Tires connect your bike to the road or trail. So, it's no surprise that optimized tire pressure directly enhances your comfort, rolling resistance, and speed. The Quarq TyreWiz 2.0 is redesigned for accuracy and greater compatibility for differing rim depths to provide precise pressure data in real-time for your best ride.
Lightweight and durable, TyreWiz 2.0 utilizes LED lights to indicate when tire pressure is outside of the target range with an alert for low or high tire pressure.
TyreWiz 2.0 also interfaces with the SRAM AXS app to provide personalized tire pressure recommendations. With a universal rim adaptor and multiple valve lengths, the device sits flat on road or MTB rims. With the standard hand pump measuring at only +/-5% accuracy, TyreWiz 2.0 eliminates barriers by taking the guesswork out of tire pressure to make you faster.

I've been a fan of Tyrewiz ever since they first came out, because it helps me keep tabs on my tire pressure and keep it all very consistent. Sometimes I'd feel the rear of the bike step out just a hair. In the past I'd stop and give the rear tire a pinch to make sure I'm not imagining things. With Tyrewiz, I just glance at my cyclecomputer and keep rolling, no big deal. It was also fun and educational to see my tire pressures go up about 1 psi as they warmed up riding in the sun.
Like another reviewer, I have mixed feelings about this 2.0 model. For starters, the price is very high and on top of that you have to measure your and buy special valve stems. Those valves are a significant extra cost, can be difficult to find (I waited for months in one case) and you need to use a special tool when you're adding sealant through the valve stem.
Also, the battery is unchanged. This is a big miss, because the old battery never lasted long enough on the 1.0 model. If you have just one bike, maybe no big deal, but if you have a few it feels like you're constantly swapping them out. I really wish they would have taken the opportunity to switch to a longer-lived battery. At least the batteries are easier to change than before (see below).
Depending on what rim you have, getting these to sit nicely might be a challenge. Some rims (like the Light Bicycle AM930S) have rippled internal diameters. If you have one of these rims, you'll need to make a run to the hardware store to buy some rubber washers to fill the valley between spoke holes.
Cyclecomputer support is still kind of hit and miss. Garmins only support Tyrewiz through the ConnectIQ app. This app used to be extremely flaky. It seems to be working better now, but I'd like to see real factory support from SRAM on this. On Hammerhead Karoo, the support is quite good, but you have to consume a whole data field for each tire. I'd really prefer to see one field service both tires simultaneously.
I'm also concerned whether the protocol and pairing will work correctly if other Tyrewiz riders are in the vicinity. Rumor has it you might pick up someone else's tire pressures, which would be incredibly annoying.
On the positive side, this form factor seems far more robust than the goofy "flag" style from the 1.0 product. I actually had the flag rotate once and snag on something while descending a flight of stairs, breaking the valve and causing an instant flat. Not cool. This isn't an issue at all on the 2.0 product.
The 1.0 product was really fiddly the change batteries, and the battery contact points were also super fiddly. I used to have to frequently use a jeweler's screwdriver to gently bend the contacts so they'd keep the battery connection alive. Knock on wood, the 2.0 version is very easy to change batteries and the contacts are working better.
As another reviewer noted, one downside of the 2.0 form factor is that using tubes with these is out of the question. I never tried tubes with the old version, but given the "flag" form factor, they should work fine.
Overall, these Tyrewiz 2.0's are better than the 1.0 versions, but they're more expensive and not as much better as I hoped for. The value proposition is kind of meh, so I'd only recommend these to someone who really wants live telemetry of their tire pressures.
First, and most importantly, you will need to measure your wheels rim depth and then order the appropriate sized valves which are needed to make this product work. Those valves are ~$40 a set. If you have different sized rims front to back, you would need two sets of valves. Also, quite a few sizes of valves are out of stock, so check first.
Second, even with the correct sized valves, it's hard to get these valves to seal. They say that the top nut only needs to be finger tight, but despite double checking everything, mine needed to be screwed down with pliers to make them seal,otherwise air just leaks from the bottom of them. That means, you need to carry a small set of pliers on your rides if you ever need to remove them to install an inner tube! If you remove a tire, it seems that it loses its seal and you need to play around with the top nut again to find the perfect point that it does not leak.
Third, if you get past the first two items, these only connect to your Gammin headunit via the Tyrewiz connect IQ app. That's fine, but I have found that if I am riding with other riders who are also using Tyrewiz sensors, we get cross talk where I pick up their tire readings on my headunit and vice versa. The only fix is to get your bike out of BT range of their bike and reboot your Garmin. Thankfully Garmin can do that without losing your current ride stats.
Fourth, when everything is working, it's absolutely great. Riding with your tire pressures showing is incredibly reassuring, especially on fast descents. Knowing you are not imagining a puncture could save a crash. For all the negatives posted above which I now khow to resolve, I love them. Just be warned though - they are not plug and play.
Sure beats having to pull out a gage to check pressure before and doing a trail ride. A bit tricky to install if you are using tire inserts but all you have to do is cut out some material in the Cushcore so that air can get to the TyreWiz.
