About the Street Radials Tires
Tread Design
These Street Radials are built to take your on-road performance to the next level. Engineered for action, they're perfect for tearing up streets, parking lots, skate parks, and more. On pavement, rough concrete, or asphalt, they deliver strong traction for wheelies and fast runs, while smooth blacktop lets you pull off slides and impressive burnouts. The wide sipes keep the tires cool and help clear away water, dirt, and debris for consistent performance.
Compound & Construction
Constructed from a tough compound, these tires are designed to be soft enough to provide excellent grip across rough terrain. While being soft and unbelted, they show minimal ballooning on 2S and 3S setups, allowing them to stay flatter and maintain strong traction at higher speeds. Choosing UpGrade RC tire compounds ensures a reliable and exciting bashing experience!
Multi-Spoke Wheels
The multi-spoke wheels are molded from a firm composite that provides strength with just the right amount of flex. This design enhances stability and traction while also absorbing impacts during aggressive driving. With interchangeable hex adapters, including twelve-millimeter narrow, twelve-millimeter wide, and fourteen-millimeter options, these wheels are compatible with a wide range of vehicles and allow for increased track width for added handling and stability characteristics.

First run one battery in, tire blew just running in a parking lot. Super thin rubber, not worth it now I have 3 tires I can't use...waste of money.
Bought these from my local hobby shop. We run asphalt 2s parking lot racing with some jumps. These are awesome till you hit a jump and try to correct on a Mini XRT. The tire grenaded on the first lap and first jump. Super annoyed.
I would give these 5 star if they were belted! Come on, make a belted version! These tires rock. Sized right. Great concrete grip. Useless in grass, but that is not what they are for. Hardpack, concrete, speed, bashing, all great. Just give me a belted version please! My Traxxas Mini XRT spins these up like mad on 3s. Come on Upgrade RC.... belted version of this tire! Your bigger 2.8 belted version is just a bit too big for the Mini XRT. But this size.... Worth it and love them, just suggesting how they could be off the charts good.
Absolutely garbage for the Mini XRT. First run, all the tires shredded. I mean left the earth! The rubber is not even remotely strong enough. What a waste of money. Do not buy these tires, they aren't worth the package they come in.
Perfect tires for my Mini Maxx. Great grip on the street, but doesn't traction roll unless I drive crazy, haha!
Reviewers are split on these pre-mounted 2.2" on-road tires. Several praise strong grip on concrete, hardpack and street surfaces, and good sizing for the Mini Maxx and Mini XRT. Others report tires shredding, tearing or coming off the rim during first runs, particularly on the Mini XRT, with some attributing failures to thin, soft rubber and lack of a belted construction. One reviewer found them useless on grass, which they are not designed for. Several reviewers asked for a belted version, and one noted the larger 2.8 belted option is too big for the Mini XRT. Sample size is small and reported experiences vary.
