Wah...if your tyres is 3 yrs old and was under-inflated for long period it might be damaged or bruised internally within the tyres oredi...
I suggest you seriously consider changing it soon with the rainy monsoon coming...we shouldn't skimp on tyres...
After spending the $50+K our family lives basically depends on just that 4 shoes pads to stop a car at 90Km/hr...
I remembered my Toyo tires skidding after about 20k km on the PIE under rain at 80km/hr.
Fortunately the car in front was several car lengths as i am basically a safe driver (i.e., my FC is at 15km/L)
Good tyres grip is not a luxury...it is an insurance for your safety.
I don't like to throwing money on insurance - but i know my family needed them.
Just look at the extreme - the horiffic crashes at NSH due to burst tyres...so many lives lost.
OK, take care now...
3 years, not sure whether during servicing they got or not... if they did help us pump, its 6 months!
I got the fuel system cleaner... whats up with the 2?
