Anyone help im looking at some new wheels does anyone know if 245 40 18 with an offset of 29 will fit and 8.5j. Ill need spigot rings for the centre bore but dont want to do that to find out the wheels dont even fitan tyres rub.
Thank
 
it will be very close with a 245 tyre, i'd say that you will get some contact to be honest , can you not try one first before you commit to buy.
I am running 235/40-18 on an et35 and the rears don't rub but are very , very close when the car is occupied etc so when bumps happen it is close, a lot of guys run wider but on a stretch basis so have a bit of space, maybe an ET33/35 would be better suited to you, do you have lowered suspension , if so that will a factor too.
don't forget, an 8.5j is going to be 6mm wider either side so with that et29 offset + 6mm extra rim width that will effectively make your rim another 6mm further out towards to wheel arches ontop of the offset , so a standard 18" A4 B7 rim with an offset of 43 by going to a et29 your moving the rim out 14mm front and back then add that 6mm extra rim width on the outside edge and that's going to be 20mm , probably way to much mate.

any pics to work with.

Thanks for the info i currently have the standard DTM suspension which if i remember is 20mm lower than standard S-Line so i dont have alot of room but i have a bit. They do fit the 12mm spacers on the rear which i dont have but i know people have put them. But not seen any pics or cars in the flesh so not seen the gap that is left. The wheels im looking at are for the A5 Sport. Ill get a picture of my wheel gap to follow.
 
Hope they are clear enough

the rears can normally get away with abit more offset than the fronts,
i'm on ET35 with no spacers on 235/40 18" , I could prob get waya with another 5mm on the back but that would be tops as when the car is occupied you cant get a finger under the arch , so that 5mm may just tip things over the top and get tyre rubbing.
fronts are just right.
my is on H&R lowered 45mm allround so 20mm less than the s-line it started with.

Looks smart. I think ill try and get a set to try before i buy i did have a look at the clearance on the front but the top arms look as if they would hit but will try if i can i post my findings. Thanks for your help. If anyone has tried 245's with a 29 offset please post :)
 
Tried and tested no rubbing or catching old wheels are 235 40 18 offset of 43 8j rims new ones are 245 40 18 offset 29 8.5j rims.

so a good job done chap, rears are just about on the edge, have you tried it laden on a corner, what about fronts, I cant see them from your pics but are they ok or do they stick a bit, a lot of owners have fond that et29 with 245's on 8.5j tended to stick out and look a bit too chunky, are your ok.
 
Yeah not bad ey. Ive attached a pic of the front and i checked out the rear when i had the front up so hopefully that was as low as it wud ever get unless i hit a massive hole but then i think ill have more to worry about haha. Dont get me wrong they do look chunky in the flesh more so than in the pics and it is on the edge i dont think you would want anymore but now ive eliminated the need for spacers aswell...quids in!! :)

ah yes as I thought , that ET29 with 8.5j with 245's on the fronts does push the rims out a bit, not a great deal more but deffo more than normal.
fronts can look less chunky with an et33 or et35 or ET 42 but all down to personal choice.

Sorry to jump on this but what about 19" 8.5j et48? Has 255 tyres in ATM and I'm on standard suspension....
 
Mine are 18 9j et28 I'm running 215/40/18 on the front with stretch but they scub like a bitch at it current ride height. I'll be raising it up today.

If looking at mine is anything to go by i would imagine they would rub on the inside with that offset, they are not far off on mine with the 29 offset but im not sure for definite.
 
So rather than start a new thread, I'll ask it here.

Seen 2 sets off alloys:

18x8.5 et29 225x40x18 tyres, what will the fit be like?

18x9 et52 225x40x18 tyres, will they fit?

Standard Audi A4 Quattro wth SE suspension!
 
I don't think either of those are going to be ideal dani , depends on what your end results are to be. 18x8.5 et29 will stick a fair bit on the fronts, but may be ok on the rears, 18x9 on an et52 may not be too bad either , Et33 or 35 if on a 8j or 9.j rim avoid most bodywork contact issues and still look nice.
Those on an ET52 are going to be approx. 10mm further inwards , plus the 13mm extra either side for a 9j over the 8j and your approx. on an ET39 so your only gaining 4-5 mm extra width over oem rims, or the same as putting on 5mm spacers.

my 18 x 8j rims with 235/40's are an ET33 and when fully loaded there is very little space left between tyrewall and wheel arch inner edge, it doesn't rub but if I was on more than et33 they would rub.

So the first ones are a no go then.

So do you think the 9j et52 will look daft?

I wouldn't say the 1st set are a no no. Mine are ET28 9j up front and they sit perfect

but your have a big old stretch on those tyres chap, if you put tyres on without the stretch they would look way different, also if you ran a plumb line down your front wheel arch outside edge I bet you those rim edges are prettywell inline if not a shade further out.
A lot depends on if you are fitting a tyre that is effectively too narrow for the rim or fitting one that is not or just a shade under width.

no, don't see why dani, the 18" 8j oem rims are et42/43 depending on rim , if your going to an et52 on a 9j the rim is 26mm wider but the offset is now 13mm more so that put it approx. et39, so your going to be 4-5mm wider than what you have now, that's ok to be honest and you wont have any issues either.
if you want to go out further then you can add spacers later, if you added 5mm allround then you'd be on somewhere around an et34 , all depends on the look you want dani, and that's your choice alone i'm afraid.

another problem is that unless you have lowered the suspension to s-line or a bit lower they may look to be a bit chunky if you get my drift, whereas with the reduced wheel arch gap they will blend in better.

i'm not expert on this subject dani but can safely say I've spent way too much time trying to work out a whole array of possible fitments to my old bus, the vermillion messup being one of them. a lot of offset will work but depends on if you are strectching a tyre to gain more wheel arche clearance or not.

the offset you are looking at I tried inc using spacer to rims to fit (without success) and here are a few pics with non stretched rubber, you can see what I mean by looking chunky on the fronts.

two pics dani, first is oem 18x8j et43 , second are also 18x8j same dimension rims etc but ET33. 10mm make all the difference combined with H&R 45 allround.

I appreciate the input rob, thanks for the time and help.

I see what you mean about the et, I'll think it over, I won't but the et29 but I'm seriously giving the et52 thought as they are only £180 with 4 good tyres so is be able to sell mine for the same so win win really, can then always just buy another set of 18 and swap the tyres over. Just need the las to get back I. Touch.

no probs dani, I think you'll be fine with them, like I say you can allways add 5mm or a bit more by use of spacers if needbe, just one note of caution dani, be very carefull with the design of the rims as not all rims will be the same fit as patterns will effect offset etc aswell, if they have any sort of rim lip or are dished a fair bit either concave or vex you may find other issues to come to light such as caliper clearance etc , just a heads really so you can be prepared for anything.
best of luck
 
Just a quickie as I'm being lazy and still in bed.....but with the ET52 you may find that they will rub against the suspension.
 
thanks for the heads up carl, you have made my double check my input now, that's the problem with writing a reply late at night after a beer or two...lol,
right lets start again.
oem is lets say ET43 on a 18x8j rim, so changing to an et52 will move the rim inward by approx. 9mm, then going onto a 18x9j rim will equate to an increase in rim width of approx 13mm per side (26mm overall) .
so if you stayed on et 43 you'd have just that 13mm extra on either side, which is probably not to bad , since your going to anET52 the difference between the et43 and et52 is appox 9mm which will move the rim 9mm inwards so the rim will be approx.

just as an example which does clarify my info based on if you already run 18x8j 235/40 rims on an ET43 I was correct just omitted the may rub on suspension part....ooppps.

and well spotted carl yes they may well rub on something ....i'll poke myself with a sharp stick next time ..lol

So then chaps,how did everyone get on wheel their wheel upgrades, good or bad or just gave up.

rob
 
After running mine for a few months now I have notice I splat alot of road muck all over my arches an sides of the car because of the wheels sticking out abit and it does rub when I go over a big bump abit quicker than I should but other than that no other issues. Hope everyone else sorted theirs out.
