Here is a great option for 1.55" tiny tire - HUSTLER M/TX 4.19" Max Class 1. This is the perfect tire size for running Class 1 comps. Aggressive tread pattern with dual-stage open/closed cell foams to maintain sidewall profile. Great for scale builds while giving great performance on the trails.
Background:
The HUSTLER tire series is a top performance RC rock crawling tire designed for extreme rocks, mud and sand. In a short span of time the HUSTLER tire series quickly gained popularity and fans around the world. Top drivers use HUSTLER to compete in RC rock racing and rock crawling events.
Boom Racing's proprietary SNAIL SLIME compound uses an ultra high quality, soft and sticky rubber to gain traction over all terrains. The rubber has good wear characteristics, even with the Super Soft compound, you can use them for extended amount of mileage without noticing much tire wear.
Deep and open sips release dirt, mud and sand with a blip of the throttle. The aggressive sidewall provides strong side bite ability. Tread on the outer wall will grab onto ledges and shelves, even slick granite on just the sidewall.
One of the highlights of this 1.55" MC1 tire is the dual-stage foams. The sidewall is taller compared to the HUSTLER 1.9" MC1 version, thus a beefier sidewall is needed to maintain sidewall profile. The included 2-stage open/closed cell foam provides the perfect factory setting for sidewall strength and to maintain profile that prevents folding.
Compared to the 1.9" MC1 this is 0.08" (2mm) narrower.
