Honda Amaze VX i-DTEC Ownership Review

So you changed the stock tires that are of size 175/65 R14 to 185/65/R14 ??
And that increased the ground clearance from 165mm to 172mm??
172mm is quite acceptable and I would be happy with that.
What's your tire pressure set to?

How can we validate the increase in the ground clearance?

The reason I am asking this question is: A month ago I had a chat with the Nissan staff to find out how I could potentially increase the ground clearance of Nissan Micra by upgrading the tires and he didn't think changing tires would really help the ground clearance. Honestly I was not convinced with the answer but I left it at that. Perhaps this thread would help me gain a deeper understanding of upgrading tires in order to increase ground clearance.

I changed the tyre size to 185/65/R14 . 185 is the section width of the tyre. 65 percent of 185 is the height of side wall i.e 185 x 65% (or simply 185 x 0.65)=120.25 mm
stock tyre were 175 x 0.65=113.75 mm
so the increase in side wall is 120.25-113.75=6.5 mm
and increase in side wall is increase in ground clearance

Only neglibible increase will be there.

it may be a negligible increase but in terms of cars few mm makes a big difference.

I exchanged them for new yokohama tyre. I sold them for Rs 3300 each and bought the new one for Rs 4500 per tyre. I only had to pay the difference amount. 1200 per tyre
