Need Advice Regarding Tyre Upsize For Amaze

Hi , So i need some help regarding tyre upsizing for my honda amaze 2019 ( V Mt) it currently have mrf zvtv stock tyres which drove 43000 km (175/65/R15) as the tyres are almost seven years old i am planning to change it , so the question is

A. Should i go for 185/65/r15 for upsize , as most of the times my car gets hit if there is speed bump or pothole , does upsizing creates an impact of steering and suspension also i am planning a road trip to leh so upsizing will be good I believe.

B. Which brand should i go for - Yokohama earth 1 max ,Continental UC6 ,Bridgestone sturdo, Mrf Zlx ( i heared zlx are best in mrf )
