Absolutely positive the outside dimensions are no larger than 18" x 12"? Not inside dimensions but rim to rim? Thanks!

The rim is 10 1/2 inches from outside to outside. The inside measurement is 9 1/16 inches. Hope this is useful to you.

Hi it's quite deep, about 18 inches but not as big in the rim area as I was hoping

outside dimensions are 12"x8 and 1/4". Mine is the large size which I have not been able to find again. The only one I can find now is smaller.

The answer I gave was right after measuring it. 12x14 with 18 inch opening.

Nothing is 18x18. Outer size is 30x24. Rough opening is about an inch smaller.Ours look great and work well.

Hi, thanks for your question. According to the product page, the dimensions are 13" in Diameter x 18" in Height. For future reference, this information can be found in the "Product Description" section of the product page. I hope this helps!

19.5 inch outside edge of rim to outside of rim edge, 18.5 inside edge to inside edge.

It's all rounded so it's hard to get exact measurements. The inside rim at the top is a little larger than 8", the outside rim at the top is just under 9", the bottom diameter is about 4".

You should contact the vendor directly for exact dimensions. The ones that claim they are 12" by 12" aren't. I ended up not buying from this source, so I can't tell you the exact dimensions. The ones I bought locally were closer to 11" x 11.5".

No the 2 pads ride on the tire side wall and space rack away from rim. It probably will not work w rims larger than 18".

The space measures a little shy of 18 inches. hmmm..I see the other response..but I just measured with a tape. It is slightly less than 18 inches.

Sorry, previous answer was "outside" dimensions..... Inside measurements are just over 7 3/8" by just under 14".

I bought a 12 in. (http://www.amazon.com/gp/product/B004L0XTXA/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc;=1). It doesn't sit on the rim, but it works pretty well.

Yes, the width to the outside of the rounded rim is 29". Just under the rim measures about 27.5" to 27.75", and the inside width at the top is about 28". Note that the box is slightly tapered.
