Good day, I am currently driving an 8Jx19 VA and 8.5Jx19 HA with 225/40/R19 and 255/35/R19 on my Stinger GT in 2021. My new rims are 9Jx20 for both axles. The HA with 255/30/R20 is not a problem from the deviation, but I ordered for the VA 225/35/R20 tyres and read afterwards that the tire must be at least 235mm wide for a 9inch rim… In addition, I have a circumferential deviation of +0.4% and with it the worry that possibly the four wheel or other electronics, by original ET VA is 34 and HA 46.5. Here I went to VA 23 and HA 35 so that it can get out about 1cm further. I’m not sure how the rim width of 8 and 8.5 on 9″ affects with respect to the ET (according to my understanding this has no effect on the distance from wheel hub to external edge). If someone can tell me his knowledge and can possibly take my care that I have to send everything back at the end of the day. , let me know. Greetings Timo
