to elites) were Vs. May have changed for facelifts.

I think The Tourer and Reflection variants had them fitted as standard.
