i am not sure about the profile he is going to go for,anyway thanks Mr.Icewise for the quick reply.
No worries. You can ask him to check the offset value before purchasing the rim (it is mentioned clearly) and also check the current rim's offset from his manual (or rim itself). The difference should not be more than 5-7mm, that's it. [:)]

Maruti Swift issues...

Hello people,

It's been 6 months since we purchased our new Maruti Suzuki Swift Zxi. I have been wanting to write an ownership review but couldn't find time.Shall definitely write it very shortly!. I shall be giving my car to the 2nd service this week, had some issues and niggles as usual.It would be great if you guys could help me out.

Issues:
1.Co-passenger's window pane makes loose sounds when slightly open on the move and also when the door is closed.How common is this?

2.I feel the idle RPM is a bit on the lower side.There's a slight vibration when the car is moved from standstill.Can the idle RPM be increased?

3.I can feel the clutch vibrations when i keep my leg on it.I can also feel the vibrations when my leg is kept on the brake pedal.

4.The engine doesn't rev past 4000 RPM in 5th gear even when the accelerator pedal is floored.And even the car struggles to move past 140km/h. Is it common or is it because the Maruti guys would have deliberately limit the revs until 2nd/3rd service?

5.The steering doesn't roll back to the dead center position at certain low speeds(say 20-30km/h) until i manually turn.

6.The hatch door needs to be closed with quite a lot of force.The service guy said this is common for the Zxi models as it's operated electronically!

4.It means that the speed is locked ,after warranty you can ask the service centre guys to unlock by ECU tuning and top speed 160-170 cn be achieved in 6.5 rpm.
5.Its normal,swift steering is not self centering at low as well as high speeds.
6.Operated electronically[surprise], i don't think so, i do admit its bit hard to close doors ,try greasing the door latches.

Thanks a lot for the reply VISHNUCARCRAZY.
Are the speeds locked in all the new swifts, if yes any idea of when would it be unlocked.(meaning 2nd,3rd service...).

Actually in all cars in factory standard conditions the speed is locked (Info via source at Hyundai ASS ).
If unlocked it will affect warranty ,so i would advise you to do it after the standard warranty period at ASS only,i had clocked top speed at 7500 km ODO- 135 kmph,couldn't go beyond that as road wasn't good.
I am pretty sure it can go well above 150kmph.
The stable speed is 120-130,beyond that ride starts to shiver up.
RPM at 120 kmph- 3.5 krpm
RPM at 130 kmph- above 4 k rpm

Hi. My friend also has a Zxi and I get to drive it quite often.

1. Yes. It is common in both the front windows. If you leave then halfway open, then they do vibrate and make some noise on bad (not that bad) roads.

2. What is the idle RPM? Try leaving your foot off the clutch a bit more easily (slowly) and see if it still vibrates. The car should not judder when accelerator input is given when moving from standstill. If you are a new driver, the problem will disappear as you clock more distance and gain experience. Idle RPM can be increased at the ASS.

3. No. I didn't feel anything on the pedals. How are the overall vibrations at idle in the car? It might vibrate a bit more if the idle RPM is too low.

4. I haven't tried such speed and neither is it advisable. There is no RPM limited till 7k (or 6800) and the speed lock, if there, can be removed by fiddling with the ECU. It is not a good idea anyway, as you won't touch those speeds very often.

5. No it doesn't. It will roll back but not exactly at the center position.

6. Yes boot door requires some effort. It is an electromagnetic lock (button) and not electric release ([lol]). Putting too much effort can damage the lock, and also pressing the button many times at short intervals or trying to close the boot (in a second attempt) within 10 seconds can do damage. So be careful and easy on the boot door.

Idle rpm for the Swift petrol should be around 800 in idle after the initial startup surge. If you hold it in idle, the car will drop to 720rpm slowly with sudden drops velow 700 rpm where the car judders suddenly and comes back over 700rpm

In the petrol car you shouldnt have any clutch pedal vibrations. Get that checked

You will never get past 4000rpm in 5th but you can do this in lower gears. See, gears are ratioed to keep the car in the best torque band. In 5th, its assumed thst you will be cruising at over 2000 rpm. Cruising means driving at a high speed with constant pedal pressure. So high rpms (usually used in accelerating) are not required. so the rpm restrictions
If you have ever driven the car at high speeds with the MID in FE indicating mode, you will see the best FE at between 80 to 90 kmph. Thats the speed this car is optimised for. The car is unstable at higher than 120kmph speeds, i would suggest you dont drive that fast

The centering spring rate is low in the Swift. Its a drivers' car. Meaning you point it where you want to go and it goes there. The centering rate is more in cars oriented towards comfort


The boot requires some effort to close. I think is because it uses thick gaskets to dampen vibrations between hatch & frame. But like ice said, be careful with it

Guys. Just one question - how to make the ride in the swift vxi more soft & comfortable? Already using 32psi front & 30psi back

Downsizing. You can even opt for 13" rims and a tyre with bigger sidewall can fit there, which would allow more flex and comfort. Also try what I have suggested via PM.

EDIT - Just checked that 175/80R13 would be good downsize. Bridgestone and MRF have tyres in this size. You can also try changing the suspension, and moving back to stock width steel rims.

My analysis is that the wider tyres increased contact patch compensates for the smaller side wall. Thats why the zxi's wider tyres & narrower sidewalls offer the same ride quality as the vxi
Changing springs would void the warranty but lower tyre pressures wouldnt, hence went down to 30 psi in rear. But this doesnt help with the car letting the occupants feel every unevenness in the road

No mate. Your analysis is not totally correct. Wider tyre does not have any relation with comfort, it is linked to handling. The sidewall matters and if it gets narrower, comfort is sacrificed and if it is wider, the ride becomes more absorbent. And Zxi has 185/65 on 15" rims and rides noticeably harsher on bad roads (worse than Vxi). This is because of the presence of wider rim and thus thinner sidewall.

You would have noticed that SUVs ride very pleasant on bad roads, many bumps go unnoticed and it absorbs the undulations very well. This is because of the wider sidewall (as is visually seen) and thus more flex in the sidewall (instead of transferring to the car). They have 16" wheels for this reason only, else they can easily take 20/22"s. Bottomline, Swift is not the car for utmost comfort and you can do very little to get your desired ride quality. Do comment on what you felt before the alloy upgrade? Was the ride harsh from the factory itself?

Hmm...

I can't underside. That would also make my alloy rims useless. My tyres are already Bridgestone s series. What else can i do? And why does the car suddenly go soft & compliant the go back to rough?

That is just your imagination/thinking (couldn't find the perfect word, pardon my poor English). The car will remain the same, you may have felt this because of other factors like road condition, tyre temperature, etc..

You want to keep your alloys, so you will have to change the tyres. Go for XM2s, but changing tyre is a costly bet as you will see the result only after paying the amount for the tyres. I don't think you can do much in this case except lowerimg tyre pressures. What is the amount you are thinking of to sort this problem?

My swift is ZXI variant- thereby its having 185/R15 profile.

Company recommends 29 PSI for all tyres,though i inflate nitrogen - all tyres 32 PSI.
I feel comfortable at this pressure,a 33-34 also makes the ride bit bumpy.
