so i decided to put my new wheels on. bought tires and new lug bolts as well. was changing my rotors today and decided to do a test fit and the wheels are too big... im for sure gonna need spacers i just dont know what size. the wheels are 8.5x18 with a 35 offset all around. the pretty much touch the strut and im not sure if there will be clearance when turning the wheel after the tire is on. but ive seen on here people running the same size wheel and tires and even bigger with lowering the car anyone have any ideas on what size spacers? as you can see from the pictures its touching the strut. now with the 225 up front i dont think the tire would touch but im not sure.i also dont want it out too much because you can see that it is already pretty flush with the fenders. i didnt fit the back but it looks too be fine beacause it doesnt turn..

You might wanna get with Phister, he's kinda the wheel & tire Guru around here from what I gather. Send him a PM. But just off the top of my head I would make sure that the offset you think you got is what you actually got. It should be on the inside of the wheel somewhere. Also, under the OEM/Aftermarket mods Sticky there is a thread about wheels/tires and the right offsets and lugnuts and all the jazz ao I would check that thread and find rims with your same dimensions, then look at what spacers that calls for... from what I saw on the pics you posted I would say 5mm spacers but as to what kind of lugnuts and what length? Again I would check that thread. Good luck with it though, nice wheels!

Here's the link to the thread:

The standard wheels on a 2005 C are 7 x 16 with 31mm offset. If you do your homework (or perhaps the word is "should have done") and checked offsets when you change wheel width, for example such websites as 1010 tire
http://www.1010tires.com/Tools/Wheel-Offset-Calculator

you would have found that there is 23mm less clearance on the inside. Did you buy these wheels all on your own? Did a dealer suggest these to you? Perhaps you can return them. Without spacers they are all wrong. Sorry to be a bit harsh. But I am sure you spent lots of money on these.

 

Yea I've talked to him before when I was going to buy them. I was thinking 5 as well. And I already got new bolts so it looks like ill have to get longer ones for up front because it seems the only problem ill have is up front

 

Trust me I did all my homework and started a thread a few months back and everything should have worked out and everything has except its a tad close. I'm just wondering how everyone on here runs the same size wheels and even bigger on these cars without problems because even with spacers it will be close and no your not being harsh I understand where your coming from completely I wanted the stock look so I got Mercedes wheels just from a different model but I did all my homework I was told with 35 offset I should have no problem without a spacer. Everything else was ok there just close to the strut so ill need spacers

 

You cant look at the wheel with car jacked up like that. You have to remember your suspension is at full travel with it jacked up. The wheels are going to sit higher up on the suspension then where it is sitting in your pics.. to really test fit you'll want to either jack up the wheel to height it'll sit at when the car it's on the ground or place some boards under the wheel and jack the car down to see where it did in on the suspension.

 

True for the rear suspension, but the McPherson strut is fixed to the knuckle, so the hub is always in the same position relative to the strut.

 

that Stock jack Looks Scary looks like you are on a hill there.. be careful

 

I did notice that so it's a good thing it turns with the wheel

 

That's actually the hack that came with my car lol

 

Yea I thought about that too so I might so it today. I remember in your build thread you had 8.5 up front on one of your set ups didn't you? What was the offset there and what size spacer did you have?

 

I think what Phister was trying to say was addressing the OP's concern as to the wheel sticking out too much and not looking stock. I think what Phister was saying is that at ACTUAL ride height the lip of the wheel will move up and in parallel to the strut since the strut leans into the car. Even if with 5mm spacers the wheel/tire will still be well inside the fender IMHO.

 

i mean as far as how it sits with the car im happy with it now and your right a 5 mm or even bigger wouldn't be bad its just that i for sure need spacers up front from what i saw yesterday and in the pictures lol its metal on metal. the back is fine but the front is damn close and also once i get the tires on it looks like it will be close turning the wheel because of the inner wheel well how it has the plastic covers. but then again it could all set up different when the car isnt lifted

 

the stock jack is crap and to make things worse you jacked it up on a soft surface

 

Yea there not the best jacks lol and its on concrete the grass starts the hill so it's pretty hard and flat where it is

 

At least he has a jack....My car didn't come with ANYTHING! the tool bag, the jack, the manuals, ONE Key FOB (number 2 of the original set). I'm not too happy about that...

 

That does not look like et35 to me :x

 

it doesn't look like it but it is. ive measured also to make sure they didnt send me the 9.5 ones there all 8.5.. i have no idea. im going to get the tires mounted and then do a test fit on all 4 and get the car to its natural height and see if it changes...

So I'm getting the tires mounted on the wheels tonight and probably tomorrow ill throw them on to see how they fit. I browsed the aftermarket wheel thread a but and from what I gathered up front a lower offset is better like the 30 range. Even though people on there said there wheels fit fine with the same specs as mine I guess I'll need spacers. I'll be able to confirm that once I get the wheels on and the suspension at stock height but who knows. So I guess if I need some maybe 5 up front? That would bring it to 30 correct?

 

Yes, offset is measured in mm so... Adding 5mm with the spacer brings it to 30 offset which means that the mounting "face" of the wheel is +30mm from the absolute centerline of the wheel (+ means toward the outside of the car). Good luck tomorrow and please take some pics for us to enjoy.

 

I just bought the same wheels for my 06' c230 sport. Front 18x8.5 et30 and rear 18x9.5 et35. Just put wheel on car and the front was about 1/4" from strut, pretty close since I'm putting 235/40 tires up there and 255/35 in rear. I do have 10 mm spacers but I hope I don't have to use them. My rear stock bolts are too long for the rear wheels, they tightened down but left probably a 1/8" gap so I will need to shorten them up. Let me know how yours works out, I don't know much about offsets so if yours is 35mm and rub the strut what will my 30 mm do?

 

Your 30 won't and my 35 just bairly does but tomorrow I'm putting them all on so they might back way a bit once the suspension is down and 235 up front? That's gonna be tight. I have 225 and let me say they look fantastic it's a perfect fit not stretched at all and flush with the lip. The back I have 245 and its a nice beefy tire. As for yours the back I think is 35 stock someone correct me if I'm wrong do you shouldn't have a problem there

 

Oh yea man even if they are too close to run ill still take some pics before I take them off.with the tire on them they sit good they almost concave so if I can get it all to work out and get it flush it will look great

 

And yea if yours was a forth of an inch away that's why cuz your offset is 30 and mine is 35 that's a 5 mm difference so I added a 5 mm spacer it would up me that far and down to 30 et. And as for lug bolts search raddirectusa they changed their name to Otis something but that's where I got mine from good service and they make them for our cars at any size. The stock is 39 mm I had to order 27mm because I needed shorter lugs. The front isn't a big problem but you don't want to hit ye parking break in the back lol

 

Cool, can't wait to see pics. I'll have mine installed on Thurs. Waiting for tires to be delivered on Wed.
