Glacier Tire Chains - PWH2821SC

  • Tire Chains
  • On Road Only
  • Deep Snow
  • Ice
  • Assisted
  • Glacier
  • V-Bar
  • Not Class S Compatible
  • Drive On and Connect
  • Ladder Pattern

The V-bar studs on each cross chain of these heavy-duty, twist-link snow chains bite into frozen roads to give you excellent traction in deep snow and ice. Also ideal for mud. Built-in cam tighteners make fitting and tightening the chains a snap.


Features:

  • Provides excellent traction in deep snow and ice
    • V-Bar-style twist links are studded to bite into surfaces
    • Ladder pattern provides good traction as you drive forward
    • Cross chains are twisted for additional traction
  • Installs easily with integrated, heavy-duty lever
    • Side cams provide effortless tightening - twist cams to pull chain taut around tire
    • Rubber adjusters (sold separately) are recommended for a tight fit
  • Constructed of low-carbon steel for durability
  • Works on either front- or rear-wheel-drive vehicles


Specs:

  • Fits: 15" - 19-1/2" tires (for exact sizes, see below)
  • Quantity: 2 chains
  • 90-Day warranty


Note: To determine whether you can use snow chains on your vehicle, or if chains might affect your ABS/ESP functionality, consult your owner's manual.


These chains are outstanding in serious winter conditions because the V-bar studs can bust through intense ice and packed snow. So, you'll be able to get to work and back home again even in the toughest weather. You can also use them if you ever go off-roading and end up in a mud-digging situation. These chains are going to help give your vehicle purchase to pull out and keep moving.


Confirming Your Fit

If you know your tire size, you may think you won't need to test fit your new snow chains. But there are a lot of variables that can affect whether chains will fit your specific tires, including your tire type, the amount of air pressure in the tire, the amount of tread wear, and the tire manufacturer.


We recommend that you order chains as early in the season as possible to give yourself plenty of time to test fit the chains and reorder if needed. This way, you won't be stuck out in the cold later with snow chains that don't fit.


You can test fit these chains in your garage or driveway, but you'll want to wait until there's snow on the ground to actually drive with them. These will cause damage to your garage floor and paved driveway. If you're out in the snow and come across bare pavement, you'll want to pull over and remove the chains. These can cause damage to your vehicle if they break from the wear of riding on a harsh surface.


Installing Snow Chains

Installing tire chains is easy.


Lay chains on the ground to get all the tangles out

1. Lay out the chains on the ground to make sure there are no twists or kinks.


Cross chain connections should have the prongs facing away from the tire

2. Drape the chains over your tire, ensuring that the v-bar studs face away from the tire.


Connect chains on the back and front of the tire

3. On the back of the tire, pull the chain tight and hook the ends together. Repeat this on the front of the tire, then clamp the lever to fasten extra chain links and keep them from flapping as you drive.


Use tool to tighten cams on the sidewall chains

4. Insert the included tool into the cam and twist to tighten the sidewall chain. Twist as many cams as it takes to get a tight fit.


Rubber adjusters ensure a tight fit

5. Drive forward 2-3 vehicle lengths and recheck the chain tension. Tighten any loose cams. If needed, rubber adjusters (sold separately) can be used to get a tight fit. Make sure the hooks on the adjusters face away from your tire so your wheels don't get scratched.


Quick Tips:

  • Lengthen the life of snow chains by drying them after each use before you store them.
  • Check out our installation kit with safety lights and a kneeling pad (PO34FRK) to make things a little easier when you're installing chains out in the snow.

How to Choose Snow Chains for Your Vehicle

To choose the right snow chain, you must match your tire size. Those measurements can be found on the side of your tire.


Tire size on sidewall

185/60-15

  1. (185) - indicates tire width in millimeters
  2. (60) - gives you the aspect ratio (sidewall height as percentage of width)
  3. (15) - denotes the diameter of the wheel rim in inches

  • V-Bar Snow Chains that Fit LT245/75R16
    The Glacier Tire Chains with Cam Tighteners # PWH2821SC that you referenced is a confirmed fit for the LT245/75R16 tire size you have and because of that would not require taking any measurements. Due to how the chains fit on tires there really isn't a good way to measure them to determine what size tire they would fit so relying on fit info from manufacturer is best option. We do sell replacement cross chains for this with the part # TC6860. For a similar chain to this one that does...

  • Recommended Snow Tire Chains for 30x10.0R14 UTV Tires
    I spoke with my contact at Pewag and Glacier and he said that for your 30x10.0R14 UTV tires the Glacier V-Bar Snow Tire Chains # PWH2821SC should work nicely. These feature V-bar-style links and twisted cross chains for excellent traction in the snow and integrated cam tighteners to pull the chains tight around the tires. I also recommend adding some tensioners like the Titan # TCMA2 to create an even tighter fit. I have attached a short video demonstration that you can also check out.

  • Are V-Bar Snow Tire Chains Available For 30x10x14 Tires?
    For your 30x10x14 tires you will want to go with Glacier V-Bar Snow Tire Chains with Cam Tighteners - 1 Pair # PWH2821SC; Glacier has confirmed these chains fit that tire size. You will also want to use adjusters to keep the chains tight on your tires; for this I recommend Titan Chain Multi-Arm Rubber Tire Chain Adjuster # TCMA2. I attached a couple helpful demonstration videos for you.

  • Snow Tire Chains That Have Ice Cleats and Cam Locks
    There are chains available which will work for you but the Glacier V-Bar # PWH2821SC are not confirmed to fit 265/75-16 tires. Instead you would need the Glacier V-Bar part # PWH2828SC; these are confirmed to fit your 265/75-16 tires and also have ice cleats and cam locks like the chains you referenced. I've added a link to a pair of video reviews on these chains for you to take a look at.

  • Which Tire Chains Will Fit a Tire Size 245/75R16
    Actually, the correct Glacier Snow Tire Chains with Cam Tighteners that you will need is # PWH2821SC. These will fit a 245/75-16 tire. I have included a link to all of the chains we carry that fit your tire size. I have also included a link to our tire chain FAQ article. You will want to take a look at your vehicle owners manual for specifics on tire chain use.

  • Recommended Tire Chains for LT245/75R16 Size Tires on 2004 Chevrolet Silverado 2500 HD
    I found an online owner's manual of your 2004 Chevrolet Silverado 2500 HD and it states to use tire chains on the rear tires only. You should confirm this with your owner's manual just to be sure. Tire chains are not recommended on a trailer since there is not drive axle that will need the traction. There could be some advantage with braking but it's going to be minimal and your truck is going to be the one that needs the traction. A good heavy-duty set of chains for your truck confirmed...

  • What Off-Road Tire Chains with V-Bars do You Recommend for a 35x12.5-17 Tire?
    While we do have some great off-road tire chains with V-bar studs, we do not have any that also have cam tighteners like the # PWH2821SC. This is because all tire chains with cam tighteners are not rated for off-road use due to the construction. However, the lack of cam tighteners will not affect the fitment of the chains as long as the chains are properly tightened. For a great set of V-bar off road chains that fit your 35/12.5-17 tires, I strongly recommend using the Titan Chain Snow...

  • Do Glacier V-Bar Snow Tire Chains Have Cam Tighteners on Both Sides and What is the Chain Size
    The Glacier V-Bar Snow Tire Chains with Cam Tighteners, # PWH2821SC, has cam tighteners just on the front of the chains. In order for the chains to fit properly, you would cinch up each cam and not leave any loose. The chains are 5.95mm thick. I recommend checking your vehicle owners manual to determine if chains can be used and if there are any restrictions. I have included a link to our tire chain FAQ for reference.

  • Recommended Tire Chains For A 285/55R20 Tire Size
    We do not currently carry any V-Bar style tire chains that will fit a 285/55R20 tire size but we do offer three different chains; The Titan Chain Alloy Snow Chains w/ Cams for Wide Base Tires - Ladder Pattern - Square Link - 1 Pair # TC3231SCAM, which is your basic tire chain. It has square links that give excellent traction in the snow plus great grip on ice. Cam tighteners let you quickly adjust the fit for simple installation.

  • Fit of Glacier Chain # PWH2214SC Snow Chains on 245/75/16 Tires
    According to Glacier Chain, the correct size Square Link Snow Tire Chains for a P245/75-16 tire would be part # PWH2821SC. Your existing chains are a little too big to correctly fit your snow tires. You want snow chains to fit as snug to the tires as possible, otherwise steering, suspension or brake components could be damaged. I'd also recommend checking your owner's manual to see if Toyota has any advice or prohibitions regarding the use of tire chains. Some vehicle manufacturers recommend...

  • Tire Chains For Side By Side With 30x10x14 Tires
    I would be happy to recommend tire chains for your side by side with 30x10x14 tires, but you will need to verify the actual diameter of your tires before ordering. The Glacier Mud Service Snow Tire Chains # PWH2433S are a great choice for mud, snow, or ice and will work with 28x8.5x14 or 29x9.5x14 tires. You will also want the Titan Chain Multi-Arm Rubber Tire Chain Adjuster for Passenger Vehicles # TCMA1 to keep the chains snug to your tires. If your tires are actual 30x10x14s you would...

  • Cables or Chains for 30x10R14 Tires on Polaris General
    The Glacier V-Bar Snow Tire Chains with Cam Tighteners # PWH2821SC are quite literally the only chain option that we have (December 2021) for the 30x10R14 tires on your 2018 Polaris General, but even if there were cables available I would recommend going with chains over cables because cables are basically just good for 1 use and will be hard to use multiple times whereas chains like the Glacier V-Bar are heartier and will last longer.

  • V-Bar Tire Chain Recommendation for Tire Size 265/75-16
    I have a similar set of V-bar tire chains that do fit your tire size of 265/75-16 but the part # PWH2821SC is not what you need. Instead you'd want the Titan chains part # TC2828CAM which are a fit and will work great. These have cam tensioners which make them easier to tighten and since they are V-bar chains they are also really great in the ice.

  • Recommended Tire Chains for 2016 Toyota Tacoma SR5
    The factory tire size on your 2016 Toyota Tacoma SR5 is P245/75R16, so the Glacier V-Bar Snow Tire Chains with Cam Tighteners - 1 Pair # PWH2821SC will work very well for your application and uses cam tighteners for a quick and easy installation. Your owners manual states to only use tire chains on the rear tires, so using them on all 4 tires could void your warranty. You also should not exceed 30 mph with them installed.

  • Are Rubber Adjusters Needed On The Glacier V-Bar Snow Tire Chains with Cam Tighteners # PWH2821SC
    The Glacier Rubber Adjusters for Snow Chains, part # PW99, are recommended for use with snow chains that DO NOT include other tensioning devices. The rubber adjusters are attached to the side of the snow chains to keep tension on the snow chains. The Glacier V-Bar Snow Tire Chains with Cam Tighteners, part # PWH2821SC, has cam tighteners that will keep tension on the snow chains. You will not need the rubber adjusters on these snow chains.

  • Using Cam Adjusters in Clacier V-Bar Tire Chains
    Although it cannot be seen in the photo, each adjuster has a small slot in the center that the blade of a large flat head screwdriver would fit into. Once the chains are in place with all 4 adjusters in the open position, you can insert the screwdriver into each slot and twist the adjuster into the closed position. The more adjusters you close, the tighter the chain will be.

  • Advisability of Using Tire Chains on a 2010 Chevy Express
    If the owners manual prohibits the use of tire chains, I cannot make any recommendations that might contradict that. You might check with your Chevy dealer to see if a Class S tire chain or cable would be permissible. A Class S chain will extend no more than 15 mm (some would extend less) to the inside of the tire and would provide maximum clearance. I have linked you to our selection of Class S chains and cables that are compatible with your tire size. The primary differences between...

  • Easy to Install Tire Chains for 2001 Dodge Ram
    I'd recommend the Pewag Snox self-tensioning chains, part # PWSXV580. The chains are extremely easy to install, you just loop them around the tire and drive away. The chains will self-tighten and center as the wheel spins. The square chain link provides excellent traction, and the manganese-nickel alloy steel is very durable. If you click the provided link, you can see how simple the chains are to install. I'll also link you to some FAQ articles about tire chains that you might find helpful.
