I've got a 2003 Ford Focus which the previous owner fitted with go- faster alloys, despite it being a 1.6LX. It needs new tyres all round so I thought it might be cheaper to get some second-hand wheels of a more sensible size instead of having to fit wide low-profile tyres. Rather than restrict my eBay search to Ford Focus wheels I thought I might try a more generic search to get more buying options. The tyre size for the base model is 185-65R14. I found a site which explained how to calculate the best tyre size for a rim's "J", and working backwards got 6J. The car has 4 studs and another eBay item I found was
so I guess I need 12mmx1.5, but I don't know about the length. But eBay will only let me search for stud diameters from 98 to 114 unspecified units. Presumably the diameter of an imaginary circle passing through the centres of the studs? Anyone know the right value for a Focus?
There are 4 studs per wheel BTW, but if I tick that on eBay I still get loads of results with 5 anyway.
