F100 rim offset

[steve125]

Is there a 'standard' offset for F100 rims? I have found some 15x8 sunraysia rims for sale but the seller can't tell me what offset they are (I believe it needs to be around -25mm).

I want to fit 31x10.5 tyres to my WT Sierra (after the body lift) and the recommended rim for these tyres is between 7" and 9" so a 15x8 should be OK. However, reading Outerlimits, some were saying that 8" is too wide for a 10.5 (it will roll off the bead easier), then someone else will say 7" is too narrow. Who's right?

I use f100 rims, but mine are offset modified to suit a narrow track.
They are 8" rims and I've never rolled a 31"tyre off them yet.
I think 7's would be better, too, but 8's seem easier to get, and then you have options to go bigger tyres one day if needed.

I used 15x8s with 31" silverstone extremes for a while and never had a problem except I did dint one rim a little on a rock...I could run them at 4-6psi with no problems.
