Diameter should still be same isnt it?
The change should be the surface area
🤔
Keep in mind that when you go wider, most tires become taller unless you go with a smaller aspect ratio. The aspect ratio of a tire is the middle number in the size. This is a percentage of height based on the width. If you are considering the tire size mentioned previously, the height of the sidewall is 65% as high as the tire is wide. This means that if you want to go wider you should also go to a smaller aspect ratio like 60%. This will assist in making sure that the overall tire diameter remains close to the same. By doing this you refrain from affecting things like speedometer calibrations and transmission shift points.
That's why if there's a change in the specs, be it increase/decrease in width/height/rim size, it always inevitably have to be deducted tp keep it balanced. Thus there won't be much diff if the change is from 175/65/15 (default, comfy/squishy ride) to 185/60/15 (slightly more road feel) or even 195/55/15 (less fuel efficient and but road feel is more planted). See, you increase 1 part, you'll inevitably have to decrease another part.
LA773 Oops. Terhijack your tered. Anyway, 195/55/R15 is always cheaper cos more demand. Forgo a slightly worst fc but better feel. It will decrease 20mm off your car height too. I personally use Goodyear Triplemax 2 because price in EM is also mcm haram like Penang due to logistical charges. Albeit, a good tyre but of cos not PS3 good. That one cost 380/tyre here.
