Overview
This is a pair of Reaction HP SC 2.2"/3.0" Ultra Blue Belted Drag Racing Tires. The Reaction HP is now available in the new super soft, ULTRA BLUE compound to provide even more incredible grip from the legendary Pro-Line Reaction tread design. Tested by some of the nation's top No Prep racers, this new compound provides relentless traction off the line and stability at the top end with little to no break-in or conditioning needed: so, you can go faster, faster.
As always, the Reaction HP Ultra Blue features Pro-Line's High-Performance herringbone weave pattern Belt, for little-to-no tire ballooning or expansion and is proudly Made in the USA. Get maximum grip and stability so you can be faster than your racing buddies with Pro-Line's all-new Reaction HP Drag Slick SC tires!
Please note that the Reaction HP tires have a maximum speed rating that, if exceeded, could result in permanently damaging the internal belt. For the Reaction HP SC tires that is 90 mph or about 7,000 RPM. Over revving your Reaction HP tires could result in breaking the internal belt, which will NOT be covered under warranty. This can be caused by "diffing out" your tires or holding the throttle open while one, two, or three of your tires are stopped, which substantially increases the RPM sent to the free-spinning tire or tires.
Please note: All tires & wheels are sold in pairs, unless otherwise noted

Overview
The Pro-Line 1/10 Reaction HP Ultra Blue Rear 2.2"/3.0" Drag Tires represent the pinnacle of drag racing performance for serious RC racers in the UK and beyond. This pair of high-performance drag slicks has been purpose-built for short course trucks competing in no-prep drag racing, where raw traction and stability matter most. Whether you're a weekend racer looking to improve your ET times or a competitive driver aiming for podium finishes at RC drag racing events, these tyres deliver the grip and reliability needed to dominate the starting line and maintain control through the finish.
What sets these Reaction HP Ultra Blue drag tyres apart from standard RC car tyres is the revolutionary new ultra soft compound that Pro-Line has engineered specifically for drag racing applications. Tested extensively by some of the nation's top no-prep racers, this breakthrough tyre compound provides relentless traction off the line, exactly where it matters most in drag racing, whilst maintaining excellent stability at the top end of the race track. Best of all, the Reaction HP Ultra Blue tyres require minimal break-in or conditioning, meaning you can get out on the track and start posting faster times right away without weeks of preparation.
For UK RC enthusiasts seeking the best drag racing tyres available, the Pro-Line Reaction HP Ultra Blue represents genuine performance innovation. These are not all-purpose RC car tyres; they are specialist equipment engineered for a single discipline: winning at drag racing. Available through RC Model Shop, these authentic Pro-Line drag tyres give you access to the same technology used by professional racers across the country.
Key Features
- Ultra Blue Super Soft Compound — The brand new ultra soft compound in these Reaction HP tyres has been formulated to deliver exceptional traction from the moment you hit the throttle, providing immediate grip off the line without requiring extended break-in periods or chemical conditioning treatments that consume valuable track time.
- Herringbone Weave Pattern Belt — Pro-Line's signature high-performance herringbone weave pattern belt is moulded directly into the tyre structure, which effectively prevents tyre ballooning and expansion during acceleration, keeping the contact patch stable and consistent for predictable handling throughout the race run.
- Minimal Break-in Required — Unlike many drag racing slicks that demand extensive conditioning and multiple heat cycles, the Reaction HP Ultra Blue tyres are ready to deliver maximum performance with little to no break-in period, allowing you to focus on driving rather than tyre preparation.
- Professional Race Testing — These drag tyres have been rigorously tested by some of the nation's top no-prep racers under real competition conditions, meaning you're buying a tyre proven to perform at the highest levels of RC drag racing.
- Relentless Off-Line Traction — The combination of the ultra blue compound and the herringbone belt design delivers the traction needed to achieve consistently fast reaction times and maintain straight-line stability throughout the entire race run.
- Top-End Stability — Beyond just launching hard, these tyres maintain excellent stability and control as you reach the top end of your vehicle's speed range, preventing the loose, unpredictable handling that can cost you races.
- Made in the USA — These authentic Pro-Line drag tyres are proudly manufactured in the United States to exacting quality standards, ensuring you receive genuine equipment that will perform as advertised.
- 2.2"/3.0" Short Course Fitment — Specifically designed for 2.2"/3.0" short course rear wheels, these drag slicks offer the correct sidewall height and bead seat geometry for optimal performance in SC truck racing.
Technical Performance
The Reaction HP Ultra Blue Rear 2.2"/3.0" drag tyres are engineered with precision to deliver the exact performance characteristics needed for competitive no-prep drag racing. The tyre construction features Pro-Line's proprietary herringbone weave pattern belt system, which is moulded directly into the rubber compound to provide structural support and prevent the ballooning and expansion that occurs under hard acceleration. This belt design is critical because it keeps the tyre's contact patch consistent and predictable, allowing you to launch with confidence knowing the tyre will behave the same way every single run. The ultra blue compound is significantly softer than Pro-Line's previous drag racing formulations, which means the rubber molecules deform and conform to the surface texture of the track more effectively, creating maximum contact area and maximum friction — the fundamental physics behind better traction. The sidewall construction is optimised specifically for the forces experienced in drag racing, where extreme longitudinal acceleration loads are applied to the tyre for short bursts rather than the sustained cornering forces experienced in road racing applications. These tyres are supplied as a pair, ready to fit to your 1/10 scale short course truck's rear wheels in either 2.2" or 3.0" diameter sizes. It is important to note that these drag racing slicks have a maximum speed rating that, if exceeded, could result in permanent damage to the internal belt structure. For the Reaction HP SC tyre design, this maximum speed rating is 90 mph or approximately 7,000 RPM. Exceeding this limit through over-revving, such as when diffing out one or more tyres or holding the throttle open while stationary, can break the internal belt and will not be covered under warranty, so it's essential to respect these limitations during use and maintenance.

Frequently Asked Questions
- What is the difference between Pro-Line Reaction HP drag tyres and road racing slicks? — Drag racing tyres like the Reaction HP are engineered specifically for straight-line acceleration and launch traction, featuring softer compounds and reinforced belts that prevent expansion under hard acceleration. Road racing slicks prioritise cornering grip and sustained performance through turns. The Reaction HP's herringbone belt design specifically addresses the ballooning problem unique to drag racing, where extreme longitudinal forces concentrate at the tyre's contact patch without the lateral forces of cornering.
- Do these Reaction HP Ultra Blue tyres need conditioning before racing? — One of the key advantages of the new ultra blue compound is that it requires little to no break-in or conditioning compared to previous generation drag racing slicks. You can use these tyres right out of the box with minimal performance loss, though some racers may still choose to run a few heat cycles to optimise grip further. This minimal conditioning requirement saves you valuable track time and gets you racing faster.
- What is the maximum speed rating for these drag tyres? — The Reaction HP SC tyres have a maximum speed rating of 90 mph or approximately 7,000 RPM. Exceeding this speed limit can cause permanent damage to the internal belt structure, which is not covered by warranty. This typically occurs through diffing out tyres (spinning one tyre while others are stopped) or holding the throttle open whilst stationary, so avoid these practices to protect your investment.
- Are these tyres suitable for all short course trucks? — These Reaction HP Ultra Blue drag tyres are specifically designed for 2.2"/3.0" short course rear wheels and are optimised for no-prep drag racing competition. They are suitable for any 1/10 scale short course truck that uses these wheel sizes, whether it's a Traxxas Slash, Team Associated SC10, or similar platform. However, if your truck uses different wheel sizes, you'll need different tyres.
- Why do these drag tyres cost more than all-purpose RC car tyres? — Drag racing is a specialised discipline that demands specialist equipment. The Reaction HP Ultra Blue tyres employ proprietary compound formulations, precision belt engineering, and have been extensively tested by professional racers — all of which justify the premium price. You're paying for proven performance from a manufacturer that invests heavily in racing-specific R&D and real-world competition testing.
- Do I need new wheels to use these tyres? — No, these Reaction HP drag tyres are designed to fit directly onto 2.2"/3.0" short course rear wheels that are likely already on your truck. The tyre bead is engineered to seat properly on standard SC truck wheel designs.
