225/40-18 on 18x8 rim 40 offset

[BMwiththeADD]

Would like to resurrect this thread to ask nyknick1015 a question:

a 225 on a 8 inch rim would fit fine.. i have a 225 on a 8.5 up front and i have no problems turning or rubbing and i am pretty slammed i would say. you wont have that stretched look tho so i dont know if your going for that

i cant really say if its gonna sit flush because that depends on your offset now

I assume thats a pic of your ride nyknick1015, and its a pretty sick ride. Can you say what offset and diameter your rims are?

I am trying to plus-size while avoiding the rubbing problem just like the original poster. My first go at plus-sizing resulted in the rubbing problem in the rear. Bottoming out on speed bumps or pot-holes would cause rubbing at the top of the fender. To make my case educational for others on what not to do, here it is:

CAUSED RUBBING IN THE REAR -- '00 Sedan
Tires: 215/50-17
Rims: 17x7.5 offset 40 mm

The key is that 40 mm offset. The rims I chose were also available in a 45 offset, but I think the Discount Tire guy advised the 40s because he could see that was the offset of the OEM wheels. Problem is when, you go with wider tires, you need them to "tuck in" more to avoid rubbing, therefore you need a comparably higher offset (or else modified fenders). Hindsight is 20/20 as they say,

So in my second time around, I'm doing trying to do better homework to avoid the rubbing problem. I found some 47 offsets in 18x8.5 that I am considering putting on with 225/45-18s. I just hope that gnarlier setup wouldn't effect the brakes or the tracking too negatively.

hotchef181818, did your situation play out yet?

I have an 8" rim in the rear with a 40 offset in the rear and I had to get rid of the rear bumper tab completely and it still rubs if someone is sitting in the back....i dont know how low your car is but mine is low and I have a 235 tire

This is RedRyder's car.


I have 225/45/17's on 17x8 wheels with a 40 offset. I also am dropped with no wheel gap. I do not rub really at all unless under very hard cornering and hitting bumps in the road.

thats not his car. his car is in his signature picture.

youre not rubbing at the top of the fender, youre probably rubbing on the rear bumper tab, if anything at all. youre wheels are only .5" wider than mine, .25" on each side, so thats not much and i doubt its rubbing bad at all. i dont have my rear bumper tabs, but im sure i probably wouldve slightly rubbed on them if they were there. its really nothing to worry about.

oem wheels are not a +40 offset. theyre more like +54 or +55. i think it veries slightly, like 1mm or so, between different oem wheels, im not too sure though. i know my steelies were +54, and i know the oem wheels on 6g's are all right around that.

So in my second time around, I'm doing trying to do better homework to avoid the rubbing problem. I found some 47 offsets in 18x8.5 that I am considering putting on with 225/45-18s. I just hope that gnarlier setup wouldn't effect the brakes or the tracking too negatively.

an 8.5 +47 is going to be a tight fit...on the inside. if it wont hit the shock body, itll be close.

Yes, everything fits fine now with the 225/40-18

I have a feeling you are right. I would also hear a big sound when bottoming out in the rear. It sounds too solid of a sound to be the relatively flimsy fender. My car is at an alignment shop right now getting the front-end repaired; your post moved me to call the shop today and have them check out what the rear wheels are hitting. Thanks for the heads up Sketch.

oem wheels are not a +40 offset. theyre more like +54 or +55.

You're right. The Evans Tire website says +50 for the OEMs. I knew that once and forgot. How then could Discount Tire advise the juttiest wheel in view of the juttier tires I was choosing?

an 8.5 +47 is going to be a tight fit...on the inside. if it wont hit the shock body, itll be close.

I got underneath one time just too gauge how much inside clearance I had at both the rear, and at the front, lock-to-lock. I came away thinking there was plenty of space in the rear to play with. But I'm just an analytical-type with a ruler, not an experienced mechanic. I'm put off by the fact that I haven't come across any real-world examples of people running 8.5" wide rims, so I'll have to put off judgement for a while til I get more info.


Thanks to AllGOnoSHOW, Mojeans69, and hotchef181818 too. A lot of helpful info in here. Think I'll hang around awhile. Eventually I reckon I will post my before-and-after horror story/success story in the dedicated wheel fitment thread. I can already vouch for what doesn't work.

Thanks Matt.
