Buggy Wheel offsets.. and backspacing..


Hi Guys, had my engineer around today to talk seatbelts mounts and what not and the topic of tyre and wheels sizes came up, so he basically said I can run up to 1.3 x the standard wheel width, 165x1.3=215 by whatever height I want, BUT the wheel track must not be over one inch wider than standard. Which would be OK as I quite like the tall skinny tyre look,
So looking around at the wheel options I can't really seem to find anything that specifies keeping the same Offset, as many keep the same Backspacing but this will change my track too much.. :no:
Should I just go to my local wheel place armed with a degree and a tape measure and just get some made up?? Cheers for any advice. :tu:




It will all be OK in the end, if it's not OK it's not the end!

WOW! What a minefield! :lol:

Here is what I know, it might help hopefully.

I have 4 sets of wheels/tyres with different offsets and widths, and this is how they sit on a '73 Super (the front of these things have very little room, the beam Bugs have an extra 1/2" inwards).

14 x 6" mags, ET13 (3.5" in/2.5" out). With 195/50R15 tyres they stick outside the guard lip front and rear by about 30mm.
15 x 4.5" stockers, ET35. With 165/80R15 stock tyres they sit inside the guard lip by about 15mm to 25mm.
15 x 5.5" steelies, ET36. Front has 165/80R15, and is dead-flush with the guard lip, rear has 185/80R15 and is the same, dead-flush.
15 x 6" steelies, ET45. Front with 185/60R15 sits a couple of mm outside the front lip (and clears the modded strut by 2mm just!), and the rear with 206/60R15 sits the same.

Thanks for that mate, space under the guard isn't a issue as the manxter has really wide guards anyway. Thinking I will just get some made up so they meet the engineers requirements. I can't see the wheels when I'm in the drivers seat anyway! Cheers.

I seen that before on another of your posts, thanks, the engineer wants my offsets close to stock, so even increases inside and outside of the rim. Looks like im shopping around for wheel builders! Cheers
