ok interesting to know

one last question to members, what is the rule of thumb; when to change tires?

mine was based on duration.. for 3 years i got the car never change b4, basically my friend told me the tire still looks ok but i guess out of safety id rather not the risk la

what about you guys??

With no criteria set by TS, I would say PS4 hands down is the better tyre.

The old saying was tires would last for 5 years and then it will start to degrade. However lately I came across a Continental website which claimed their tires could last till 10 years. I'm running on a set of Conti CSC5 which was manufactured in 2014. I thought I want to change but would instead just test it out to see if it would indeed last 10 years, since its only a weekend car.

For safety, it is still better to check the thread depth indicator. Even when the indicator is level with the tire surface, you still have 2-3mm thread which is ok for pretty much anything except aquaplanning maybe more severe. If low mileage, I used to encourage my parents to change every 5 years (provided you get fresh tires everytime aka same year manufacturing as the time you purchased it).

Not really. Nitrogen is really a convenient. Even though air is >70% nitrogen, there is still 20%++ of fluctuation. I have tried nitrogen on few occasions and the fluctuation is really minimal. 1-2 PSI after few months which is nuts compared to air only.

It depends on the tire durability, your driving style, type of car, and average mileage travelled. With combination of these factors, it can last from just a year to even 5-6 years. So cannot really say change every 3 or 4 years is a must for all. You just need to observe the condition. For example, some tires tread can finish faster before rubber becoming hardened/cracking, some have treads that can last very long but rubber can start to crack/hardened. Your driving style and average distances are also a major factor in this.

For example for my driving style (faster and more aggressive than average), mileage travelled (+/- 80-100km/day), my type of cars and tires (high performance tires) usually my tires last just around 3 years or between 40-50k km.

physically inspect your tyres, if almost botak then it's time to change, SUV tyre can last around 50k with moderate driving behavior (no vroom vroom)

Here are my sharing after using 3 sets of Pilot Sport 3 and a set of Primacy 3 ST. The new version 4 should be improvement over the version 3. Both are good tyres designed with different purpose in mind and their difference shows when you test them to the limit. For daily drive I’ll still go for primacy although the slight disappointment during genting run, it’s still a decent tyre. If you want to bring up track day then these tires isn’t for you... go for slick tyre instead.

Primacy series:
+long lasting thread life(~60k km)
+silent and comfort(marshmallow like)
+good grip
+cheaper
-soft tyre(some ppl like it hard)
-not recommended for super hard driving(it still can but ESP/ESC will light up often)

Pilot Sport:
+superb grip(pilot super sport lagi powahhh)
+hard corner/touge oso can
-Noise, vibration, harshness is acceptable but definitely lose to primacy
-shorter life but still acceptable(~40k km)
-pricier

Agree. I changed from primacy 3st to primacy 4 immediately feel the tyre is noisier and stiffer. But handling is still good.
