An offset of 12P means there is 12mm of positive offset. Here is a (crappy) cross section of a rim, excuse my lack of artistry. See notes below. Its supposed to be a minilite..... Take a rim with no tyre on it. Measure the distance where the tyre would normally be, from the front face (BLUE X) to the rear face (YELLOW X). Half of that measurement is the centre line (GREEN C) of the rim. 12mm offset means that, the face of the rim that presses against your brake hub (ORANGE LINE) is 12mm away from the centre line of the rim. A positive offset means that the face is 12mm closer to the rear of the rim (YELLOW X). This makes your wheel sit close to your wheel arch. The higher the number is (in the positive) the wider your wheels will appear. If it had 12mm negative offset, it would be 24mm the other way ---12mm back to the centre line, then another 12mm towards the shiny side of the rim (BLUE X). This would make the distance from the orange line to the yellow X GREATER than the distance from the organe line to the blue x. The rear edge of the rim will be closer to the suspension and subframe. Minis with a large amount of positive offset usually need to have wheel arches fitted to cover the wheels. Large amounts of positive offset will aslo put added strain on wheel bearings, because the wheels are moved AWAY from the bearing. I hope can you understand what i've said... Unfortunately i dont know the standard specs of a moke wheel, but someone else here will.....

Thanx for that man, much appreciated! The situation is this... I gotta moke, and the cars in shepp, wheels are in geelong.... cant exactly borrow them, lol, cars not on the road.... and id buy em, cept im worried bout the offset!! the wheels im currently looking at are hotwires 12" X 6 12P offset...... can anyone tell me if theyd fit a moke? I checked the offset on my std moke wheel n it was 100mm from the inside hubface to the oua (most inner edge) of the rim...... help guys! c'mon guys!... wheres the DOC lately? -Cam

No reply from the Doc??? Okay then.... You have measured the STANDARD wheel by putting a straight edge (a ruler maybe) across the back of the rim, then using a tape measure you have measured 100mm from the mounting face to the straight edge, am i right??? If the standard wheel measures 100mm here, you will want the mag wheel to measure the same. If the measurement on the Hotwire rim is a bigger number (eg: 105mm or more), chances are that the Hotwire rim will rub on the trailing arm, or shock absorber. If the measurement on the Hotwire rim is smaller (eg: 95mm or less), the rim will fit without hitting the suspension, which is a good thing. Just be careful that they don't stick out too far when fitted to the car.... I'll put a photo of this "measurement" up soon if ya want...

Okay, here's the picture (hand drawn again, sorry).... This would be the "measurement" you were talking about.... If it is 100mm on your standard moke rim, make sure it is 100mm on the Hotwire. 110mm will be a very tight fit. I'd advise the upgrade to stepped drums and extended studs in this case. 120mm will not fit, it will rub. No good. You will definately need to fit stepped drums and extended studs, but the rim and tyre will still be too close to the suspension... 90mm will fit without a worry, but might hang out of the guards, and will put extra load on your wheel bearings... I hope this is the answer you wanted....

thanx for ur help S/C.... yeah thats correct in ur second drawing, thats wot ive measured... with the offset being 12P on these hotwires.... and a 6" wide rim...culd u now say that thers a fair chance theyd fit?? coz i think a moke wheels is 5" would that be right guys??? just a stok steelie (13")?? ther going on my moke, so theyve already got the spaced drums and the extended studs...thats why i dont want there to be an issue cos short of putting spacers on... can i get longer studs? cheers.. -Cam

IF the 12P actually means 12mm positive offset, Yes they will fit. Its a 6 inch wide rim. Centre would be 3 inches (76.2mm). Now you TAKE AWAY the 12mm for the positive offset (you would ADD 12mm if it was negative offset) 76mm - 12mm = 64mm from mounting face to rear of rim. (35mm more clearance than the standard wheel.) Hmm, these wheels are going to look very wide compared to your stockies. The stockies would have 35mm NEGATIVE offset if they are 5 inches wide. According to the calculations, the hotwires will stick out 2 inches more on each side of your car.... Dont forget, a mini stud pattern is 4 x 101.3mm , not 4 x 100 4 x 100 will fit, but the nuts will be tight........ Good luck

Who is selling them? I might know him. My Moke-in-progress as 13" x 5.5" Hotwires and 185/60R13 tyres. With STANDARD (non-spaced) drums the wheels fit, clear the trailing arm by heaps, but the tyre sidewall is about 10mm from the subframe mont bolt at the back. With Mini S spacer drums they hang 1" out of the guards. Most Moke 13" spacer drums are halfway in between standard and Mini S types. So you should be okay. The longer trailing arms on a 13" wheel Moke means less clerance problems than a Mini. I will check the offset on my rims tonight and report back.

Moke 13" drums are about 19 or 20mm spacer. I got one s/h once, thought it was an S one- turned up some nice alloy spacers the same width (to fit with stock drums & replace my worn out S rear drums) then found they were 5 or 6mm too narrow... Oh well- anyhow, I sold the spacers to ausminis4u... they are going with his Honda brakes. So beware- if you are buying S/H spacer drums, check the width!!!

My Moke's Hotwires have on the outer side: 5.5JJx13 and on the hub side 2 (upside-down P) 1280. The 2 and 1280 has been cast into the wheel, the upside-down P has been stamped after casting as it is not in a consistent spot on each rim. But it is always between the 2 and 1280. Probably does not help a lot! Measured a stock steel late-60's Moke rim - 100mm from hub face to outer edge of the rim. Measured a Hotwire - exactly the same measurement. Since you have spacer drums fitted, and I don't, you should have enough clearance at the back. Get the seller to measure so you can be sure. BTW: Why do you want to go from 13" rims to 12" rims. You know it will mess up your gearing and speedo with the reduced rolling diameter? Or is that what you want?
