    Hi all,

    My bridgestones have some life left in it so thought I will change them for new ones. I also want to upsize it and here comes my question on it

    My Punto comes with 175/R14 (Emotion), and I can upsize it to 195/R15 but E+ comes with 195/R15 by default and it generally is upsized to 205/R16 , So if my understanding is correct then my 175 can be upsized to 205/R16 too isn't it?

    Please let me know.
    Also other questions include
    1.) wider tyres better than slender ones?( I know of wider ones causing hydroplaning effect on water logged roads)
    2.) Is a length of the sidewall more important for the grip than wider tires.
    3.) I want more grip and a bit softer ride(a bit of tyre noise percolates into the cabin in BS) than my existing ones.

    PS:: I'm satisfied thoroughly with BS and planning on buying the same, but want to give others a shot as well.
    Surprisingly my BS lasted for nearly 40k it still has about 3mm, But i think it would be risky to continue with it anymore as its old.
