JACO TreadPro Tire Tread Depth Gauge, Dial Type

I own 5 vehicles and decided to purchaes this item to confirm what the mechanic may state as my tire tread condition. This item works well, is well built and feels good on your hands when using...not a cheap feel at all, which sometimes is important for tools. I went with JACO since I own a tire pressure gauge that has been a total workhorse , whihc I have owned for years. This JACO tire tread depth guag e is easy to use and the bright dial with color as measurements decrease was helpful. As soon as the item arrived I measured the tires on all 5 vehicles and it worked perfectly. I also had no issues with calibration. After eash measurement, I simply placed the gauge on a flat surface, or for speed and eas of use, just used my finger to level the plunger so it would read zero after each use. If this product is like my other JACO product, this will last for years and is another great automotive tool to have on hand.

Great product at a great price. Very easy to use and quick. Now I know how much wear there is instead of just guessing.

This is a quality depth gauge that I bought for a friend’s birthday after purchasing a Safelife digital depth gauge on Amazon for myself. Compared to the Safelife digital gauge on Amazon, it has a better weight/feel and build quality. The Safelife gauge has a bottom platform width of 2-3/8” which exceeds the Jaco by almost an inch meaning that for wide tire tread widths, the Jaco needs to be more centered properly over the tread to get a good reading. Other than this feature, the Jaco exceeds the Safelife in every other category. It has an easy to read analog dial with a resolution of 1/128”, and produces more repeatable readings. When I zeroed out the Safelife and then made a measurement then re-zeroed out the gauge it was almost always off by 0.02 mm, which isn’t the end of the world but just comments on the measurement reliability. The analog vs digital reading reminds me of modern car speedometers (digital/analog) and watches. For me, I prefer an analog reading over digital but that’s just me. Seems to me your brain can approximate an analog reading much faster over digital for a specific range and the Jaco is color coded for acceptable tread depths so you don’t need +/- 0.01 mm resolution to determine that your tread depth is within range.

Great tool to have around and an easy way to gauge when to replace tires

I really like this guage. It seems well built and feels very solid in the hands. Accuracy seems to be spot on, and I like that it is very easy to read as well. I bought, and have used the cheaper ones, which work well, but more difficult to read. The large dial is very easy to read which I like. Also, due to the larger dial, it is much easier to see how close you are getting on treadwear and is a big plus over the small little ones. Handy little pouch as well to protect when sitting in a drawer or in tool case. I will say that it probalby wouldn't stand up well if dropped on the cement (due to glass cover), but not sure I'd trust any good guage if dropped! But it feels solid and is well built. Strongly recommended.

This manual tire tread depth gauge was exactly what we needed for quick tire inspections. My husband is a professional mechanic, and we added this to his tool kit to help spot tire wear patterns during routine checks. For the price, it’s a fantastic tool—but be warned: it’s not built to survive a drop. Before the drop? Flawless. The dial was easy to read, smooth in operation, and accurate. It gave consistent results and made checking tires fast and precise. No batteries to worry about, and it felt solid enough in the hand. We used it on everything from sedans to lifted trucks. After the drop? Not so great. Unfortunately, it slipped off the workbench and hit the garage floor. After that, the dial needle was permanently stuck about ¼ inch forward and wouldn’t return to zero. That threw off all the measurements and made it unreliable. There was no visible damage, but something internal shifted out of alignment. Lesson learned: this tool works great—but handle it gently. It's more of a precision measuring tool than a rugged shop item. If you can avoid dropping it or store it in a secure spot (maybe a small padded pouch or drawer), it’ll serve you well. Pros: ✔️ Accurate, simple, and quick to use ✔️ No batteries or digital parts to fail ✔️ Clear dial display with precise measurements ✔️ Great for home or shop use Cons: ✘ Fragile—dropped once and lost accuracy Final Thoughts: This is a super handy tool that works perfectly—until it takes a fall. I’ll likely buy a replacement, but I’ll be more careful with the next one. Still highly recommend it for anyone doing tire inspections—just don’t treat it like a hammer.

Like it better than the old style ones. Yes a couple times so far. Have found it easy to use. Easy to read.

Easy to use and accurate

Seems to work pretty good. Great quality and easy to read dial. Heavy solid metal housing. 2 inches wide. Pouch good quality too.

Solid easy to read instrument. Very professionnal

Easy peazy depth of thread in a second.
