I don't know if they are a help or not, I finally got them in Feb after bugging the CRAP outta hubby for them, and 6 days later she was hit and now in the body shop. I do know that here in Pittsburgh, we get a sh*tload of snow and we got stuck in the first snowstorm on a huge hill (the whole dammed city is on hills!). Xmas dinner and it started to snow and we had the Z so I told hubby it was time to go b/c of the snow and the z no go in snow. He said Ill drive it home (like he's the expert). So we get going later on with an inch of snow on the roads....first hill, we are stuck. Wheels a spinnin, just spinnin and not going anywhere. Spin spin spin spin spin. He gave up and was going to have some trucker dude pull us up the hill but we didn't have a screwdriver to take off the front plate and use the tow hook. I said move--I am driving, and after about 45 minutes of *inch by inch by inch creeping little gas little gas little gas* we finally made it up this 100 foot hill. It took me 2 hours to drive 12 miles, but I DID IT and not him! LOL Those stock tires are worthless, dangerous, and absolutely hard as rocks in the snow and ice. I just waited to go to work till after they plowed my street, b/c that way I KNEW they had gotten to the bigger roads. I can't get a beater b/c we barely have enough room in our driveway for my Z and his truck. No garage. So $800 in snow tires it was. I wouldn't trust driving on those stockers for anything in the world if you live in an area that has snow for 4 months of the year. IMO
