Product Description

Super Z6 was designed by SCC for cars, trucks, and SUV's with restricted clearance around the drive tires. Based on SCC's experience with other products in the "Z" family, Super Z6 has one very special quality: it will operate in less than half of the space required by most cable chains and tire chains. Super Z6 requires only 6mm (1/4") of sidewall clearance to operate. The diagonal pattern provides constant traction, aggressive starting, stopping, cornering and ensures compatibility on vehicles equipped with traction control and electronically monitored brake systems. Traction coils, made from alloy steel are more durable than conventional tire or cable chains. A split outside cable with two fastening positions allows for easy installation without moving the vehicle, and there's no need to stop and retighten. Most cars, trucks and SUV's manufactured since the late 80's will have special clearance requirements. Don't be fooled by the appearance of the tire positioning on your vehicle. Traction products not only have to fit the tire, but must also fit within the space provided around the tires. Most issues are hidden from view as they are behind the tire near braces, suspension parts, strut housings, splash guards and fuel and brake lines. More information should be located in the owner's manual under chains, traction devices, tires or similar heading. It is important to select a traction product that is compatible with the minimum class assigned to your vehicle. The class assigned to your vehicle is based on the original tire and wheel size shown in your owner's manual. Using a different size tire may affect the chain's ability to operate properly. Some owner's manuals state that certain tire sizes do not provide enough clearnace to accommmodate winter traction products. The fact is, many of these vehicles can use SCC's Super Z6. Trying to measure the nearest obstruction under your vehicle could prove tricky.

The unique design also offers a low potential for damage to vehicle body and mechanical components, even when abused.

The Super Z6 SZ139 is designed for tires sized from approximately 195 to 335 millimeters. Check the manufacturer's website for the exact product to fit your tire size. Also check your owner's manual for clearance specifications before installing winter traction products.

Awesome Product
Bought these for my rear-wheel drive Dodge Magnum here in Portland Ory-gun. Stock tires are not setup for snow and rear-wheel drive is a bit trickier in slick conditions with a lot of horses under the hood. So I bought these chains "just in case." Today we had a snowstorm, cars slipping and sliding all over and I wanted to get home. Put on these chains, bit of a struggle to get them all locked in place, and headed out. No problems at all. Passed a lot of cars stuck against curbs or unable to move. The last dragon I had to slay was the big steep hill to the house. Pointed the car up and just kept it pointed straight. Right up with no troubles, maybe a little bit of micro-fish tailing, but the grip these chains gave me worked like a champ. One hint that I discovered, buy a set of gloves to store in the bag with the chains, I did not have any with me and had to hop in the car a few times to get my fingers warmed back up. The little plastic ones they put in there are worthless against cold and snow while you are hooking the chains up.

Good for tight clearances
First off, I don't know jack about tire chains. I live where there isn't any snow and would like to keep it that way. The only time I've driven in snow has been with a 4x4 truck over short distances.

That said, we've got a minivan now and are heading up to the mountains. In the great state of California, you are required to carry chains if you are going anywhere it might snow.

Our Toyota Sienna XLE has 17" wheels and 60 series tires (on a minivan? OK, now it's cool because it has 17" alloys... Oh please!) Anyway I was very concerned about the 60 series tires not having enough rubber for the chains to fit without scratching up the wheels. In addition there is only about a thumbs-width between the tire and the strut (using calipers, I determined that my thumb is 0.723" thick). These are brand new tires so this is probably worst-case. Also, this van has traction control, stability control and ABS which can all be confused by tire chains that slip and grab.

I test fit these and they exceeded my expectations. They are easy to install (I used the instructions, but I'm just that way). They don't come anywhere near scratching the wheels and they clear suspension with no problems. I don't look forward to installing them in the snow and cold, but if it comes to that I feel these will do a good job. The diagonal pattern should do a good job of maintaining relatively consistent traction so the electronics (ABS etc.) don't get confused. Construction looked robust and consistent. On top of all that, the bag was smaller than I expected and I was able to get everything back in after my test-fit.

Hopefully these and the spare tire will never be used, but they'll both be there if needed.

Excellent chains for BMW X3
After a lot of online searching and review reading, I decided on these chains for our new 2007 BMW X3. They fit perfectly, and work just as well. Very high quality product and packaging. I would recommend these to any BMW X3 owners.
