Hi... I am looking to get new wheels for my 2007 Copen. Can anyone give me the original wheel sizes and also what's the maximum wheel size I could put on?
Depends on what your local car roadworthyness testing facility is willing to accept You can put almost any kind of tire on there, but you might have to invest in wheel spacers, broader wheel arches, spring rate reducers (if that is the correct term?) etc. I think I have seen 6.5x15, but I know there is a document somewhere here that shows every possible combination and the work you have to put in in order to get through MOT/TÜV
It's MOT not TUV Salieri, our tests don't care about approvals, you can literally just slap anything that fits on and if it drives to the MOT station without them falling off, they're fine. Dezent Ti 5jx15, 4x100pcd, 45 offset on Uniroyal Rainsport 3 195/45/R15 with kerbing rib are what I switched to, I've attached a pdf of wheel sizes used by our German friends but they're a lot more restricted than we are. Mine needed no work doing, no rubbing and handling is fine.
Hi I've gone for Dezent Ti too. Recommended by local garage and a clear easy fit. Having them fitted this afternoon! Yeeiii!
Dear Copen Riders, I am considering increasing the aspect ratio of the tire to 165/60R15 instead of the OEM size 165/50R15. This change should provide a more comfortable ride, especially on bumpy roads. Has anyone tried this? Thanks, everyone.
I did switch mine to 165/65R14, which involved getting new (to me) hubs too. It did make for a better ride, most of my teeth fillings remain, but it's somewhat subjective. For what it's worth, it did increase the wheel circumference a little but judging by the Sat Nav's (GPS) speed indicator, the car's speedometer still over estimates, though less so that before. I guess all tyres don't provide the same ride smoothness either - mine are the snappily named Toyo NanoEnery 3 Premium Eco For completeness, although mine was a somewhat large increase to the tyre sidewall (c.25mm) , I never found any difference to the handling - especially at the limit but mainly because I avoid that sort of thing.
I used this website for a comparison between 165/60R15 and the OEM size 165/50R15: Rim & Tire Size Calculator. Custom Offsets It turns out the speed increases as expected, while the speedometer shows a lower speed. To compensate, I need to make sure to stay around 5 mph below what the speedometer indicates. The only disadvantage shown is a change in the negative scrub radius (about -6 mm). I'm not sure how this will affect real-life driving.
