Indeed. The tyres in F1 are from old regulations. But the teams would love biggers rims. They have 13" rims now. And stil extreme brakes. But not lomh ago they tested a new rim size. I believe 18". This for better brakes and more responsive tires. The are now runnin realy low tire preasures. I believe they were around 1.2 bar. And a huge amount of suspension work is in the tire sidewall. I.m puting up 3 pics of the wheels they tested. Hope this clears someting.
