Energy saving tyres

They save energy by having a low rolling resistance (as already stated), but to achieve that they are made of rubber that is softer than an impotent males penis.
Consequently, if you catch something it does a lot more damage than something that can take abuse.

Softer rubber has more rolling resistance. Think about the rubber changing shape just as it touches the road at the front edge of the contact area. The more it squashes and conforms then the more resistance.

Yesterday the Memsahib had a brush with a kerb, a touch as light as a feather she assures me, and entirely the fault of the kerb. It is the second time in less than a year that an errant kerb has behaved thusly. The tyre cannot be repaired and a new one is required.

Just in case the contact is a bit worse than she realised, I'd suggest get the suspension checked as well.

In the floods I hit a kerb on a traffic island which was mostly underwater and larger than I expected. I had it inspected and a wishbone arm was replaced as one of the bushes had collapsed.

fuel prices are plummeting, as OPEC realises that the world is very serious about electric cars, so they're probably keen to pump out and sell all their oil while they can.

prices are estimated to go below £1 a litre next year so dont worry about energy saving quite so soon

Good news for The Government: they can reinstate the fuel tax escalator :mad:

But in the UK, we generate much of our electricity by ... burning fossil fuels!!!!!

We need to get our act together and build some modern nuclear power stations!

All this BS.......

Buy a car, stick some tyres on it, drive it. Compared to the cost of the car itself, energy saving and microscopic increases in fuel consumption, it's all a load of..........................

Low profile tyres and high performance tyres are the worst for side wall damage.
I once drove over a pen top and the metal clip went right through the tyre like a knife. Fuel saving tyres are only good value if you do mainly motorway driving, they start to work best, at speeds over 55 MPH They have very poor wear characteristics around town as the compound is prone to wear at low speed steering and parking. Fit an alternative if you can.

I had an old 1.4 Citroen fitted with Michelin energy savers. It was brilliant on the motorway. 80-90 all day regularly and easily. I did wonder if the tyres were helping.
They were a bit loose in the wet occasionally but generally good grip apart from on wet grass. They would spin even on level grass!. They were on the car when I bought it and were still ok 30,000 miles later.

They make sense if you have an already fuel efficient car and care about economy.

I wonder if OPEC has really decided to sink the petrol prices by oversupply just the screw with the Russian economy.

More likely than your previous claim about electric cars.

Have you seen the sales figures of EV in the UK?
On average this year 1,000 a month are sold.

In comparison Ford sell 10,000 Fiestas a month.

Energy price volatility is simple. The USA will be self-sufficient (discoveries + fracking) in 5 years. OPECs child-like price controls are gone, so they are trying to outdo each other in sales at these currently "high" prices, not turn the taps down in their old game of reducing supply driving up prices. Equally there will be fewer spurious American boots in the desert.
The UK will be last to cotton on, drivers have a self-harming addiction for petrol and the UK government will have to realise PAYE taxation, is going to have to rise to account for the drop in oil based tax take.
