Hi All, New to Copen ownership, recently acquired a pearl white 659cc 2005 Copen here in the UK, original UK car so was undersealed from new. I've just bought some 15x6.5j +45 alloy wheels but cannot for the life of me find the optimal tyre size to not rub the arches of the Copen, can anyone help? I'm guessing it'll be either a 175/50/15 or a 175/55/15? Many thanks in advance! Nick.
The standard size from factory is 165/50 R15 73V. And the original tire used was Bridgestone Potenza RE040 You can't get those tires anymore (I bought the last 2 I could find online) and there aren't many choices in that size in europe unfortunately. I wouldn't get a xxx/55 tire because the total wheel diameter will be different and that will make the speedo read wrong. I think a 175 width tire will be good for clearance, but I don't know as I haven't tried. oh and theres this cool website for seeing tire sizes: Daihatsu Copen 2005 - Wheel & Tire Sizes, PCD, Offset and Rims specs
thanks for the reply Afron1! my speedo would read 5.7% too slow with a 175/55/R15 not the end of the world but I think you're right, I'll stick with 50. Cheers!
