Side sticker recommended 220 kpa or 31psi.
I used to pump at 200 due to some advise to pump lower than the recommended spec, thus my old tyres suffered the same fate like this, thus there must be my fault of doing it wrong.
, and very dangerous at prolonged high speed/distance traveling as tyre surely gets hot faster .... leading to tyre burst whilst in motion.
Lately I am pumping at 220/230 again when others commented that the car seems to have not enuff air. Asking around, many ppl advised that tyres need to change at the 2-3 years period, but I am not satisfied with the answer due to mine having low mileage (the older tires have almost 35k km in 3 years, so maybe its understandable that its worn out and i never rotate it before).
That's a common myth spreading around.
Tyre manufacturer recommends tyre replacement only when tyre tread is 1.6 mm or 10 years post production in normal use.
My XM2 pair was replaced at about 115,000 km usage when tread depth was 2 mm , the tyre age was around 7 years.
Currently another pair of XM2 is at about 60000 km usage/tyre age about 4 over years all running at 300 kph (44 psi) where manual says Front 31 psi Rear 35 psi... ..... still in use with about 3-4 mm tread depth.Won't change them until 1.6 mm or so tread depth.
I did not rotate this tyre cos usually ppl advise to only rotate above 10k km.
I stopped rotating tyres
a long long time ago, like some 10-15 years.Bitog on tyre pressure.This post has been edited by zeng: Aug 28 2019, 10:19 AM
