    Had 305 nittos on 18x10 faleens with eibach pro springs on my 01, didn't need the low profile bolt, no need to roll the fenders, but IIRC the H&Rs are a tad lower than the eibachs, but you should be good. Didn't look small at all

    You'll be fine with a 305 tire especially with the low profile bolts.

    Depends on the tire. I've found the G2's run wider than the older 555's. The 315/35/17 G2 was about a half inch wider than the 315 555R.

    I put a 285 G2 on an 18x10 FR500 and they fit perfectly.

    This work? If not I have a closer pic i can find. Don't really look like 30's though... My stock 40 series tires on my honda look way shorter.

    Isn't the sidewall # a percentage and not an actual measurement?

    I thought 305/35/18 meant the sidewall height is 35% of the width.

    So a 275/35/18 would have a shorter sidewall than a 315/35/18

    Good call, found this on the net:
    The aspect ratio is a percentage. It’s the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. In other words, it’s sidewall height divided by tire width.

    In this example, the aspect ratio is 65, meaning the sidewall is 65 percent as high as the tire is wide. To get the sidewall height, take the tire width of 215 mm and convert it to inches (8.46). Then multiply this by .65 and you get 5.5 inches, the sidewall height in inches.

    Only pic I currently have but they're about as wide as a 295/35 radial. I'm low on MM c/o's, low profile bolts, 3/8" spacers, & rolled fenders. It's no 315 or 335, but wide enough to hook my ported eaton on E85

    Others have done it, I don't think you'll have issues
