Boom Racing continues to push the envelope on developing the next generation of extreme performance scale crawling tires. The new 1.9 XS HUSTLER M/TX MC1 does just that. The size is 4.19x1.46 ... and they dubbed it MC1 or Max Class 1. This new tire is based on the HUSTLER M/TX 4.45 design that was released in early 2017.

The new tire has a long name - Boom Racing HUSTLER M/T Xtreme 1.9 4.19x1.46 SNAIL SLIME™ compound Rock Crawler Tires W/ 2-Stage Foams (HUSTLER MC1). The long name is justified by the amount of tire technology all packed into one scale RC tire. While keeping the unique features of the original HUSTLER design, a few additional features can be found on the new HUSTLER MC1: Thicker tire carcass all around to hold the lugs better, giving drivers more control and better predictability. Smaller lugs (approx. 3.3mm) in proportion as compared to the larger 4.45x1.57 tire for traction bite as well as scale looks. Where other mainstream tires might find themselves struggling, the HUSTLER MC1 tire is designed to hook up on the toughest lines and do work for you. The lugs act as little claws and grab onto any surface they come in contact. With these tires there is less chances for drivers to look for alternative drive lines.

A brand new 2-stage open/closed foam is developed and is included with the tires ... Boom Racing continues to deliver "the best bang for the buck" - the new cell foams have a thick closed cell inner foam to maintain tire sidewall strength, and a soft outer open cell foam to let the tire sink into the surface. The HUSTLER MC1 is made for extreme all-around crawling in rocks, mud and sand.

Tire compound used is Boom Racing's trusted proprietary rubber formula SNAIL SLIME™, which is a super sticky compound, providing excellent grip and traction suited for RC crawling. 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.

The aggressive sidewalls give you strong side bite ability. Tread on the outer wall will grab onto ledges and shelves, even slick granite on just the sidewall.

The tire will go through mud like no other with its self clean feature, and rock climbing capabilities is top notch. For example, the spaced out lug design help clear mud and sand out with just a blip of throttle.

Features:
Super sticky SNAIL SLIME ™ compound providing great grip and traction.
Self clean feature for mud, sand and debris out of the tread to prevent caking.
The entire carcass is reinforced on the inside to hold the sidewall and lugs on top.
Very tall and big lugs for a Class 1 tire with deep sipes to grab rocks like gangbusters.
Scale details on the tire like wear bars between the lugs and lots of scale details on the tire face.
Open-cell/closed-cell 2-stage foam prevents the tire from folding under pressure.
The 2-Stage open-cell/closed-cell foam combo provides the perfect factory setting for the HUSTLER tire.
