2015 Defender 110 Puma 2.2 XS CSW Aintree Green

For the benefit of the OP, if he's still following, the General TR tyre pictured earlier is speed rated Q, 160 kph or 100 mph.

That is also a maximum and you don't have to drive at speed all of the time.

Tires specs are a pet peeve for me. In fact I used to live in Norway and there the tire spec is listed on your registration document (V5 equivalent) and at your MOT they check. I recall it lists size, load rating and speed. I had a long (but futile) argument with an MOT tested because my set of winter tires was fitted on different size steel rims so the car failed the MOT. Refitting the summer tires would not be legal in the winter either. I normally did the MOT in summer, but was selling the car. I postponed the sale till after 01 April so I could legally fitted the 'correct tires' to pass the MOT.

It was a Volvo and the speed rating was something like 180 kph, with 110 being the legal speed limit and the car not making that speed in the factory spec.

All this stupidity when rules meet reality, as I said futile discussion.

As it happens the tire speed rating for (the real) defender seems to be set at 130 kph, which at least is realistic!

That seemed more like stupid EU/European legislation trying to regulate things that don't need to be.

I believe, in the the UK, you can fit any speed rating tyres, so long as they are otherwise legal. However you cannot legally exceed the rated speed rating on public roads, even if within the legal speed limit.

i.e. if you wanted to run tyres with a K or L speed rating (68/75mph), then you can.

I am probably wrong, but I thought your tyre rating had to suit your vehicle manufacturers specification?

C&U regs say that for most 'normal' road vehicles, tyres must be rated for at least 70mph. 02' 110 TD5 Double Cab Rebuild Thread

2012 Defender 110 Puma 2.2 XS CSW Orkney Grey

I wonder, legal or not, what your insurers would say running tyres with speed rating under legal limit?

Cooper ST Pros for example with K rating 68mph. James

Insurance is a different question and not one of if a vehicle is roadworthy and legal to drive on the road.

There is a speed rating on all tyres and it is illegal to fit a tyre with a lower speed rating than your car's maximum speed. Any tyres fitted by Land Rover to the Defender have always had a higher speed rating than the vehicle was capable of .

Not true, you can fit a lower speed rating, most winter tyres are H rated for the oem fitment and the summer is v rated.

You can’t fit tyres with a lower load rating than originally specified, but load rating is very different from speed rating.
