    HI all, My car is a gen 1 and was delivered with 18/19 set of wheels
    Sticker on driver door says 2.2 bars allround for those original wheels
    Previous owner converted the car to 20 inch challenge, but I have not found at what pressure tires should be inflated
    I know Jeremy has 2.4 front and 2.2 back on his 19 split rims
    Would anyone with an OTO would know ?

    That's what I'm running with MPSS, feels about right. I think having the higher pressure in the front is key.
