I am replacing my tyres with slightly bigger ones , 245/70 16 and before I go ahead with the purchase online I wanted to check if they will fit the spare tyre well.

I cannot measure it as my car is at "the hospital having surgery" , so I was hoping you could be able to help...

The 255 55 18 is 29" , the one I am thinking of buying is 29.5" so my guess is that it should be OK , but I want to be sure.

I have Bridgestone Dueler M/T 245-70-16s on mine and the spare doesn't fit the well.

All I can confirm is that 255 60 18 does not fit, although the other four are fine on standard air.
You can compare your size with a tire calculator.

I went up from 255 55 18 to 255 60 18 and the tyre doesn't fit in the spare well anymore, even if deflated.

so basically I am doomed.

I was thinking of fitting a set of Cooper discoverer AT3 4S , but they are not available as 255/65-R16

I'm surprised by the comments that they won't fit as I have the 7J x 16 wheels on mine that uses 235/70x16 tyre size so would have thought the difference in diameter would have been negligible going up only 10mm in width. But if people have tried it then who am I to argue? One option that is available in 255/65x16 is the Grabber AT3 for around the same price as the Coopers. A bit noisy though. Depends if you really need an off road tyre as there are a few other options that give better wet grip and are quieter.

Actually, I am only after a good tyre with a "3 peak snow flake" stamped on.

My problem is that I need to travel to countries where it is compulsory a "snowflake" tyre (or alternatively Snowchains on board) during the winter months , so my idea was to get a suitable 4 Season Tyre.

here in GB is never too hot , is always too wet and in the past years we have been experiencing more and more snow, so a 4S would make some sense and.... I cannot justify having two sets of tyres which would be the correct choice if I was living close to the Alps.

I will look into the 255/65-16 range wich has some options (Yokohama/ Kleber), the tyres are not "AT" but might actually be what I am after (I hope...)

The issue isn't width, it's diameter. Your 235 70 16 tyre is 29" diameter which is same as standard. The 255 60 18 that I've got fitted are 30" diameter.

I know it isn't the width but I was thinking that as the diameter is related to the width (with the same aspect ratio) then 10mm extra width wouldn't make too much difference to the diameter. But it does, a 10mm increase in width on a 70 series (height being 70% of the width) tyre would increase the radius by 7mm so the diameter by 14mm, or 9/16th of an inch.

For the same reason as the OP, I needed the 3 peak snowflake symbol too and went for Vredestein Quatrac 5 and I've found them to be superb in the wet and very good on snow. Unfortunately, they aren't available in 255/65x16 so I would go for the Kleber Citilander. They have the required symbol, the same C C 72 EU marking (far better than either the Cooper or Grabber) and a very similar asymmetric tread pattern to the Vredesteins.

Went ahead and got a set of Kleber CityLander.

all well, the car is back to the 16" and after a 1/4 of a Mile I had a smile across my face, the old RR has never been so nice... it feels like driving a cloud.

while fitting the 255-65 R16 in the well i did notice it is a tight fit, no way anything bigger than 29.1" fits there.

Anyway, I told my tyre supplier I wanted to put five 255 65 r16 Range Rover P38A tyres on my wife's Fiat 500 and he said it was impossible... yeah right...:mrgreen::mrgreen:

Not counting the irritating fact that each tire manufacturer is a different size for the same numbers on the sidewall.... Here is how you work it out:
255/55 18 for example
255 x .55 = 140.25mm.
x2 as there are 2 sidewalls = 280.50mm
280.50 / 25.4 (mm per inch) = 11.04"
11.04 + 18 wheel diameter = 29.04" total height.
