Hi everyone, I'm new in changing rims and tyres, and I need some professional advices before wasting money on a wrong tyre.

I'm now driving New Myvi 2018 1.5H, according to the official data from internet, my original rims are 15inch 6JJ, and I recently bought a 1set of 2nd hand 15inch 7JJ ET30 rims from a friend, and still using the original tyre which is 185/55R15.

But a lot of friend said that my original tyre doesn't look very match with my new rims (15inch 7JJ ET30), so what tyre sizes is the best match with my new rims?

Yeah, a little bit
