They also quoted XM1+ -> 4700
and Advan Neovas -> 5500

I plan to upgrade the stock tyres on my Palio 1.6

pls help

i wouldnt recommend advan neova for a palio unless you plan to do a lot of spirited highway driving or go for track days. it doesnt make sense to put up with the hard steering and stiff ride for city use. in other situations its really good. look at cpc2 or xm1

What is the size of i10? Swift's stock is 165/70/R14 and i had asked the rate for 185/60/R14 (the ZXI size)
Anyways how the performance ,any major difference in grip in curves?

i10 stock is 155/80 R13. Actually i had asked the rate of 185/60 R14 only. He said it was rs.4075 for Michelin XM1+ but LALA quoted rs. 4100 for 175/60 R14.

Joshguy, tell me if you plan to change your tyres. We can go together and bargain hard for a good deal. I plan to shift to MOMO/HRS/Lenso alloys too. So we might get a good price if we bargain.

Hello guys,

I have an Indica turbo done 48k kms. I want to upgrade the tyre as they are on end of their life span. The stock tyre is 165/65 R14 Bridgestones (steel rims).

Please suggest a good tyre which have more performance than the stock ones.

Is it possible to get a minor section upgrade on the same rim. Alloys are out of dream as am running on less budget.

Rgds.

hi,

I second Sai Iyengar in Indiranagar. Ashwin Balaji is a dear friend of mine too. I got Rs 600/- cheaper on the CPC 2 on 205/55/R16. Madhus demand 7200 as against 6600 at Sai Iyengar.

go for it, very good tyres. I recommend the Michelins though for I used to drive the Pilot Preceda 185/60/R14 on the Palio 1.2 ELX.

great set of tyres.

cheers,

[vaisakhr]

Hi Guys Need serious Help,

Since Past couple of months i am facing terrible problems with my M800 tyres, they are stock 145/70-R12-S Good year, I had replaced rear tyre tubes 5 times now and also 2 times for my spare tyre. Small puncture shops bill me 300 + labour for tube which is not original (Duelop, JIK...), I have now decided to upgrade my tyres to tubeless, but need help on deciding the right spec. GTO recommended chart says "145/70-12, 155/65-12, 165/60-12, 155/60-13, 165/55-13", now which one suits me as per my below requirements:

1. I am a spine patient and my M800 is a non-power steering vehicle, however drive is smooth now with stock tyres, but will the steering be hard if i upgrade 13 sized tyres ?

2. My Avg drive per month is ~1000km and as of now vitamin M is the issue, so i need the cheapest and good.

3. I Prefer a tyre which can increase little high on ground clearance, however if its not satisfying my above 2 requirements, this can be void

4. last but not the least, i want a tyre with max life, i dont like to keep running in to puncture shop again and again.

Please help me in deciding right tyre and also suggest me approx rates and good place in bangalore.

Thanks

I changed my Getz GLS car's tyres from 170 75 R13 to 185 65 R14... I just wanted to know what would be the deviation my car's speedometer and odometer will have because of this upsize.

I did some calculations myself.. correct me if am wrong please.

The radius of the 170 75 R13 should be

R = 6.5 inch + 5.1 inch (i.e. 170*.75/25) = 11.6 inches
So circumference is 2*pi*R = 72.85 inches.
For this tyre to travel 1km, it would make (1000*100)/(2.5*72.85) ~ 549 revolutions.

Similar calculations for 185 65 R13 would come to approx 496 revolutions.

I am assuming that my car's speedometer is calibrated to show as 1km/hr if tyre makes 549revolutions in one hour and odometer is calibrated to show as 1km extra when tyre makes 549 revolutions.

Assuming thats correct, now my car's odometer would show as 1km extra after 549 revs, but it had already finished 1km by 496 revs itself. Hence it will show a deviation of 9.6%. So when odometer actually shows 10000km, it should have shown 10960kms.. .Am I right?

And similarly... speedometer will show 80kmph when it makes 549*80 revolutions in one hour.. whereas actual speed would be 80kmph when it makes 80*496 revs in one hour... so when it says 80kmph... the actual speed is 9.6% more.. i.e. 87.6kmph! Is that right?

I am more interested in the speedometer one to make sure that I am not caught by the interceptors

I am sorry for the lenghty post and do laugh if I sound

Thanks for that, will check it out.

Now my next question would be... I have noticed that my braking is a bit weak after the tyre change. Is that just my imagination or does it have anything to do with the tyre change?

[akshay4587]

I had 175\70\R13 in my Accent,before i upgraded to 185\65\R14.
This was like 2 years ago,so i dont really remember any Mathematical calculations,that i had done at the time of purchase
However,over the period of 2years i have noticed that the speedo is extremely accurate,and sometimes it underreads even.(Verified with 2 GPS devices)
80-on speedo is like 81-82KM\hr on GPS.
100-on speedo is 100 on GPS.
So with the upgrade,you have a speedo and a Odo,with almost Nil error.

[indkish]

My actual tyre size is 175 70 R13, not 170 75 R13
I did a calculation mistake here.. took pi as 3.41 by mistake instead of 3.14 in new tyre calculation... so instead of 539 revs.. I got 496 revs

So correcting that mistake and also old tyre size mistake.. the % deviation is only 3.46%

So when my speedo shows 80kmph.. its actually 82.8kmph am going in.. which I dont think the cops would mind much..

Thanks LNK.. the link you gave also shows almost same thing. So my calculation is actually right.. hehe

Did you notice any change in braking?

When last were the brakes serviced/checked prior to the tire change?
