ROH 14' Alloys - wheel nut seat angle

[CMF_gocart]

Hi Guys,

Finally tracked down a set of 14" alloys (ROH Reflex 14"). PCD = 4 x 100mm. Anyone help me out with some info please?:

1) Is the wheel nut (M12 x 1.25mm) seat angle 60 degrees? Any suggestions of where to get a good set?
2) Anyone know the offset?
3) Would you go for 165x60x14 or 175x60x14 tyres?

I've ordered a set of 63.3 x 59.1 mm hubcentric rings from a website in Finland - hope they fit OK!

Thanks very much.

Hey gocart

Just my thoughts:

1) From my experience, the seat angle for nuts are typically 60 degrees. Found this:

"SEAT TYPE: There are three main wheel nut / wheel bolt seating types, 60 Degrees Taper Cone, Radius Seat or Flat Seat. In the diagram below you can see these different bolts seating types. The correct nut / bolt seating type is required to ensure that the new nut or bolt seats correctly in your alloy wheel." from http://www.performancealloys.com/wheel-nuts-wheel-bolts.aspx.

Please get steel ones, not the 'lightweight' alloy ones that you see around

2) if the wheels are designed for FWD cars, the offset will be either 40 or 45.

3) Personally go for the widest in easily obtainable size (cheapest).

Hope that helps
Chris

Thanks very much Chris - very helpful.

I'll track down some steel 60 degree tapers - I can eliminate sphere and flat seating from looking at the seat.

Cheers
