Default Tyre upsize for Indica Turbo V2

Hi

My car is currently wearing the stock Bridgestone S322's (165/65/R14)

Want to upsize to a wider tubeless tyre. How wide can i go without hurting the car dynamics....is the 195/70R14 95H Potenza RE88 ok...
please advice.

Please read http://www.chris-longhurst.com/carbi...yre_bible.html
this has an upsize calculator... BTW..the upsize you have mentioned is wrong and will give you severe speedo error

You will have to reduce the wheel dia to 13 and you may have to keep the same profile or less if you really want to increase the width that much. (use the Tyre size calculator in the web listed in the above post to minimize the circumference difference)
As an owner of indica i never suggest decreasing the profile. Most of the indica owners suffer from tyre issues. Being heavier in the class, running with low profile in rough roads punishes the tyre hard.
Mine, on alloys, 2 tyres have been already torn.
I'm not sure if Tubeless are more resistant to rough roads and sharp edges of potholes.

Are u upsizing the tyres on the stock rims???? Or u are going for new alloys???
The best upsize is 185/60-14 GIII rubber but it is advisable on alloys not stock steel rims

Hey thanks,

Oh yeah, forgot to mention.........i had put on the Tata 6 spoke alloys on delivery infact.

But as per the carbible calculator 195/55 R 14. seems to be the best option without any odo errors!!!

please check with your mechanic about whether 195 will brush the insides. i feel 185 is optimum for indica. 195 might look extreme, unless thats what you want.

Dont think 195/55-14 will touch but any tyre with below 60 profile is not ideally suited for Indian roads.....

I'm having 65 profile tyres on my zen n the ride quality isnn't to my liking...

185/60/R14. This grips a 110bhp Palio 1.6 well.
This upsize is more than enough for a 70bhp Indica turbo. Dont go overboard,bro.

kpzen, the profile figures are dependant on the tyre width, so you cannot compare 65 profile on a 175/65 to 60 on a 195/60. or are you saying that you have 195/65/14 tyres in your zen ?

Anyways isn't it gonna be the distance from the rim to outside of the tire?
I'm warning you.. Dont reduce the profile too much.. I have an indica and i know how severe its gonna be (anyway if you drive only on 'perfect' roads, pls ignore). Please read my above reply to this thread.

Ya u are right n i know this....but the the profile n width are related..one increases n other decreases...


195/65-14 on my zen.... impossible .....

195/45-14 is possible n a few tbhpians are having those...

My zen has 165/65-13..

go for the 185/60 R14 upsize..
its an ideal upsize and provides good grip and lowering the profile anymore would hurt the ride quality,,
i have been using the 185/60 R13 on my indica .. there is good improvement in the grip and steering feel than that provided by the stock tyres..

Can anyone using 185/60 on indica turbo inform me regarding their experience in respect of any side walls brushing the suspensions & the type of wheels used & its offset.
