Love these tires for park and street. Nice grip. 2.25 is just right, not to big.

These are excellent all around tires that excel on streets, asphalt and dirt jumps. Loose dirt you may want to get something a little knobbier but dirt jumps that are decently maintained are the primary place I use these along with asphalt pump tracks where they make an awesome whirring/zipping sound.

My measurements are pretty close to advertised for thr 2.25” tire although all 4 of the tires I tested weighed more like 21-21-5 oz.

Great all around tire. Can do anything on these. Park, steet, a bit of trail/dirt.

Absolutely fantastic on a variety of surfaces. I run this in the back and a 2.4 hammerhead in the front. Best tires ever.
