Sorry SOCAL. I dont remember the thread but I am a Snow Trac guy who dabbs in Thiokols. OK so I own a bunch but no 601s. Try dropping a PM to MAINERD. I bet he knows where to find them.
Rubber is easy to find too ... there were a few threads that rubber was tricky. If you have any issues sourcing the tires let me know.
might as well give me those too. also,,,is there any other companies out there, beside fallline that do the filling of tires? what are they filled with, and should i be able to find a tire company out here in so-cal that could do it? how many tires should i get filled?
SoCal,
Get all of your tires filled. Superflex or Polyurethane. Get medium density as well. For your two spares you will buy (should) get those done at the same time. Get the best tires (6 to 8 ply or higher) you can find. This combo will last you a VERY LONG time and you wont have any flat tires to deal with in the field. TRUST me you dont want to be changing tires in field conditions! One of my tires which was poly filled was a 4 ply tire. The tire itself came apart! NEVER EVER go with anything under a 6 ply tire! Why the previous owner spent the time and money to have the tire poly filled but used the absolute cheapest tire available is beyond me! Its pricey but its one of those components that are so critical to get you back home.
