I've emailed Motoz directly and asked specifically about this application, and will let theis thread know their response, if any.
Worth pointing out though- this is a direct quote from their website:
It's had an overhaul since 2007 and is now 1kg ligher, making it an excellent tyre for adventure bikes and big bore enduro bikes with a 2.5 inch rim used in off road applications.
Sure it is a legit point. My point is too. Empirical evidence has shown that mounting these tires on a 4.25 inch rim will not specifically cause them to fail.
Also, if you look under "Tyre Selection" on the Motoz website is shows a diagram of the 140 Tractionator on a 3.5 inch rim.
