But black, forums are about experiences & opinions. Which is most credible, it is up-to the reader? It's clearly stated in post based on my driving experience. Even if it's not an experience & an opinion who is certified by manufacturers? All are equally credible. One of Gen. Mgr. in our company with 60 lacs/annual package bought an i10 last year. It's FE can already put Ferrari Berlinetta to run for cover, he swapped some bigger lemon color alloys & wider tires on top of that. He looks shoulder riding an absolute joker, look at me, look at me.!! Yesterday he was telling me that with AC on, It's mileage is hardly 6-7 KM/Ltr in local Delhi drive. He is spending Rs. 500 for petrol everyday for his 40 KMs commute. I told him to get dispense with this cheap stuff. He can afford it so why not to go for for BMW/Audi instead of fantasizing it in some Chinese product. He doesn't have any problem with his car what so ever & clearly blames AC/bigger/wider tires in his i10 which dropped his FE from 10 Km/ltr to 6 Km/Ltr:mrgreen:. Fact is the cars with smaller & thinner tires are not meant to carry big/wider tires. If manufacturers haven't provided wider tires in them, they are not capable enough to carry them over in given conditions. Their suspension will be over in 6 months due to bigger RIMs & their FE/performance would go for a toss. It's obvious. Some one asking that question for Audi/BMW/Merc will be laughed upon. Smaller segments, if FIAT cars have them, reason is simple. Their suspension is capable & engine's are endured enough to match standard FE/performance & suspension can withstand tougher conditions. Simple, these cars meant to carry on such stuff because they are designed to. Why such a deep digging & blaming when scenario is self explanatory?
