QUOTE(raayeop @ Oct 3 2017, 07:18 PM) this is new... You saying that 155/70r12 tyre has the same contact patch as 245/35R18 if the pressure is the same.... I must had slept during my form 4 physics class... QUOTE(BelaCHAN @ Oct 3 2017, 08:35 PM) Lol, probably did the same thing as you bro, TOTALLY dozed off! =D Took some times but I found a good explanation. Like I said before the reason for better grip on wider tire are not because wider tire has more contact surface if the car weight and tire pressure are the same. Other factor contribute. the F1 car use wider tire for different reason too. Hope this article explains it: https://www.6speedonline.com/forums/996-tur...read-first.html

Hope this article explains it: https://www.6speedonline.com/forums/996-tur...read-first.htmlThis may be applicable if the tyre is a flexible thing like a balloon.. the contact patch is determined by the weight (force from outside) versus the pressure (force from inside)... Tyre by itself is a rigid structure... following that person calculation whereby the contact patch is determined by the pressure, then how do you explain the contact patch for the tyre when it is not installed? Is it zero inch? Doesn't it touch the ground? Bring a piece of glass to a friendly tyre shop.. Ask them to give you two tyres.. One a 155 width and another 235 width (do not install them or put any pressure).. Then press the glass on top on the tyre with a fixed force (say 5kg weight).. and calculate the area of the tyres pressing against the glass.... Do let us know your finding....

Like I said the car weight is same, constant. The tires are all same pressure regardless size. I can guarantee the contact surface area would be the same. You can ask any professor in Physics Pressure = Weight/Area. If Weight and Pressure are constants, the Area must also be constant.

But if that makes you happy, why not....

QUOTE(spreeeee @ Oct 3 2017, 03:24 PM) Original tyre is 175/65/14. What you guys recommended for upgrade but still maintaining the fuel efficiency. Any opinion please? If it is similar to AXIA, then we can follow this thread: https://forum.lowyat.net/topic/3821265why dont you try 185/60/14? i may be wrong, it seems 14' dont have much choices for 185/55. hence profile of 60 is the best, comfort and good handling. FC wise, definitely will reduce but not significantly. I like bezza too and also feel, 175 is totally insufficient.
