yes u can install...for u in few days i will tell u the exact cost as i m finding person around daily
plus if u talking 165\70
165 means the width of yr tyres..the bigger width u have the more grip u have....like u must have seen 205 in 95,98 and new civic models with 17 inch rims
and /70 means the hight of yr tyre...the higher the hieght u have the batter u have the comfort....but as u get lower hight like low profile tyres with /50 u will have batter grip but suspansion will be damged ...
