i seen many civics on 18s, but most people recommended it for daily driving due to low profile tires and it will give you a high risk of the rims getting bent. bent rims are expensive to fix. plus resale value for 18s for 4x100 lugs are not good. couple months ago, some guy was trying to sell some near new 18s volks te37 for about 3 months, he had a hard time selling it. he even drop the price down to i think it was 1,100 and it still took a month for the sale. 18s volks with tires are atleast 2500, and he had to sell it for less then half.
