I am surprised that the rolling diameter difference has not seriously been discussed here & the resultant effect on engine rpm & speedometer/odo error.

185/60 15 = 60% of 185 = 111.00 mm effective dynamic radius

195/60 15 = 60% of 195 = 117.00 mm effective dynamic radius

205/55 15 = 55% of 205 = 112.75 mm effective dynamic radius
Yes this is an issue I've noticed after upgrading from 185/60R15 to 195/60R15. Although 2% extra diameter is generally accepted, it caused a very noticeable shift in gear ratios.

All the gears have become taller and there is noticeable reduction in torque because of the larger diameter of wheels. The ride quality improved thanks to the extra sidewall cushioning along with slight increase in ground clearance ( which is good in bad roads but again causes a bit more body roll)

I suggest you to change to 205/55R15 if you value performance and handling. Very little tire choices though but atleast you get the Continental MC5

Sorry, my post was incomplete. I sent half of it by mistake while typing, then went to edit & exceeded the time limit.

The complete post is below:


I have a December 2018 Vento 1.5 TDI with 13,500 kms on the odo & stock Goodyear 185/60 15 tyres on OEM alloys.

I am surprised that the rolling diameter difference has not seriously been discussed here & the resultant effect on engine rpm & speedometer/odo error.

1) 185/60 15 = 60% of 185 = 111.00 mm effective dynamic radius

2) 195/60 15 = 60% of 195 = 117.00 mm effective dynamic radius

3) 205/55 15 = 55% of 205 = 112.75 mm effective dynamic radius

Circumferences in inches (rounded off to nearest whole number) in the above 3 cases would be:

c1 (stock) = 27 inches
c2 (195/60) = 29 inches
c3 (205/55) = 28 inches

The 205/55 upgrade will therefore be closer in maintaining stock rpm at a given road speed & the odo error will be less.

The following will be the odo error with the 2 upgrade sizes:

For 195/60: At a speedo reading of 100 kmph, the actual speed will be 102 kmph

For 205/55: At a speedo reading of 100 kmph, the actual speed will be 101 kmph. Thus a lower speedo/odo error compared to 195/60.

Considering that those here who have upgraded to 205/55 15 have never faced any issue of tyres scraping wheel wells & have notice a considerable improvement in grip, handling & comfort has not been compromised, wouldn't 205/55 15 be a better upgrade size?

I would appreciate it if those interested in this topic can share their thoughts on this since I would like to replace the OEM Goodyears very soon.

Thanks & regards,

Prithvi

Planning to get Yokohama S.Drives in 195/55/R16 (stock size) for my incoming vento.

Ashoka Wheels (auth. dealer for Yokohama here in Hyderabad) offered a buyback price of 4200/- per tyre, while the S.Drives retail for around 7100/- per tyre.

Is the buyback price fine? Will have driven for less than 20 km overall from the time I take delivery to the time I get to the tyre shop.

Any S.Drive owners want to vouch for the wet grip of the tyres?

Any specific reason you want to go with the S Drives?

Didn't know S drives are still on offer. That tire was designed atleast a decade ago.

Today's tires offer a package of performance, comfort and noise control far better than 10 years ago! I would suggest you to try Continental MC5 which may not be as sharp a performer as the S Drives but will give you a far more balanced gain especially comfort and silence.

If you want a more rugged tire, do consider the MRF Perfinza too. Done 10k kms with it and it's a blast. Holds on like a leech. Exceptional aquaplaning resistance. I doubt if it's available in 195/55/R16

Michelin Primacy 4 is almost impossible to source thanks to the tire ban!

Sure, this is on my list now, I definitely heard of em', but was looking for a mix of performance and road noise reduction, leaning towards the former for sure. But since the car'll be new..might take you up on this suggestion!

Yeah, not available in 195/55/R16. Thanks for the suggestion though.

Annoying decision by the government, but nothing we can do about it. An authorized dealer estimated about 1-2 months before the Michelin situation is resolved, so it's out.

I know this reply might be late. That's absolutely right - I have been using 205/55/R15 Conti MC5s for the past 1 lakh kms on my Vento and they have performed beautifully. Superbly grippy at high speeds and very confidence inspiring.

On a different note, I am looking to replace my OEM 15" alloys with some neat aftermarket 16 inchers. Can anybody recommend comfort oriented tyres available in the 205/50 R16 size? I am unable to find Contis MC5/UC6 for this size due to stock shortages and dealers are suggesting to upsize to 205/55 R16. This adds a centimetre of ground clearance and I am not sure how my riding experience will be.

- Will the increased GC of 1cm affect handling at high speeds?
- Has anybody installed this size on their Vento/Polo?
- If yes, any wheel well issues?

I am using Hankook Ventus V2 of size 205/50/R16, i have had no issues with the tire, though I definitely think that road noise is a bit higher on these. Option that you can also look at is Michelin PS4, I did not buy them as i plan to switch car by end of this year and new tires were needed only for 2 years, so did not want to invest lot of money.

you can check pic of the tire here. (My modified VW Vento TSI - From Brownie to Mark 13)

I got Yokohama Earth tyres on my Vento. Feels good and its noticeable compared to my previous Bridgestone AR20.
Heard there is shortage in supply for various brands. Luckily one of the shops had them in stock.

Thanks for sharing. Michelin PS4 is out of stock for many sizes due to the import ban.

Yes, Yoko Earth-1 is available though it looks like it is also going quickly out of stock. Blue Earth is hard to get though!

Here are my options currently based on my calls with dealers nearby and available stocks:

- Conti UC6 205/55/16
- Conti UC6 195/55/16
- Yoko Earth-1 205/50/16
- Yoko Earth-1 195/55/16
- Yoko Blue Earth 205/55/16

My preference is 205/50/16 - still waiting to see if there are more options.

Upgraded to Continental UC6 195/60/R15 from stock Apollo's.

Have a 2013 Vento 1.6 petrol highline AT; with the speedo at 58116Kms and last 2 Apollos were close to finished with very little grip.

Before the lockdown had to replace front two tyres in emergency and the shop had basically sold the driver old 2017 stock JK UX Royale 175/65 R15... basically downgraded the tyres with their spare stock. And since the driver had to get it done in a jiffy, no invoice was given as well.

Thankfully the car has not run much during the lockdown apart from weekly grocery runs. Now that I got a chance, I tried to source the Michelin P4 ST, but with no luck on getting them, took a chance with Conti's UC6 as it has good reviews so far.

Have a trip to Pune coming up this weekend and will be able to add a little more about the experience. But so far the tyre seems far more silent.
