Default 18X7.5 w/ 225/40/18, What's wrong??

Ok, this is an embarassing question, but this is my first time getting wheels. After doing a lot of research (or so I thought) I bought rims of that size with that size tire.

I'm getting some rubbing from my caliper. I drove it about 4 inches and noticed my car wasn't going into gear like it should. I got out and checked the wheels, all clearances are fine except the damn calipers in the front. Do I need spacers for this problem?? How do I fix this? I really don't want to change tires again, but I don't want to leave my car parked for much longer. Anyways, thanks for any help.

Also, if there are aftermarket calipers or something that are smaller that would hlep too, just don't know where to find them.

What's your offset on the new rims? If its higher than stock +45, you might incur some rubbing. Here's some help with understanding offsets...

Wheel Offsets

I have the same rim size/tire size set-up but with a +35 offset and I have no rubbing issues. Also, if you're lowered you might get some rubbing. You are going to have to give more detailed info on your set-up in order to get your question(s?) answered.

wow, your still around hyghynx? what no phone calls.........LOL.

what rims are you running?
as for calipers, you may need to run spacers, what offset are you running on your rims? tires should not be part of this problem.
post pics so we can be of more help

I guess my offset is the same as with my stock rims. It doesnt say what it is so that's my assumption. Here are some pics:









In the second picture you can kinda see where it's rubbing. Will spacers help with this? Thanks again![/img]

i can tell you why its rubbing too, i have seen this before.
in an effort to get that all important lip people are willing to do anything for, niclude sacrificing things like fittment and sometimes common sense, the spoke is so concave that its rubbing on the caliper at the apex of the arc. You could also grind down your caliper as well a few mm. but HKS is right, get a 3-5mm spacer and it should fix your problem

Ya, I looked at my order as I couldn't remember the offset I got. It was supposed to be 48mm. I got 45. Like I said I did a lot of research and wasn't trying to sacrifice anything for this. The sender is sending me some 3mm spacers on their behalf, along with a new tire iron (the one they sent me cracked when I went to tighten my lugnuts, so my car is undrivable for a few days ... )

Anyways, thanks again for all the help!

IMO 45mm is too high...... anything higher then 38mm will look like its tucked under the fender. But if the spacer works then that is all that matters. good luck

By me getting a 3mm spacer it is supposed to make my wheel stick out by 3mm more... At least that's what I was told.

it should........but you got the wrong offset to begin with from the looks of it, and you may expereince some vibrating due to running that type of a spacer. You wont know until its installed, but my experince with slip on spacers is they vibrate and can damage your hub/axle. i would just take the wheels back and tell them to get you the right ones. nerek on S/L has the same rims with the right offset and has never complained of these issues.

yeah, like he said. Its funny, but i have seen many use 50 offset and swear that it fits just fine? and with 8.5 width. Doesnt sound right to me, but who am i to argue if they have them on their ride without problems. I think anything with a 8 or 8.5 width in 18's should stay below 38 offset and no less than 33... but the front and rears are a little different, and i have seen 30 offset on the rear that works well, but with 215 instead of the 225 tires.

Later....

That's most likely your wheel offset. I have a similar problem. I have Enkei RS7 and they are 19x 7.5 with 45mm offset. I installed new brake pads, now even when i slightly turn my steering wheel any direction, i hear rubbing/ squicking noise just like you would hear when your are stopping with brand new or worn out brake pads. I think wheel spacers would help. Also i hear that if you find where exactly your wheel is touching the caliper, you can grind the caliper probably a couple millimeters which would help you get more clearance. However i suggest you do that with a mechanic who knows what he/she is doing.
