heraldcoupe Posted September 21, 2013 Share Posted September 21, 2013 One of my friends is selling some 13 X 5.5 rims with a +18mm offset off a formula ford, Everyone seems to recommend a +25mm offset for that size rim so i just wanted to know if a +18 offset will be ok or will my tyres scrub the guards? They will have 175/70 tyres. I don't have the option of trying them on my car before I buy them.Thanks Quote Link to comment Share on other sites More sharing options...

thescrapman Posted September 21, 2013 Share Posted September 21, 2013 Depending on what type they are they can be very expensive.... :-) Quote Link to comment Share on other sites More sharing options...
mikeyb Posted September 21, 2013 Share Posted September 21, 2013 worth a tidy sum of money - if they are cheap, buy em, try em and if no good to you then flog em!if round and undamaged etc. could fetch around £300 on fleabay :) Quote Link to comment Share on other sites More sharing options...
heraldcoupe Posted September 21, 2013 Author Share Posted September 21, 2013 Good condition they just need to be painted £30 a rim, only weigh 5kg. Im pretty sure the offset will be ok They are made by a Australian company http://www.performancewheels.com.au/Home/Wheels.asp?theGroup=S&Cat=Motor+SportLook like this Quote Link to comment Share on other sites More sharing options...
mikeyb Posted September 21, 2013 Share Posted September 21, 2013 ah, I thought you were referring to "original" 60's dunlops Quote Link to comment Share on other sites More sharing options...
junkuser Posted September 21, 2013 Share Posted September 21, 2013 The offset should be to bring the tyre centre to factory specification for the car, so it should be that the tyre size is what dictates the clearances.I accept that people change offsets for different reasons, such as caliper clearance or special purpose vehicles, but this is not ideal for a car used for its original purpose.

mr_seth Posted September 21, 2013 Share Posted September 21, 2013 It will partly depend on whether your car is lowered much. We had occasional scrubbing issues (on the bulkhead at full lock as well as the wheel arch) at one time with some 5.5" wheels but a switch to 165/70 tyres solved the problem.

Tim Bancroft Posted September 22, 2013 Share Posted September 22, 2013 Bit worried that they might foul the wishbones, as the offset does'nt look brill.Take the car to your friend and try them on it. Quote Link to comment Share on other sites More sharing options...
thescrapman Posted September 22, 2013 Share Posted September 22, 2013 I am sure the offset on some of the 5.5J oval hole wheels is 16mm, so 18 isn't thaat far off.I'll have a look at some of mine later.Cheers Quote Link to comment Share on other sites More sharing options...

Also a standard rim is +13 so the rim will be 30mm closer to the wishbones than a standard rim, I have measured it and it should be ok. but the tyre will rub full lock onto the boot of the steering arm.And cheers thescrapman be interesting to find out what peoples 5.5s are actually offset Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted September 23, 2013 Share Posted September 23, 2013 The 5.5" Revolutions currently being sold are quoted as having a 25mm ET. Some people have reported these as being extremely close to or even catching on the upper wishbones and requiring spacers to fit properly. On that basis ET 18 (if you mean ET?) sounds like a better bet.I do know that ET13 works fine on 6" wheels.Nick Quote Link to comment Share on other sites More sharing options...
Martin M Posted September 23, 2013 Share Posted September 23, 2013 Hi,the Minator 5,5 x 13 ET 25 definitely catch the upper wishbones. Needs grinding.Martin Quote Link to comment Share on other sites More sharing options...
heraldcoupe Posted September 24, 2013 Author Share Posted September 24, 2013 Cheers that's what I was after, I have never heard anyone call it Et before just +- offset (Like eg.)If a 6" works with +13 a 5.5 will work with +18 thanksI was also thinking +25 would be really close to the wishbones....

MarkB Posted September 24, 2013 Share Posted September 24, 2013 Just for information I have a set of plain steel dunlops 5.5 x 13 ET 16, they fit a MK3 Spit and a Vitesse, but rub on the arches of my Mk2 GT6 fitted with rotofex. Tyres are 175 70 13. The later Spits and GT6 have more space in the arches but not sure how they would fit with the later longer shafts.Mark Quote Link to comment Share on other sites More sharing options...
uksnatcher Posted October 1, 2013 Share Posted October 1, 2013 Also Herald/Spitfire front hubs/uprights have a slightly shorter hub than the GT6/Vitesse IE the offset needs to be approx 5mm more if fitting to a Herald/Spitfire compared to a GT6/Vitesse using 13" 6J rims Quote Link to comment Share on other sites More sharing options...
