I would imagine these are not street legal though. I guess you would either have to trailer your vehicle or find a way of changing them at the trailhead (talk about a pain).
i wouldnt be tempted... id just do it!
if it wasnt so dam expensive to get a set, then i would definitely do it. but there are a couple guys on pirate4x4 that have created homemade track systems
I like the idea and they look great on atv's and rhinos but they only have a top speed of 40mph for the 4runner application. If i needed a 5 passenger vehicle with tracks, i would probably get a snow cat cuz $$ would probably not be an issue!! Personally i would get a Polaris 800 PRO-RMK 163 for snow and a turbo sand rail for the dunes!
