well, infact, im not really sure is it advisable but i know mine recommended is 230F/210R and i always pump to 240F/220R on my 16".... what really shock me is the other day, saw one guy pump 300 for all 4 tyres for his 15"... .. i was behind him and saw him pump it till it hits 300kpa... if im not wrong, tyre has a limit and anyone here pump till that level??...
actually, that is not all ... after me, one guy with a bicycle waiting after me for air pump also... when i board my car, saw him adjust till 300kpa also and pump his bicycle happily and the tyre seems can take it...... not too surprise about the car but a bicycle tyre also can take 300kpa?..
