I have a few short and pretty stupid questions, which Google could not really answer after a long search…I’m totally layer The specialists here can answer this right away. It’s a Corsa C Bj.02 (1.0), on which previously 175 65 R14 tyres were on it. For the Corsa C (1.0) there is the 5Jx13 steel rim and the 5.5Jx14 steel rim, is that so far correct? My real question is: Is it theoretically possible that it is a 5Jx13 stah I don’t know. My question is that it’s not possible at all, so for the “tire assembler” (workshop) who pulls the tires onto the rim it’s sunny clear or can he also overlook what and put the 14″ tires on a 13″ rim without seeing anything big? And another small question…do I have a chance to see which dimens in a mounted condition? is it the 5Jx13 or the 5.5Jx14? Possibly by measuring if I remove the wheel caps?
