New Tyres Fitted-Slightly Confused

yes, mike thats the spot, funny thing is its doesnt look like it could go on any tighter as it is resting against the hub. the wheel looks like its fitted properly i just am so confused why i have the gap. both fronts have the same distance. :(
 
I'm struggling to understand where this 'gap' is. Mike is talking wheel to hub and others are referring to tyre protector which is between wheel rim and wall of tyre??

Also not sure if those wheels are staggered, so have you checked you have the 8.5 on the back and 8 on the front. If not staggered they'll all be the same. Easist way is to measure any similar width point and make sure th rear is 1/2" wider.
 
ok, jeeper that makes sense, so basically they could have put the wheels back on e.g rears on the fronts would this explain the gap then? nothing wrong with the tyres but they wouldnt cause the problem as they are the same size tires although they seem alot more chunky. mike is correct the gap is between the wheel and hub, you can now see the side wall of the hub where as i couldnt before as the wheel was flush with wheel.
 
tyre size shown is the right tyre size for the front.... Style 135 for Z4 is staggered (or should be...) they have put the right tyres on the right wheels haven't they? as cj says measure 'em to be sure...

can you see anything in the 'gap' mentioned?
 
yes im sure they have. tyres are correct 225/40/18w on the fronts and 255/35/18w on the rears.(same as the bridgestones) as for the gap no nothing, on the back of the alloy wheel the metal seems to have overhangs all the way around so when fitted just rest against the hub tightly whichs seems normal to look at but i know this wasnt like this before. the wheel doesnt fit inside the rotor or anything does it just leans against it.
 
gannet since you have the same tyres if u get a chance to take some close up pics on the front and rear wheels that would be great.
 
Hey - I've got the same wheels as you (same age car) - just went and took the same pic but for some reason I can't get it off the camera.

Anyway, I have the same gap; are you sure you didn't have it before?
 
hi, yes im sure, it really stuck out to me this morning as i only got the tyres yesterday. i can also tell as the calipers sit little deeper into the wheel hence the gap. shame you cant get the pic uploaded, anyone else got the same wheels as me that can take a few photos? sorry im a right pain in the bum.
 
OK - my last post crossed with another so I now know where your gap is as per Mike's suggestion.

I see no reason that it's possible to have any 'new gap' unless the wheel is not tight or is trapped on something. Highly unlikely as the ride would be aweful nd it's the same on left and right.

The only alternative is therefore you have the wrong rims on back and front.

Let me be very clear about the wheel/tyre mismatch. It is perfectly possible to fit the front tyres on the wider rear rims and rear tyres on the narrower front rims and then bolt them onto the car with the wider rims at the front but all the tyres appearing to be in the correct place. You can only eliminate this problem be physically measuring the wheel widths or taking them off a nd reading the 8.5J and 8J sizes.

Perhaps the rears woult sit different enough on the front for you to see something.
 
oh god i really hope they havent done this i had them fitted at ATS surely they cant be that stupid :fuelfire:

C'mon then get outside and check it.....

Put your fingers around the front rims to the struts and see how close. If less than a finger between alloy of rim and strut bingo - wrong rim on the front.....
 
I'd be jacking it up and whipping off a front wheel and checking the print on the inside of the alloy... MIGHT be possible putting it on full lock and crawling under on your back with a torch to see in.

It does sound like they have fitted the 255's to the 8", and 225 to the 8.5", and then fitted the 8.5" at the front...

OOopps! If this is the case please let us all know so we can avoid them in future. Muppets. How dodgy would that be if you were not the kinda person to check and run it for a while!


Hope you get it sorted soon!
 
right since im not technical minded at all ill have another look in the morning and take it straight to ATS so they can swap them round. ill let you all know what the outcome is. thanks for all your help guys. :thumbsup:
 
well I think it's fine, same as mine as you can see in the picture above. Reckon you could be imagining things when checking out your new tyres!

do you know how many wheels they did at a time? I believe they have probalby put the front tyres on the rear rims.

Are both sides the same, as they may have only messed two wheels up.

I think your best be it to measure the inside width of each wheel to see if they have fitted them wrong or not

*** Just seen that I miseed a lot of posts before I put this up so ignore any duplication ***

For sure.

When you consider 2 different rim sizes that unless you read the casting or measure them it's hard to see, 2 different tyre sizes and some tyres being unidirectional then you have a lot of possibilities of a screw up. Added to that refurbed wheels like 108's are not unknown to have the wrong 'stars' fitted to their respective wheels :headbang:

Good job you mentioned that, as I thought the stars were generic and the outers the different bit. I guess you can tell by measuring the hub depth from the back of the spokes to the hub seat!?
Or is the dish of the face of them actually different too? (looks the same)

Dave

Not sure if they are the same but they have different sizes on the casting of 8 and 8.5, so if wrongly assembled any tyre fitter from then on will likley get the wheels mixed. The star would of course be one place to build in any offset changes as of course just as easily the outer part of the wheel.

I can confirm the stars are different and guess the rears have more of a boss, I say this as I can feel the difference when cleaning out the wheel bolt holes.
 
srhutch - you need therapy if you can feel a difference in offset while cleaning boltholes :rofl: :rofl:

Well 'el' you have something to look at in the morning. I really do suggest you measure or ideally remove a rim (the one you think looks odd) and fully check before going to the garage. Also if you know your car really well as you suggest then look for those small kerbings now on the backm or the rears covered in brake dust instead of the usual front,etc.

Nothing worst than a muppet at ATS telling you he didn't make a mistake :headbang: but I know what I'm putting my money on, especially if the jacked up and did one side of the car at a time.

I will see if I can take some photos on the way to work tomorrow morning :thumbsup:

bear in mind though I have different wheels :D
