I have not used either of those tires you mentioned but have had a set of 32x10.50/15 TSL radials on my Zuki for the last ten years. They started out on my '42 flat fender. Sold the jeep, kept the tire's.
As our toys only weigh around 1500lb's, any tire should last for dang near forever.
In fact, my swampers will be changed out this spring for some boggers. They still have some good tread left, but afrer 10yr's they do have some cracking in the rubber.
I can't complain. 10yr's of use and abuse and the tires still have a good amount of tread left.
I am only changing to the 33' Boggers as I will be putting TT's wrangler spring conversion on this summer.
Lookin' like some good phun here soon.
