I have a 2015 Renault Clio and I've never been sure what size tire I should buy. I see several options at the petrol pump and I'm unsure whether I should go with what's written on the door panel or if there are other references I should check.
Don't overthink it - whatever's written on your driver's door jamb is exactly the size you need, end of story. A lot of people stand around looking at various options at the Galp pump but the truth is the manufacturer already picked the best one for your Clio and for normal driving conditions. If you really wanted to explore alternatives (like a tire that's a bit bigger or smaller), that's something more technical you'd need to check with a tire shop about, but for 99% of cases just follow what's on the door jamb and problem solved.
The driver's door jamb is indeed the right place, but here's a detail nobody mentions: if you want to get more life out of your tires, also check your owner's manual, because sometimes there's more than one option there and you can choose between slightly different sizes depending on how you use the car. Another practical hack is to write down the information on your phone before you go to the gas station, because you'll definitely get confused with all those options on the wall and end up leaving with the wrong tire.
