The category of 195/65-15 tyre profile has a lot of variety in a number of brands here. Surprisingly, stockists here have very less variety of 185/65-15 profile and thus less profit margin if in case it's available. The demand too is of 195/65-15 being a common profile. Therefore the shopkeepers push you towards 195 instead of 185. So, dear friend, rest assured that it's not the profile that's superior, it's the lack of availability or variety that you are channeled towards 195/65-15. Okay, now here's the deal:
the next best optimal profile after OE recommended tyre size (175/65-15) is 185/60-15, followed by 185/65-15 and finally 195/65-15. Some options that you have right now are:
185/60-R15: Bridgestone Ecopia 200 Series (Non-Smuggled): Rs.34,000/-
185/65-R15: Dunlop SP300 Series (Non-Smuggled): Rs.28,000/-
185/65-R15: Michelin XM2 Series (Non-Smuggled): Rs.37,500/- Made in UK
If I were you I would have settled down with Bridgestone Ecopia 200. But that's just me. Your mileage may vary.
