Four wheel drive/AWD

[Obelix]

Hi -- following up on this year-old thread, we did end up getting some all-weather tyres to see how well they would work in the snow. We figured if the tyres worked we could avoid having to get a four-wheel drive.

 

And then of course, just our luck, there was no snow this year, so we still don't know if they would work for us!

 

The only effect we've seen is that our gas mileage went way way down (almost halved). Because we had the car tuned at the same time, we're not sure if the problem was that the garage messed up the tuning, or if it was the new tyres.

 

We did expect to lose some fuel efficiency with the new tyres, but not this much. Does anyone with experience of all weather tyres know if this is normal?

 

Thanks again for all the advice!

I swap my tyres each year from summers to winters and never notice any difference. If you are truly getting half the economy then that means that you are dumping all that energy as heat in the tyres which means they should have melted off the rims by now. You will have another reason for the poor economy.
