Ok wheel arch measurements are in for a european nv200....
Length is 28 inches as shown on tape measure. Measured from the wheel arch lining retaining clip to the other side.
Width is 13 inches. Measured from the the retaining clip shown in picture to the end of the arch. (In the picture it looks like the reading is 14 inches but that's just the angle of the picture, definitely 13 inches.
Any comparison will be much appreciated.
Hi John--Sorry for the delay. I get pretty much the same measurements as you. I measured front wheel opening length at 28" measuring from the same clip to the front of the opening at the bumper. The width might be slightly deeper--from the clip inside the wheel well to the edge of the tire was about 13.5", and 14" to the lip of the bumper. But that may just be measurement/eyeball error. It's raining and I didn't bring a straightedge out to the van.
Recon seems to have done their research on other things, so I wouldn't tend to doubt them, but it may be worthwhile to get a rim from a junkyard to see. A local tire (or tyre, in your case...:grin

shop that's trying to make a sale would probably fit you up a new or used tire just to check it out, maybe charge you $20 for their time. I've had good luck in the past catching a small business on a slow day, and the owner is usually happy to put one on of his guys to work fitting up a tire if it's not taking away from other work, as long as you act like a serious buyer.
