I was just guessing they are retreads... I truely have no idea.... is it not good to air them down real low? oops 

Easy to tell if they are a retread, look for the parting line where the new tread was joined to the old carcuss on the sidewall. Should have some grooving or grinding marks in that area. I don't think that cheap car retread makers are retreading the sidewall like a good retreaded truck tire is.

As I did not check the web site of the retread company, I do not know how the tires are done. If the side wall is redone, I don't think that they can mold another companys name back onto it.

Can I air these tires down?
Airing the tires down will void any warranty, however, JP Magazine tested our 31x10.50R15 aired down without any problem and many of our customers do this without any problems. The tires will perform like a new tire.

I'm not an expert, but here's my opinion on it:
1) If they're so confident airing down won't blow out the tire, why does it void the warranty?
2) I don't particularly trust marketing from any company. If JP Mag tested their tires, where's the link to the article?
3) The sites I have read about re-treading say proper tire pressure is ESPECIALLY critical with re-treds, as the area where the new tread & old casing bond can't handle the stress of under inflation. The bond also is more sensitive to the extra heat generated by an under inflated tire. Admittedly - there may be new bonding technologies that can handle it but, here's one source of data:

I don't know to much more about them I have considered trying them but I want the Trexus MT for lil Suzy. They seem to have a lot of positive testimonials on the site from satisfied customers.

I hear you can't go wrong with Trexus MT, or TSL. I'm considering Trexus MT 'cause I hear they're better in snow & ice than the TSL. Hard to find real good data on tires - which is a shame considering it's what's responsible for traction. Not sure why there's not more good articles on tires....

Again, I run the High-Tec retreads and haven't had any problem.  This is daily driving and wheeling occasionally.  I haven't aired them down at all yet.  I run 20-25 psi in them on the street.  Haven't had any problems out of them.  A friend of mine did run their 33" D-Mud w/spacer and had issues with 2 or them bubbling.  He sent all four back and they refunded his money I believe.  Someone else on here used to run the OTRs on their track/kick and wheeled them and had no problems.  That was the reason I went ahead and got them.  For ~$60, I'm definitely not complaining.  If I wheeled on a reg basis and planned on airing down, I'd probably run a new tire though.  Just my .01.

Can you order the retreads with the carcass you want or are you stuck with what you get? Just thinking a Bfg sidewall maybe a bit stiffer aired down than a Michelin.

As I understand it The reason that they only use michelin and some others is because many manufacturers have cheapened the manufacture of their tires and on many by the time the tires are worn out the belts are also. Only a few manufacturers are still using quality belts.

I would not worry to much about stiff sidewalls if you are running a Sami or Kick. With all the air out of my boggers the tire will not go flat. If you are worried about slicing a sidewall on a rock or something these tires are not for you.

Isn't the light weight of the Zuki great? I myself have changed the way I think about tire PSI when it comes to my Sammy. The swampers I have I run any where from 3 to 5 psi and they barely look low at that psi. They are radials so I am sure a bias ply will be even stiffer.

I live in Northern Connecticut and we had 13 inches last week. i tried to go snow wheelin but i kept getting stuck due to stock ride height the skids were making piles infront of the sami and i broke another brake line. 1 am with a hand come along.... stinks with a cruise the next day. haha
