The AKA Racing Grid Iron Tire in Hard compound has a low-profile tread with small, staggered square spikes arranged symmetrically across and around the tire to provide a superior balance of forward and side bite. Long, staggered center lugs add a little extra forward bite, and greatly increase tread life by reducing wear.
The AKA tires have already set new standards in competitive RC racing, but the real buzz is about the superior performance and MUCH longer life of the inserts that are included in AKA tire/insert sets. The inserts included with most other brands of tires are far too soft and degrade well before the tire is worn out - sometimes as quickly as a single run. That means much of the performance of their tires is lost because the inferior inserts fail much too quickly. The AKA factory drivers have run a single set of inserts through at least 10 to 20 sets of tires! They are simply that durable. The inserts are also precision ground, which means the insert fits the tire perfectly right off the shelf - no trimming required. The inserts are also very well balanced, and don't degrade when exposed to water, so you can count on having the best performance from your tires as long and they'll last - and for the next 20 sets of tires!
