I have a cultus 06 and currently using 175-70 profile
The ride is very very smooth and car looks great as well
Yes the steering is a bit hard as compared to the 155s but that’s acceptable as travelling of my car is mostly from Valencia to DHA via ring road
Average in city is compromised and with AC we achieve around 11-12 kmpl in normal traffic , while without AC it’s around 13-14 in city drive
