riding comfort?????

[j_gasmen]

mga gurus,

asko ko lang po, nagpalit kasi ako ng size ng mags from r14 to r15, I noticed that the riding comfort changes. If I change the coil spring ba with stock shock wala ba maging problem? gusto ko rin kasi sana mag lower atleast 1.5".
kelangan pa ba palitan ng shock or just simply change the coil.

thanks,

[boy_tino]

puede na rin siguro mag palit ng lowered spring pero kahit papaano makararamdam ka pa rin ng konting tagtag kasi iba pa rin ang laro ng stock na shocks mo sa lowered shocks dahil magkaiba ang pressure nun.

isipin mo ang stock na shocks ay medyo may kahabaan tapos yung stock spring na sumusuporta sa original shocks mo para hindi agad agad bumaba kapag nadadaan ka sa pangit na daan or pag marami kang karga sa kotse mo.

ngayon kapag pinalitan mo yan dati mong spring ng lowered spring ay magiging parang magiging puwersado na ang stock shocks dahil parang masyado na itong nakaadvance sa ground ika-nga nawalan na sya ng buwelo.


kung shocks lang papalitan mo tapos yung spring mo ay gagamitin mo pa rin ang dati mong original na coil halos ganun pa rin kasi ang mangyayari magiging matigas sa lowered shocks mo ang stock na spring mo.

tandaan mo iba pa rin ang balance pag dating sa comfort riding.


ang tanong ko lang naka low profile ka ba? anong series ng goma mo?

Of course the ride will change. Swapping wheels for bigger ones has more to it than just aesthetics. There's less sidewall on your new 15" wheel + tire combo vs. the old 14". Usually you should notice it rides stiffer.

my new wheel is 55 series. does also effect on the strut bar that I install?

medyo magiging stiffer na nga ang riding mo sa gayang klaseng gulong at isa pa lalo na kung masyado pang mataas pa sa nire-require na hangin or pressure ng gulong mo.

tignan mo ang gulong mo kung ilang PSi ang kelangan na ikargang hangin.

tanong ko lang ilang araw na ba yan goma mo saka yung binili mo yan ordinaryong hangin lang ba ang ikinarga sa gulong mo or nitrogen air ang ikinarga?

kasi yun iba kong kaibigan naka 55 series at naka nitrogen air sa gulong nila hindi naman daw stiffer ang ride nila.

No.

The strut brace will only have an effect when you turn into a corner. That has absolutely nothing to do with ride quality

another myth on the loose... nitrogen on tires does not make your ride less stiffer...

na-experienced mo na ba?

kasi kaka experienced ko lang kanina ang pagkakaiba ng naka nitrogen at naka ordinaryong hanging lang.

nasubukan ko yan sa dalawang parehas na kotse (honda civic ESi) at kapwa naka tires na bridgestone turanza (195/55 R15) at ang may ari ng kotse na yan dalawa ko ring kaibigan sa parehas na lugar dito sa lugar ko (QC) at sabay din bumili sa mismong honda.

ang napansin ko ang pagkakaiba, medyo stiffer ang naka ordinaryong hangin lang samantalang yun naka nitrogen as medyo komportable ang riding ng iikot ko ang sunud-sunod ang dalawang kotse iisang kalye, same distance and same road condition.

Do you know what pressure is inside the tires of each car?

Regular air is 80% nitrogen. There's no difference in the compressibility of nitrogen versus ordinary air. The advantage of nitrogen is that pressure increase due to heat is lower, since pure nitrogen doesn't heat up as quickly as ordinary air (though it eventually will).

I've had nitrogen inside my tires... on several cars. On a sedan with 45-55 series tires, the difference is negligible... on a truck with 65-70 series tires, it seems softer at first... but after a while, when switching to ordinary air, you can't tell.

I'm a recent convert to nitrogen, and yes I was also a skeptic for a pretty long time. It does seem to be more resistant to temperature changes, although as you said it can only hold its own against outside temperature changes for so long.

I'm presuming the real reason why it's more resistant to heating up and pressure increase is because the water vapor has been removed or reduced somehow. Basically it's "dry air" with the nitrogen proportion increased.

On my Jazz's 45-series rubber, I recently had my tires filled 36F/33R on nitrogen. I was genuinely surprised how well the car rode even with such high tire pressures - it rode slightly better than on my usual 32F/30R pressure on compressed air.

On a drive from Paranaque to Nasugbu loaded with nitrogen, I measured the pressure difference - +3F/+2R.

Just sharing my feedback.

thanks for all your advise, actually one of my friend advise me to change my my ordinary air to nitro. as his experience mas maganda nga daw ang rides nya kapag naka nitro.

Better if the starting point is the same. In other words, you have 36/33 both on nitro and regular air. Lower pressure in the tires initially will allow them to heat up more due to more sidewall flex (I always ride around on 35-33).

There is probably something there, but I've tried it on many different cars, and I've never felt the difference to be worth the extra money. But then, since I drive on the SLEX everyday and run over tons of potholes and ridges, I'm constantly checking my tire pressures, whether I'm using nitro or not.

Niky,
I've ridden 37F/35R on compressed air (vs. 36F/33R on nitrogen), taking advantage of the reinforcement of my extra load-rated tires (+5 psi from stock). Trust me, the "extra load" pressure is only really advisable if you're anticipating a lot of heavy passengers or cargo Ride is uncomfortably flinty for passengers at that pressure, although I can still stomach the harshness.

As for temperature...the 37F/35R combination on air I've already driven to Subic. Measuring the pressures after stopping, the pressures spiked 41F/37R (+4 and +2 front and rear).

Not the same as testing on 36F/33R on air but it's just about as close as I have from real-world personal experience

The 36-33 reading, was that from the pump, or from your personal gauge? If it was from your handheld gauge, then there might just be something to it.

Seems like some scientific back-to-back testing is in order...

Could be possible the effects are more noticeable on tires with softer sidewalls? I've gotten mixed results out of different sets of tires. On our current vehicles, two use tires with stiff sidewalls.

All measurements were from my handheld tire pressure gauge :D

My Toyo Proxes 4s aren't hard-sidewall tires in the mold of the Advan Neova AD07/AD08. Hmmm looks like sidewall construction may have a hand in this after all.

I smell a Bigbigcar writeup coming :D

i have upgraded my stock steelies to alloy rims. from 185/70/R14 to 205/50/R16. Mas ramdam ko ang road pero comfort (or lack of it) is about the same. now better at cornering and more stable at speed.

Hindi ko nasukat, pero impression ko na mas magaan ang R16 rims kaysa sa stock. Both with tires. I was looking at rota tires, ang bibigat.

[renzo_d10]

^ If you look at Concept One's sir. Napakabigat nung mga yun. :bwahaha:

[meledson]

I think, the heavier the rims, mas matagtag.

yup, still got it on my tires for three months now, from 30psi (november 2009) to 28psi (feb14, 2010)...and there is no really really really significant difference between compress air and nitrogen regarding comfort. matagtag pa din! sobra! (215/45r17) haha its low profile!


the only benefit i got on nitro on tires is that i dont need to check the pressure frequently. ihmo

its just in your mind.

sorry ot

[aejhayl17]

i disagree sir

i think, the thinner the sidewall of the tires, the lack of ability to absorb impacts, mas ramdam ang tagtag...this is what in my mind, what do you think sir mel?
