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
