BMW - New tyres, spongy steering

    Somewhere between a review and advice seeking here!

    Just swapped out my OEM-replacement Turanza ER300 runflats for a set of Bridgestone Drive Guard - did the full set as 3 tyres were down to about 10/15%.

    I'm finding the steering isn't as tight or responsive in corners as it was on the old set; something which makes driving it that little bit less fun. Have tried playing around with air pressures a little with no difference really.

    Suspension is softer too, in a nice way - previous tyres tramlined a good bit and were very harsh on rough surface or ramps which isn't the case now, so that's the upside.

    Just wondering if anyone else has done the same and noticed similar results or should I be running back and asking for exchange here? Is there anything one can do to sharpen up the steering a bit again without swapping the tyres? Car's an 05 E90.

    Drive guard doesn't strike me as the name of a sporty tyre.

    Thats brand new tyres for you.

    A new tyre doesn't respond as well as a tyre with 3mm on it.

    Only a day, but still 200+km done so well broken in, I'd have thought?

    Really? No point in buying new tyres at all then I suppose.

    There's just a softer sidewall on the new tyres. Benefits are smoother ride, better in wet weather. Downsides are the steering won't feel as sharp, possibly more prone to sidewall damage from bad potholes or mounting kerbs.

    It depends what you value more. You have said it's more comfortable. Would you give that up for the sharper steering?

    Really.

    It's most noticeable on track days.
    But I also feel the difference in road cars with new rubber.On a dry road when driving on especially so.When you consider the thread bands/blocks on a tyre,9mm is going to flex a lot more than 3mm,this effects what is referred to by some as sharpness/handling.

    But it would be a bad idea to not purchase new tyres for that reason.One would have to consider,road safety,wet weather handling,stopping distances et al.
