No components to keep mounted on the wheel over winter: just install the K-Summit whenever needed. Innovative design complements the latest car models. Color-coded parts allow for easy installation. Features zero clearance: K-Summit family offers 0 millimeter internal clearance and is the perfect solution for vehicles that have space problems between the wheel and its inner side (behind the tire). Suitable for most passenger vehicles – 0 millimeter clearance behind the wheel. The exclusive ratchet system permits an effortless installation – just one hand required. Ergonomically designed installation handle, just one movement, with one hand. Exclusive steel tensioning springs, decreasing dynamic elevation and enabling perfect fitting on several tire sizes. It features high resistance plastic plates hardened with the injection of steel studs for increased traction, five, foldable arms that collapse for easy storage in the included bag and welded bars providing higher grip and performance on ice and snow. Exclusive 3-step mounting system: Step one: put two of the plastic plates over the tire and adjust the chain laying on the upper tire tread. Step two: attach the chain to one of the wheel’s nut/bolt. Step three: activate ratchet system to make the chain progress toward the rim. The chain will slip automatically on the tire with the wheel rotation. The packaging is exclusive, stylish, hard-sided packaging, complete with gloves, kneeling mat, mounting instructions and spare parts.

The good news is that these chains actually DO self-adjust onto the tire - ONCE YOU GET THE SIZE CORRECTLY ADJUSTED. The pictorial guide had me remove 4 of the cross bolts, and I had to remove one more because I have "mud and snow" tires. MAKE SURE you get these sized and adjusted BEFORE you get to the snow. I would hate to have to try to do this in the cold and snow on the side of the road.

The bad news is that the ratchet mechanism is too flimsy, and you can EASILY damage it by over-tightening while ratcheting in the chains. So be careful.

Note to Thule: If you had actually used words in your instructions (instead of cryptic and hard-to-understand pictorials) I might have avoided this problem. In this case, a couple of words (e.g., "Do not over-tighten the ratchet, because we used a flimsy design") would have been worth a thousand pictures.

Also - the pictorial instructions on how to select the correct stand-offs for the lug nut bolt were VERY difficult to understand. No indications of what the critical spacing or dimensions are, so you have to guess.

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 break and needed replacement, so I began looking for an alternative. These chains by Thule seem to be a great alternative so far.

I have a 2006 Saturn Vue AWD. I'll admit that fitting these chains the first time was a little tricky, but I was having to unlearn what I was expecting from the Spikes-Spiders. They did fall off the first time I used them, but I realized I had reversed a component while trying to make sure I had the right lug adapter on, so it wasn't a fault of engineering but a simple mistake that was easily corrected ...while I was halfway up my mountain. You can't fix an adjustment to regular tire chains unless your car is completely level, which mine most certainly was not.

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 ([...] 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 of my car (Infiniti I-30t). This should not be a problem for most cars. Amazon quickly allowed return/refund. Thule sent me to an authorized local dealer for a fit for their CS-10's which do not require a lug lock, but will require me to be on the ground in the slush to mount and dismount.

I would have loved to have kept these. I guess it is too much to expect Thule to have researched all the kinds of wheels on the market.

I bought this set as it is the only model that fits my 2011 Ford Explorer Limited.

For a year I was able to use these on occasional trips to the mountains, until one fell off my car while driving. I followed the instructions for installation. Drove a couple of miles - less than 25mph. I arrived at my destination and found that I'd lost one of the chains. Very annoying.

Considering my choice is so limited I was contemplating buying another set. I figured that if I lose one again, at least I'll have have two remaining chains to form a new set. However, I see these are now $700!!! Considering I'm not the only person that has lost a pair of these, they do not have the track record to be worthy of such a high price. Beware!

I bought these chains, feeling apprehensive about the price, and unsure whether I even need chains on my Audi allroad (tire size 225/65 R17). As it turned out during the Christmas skiing trip even with good M+S tires and quattro drive you can encounter road conditions that call for chains to be safe. 30 miles of solid iced-over snow, encountering 8 spun-out vehicles and one horrible accident, I was very happy to have spent the money. So half-way into the ordeal, we found a spot to pull over, mounted the chains and were really happy from there on. I mounted the chains twice so far. It is very easy to do, takes 5 minutes on each side, taking them off takes 2 minutes. They drive great, due to the continuous line of chain links along the circumference of the wheel. They don't rattle the car as much as the diamond shaped regular chains do. Driving on pavement feels very smooth. I have not tested whether they would come off in hard cornering and stayed at the 35 mph range, but their advantage of fitting into the complex and narrow wheel assembly, without requiring special rims and narrower tires to make room for full chains is a real boon.
Instructions are not the greatest but not complicated either (Thule has a youtube video showing the installation.) Check the lug nut size and order the very large adapter if you need it. My chains came with an adapter but the standard size fits my car. And fit the chains and put them on at home on pavement to make sure you know what you are doing when it gets dicey!
I can't say how long-lived these chains will be, if you have enough room in your wheel well, perhaps full chains are more affordable, sturdier and even more reliable, but the K-summit are a great compromise.
