ER-3682 Twincharged October 3, 2011 Share October 3, 2011 Probably your sidewall is too soft? What tyres are you using anyway? The stock Bridgestone RE050A. ↡ Advertisement Link to post Share on other sites More sharing options...
GemLeo 1st Gear October 4, 2011 Share October 4, 2011 i pump 36 on my bs s001... after 1k km.. it drops to around 34. Link to post Share on other sites More sharing options...
Monoswift Clutched October 4, 2011 Share October 4, 2011 Sorry do not get what you mean. Though my stock rim is 15 inches, I changed it to 17 inches e moment it with me. So powerful or not, it quite e same for me. Am more concern on e grip of it and too believes getting e right tyre pressure will increase e life-span of e tyres. maybe he meant loses abit power in pick up ba..coz 15-17 ma..so maybe weaker and slower pick up compare if your stock is 15"..

Joel4559 Neutral Newbie October 4, 2011 Share October 4, 2011 Hi, My car is a mazda 3 running CSC 3, currently running 38 PSI on nitrogen all round. Any Comments on this settings? Should it be higher pressure on the front given the weight of the engine to maximise grip and tyre life? Have pushed it to 40 PSI, seems lighter on the petrol, throttle and $$ haha Link to post Share on other sites More sharing options...
Jchuacl Clutched October 4, 2011 Share October 4, 2011 Then probably u'll need more hardcore BS tyres to suit your car. The stock Bridgestone RE050A. Link to post Share on other sites More sharing options...
AL5509 Neutral Newbie October 4, 2011 Author Share October 4, 2011 Sidewall for this tyre is a bit soft, you can try 240/230 for a start. ya, I heard that e side-wall of this tyres are soft too. So increase e tyres pressue will help 'harden'/stengthen e side wall? I pump 270 for all 4 tires. hhmm 270? Sound alot from what recommended. Not doubting your knowledge on this just 'shocked' as do not know it should be so much than expected. Link to post Share on other sites More sharing options...
Jchuacl Clutched October 4, 2011 Share October 4, 2011 To reduce flex. That pressure is used by the R which is originally on 17, so should be ok. You can plus minus a bit from there but not too much. ya, I heard that e side-wall of this tyres are soft too. So increase e tyres pressue will help 'harden'/stengthen e side wall? hhmm 270?

Satria_neo Clutched October 4, 2011 Share October 4, 2011 Tyre pressure is affected by your car weight and travelling speed. Its not affected by tyre size/profile. What happens is only you need more or less air to achieve the desired pressure. Link to post Share on other sites More sharing options...
AL5509 Neutral Newbie October 4, 2011 Author Share October 4, 2011 maybe he meant loses abit power in pick up ba..coz 15-17 ma..so maybe weaker and slower pick up compare if your stock is 15".. It does make sense but there will always be a trade off in both ways. Changing from 15 inches to 17 inches does caused a increase in fuel consumption n maybe slower pick up... But it somehow improve e gripping for e car as more rubber on e ground. Mine is not a super fast car so do not think will affect much on e pick-up (at least for me) :p Am more concern about keeping a longer life-span for my new tyres now by apply e correct/ideal tyres pressure.

VenomMX 4th Gear October 4, 2011 Share October 4, 2011 Guys then what about those nitrogen filled tyres? Can still go petrol station and pump? Or must go back to workshop to refill? Link to post Share on other sites More sharing options...
AL5509 Neutral Newbie October 4, 2011 Author Share October 4, 2011 Guys then what about those nitrogen filled tyres? Can still go petrol station and pump? Or must go back to workshop to refill? Heard nitrogen is better but again if not wrong, it is highly recommended not to mix with 'normal' air (those from petrol station). For me, i find it very troublesome n somehow costly to maintain as i know it not free rite to top up w nitrogen thou it is a monthly refilling if not wrong.

XenonWhite 1st Gear October 4, 2011 Share October 4, 2011 I pump 270 for all 4 tires. Me too... 270kpa on all 4 tires... been doing that for 4 yrs plus and driven up to Genting and back.. Link to post Share on other sites More sharing options...

Hiphiphoray 6th Gear October 4, 2011 Share October 4, 2011 (edited) I have GR-90 tyres running with this exact profile. (225 x 45 x 17). Pump 250 all round. Re-pump about once a month. i notice it would have settle at 232 thereabouts when i re-pump. Edited October 4, 2011 by Hiphiphoray Link to post Share on other sites More sharing options...
Satria_neo Clutched October 5, 2011 Share October 5, 2011 Actually, the sticker on your car is just a guideline. Some tyres performs better with more pressure, other may be less etc... It also depends on road conditions and weather etc...Even weight and speed also plays a part. Thus you would have to experience a little to find the best for your car. Eg for me, manufacturer recommends just 210Kpa for my front. But I find it way too soft and sluggish. My tyres perform best at around 235. Anything above 250 is too hard.
