I recently went to all tyre shops in famous markets, cant find any michellin in 165/55 or 165/65,
by the way low profiles tyres look good, but my dear there is lot more to consider, low profile tyres have v poor response in wet weather city, especially pindi or isd, there is more aquaplaning happens on low profiles, thats y they become somehow risky, instead 165 i wd recommend go for 175/65, they will look much better and have lot more grip, which over comes the alto's existing low road grip problem.
Regards
