I think I've asked this in the past, but I don't recall ever getting an answer. There are a few people on this forum who have had, or have Acty Crawlers... Removing and re-installing the tracks is a PITA. I don't see a smart way to do it. There is no link in the track, and no way to loosen the tension. This means its a wheel stud stripping extravaganza when re-installing the tracks. Using a crowbar, and alot of cursing, I'm able to get them on. Just seems odd there is no tension system, cause mine seem loose...but of course, I'm never going to find replacements. I even tried contacting OTSU and they told me to fly a kite, or at least the NA division (that is the name brand that is stamped in the tracks) I guess OTSU does not sell tires in North America anymore, and I did not get a reply from the JDM division. Any advice is appreciated!
