The Onza Ibex tire is a fast-rolling all-mountain tire, offering plenty of grip for a variety of applications. The taller ramped center knobs allow the tire to get up to speed quickly while still offering plenty of grip on steep and loose descents. Constructed with Onza's RC255a compound, this Ibex tire features a hard 65a durometer rubber down the center tread for fast rolling but a 55a durometer rubber on the side corning knobs for additional traction for railing those corners. Tubeless ready out of the box, you can add some tan-wall bling to your bike without sacrificing the your tubeless setup.

I decided to try out these Onzas after hearing good things about them. WOW! These are arguably the best MTB tires I've ever ridden. Granted, they are designated "FR" for freeride tires but these are more than fast enough for Enduro/AM which is what I use them for. Mated up tubeless (which sealed with a floor pump and zero hassles) they offer incredible, predictable grip and fast rolling. Since they are a grippier, beefier rubber, they will have a bit of a weight penalty over an XC tire but the grip and cushion afforded is well worth it. The shoulder knobs are great for situations where you're on the edge of traction and if they start to slide it's easy to correct. Braking and cornering performance is top notch. These tires really perform well on a wider rim, and beg to be abused and leaned over! however they aren't the fastest rolling due to the softer rubber compound. As far as I know these are some of the only tubeless-compatible skinwall 27.5" tires on them market and they are totally worth it!
PROS: Good Grip, Durable, Supple, Fast Rolling, Tanwall, Easy to set up
Greatest looking and best performing tire I have purchased in a while. Tread wear and life seem to be great. Local trails in Sycamore Canyon and Snow Summit, even in Mammoth these tires perform extremely well.
PROS: Improved Cornering, Old School New School, Attractive Design, Durable
