BangTheory Simple Car Snow Chain Tire Chain (Set of 10 Chain) Easy Installation (M size Spike part (yellow part) about 37cm Total length about 83cm Fits tire width 185-225)

Disappointing, the idea of snow tire straps is commendable, but the execution by this manufacturer is poor. The instructions are in Chinese, and although it looks simple to install, you have to know how to install them correctly to avoid the straps from moving back and forth around the tier, also to avoid the metal buckle from scratching your rims. These straps scratched my rims, my new car's also rims, TERRIBLE!!!!!. Also, dont expect to go more than 20 mph, at this speed my new car rattle too much for comfort. If you live in an area like me were the roads are ok a day after a major 'snow EVENT', LIKE THE Blizzard on Jan. 2015 in Northeast US, these are ok for getting you unstuck or preventing you from getting stuck. I have a rear wheel drive car, so i got them just in case i get stuck, however, due the Chinese instructions fiasco and getting my rims scratched, i am going to return these.
