I recently bought this MENG Ford F-350 kit off the shelf of a hobby shop in Las Vegas.
After reading this thread, I looked especially close at my chrome and tires.
The chrome looks comparable to factory kit chrome of my Fujimi, Aoshima and Revell kits.
This image is compared next to the Revell '99 Chevy Silverado
The tires are designed to be cast so that there will be no center seam that is so common on vinyl tires from 1/24 - 1/25 scale kits
This is the comment -
"tires to be malformed around the edge of the rim", by

My kit has this as well but only on one side because of where the tires were connected to the sprue. For me this is not a problem because I can assemble with this side facing inside (under the truck).
Also notice CONTINENTAL and CONTITRAC is molded to both sides of all tires
Notice how the Revell tires are molded and packaged in the box vs. the MENG parts
Close up of the Revell tire style and quality
Tread style and quality comparison between MENG and Revell. Size difference is that the Revell pick up is 1/25 and rthe MENG pick up is 1/24
