Tyre upsize dilemma for Ritz vdi

Hi,

I been thinking of upsizing my Ritz vdi.. and i been doing my research online for quite sometime now.
I have read couple of threads which are similar, but couldnt get any clear picture. 

There are two choices for me 185/70 R14 or 195/60 R15 (stock is 165/80/14) i will be changing to alloys.
My main concern is Fuel Efficiency. will there be drastic change in FE if i change to 195/60 R15 ? 

what will be pros & cons for both 185/70 R14 and 195/60 R15 ?

My current choices are BS ER60 / G3, Michellin xm1+

another question i have is about ABS and odo meter reading. Will ABS be affected by tyre upsize ? and i know there will be errors in odo meter reading after upsize. is it possible for us to get it calibrated to match the upsize ?

any help and suggestion is highly appreciated

lessirey, welcome to CW!

Nice to see you have done your homework well.

It is indeed a good practice to maintain your final wheel dia equal to your stock wheel dia. Your choices obey this rule.

185/70/R14 would be easier, because the tread width changes just by 20 mm. This means you tyres will be just 10 mm wider on either side of the rim. This will have less chance of fouling, or rubbing with fender inner side / inner side of the wheel wells.

The same will have to be checked more thoroughly with 195/60/R15. Extreme turned positions, loaded vehicle, inclines, forward and reverse movement are some of the parameters you need to check against by varying one at a time.

ABS is not affected by the upsizing. Odo/speedo is only slightly affected, no particular remedy is necessary. FE will be affected because the tyres will provide more rolling resistance. The decrease will be ~1kmpl or less. You tell us how much it was exactly after upgrade.

Tyres I would recommend XM1+. Good for FE, longevity.

Update us on how the upgrade goes.

Thanks for the helping hand and warm welcome

i may have a couple weeks time to make the final decision.

My driving style is kind of harsh (but not crazy) .. i mean, i used to take sharp cornering and precise maneuvering with my Santro (with upsized G3 wheels) and was happy with how my ride stays in my hand. But with Ritz i have to compromise a lot on that, due to the tall boy design the body rolling is high with the stock tyres. My santro also had lil body rolling on sharp cornering before i upsized.

So my intention is to be on the safer side, I understand 185/70/R14 is a safe bet.. but will it help with killing the body rolling of Ritz ?

I understand there will be little drop in FE when we upsize, but is the drop higher with 195/60/R15 than 185/70/R14 ? or are they kind of same to same ?  thats one thing which i couldn't yet make up my mind in my research

Regarding tyres.. i was confused if i should go with XM1+ or ER60, the only reason why i move lil bit away from XM1+ is regarding its cornering ability, G3 was sharp in cornering with my experience in santro. any suggestion regarding that ? and any idea how appolo acelere perform ?

For your driving style, i guess the Yokohamas S series would be a good fit.

As you are running a diesel car the drop in FE would be of academic interest rather than of practical importance.

Avoid the Apollo.

I like the way you said it, but i would like to know what you really meant did you mean it like its negligible ?

Yoko S drives, hmm.. i've had them in my list once, dont remember why i removed it, i'll do a detailed study on that. and yeah Apollos are out ;)

lessirey, i have yoko A drives on my carb zen and trust me its fun to drive. I too am a harsh (but not crazy) types and its damn stable at high speeds and sharp turns. The noise levels too are at almost next to NONE !

i see, thats interesting to hear vIcKy..  I'll look for more details on Yoko.

Lessirey, I said safe from the POV of fouling with the wheel well and fenders. With 195, it would be 15 mm of extra tyre on each side, provided you maintain offset just the same with the alloys.

FE will be slightly less with wider tyres, wider the tyres, more the impact. But in total it should be about a kmpl of so. Should not bother you.

I kinda understood what you meant, but with 195 will i have to compromise on driving comfort ?

195  tyres with 60 profile would be a bit harsh on our roads, there would be more tram-lining and ride quality would come down and steering effort would go up.

195's might also have some implications on warranty.
