Was your consumption affected with all weather/season tires?

[Rapax]

I tried to find something about fuel economy and all season tires but I couldn't find anything, so...
How much was your consumption affected when you changed the tires to all season ones.
I have 18" stock Bridgestones now.

I have to do it in 1.5 months because that is the law, so I need to see what to expect.

Please write just for ev vehicles (preferably mg4), because we all know about our previous life ice cars ?

I put them on my zs and no difference.

I used winter tires during last winter and I didn't notice any difference on my MG4 Luxury.

I found this youtube vide very informative. It explains 10000 factors influencing economy and range

I noticed no difference with my Goodyear all-season tyres (or indeed Michelin Crossclimate on a previous car).

One thing that i am convinced makes a tremendous difference is tyre pressure. With mine set to 2.6 bar I got about 2.9-3.0 m/KWh. With them inflated to 2.8 when cold, the rate climbed to 3.6-3.8 m/KWh.

I'm wondering if the reduction in range in the winter is a lot to do with the tyre pressure reducing naturally as the ambient temperature drops. I blew mine up to 2.8 last winter when cold, and didn't notice a reduction due to temperature. There was always a reduction when raining, due to additional rolling resistance in the wet.

We've had all-season tyres on since last autumn, and we don't think there's much, if any, difference in efficiency.

There is a clear difference between winter and summer tyres, given they share all dimensions. But summer and all season do not differ much. What does differ is tyre wear in warmer months. All season wear off more quickly.
Btw, on my previous car I had 17 inch summers and 16 inch winters. Consumption was similar. Which is a good result because heating in the winter adds to the consumption.

Look at rolling resistance tests for your tyre of choice.
That is directly related to your average consumption.
Doesn’t matter whether winter or summer or all season, cheap or expensive, good in the wet or not etc…
Rolling resistance does not directly correlate to the type of tyre any more, certainly not for passenger tyres: you could buy an all season tyre with great grip all year round that uses less energy to roll than a standard summer touring tyre that performs poorly all year round.

Tirereviews.com publishes their rolling resistance test results in most of their group comparison tests

The classifications you will find on the labels are relative, measured with a standardized test using true energy consumption.
Also, the labels are specific for the type of tyre. You cannot simply compare a class D summer tyre with a class A winter tyre.
