Raoul H Posted August 14, 2002 Share Posted August 14, 2002 Hi All, I may have an option on a set of 18" OZ Super Turismos. They are sized 8x18" with an offset of 50mm (according to Micheldever). The tyres are 265/35/18 (rear) and 235/40/18 (front) I have had a trawl through the archives on the subject of wheels and offsets but still have a couple questions: Is that wheel and tyre size suitable for the MKIV TT? Does anyone know if they might fit over UK brakes (front)? I currently run stock jspec 16's - the rear wheels are 9x16" and the fronts are 8x16" TIA, Quote Link to comment Share on other sites More sharing options...
Branners Posted August 14, 2002 Share Posted August 14, 2002 I would avoid those wheels if you can. They are only 8" wide, the stock 17" rims are 9.5 on the back and they use 255 on those. I ran a 265 on a 9" rear but that was pushing it really. Putting a 265 on an 8" wheel would be way too much and the handling may be badly affected. Whether they would fit over a set of UK brakes is also difficult to say, only way to be sure is to get them on to a car with UK brakes.

GavinL Posted August 14, 2002 Share Posted August 14, 2002 Hi... 265's on an 8" wide rim doesn't sound to clever for starters. 245's max was the recommendation I heard on that rim size before things start getting sloppy regards.........

JB I must admit I do have misgivings but the allure of having 18's after so long running very tatty 16's was too much for me to resist. I say 8x18" as that is the size I've seen in my Micheldever catalogue. Thanks anyways Quote Link to comment Share on other sites More sharing options...

Thanks for your help Gavin, Unfortunately, I am a lot of a novice when it comes to wheels and such. As I said in my reply to Branners, the thought of 18's was all too tempting. Perhaps I should 'lower' my sights to stock 17's instead of getting sooo ambitious:p At least that way you know uk brakes will fit...

Get a second hand set, put the later centre caps on them and get them refurbed it will transform your car Quote Link to comment Share on other sites More sharing options...
Dragonball Posted August 14, 2002 Share Posted August 14, 2002 I got 265/35/18 (rear) and 245/40/18 on an ACE 8.5 with no problems with handline - but this is prob the max Go for the 18's my friend - bypass these woosie 17's altogether!! You have to change your tyres anyway - and I cant see Micheldever selling you crap - but check them out first. What car were they on before? You will need a min of 55mm offset (If I recall) for the Toyota UK spec brakes - but stay tuned - I am running in my Hi-Spec ones now that need only 40/45mm Paul:cool: Quote Link to comment Share on other sites More sharing options...

Raoul H Posted August 14, 2002 Author Share Posted August 14, 2002 Hi Branners/Gavin/Paul, I spoke with Micheldever shortly after my posts and they suggested that a 265 section was indeed too wide for an 8" rim. The max width suggested was 245:conf: The wheels are on a MK3 at the moment (chap on the main list). It was also suggested that wheels of that profile would be suitable for a UK spec which implies that they will clear the brakes. I'll need to triple check this. But if it is the case, might I not buy the set and replace the rear tyres with a pair of 245s? Or would that be a case of 'form over function'. Decisions, decisions... Your replies have been very helpful and have given me food for thought so thanks again. Rgds, Quote Link to comment Share on other sites More sharing options...

Branners Posted August 15, 2002 Share Posted August 15, 2002 Originally posted by eyefi offset has nothing to do with brake fitment. well it does really, as if the offset is too small its never going to be far enough away from the hub to get past the brakes. However, offset is different depending on the width of the wheel, so a 50 offset on an 8" wheel is vastly different to a 50 offset on a 10" wheel.

Guest Nick Harris Posted August 15, 2002 Share Posted August 15, 2002 It is the splay angle or profile of the >spokes Offset is just a rim location number, zero would mean that the rim is centred on the face of the hub, 50mm #negative# offset the negative has been dropped because I cannot think of any car running positive offset so has fallen out of use, 50mm just means on 8" rims 6" is inside the hub face and just 2" outside of it on 10" rims the figures are 7" and 3". I have copied this from the Soarer forum. Another factor to bear in mind is the ratio of the rim width and the tyre width. There are certain ways to affect how a tyre will behave after you have selected a suitable candidate, one very interesting way is with the rim width. It used to be a guideline that if the rim was approximately 75% the tread width the tyre would be at its best, then the figure went up to 80% then 85% and now even 90% is used to provide very sharp responses as the sidewalls are nearer to the theoretical ideal. For example I run 17×8 at the Front and 17×9½ at the Rear with 235/45 (86%) on the Front and 265/40 (91%) on the Rear. Quote Link to comment Share on other sites More sharing options...
eyefi Posted August 15, 2002 Share Posted August 15, 2002 i did this b4 i saw nicks post, ive still posted it just to illustrate the point. the disc is green , caliper jade and wheel blue. any offset u want can fit (over euro spec brake calipers) so long as the design of the rear of the spokes allow.

Justin Posted August 15, 2002 Share Posted August 15, 2002 So for my J spec 17" wheeled car:- When I choose new 18" wheels (which I want to ASAP) should I look for 9.5 inch rears and what width for the fronts please? Ta. Quote Link to comment Share on other sites More sharing options...
Thorin Posted August 15, 2002 Share Posted August 15, 2002 Stock width's are 9.5 rear and 8.0 front... Although if I were to buy new wheels I would try and go for an extra half inch front and rear and put 255 on front and 275 on rears Of course it's not the size that counts, it's what you do with it Quote Link to comment Share on other sites More sharing options...
Thorin Posted August 15, 2002 Share Posted August 15, 2002 I got this from SupraForums a while back but can't find it on there now, it's quite useful. Let me know if the link doesn't work... http://www.darkstar.karoo.net/fitment.xls Quote Link to comment Share on other sites More sharing options...
