Review: Impressive - 38mm - Love the upgrade. 28 -> 40 mm. Over 400 miles so far -about 80% pavement, 20% gravel. Haven't tried other gravel 40mm tires, so can't compare to those. Pros: -Much more comfortable! Can ride lower pressure than 28 mm. Pavement cracks and gravel bumps are way less noticeable. Usually do ~55 psi pavement and ~40 on gravel -Tread. Originally got this tire due to reviews on pavement performance. Rolling resistance is barely increased, if it is even there! After hundreds of miles, the rear knobs are slightly worn; have way over half the life left. Still plenty of grip. -Noise. Slightly louder than slicks, but not by much. Was expecting more noise. Cons: - hard to put on rims, no biggy though - some reviewers mentioned softness of rubber. Can't comment too much on it, haven't had any major cuts or punctures. Guess the SK+ rating works... - Does flick up more dirt and water. Since it has a small tread, only small particles are picked up. Would recommend frame protection and/or fenders. Overall, a better ride, good grip, and long lasting. Will have to see how long the tread lasts! UPDATE: JUNE, 2023 About time.... rear tread is mostly gone, so time to replace soon. Tires have held up tremendously the past couple of years. Still no flats! I run a heavy touring butyl tube with Stan's sealant inside. There are several cuts and holes in the tire from running over things, but holding up well. These things have traveled! I found about 45 PSI to be the sweet spot on the road and about 38 on gravel. Don't know why I was running 50+ from my initial review. Review: A great tire for road, gravel and hard trails riding - I bought the 700x38 tan-and-black, which looks very classy and trendy on my gravel bike. Tire width is 38.1mm (both) once installed. I ride them at 45-50 psi, on both roads and hard trails, and have been very satisfied with comfort, efficiency and stability. Plus they appear to provide little rolling resistance (especially on the road) which is of course always appreciated. Contrary to other gravel tires, this one maintain a roundish look (between the sidewalls) as it doesn't have larger knobbies sticking out on the sides. This means a smooth transition from an up-right to a slanted (when turning) position. But it could also mean less grip while riding off-road, although not a problem on gravel and hard trails. I observed that the thread pattern in the center tends to hold on to small rocks and debris, which can be concerning regarding piercing through the casing. I haven't ridden them enough to comment on longevity and puncture resistance. But I do check them and remove debris after riding them, which is a bit more maintenance that I'd like. The installation was fair (on tubeless rims), although this varies (sometimes substantially) depending on the rims themselves and whether they are mounted with tubes or tubeless. No issues thus far. A great tire for road, gravel and hard trails riding. 5/17/2021 Update: a tiny piece a glass made its way through the center of the front tire, between some of the small square knobbies, and punctured the tube as well. At that time I went ahead with new wheels and mounted them tubeless (quite easily, without tools) , after using a patch to seal the puncture. I ride them at 42-44 psi and they roll very smoothly. ## Features - Panaracer Gravel King SK+ - 27.5x1.90 (650Bx48), Tubeless - Black - RF650B48-GKSK-P-B ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QMTQKG1 | | Best Sellers Rank | #274,888 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #1,684 in Bike Tires | | Bike Type | Gravel Bike | | Brand | Panaracer | | Brand Name | Panaracer | | Color | Black | | Customer Reviews | 4.6 out of 5 stars 392 Reviews | | Global Trade Identification Number | 04931253018404 | | Included Components | Tire | | Item Diameter | 70 centimeters | | Item Type Name | Bicycle Tire | | Item Weight | 1.3 pounds | | Item Width | 1.9 inches | | Manufacturer | Panaracer Corp | | Manufacturer Part Number | RF650B48-GKSK-P-B | | Material Type | Rubber | | Model Number | PANA-GK-SK | | Number of Items | 1 | | Number of Packs | 1 | | Size | 584 x 48mm | | Tensile Strength | 60 psi | | Tire Type | Clincher | | Tread Type | Knobby | | Unit Count | 1 Count | | Warranty Description | Limited | | Warranty Type | No Warranty | | Wheel Size | 27.5 inches | ## Product Details - **Bike Type:** Gravel Bike - **Brand:** Panaracer - **Global Trade Identification Number:** 04931253018404 - **Item Diameter:** 70 centimeters - **Item Width:** 1.9 inches - **Material:** Rubber - **Tensile Strength:** 60 psi - **Tire Type:** Clincher - **Warranty Type:** No Warranty - **Wheel Size:** 27.5 inches ## Images ![Panaracer GravelKing Slick Folding Gravel Tires - Image 1](https://m.media-amazon.com/images/I/71E8zU3s02L.jpg) ![Panaracer GravelKing Slick Folding Gravel Tires - Image 2](https://m.media-amazon.com/images/I/710nERlLcHL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Questions & Answers **Q: In looking at the 1st and 3rd stock photos, the tread pattern does not match.

Very good balance between low rolling resistance while still being very resistant to flats. I just ran these tires in 38s and tubeless at Gravel Unbound 2022 in the Flint Hills of Kansas (second photo) and they didn't disappoint. For those not familiar with this event, it is known to be very hard on tires. Course includes sharp rocks, creek crossings, and this year quite a bit of mud. These tires performed flawlessly. The only negative I had with these is that they were fairly difficult to get the bead mounted on the rim with a tubeless set up. I have mounted several different brands of tires and this was the most difficult. I ended up having to manually mount the bead with tire levers as much as I could and then blast it with the air compressor. Most other tires I have mounted tubeless could be mounted with the air compressor alone. That being said, it was worth the effort as these are now my go to gravel tire. I am comfortable running these as low as 28 PSI in a tubeless setup although I usually run 32 on the rear and 30 on the front. ## Frequently Bought Together - Panaracer GravelKing Slick Folding Gravel Tires - Stan's NoTubes Tire Sealant --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/153218400-panaracer-gravelking-slick-folding-gravel-tires](https://www.desertcart.jp/products/153218400-panaracer-gravelking-slick-folding-gravel-tires) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-18*
