They have best offset you can normally get anyway GN (i.e. wheels stick out 10mm from centre on both sides) , so you should be right.
Certainly ok on 80 series.

Measure the backspacing of your ROH rims. If its around 105mm, your rims will fit the 80series fine.

60series and 47series normally have about 80mm backspacing, and 80series about 115mm.

Hi Phil
Currently running these rims on 60 seris and they seem fine, so if 80 seris has more space then should be good i guess?

Not sure what you mean on the measure back space?

Do i measure perpindicular from the inner section of the rime where the bolt holes are out to the the inner edge of the rim?Regards GN

Yep, your only problem is that they may stick out too far, but a backspace measurement will answer that.

The easiest way to measure backspace is to lay the wheel face down onto the ground so the backside of the wheel is facing up. Take a straight edge and lay it diagonally across the inboard flange of the wheel. Take a tape measure and measure the distance from where the straight edge contacts the inboard flange to the hub mounting pad of the wheel.

Cheers

Put your wheels outside down and put a flat object across the rim and measure down to the centre where the stud holes are.

If you clean around the inner rim there is usually the settings of the rim with figures like TOPY and a set of numbers that tell you what is what It is stamped into the metal and can be hard to see unless the rim is clean.
