I recently purchased some 18x8 G35 7 spoke 2003-2006 stock rims. On the rear the tire size is 235/40/18, on the front tire size is 225/40/18. I had some rubbing on thre rear so I switched the front and the rear, now there is no rubbing but the gas mileage has gone way down from approx 28.5 mpg to approx. 22.5 mpg. I use the tire size calculator, stock size for my car is 195/65/15 with the 225/40/18the radius is the same 12.5 in, diameter is +.1 in (25.5in to 25.6in), circumference is +.3 in (78.5 in to 78.8 in), revs/mile 807.0 to 804.0 So basically the 225/40/18 are about the same size as stock, the tire is wider so I realiaze the difference. With the 235's the radius is +.2in, the diameter is +.4in, the circumference is +1.3in, revs/min 794.0. So now that i have lost most people, I want to stop the rubbing, I dont want to lower the car but I think I want to get a little bit of negative camber to pull those 235's in a bit to stop the rub. I could go to the 225's but I'm not sure what to do???

 

try rolling out the fenders, but i'm surprised you tires rub without you car being dropped, i have 235/35/19 with the tires tucking under the fender and dont experience any rubbing. but then again you do habe 2 different tire sizes. i would go with 235/40/19 all around, more meat on your tires but check the offset on the rims. you want to make sure you have 40-45 offset, if you have a 38 offset your wheels poke out and might be causing the rubbing

 

What Accord are these on? My +45mm wheel rub in the back on large bumps, but I too am having a hard time believing the rub on a stock suspension.

In order of lease expensive to move expensive:
- Find where it's rubbing, if it's the plastic bumper cover, cut it with a rotary tool. If it's the metal fender, get it rolled. Many shops will roll fender for about $30-50 a fender.
- Stretch the tires. It looks kinda goofy, some people like it, but you could get away with a 225 or possibly a 215.
- Sell the wheels and get something with an offset that works.

 

I have no idea what off set the rim is. I bought them off craigs list, i was told that they came of a G35 Infinity, I didnt ask what year. I looked up the wheel and found it came 2003 - 2006 Infinity G35.
My 2006 Accord 4DR LX is stock everything execpt the tires and wheels

 

Offset is frequently stamped on the backside of the rim, somewhere. Often with the letters "ET"...
Or you can measure it yourself with a couple straitedges & tape measure.

Stock offset for your car is +55mm, +42mm is about as far as you can push it to get the wheel to sit flush with the fender.

I'm betting these G35 wheels stick out pretty far from the fenders, like this:

 

Yea, the wheels do stick out. I don't know if they stick out that much but that's pretty much what they look like. I am going to get the fenders rolled and I'm hoping that will help the problem.

 

if your accord is not dropped, rolling out the fenders won't fix your problem, the issue is that you have rims on your car that are not made to be on an accord. G35 offset are +30, which are specific for the infiniti not honda , best bet is just put them back on craigslist and make your money back and buy some with a +42-55 offset which will fit under your wheelwell
