Well I don't have that size here right now, but my chain supplier lists two different part numbers....one for the 11" wide tire, and another for the 8" wide tire...so that leads me to believe that the set you have won't fit.

And while I don't see your exact tire size listed, I do see where the same part# chains are supposed to fit 25x1000-12 through 25x1350-12....your tire is in the middle of that range, so a set of chains that fit those tires should be what you want...the various manufacturers group their chains together differently sometimes, AND tire chains may well require adaptation....adding or removing links, to get a truly custom fit.

Try for a set that fits a 25x1350-12 tire...you should be able to make them work without too much trouble.

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
