I want to upgrade my tyre size from 235/55R18 to 235/60R18 Michelin Latitude Sport 3

 

Is it worth to upgrade the size & How is the performance of the Michelin Latitude Sport 3

 

I don't think changing just the profile is OK, because it makes the tyre diameter and therefore rolling radius wrong. It will affect the speedo and wheel clearances.

Why?

 

In what way would that be an “upgrade”?

 

Serious question, not simply throwing cold water on your idea.

 

As above, check the numbers.

This will give an idea of the look, and difference in circumference.

If you need more clearance on the roads in India maybe best do a suspension lift.

If you want a deeper profile tyre, then the 235/60R17 has nearly the same diameter as the 235/55R18 and so would not affect your speedometer and odometer. But you would of course need new 17 inch wheels as well!

The increase in diameter is really only going to have the Speedo being accurate. 

As it is it tells that the vehicle is going faster than it is.

Maybe in India that is not important.  As to the gearing, really the difference is between Ooo & Ahaaa, or not worth bothering about. IMO.

The approved tyre size for 17s is 215/65 17.

From the Indian Skoda company for my kodiaq I had received the size is 235/55 R18, The Reason of upgrading the size to 235/60 R18, In India Road Conditions are very worst, we got lot of Potholes & Speed breaker everywhere.

 

Due this condition I want to upgrade.

If you want to change to 60 or 65 tyres, then should be looking to change the wheel rims to 17 inch

Alternatively, if your roads are poor, or stony, you may need heavy duty or reinforced tyres.  

 

Your solution will depend on what sort of speeds you need, if you need to do 200km/h (125mph) then some tyres aren't suitable

However if you do not expect to exceed 100km/h (62mph) then a more rugged tyre would be suitable

 

I increased the tyre profile on my Superb by 5% on 17" alloys for increased pot hole resistance.

 

The speedo now exactly matches the GPS on my phone...

 

 

225/60 R18 or similar would be better than 235/60. GPS speed will remain more or less and ball bearings also.

There is also the insurance issue “ has the vehicle been modified” sorry to pour water on this but if you are involved in a serious accident where investigations take place, you might have problems.

That might be different in India.

 

Maybe the OP could tell me, if you call the insurers in India do you get put through to a call centre in the UK?

You make a very big assumption that a) that clause includes wheel/tyre sizes (I’ve seen policies where it does and where it doesn’t), and b) the OP wasn’t intending to inform their insurance company.

 

And as Skoffski says, the rules could very much be different in India.

I am not assuming anything, insurance does not state tyre sizes but they do ask at the proposal stage has the vehicle been modified. If you then change the wheels and tryres to some that are not as is came out of the factory (except recommended winter wheels) then your insurance may be void. It was a general comment and not country specific. If you wish to void your insurance then please carry on.
