Tales from My Little Mountain
First I would like to say that for those of you suggesting I get "real tire chains"... I have 2 pair that I've managed to get onto my tires exactly... never. If you'd like to buy 2 pair of 17" snow chains cheap just leave me a message, you can have 'em. "Real tire chains" might be great for some people, but if I can't get them on and off my car quickly and easily, they are useless to me.I live 1400 feet up a 2 and a half mile dirt/gravel road that stays ice and snow covered for weeks after there is no snow anywhere else in our county. I am a small business owner, so if I can't get to work, I don't get paid, simple as that. I needed a product that was easy for a 40+ year old woman to get on and off by herself 6 days a week.For the last 3 winters I have been using Spikes-Spiders, which I actually think is a fairly good product as well, but after being put thru the rigors of mountain life, many of the plastic components of the Spikes-Spiders were beginning to...

Product Description
The K-Summit is the ultimate snow chain on the market today. The K-Summit is uniquely designed to ride on only the external surfaces of the tire so you don't need to worry about clearance issues on the inside of the tire or interference with ABS braking, suspension or steering components. The K-Summit is also one of the easiest chains to install in three easy steps. You simply lay the chain on the tire, attach it to one of the bolts, activate the ratchet and you're done. The chain automatically self-tightens and self-centers itself as you drive away. You don't need to keep other components mounted to the wheel over the winter like other chains. The K-Summit was produced in Italy and the craftsmanship and attention to detail are evident. It is made of special alloy plates and strengthening ribs along with zinc-plated pins and hard metal core rivets all designed for maximum grip, endurance, reliability and resistance to abrasion and laceration. The geometric design of the arms and the high toughness of the material won't allow the chain to come off the tire, even in extreme conditions. In addition the innovative ratchet system has a force multiplier of nine times so it allows effortless fitting and a safety lever to avoid accidental openings. Top to learn more

Superior Engineering and Design
Thule snow chains are hand-made in Italy and are constructed of durable, hardened Manganese Nickel Alloy Steel. This type of steel has a tight molecular structure that provides added strength in cold conditions. The K-Summit features reduced-clearance, D-shaped links that provide exceptional traction and guarantee long product life. All chain components are meticulously tested and measured to ensure an exact fit that will not damage critical wheel components. K-Summit snow chains utilize a steel spring system that automatically adjusts itself for a perfect fit, even through varying degrees of tire wear. Aerospace plastic plates, zinc-plated steel pins and hardened metal-core rivets have been used throughout the chain to provide maximum durability and safety. Additionally, the color-coded assembly points make mounting easy in all lighting conditions.
Thule K-Summit - The Chain That Goes Where Others Can't
Thule has specially designed the K-Summit to fit a wide variety of passenger tires and wheel applications. Not only are they well-suited to standard passenger vehicles, they also fit specialty and customized vehicles that have very tight wheel tolerances. Its components have been constructed to provide excellent snow and ice traction, all while keeping mechanical components, electronic devices and the vehicle's body free from chain interference or damage. K-Summit chains are easy to install and don't require any components to be permanently mounted on the wheel during winter months. The quick, 3-step process minimizes the amount of time you're exposed to the elements. To install the chain, simply lay two of the traction plates on the tire tread, attach the central unit to one lug nut with the included ergonomic tool, and activate the ratchet system. The chain will automatically self-adjust and tighten as you drive away. High-strength materials and an advanced geometric design keep the chain from slipping off of the tire, even in extreme conditions. K-Summit snow chains include 17mm and 19mm lug nut adapters, and 21mm adapters are available on request.

How to Choose a Snow Chain that Fits Perfectly
To choose the right snow chain you must follow a few simple criteria. First, check your vehicle’s maintenance or owner’s manual to verify it contains no warnings advising against the fitting of snow chains on your particular vehicle. Once verified, take careful note of the three measurements on the side of the tire. The first number indicates the width, the second gives you the aspect ratio (sidewall height as percentage of width) and the third denotes the diameter of the wheel expressed in inches. Then click on the Thule K-Summit Snow Chain Fitment Guide to choose the most suitable model and size for your vehicle.

Excellent Engineering, but did not fit my wheels
I couldn't wait to get these, given Seattle's unexpected week of ice. The chains fit several tire sizes with clear instructions for removing 0 - 4 sizing clips for each size (all four for my 225/50-R17). These are as easy on/off as this video shows (http://www.youtube.com/watch?v=opugSM6xs58). No need to get knees wet, or lay on the ground.The chains ride only on the tread and not on the back of the wheel/tire, requiring no inside clearance. The thin cable chains add only about 10mm to the top clearance. The ice grips are aggressive and the chain angles will provide lateral slide resistance.The set came with the tools needed to remove the clips and mount the lugs. The clips are put on from the factory with something like "Lock-tite". Recommend a 7mm socket to replace the wrench and your own good set of metric Allen wrenches (3mm).Only problem was the lug locking mechanism was too shallow to fit my deeply recessed lugs on the standard wheels...

Works as advertised, but check your lugnut/bolt size
The K-22s work just as advertised. It takes a little extra effort the first time or two, but once you get used to the system, these are the easiest chains to put on you'll ever own. The traction seems VERY good, and the chains tighten around the tire perfectly. It almost feels like they are part of the tire (which means them off sometimes takes a little effort - just be sure you have some gloves you don't mind getting a bit dirty)I drive a car with 21mm lugnuts. These ship with 17 and 19mm fittings, so be sure that if you have a car with larger lugnuts you get the adapter. (Prius owners, this means you). They are available from [...] if Amazon is sold out.I haven't had these for very long, but they seem to be very high quality. The warranty is 1 year, but I would expect them to last much longer. And yes, the price is a little high, but it is a lot less than the cost of damage rims and certainly a lot less than internal damage to your cars braking mechanisms or...
