I've been looking around for tracks for the better part of the year and i think i have a good idea of what works best. Open tracks with optional extentions for deep snow seem to be the best thing since sliced bread. A friend of mine got these with an 1991 argo magnum he bought a few years back. He had never used them as they ran way too rough. (not hard to figure out why, there is way too much gap between the angles) So i bought them off of him for 150$ and i bought 80 feet of steel angle matching the originals. I am modifying the existing guides and will be putting in the stock argo ones to the angles that i add. eventually i will replace all of them but my budget is limited this year. i'm cutting out the center of the belt so the tracks will run open like escargos or adairs. my question is since i am cutting out the strap in the middle i'm making the tracks 1/2 inch longer right? and in turn i should shorten them a bit? they are already a bit long. i was thinking of measuring all my tires and placing them all accordingly to run tracks then inflating them to the psi i need to run the tracks. i would then measure the total length to go around all tires with a string and adding 1 inch.
