Our friends at Sim Works have been hard at work expanding their Yummy line of tires. Included in the mix are these 27.5 x 2.22″ SUPER Yummy gumwall tires by Panaracer. These are fat. So fat you might not be able to clear them, but if you can run a 45mm 700c tire, they should fit. Pictured is my Sklar with an ENVE Gravel fork, which is probably enough clearance for a dry climate bike, but you might run into issues with mud. There is exactly 1/4″ on either side of the tire and fork for reference on the ENVE G series rims. They measure exactly 2.22″ from knob to knob.

Expect a more in-depth look at this bike with the wheels and tires but for now, all I can say is what a massive improvement in traction off road and rolling resistance on pavement with these tires. I think I found my ideal summer tire. In stock now at Sim Works. If you have pressing questions that can’t wait for next week’s review, drop them in the comments…
