I don't recommend *skinny* tyres on a 'fat' rim, stick within the tyre makers guidelines for what size tyre fits what size rims. Offset is the distance between the centre line of the wheel and the hub mounting face, not the backspace. You need to get backspace out of your mind completely, even though you measure it to get the offset dimension. And, I owe you 1000 apologies, I have got it backwards, as I was thinking about wider rims on a standard size axle, not rims on a wider axle. Jeeze, sorry mate, I can see why you are confused ! OK, so now, when you increase the offset by say 20mm to 40mm, you are moving the hub mounting face (up) away from the centre line of the wheel, and moving away means moving the rim inwards, towards the diff. Trying drawing a cross section sketch at a relative scale to see what it looks like from behind the car (say). And always remember that your RA28 track is 1310mm, the offset is 32mm and the hub to hub is 1374mm. If you are using any wider axle, say hub to hub of 1410mm, that is an increase of 36mm over standard (18mm each side). To get back close to the original track of 1310mm, you will needs rims with an offset of 50mm. 32mm plus 18mm. So, you are right mate, you're not going crazy ! If you can only get 7 inch rims with a 40mm offset you will end up increasing your track by a total of 20mm (10mm x 2) but that is still inside the legal limit. Now I just wish I can edit my earlier posts a swap a few words around. Mitch. [Updated on: Mon, 03 May 2004 06:34] [Report message to a moderator]
