HUTCHINSON Override 700x38 Tubeless Ready Black Bike Tires, 700cm x 38/40

I live in dead-central WA state with lots of goathead thorns. I followed the saga of the TransAm bike race from Portland OR to the Atlantic coast a couple of years ago when Lael Wilcox of Anchorage won the race on tubeless Hutchinson Sector 28mm tires. I perked right up, as tubeless road tires were not yet in vogue. The fellow in second place was running innertubes, and he was suffering from multiple flats toward the end of the race.Miss Lael had only one single flat over the whole route -- from riding at night in the dark and going over a broken bottle. She put in an innertube and replaced the tire with a new Hutchinson Sector 28 in Kansas.I was inspired by Lael's feat to install Hutchinson Sector 28s, tubeless, on my Cannondale, the largest tires that particular bike would fit. I set the tires up tubeless with the help of YouTube videos. I like the way they look and ride, and I've never had a flat.Soon after, I was building up an All-City bike for all-road application with only a White Industries single 34T in front. The Whiskey forks on the new All-City will fit very large tires. I was going to run Hutchinson Sector 38s, but the Sectors only go to 32mm, so I am running Hutchinson OverRide 38s, tubeless. So far, I see no disadvantage to myself in running OverRides instead of Sectors.The OverRides have some very light knobs which don't much hit the pavement except when leaned over. For my purposes, they roll as easily as the Sectors. I've not yet had a flat on any Hutchinson tubeless tire -- ever.My 38mm OverRides are mounted on Velocity A-23 rims. My Mitutoyo digital calipers say the tires are an honest 38mm wide. Most tires are more narrow than claimed; these 38 OverRides are not undersized -- at least not on my A-23s. I've been airing them up to 60 or 70 psi, and riding them until they drop to near 30 before airing up again. My impression is that they feel too soft at 30, and they start to feel hard and harsh much above 60 psi. Any place between feels pretty good. Try Hutchinson road tubeless. Lael Wilcox can't be wrong.

This was my first time mounting tubeless tires. They went on very easy on a Stans ZTR ironcross wheelset. Used one lever to assist. Used stans sealant as well. FYI, tire weight for the 700x38 was 434g and 437g. Mounted width is 38.8mm and 38.3mm. Very quiet on asphalt, decent grip in gravel. These replaced a set of Donnely MSO X'plor 700x36. The overide's has a more comfortable ride at 40psi than the Donnely's. Only have about 50 miles on them on the first day. Speed feels the same as the Donnely's. I'll update later.

It's a good fast tire for firmer gravel/hardpack and some pavement, racing or otherwise. It does give some float in the softer gravel, but I would use something wider with more tread for that.

Great for Michigan gravel racing in dry conditions that are not overly loose (hardpack). Ran the 35mm rear w Gravelking SK 35 mm front, and it's a great combo. Do not have a caliper but the Hutchinson is small to accurate, while the SK plumps out about 4mm in the 35mm I have, perhaps newer ones are more true to size. If you tend to climb out of the saddle the 35 may not work well for you, or size up to 38 and play w pressure. The sidewalls feel like they have decent protection, yet the ride is very fast and supple. This is a very special tire. It does look they will wear fast though. A decent tradeoff for a sticky compound. Don't think anything can touch this tire for speed. 35mm rear and 38 front could work well, or a GK SK, Maxis Rambler, Schwalbe G-one front tire. If muddy, snowy, or re-graded roads choose GK SK or similar. Works incredibly well if you stay within it's parameters. Slam dunk for speeds above 18-19 mph in hardpack.

No issues yet. 400 miles of gravel.

Put a lot of miles on a set tubeless without any problems. They are definitely tough. Been through lots of single track, gravel and pavment.
