I'd think front runners would work OK.
IIRC when I talked to M&H about mine, they told me not quite... but I've got about 3200 lbs on the fronts ~ 1600 lbs each. on a 5000+ lb total.
At 1375 each or 2750 total on the front's now that sounds more workable.

isnt the m&h load rating only in the 900 lb range? i was just looking at these the other day.

I called m&h tire co. And spoke with John and he said the load rating is 1320lbs for that tire
