Can we put tyre of size 155/80 R13 for santro xing ?
The stock size for Santro Xing is 155/70 R13. Going for 155/80 R13 tyre size would not be recommended as it is an invalid upsize.
For any upsize to be valid, the diameter difference between the new and old size should be less than or equal to 3%. But in case of 155/70 and 155/80, this difference is 5.67%. Hence, I would seriously recommend you to use tyres in stock size of 155/70 R13 for your Santro Xing.

Take a look at the MRF ZVTS. These are hard compound rubber but last a long time.
If you don't drive much, then spending a little more on a set of Falken Sincera will give you better grip and less road noise. The difference will be noticeable instantly compared to the MRF at the cost of a shorter life.
