Muttley Posted October 26, 2009 Share Posted October 26, 2009 Hi guys, Im sure this has been covered before but as ever i searched through 5 pages of topics and got bored of searching so thought id stick my neck out and ask, at the risk of sounding a complete idiot. I dont really knoe to much about wheel measurements, only the obvious diameter 18",19",20" etc. Anyway, i am searching for some new alloys to replace my standards and wanted a set i could fit with no modifications being made to the car (lazy i know!!). Is there a set size i should be looking for? or are there loads of measurements thatl fit? Oh and im looking at getting 19" alloys with i deep(ish) dish. I havn't got the money yet so am only searching for a future purchase, but wont be able to spend too much unfortunately. Thaanks guys Muttley Quote Link to comment Share on other sites More sharing options...
Sarnie Posted October 26, 2009 Share Posted October 26, 2009 How long is a piece of string? Usual specs for 19 inch rims would be 245/35 & 275/35 tyres, on 8.5j front and 9.5j rears with decent offsets being around +18 to +25. There are a million and one other combinations though Quote Link to comment Share on other sites More sharing options...
Muttley Posted October 27, 2009 Author Share Posted October 27, 2009 Thanks Sarnie, cheers for the info "How long is a piece of string?" Had a horrid feeling that was going to be the answer . Thanks for the usual specs though, thats what im after really so i can just slap them on straight away with no hassles Out of interest (as explained in initial post, im not clued up with the rim measurements) what does the 8.5j and 9.5j represent? I assume that the offset is how far the rim sits from.....sumthing...brakes?? Sorry for the silly questions, gotta start somewhere. Cheers again Muttley Quote Link to comment Share on other sites More sharing options...
3FIDDYZ Posted October 27, 2009 Share Posted October 27, 2009 8.5 and 9.5 inch widths... Quote Link to comment Share on other sites More sharing options...
Chris`I Posted October 27, 2009 Share Posted October 27, 2009 Speak to the traders on here, Envy, Adam@Z1auto, Andy@Kudos, they all do wheels. They will make sure the wheels are of decent size, right PCD, width and offset for you Quote Link to comment Share on other sites More sharing options...

Jord Posted October 28, 2009 Share Posted October 28, 2009 The diagram Bullet Magnet posted is useful, however negative offset does not always dictate the amount of dish/concavity [is that a word?] a wheel will have. You can have a low offset wheel with little or no dish simply by there being alot of material on the back of the wheels [where it bolts to the hub]. This is referred to as the 'disc type' on most 2/3 piece wheels. As a quick guide - 17/18/19" is the diameter. 8.5J 9.5J is the width of the wheel, as measured from INSIDE the bead seats. A 9.5J wheel will actually measure 10.5" across from face to face - this is where confusion/misselling often occurs when people measure wheels rather than reading the labels/stamps on them. The 'J' refers to the shape of the bead seat - some wheels will be 'J', others 'JJ'. The offset is presented in either a positive [+] or negative [-] number. That being, the number of mm the back face of the wheel [where it touches the hub] is from the CENTRELINE of the wheel. If the back face is exactly in the middle of the wheel it would be ET +0 [Zero offset is still presented as a positive number]. If the back face is 5mm back from the centre it would be ET -5, 5mm forward of the centre would be ET +5. When choosing offset you need to take into account wheel width and work out what will fit. Remember if you add 1" to a wheel width it doesn't all go on one side - the easy way to work it out of 0.5" each side [12.5mm]. You also need to think about how aggressive you want your fitment to be. Usually OEM fitments are VERY conservative so don't be afraid to stray too far from them - good fitment can make or break a car. Thats the basics, without going into tyre-stretching etc. But I won't go there because it got me in trouble before Quote Link to comment Share on other sites More sharing options...
BulletMagnet Posted October 28, 2009 Share Posted October 28, 2009 Thats the basics, without going into tyre-stretching etc. But I won't go there because it got me in trouble before Lol, I remember, haha But yeah, about the offsets, even tho I have a decent dish on my Volks, they are still positive offset, +28 on the front and +23 on the rear. It's all down to the overall width of the wheel like Jord said. Always a good time to whore pics to help illustrate a point Quote Link to comment Share on other sites More sharing options...
Muttley Posted November 1, 2009 Author Share Posted November 1, 2009 Wicked advice guys, cheers for that. I'll keep you posted and will def have pics when i finally get round to getting some. Quote Link to comment Share on other sites More sharing options...
Muttley Posted November 5, 2009 Author Share Posted November 5, 2009 Hi again guy's. Found some 5 spoke BK Racing alloys i like the look of, was wondering if any1 could let me know if they would fit or not?? (Got a feeling the fronts wont fit over my Brembo's). Fronts - 18 x 8 ET30 Rears - 18 x 9.5 ET42 still not sure if i can splash the cash yet but am still keeping a keen eye out for alloys. Cheers Muttley Quote Link to comment Share on other sites More sharing options...
Ian Posted November 5, 2009 Share Posted November 5, 2009 Leave them, those rear offsets are shocking You would definatley need spacers with those. You need an offset of <25 IMO Quote Link to comment Share on other sites More sharing options...
Sarnie Posted November 5, 2009 Share Posted November 5, 2009 +42????????????? Would you even be able to see them in the arches? Quote Link to comment Share on other sites More sharing options...
