Hey Rudy,

Not long ago (around the release of the 2-Stage tires) Jaco revised the material of both the front and rear wheels along with a slight design change for the fronts. The new material is much more durable, I haven't lost a wheel to it yet. The changes to the front wheel were to the inside bearing boss which was notorious for cracking very easily. The new one is huge in comparison to the old one, more material where it counts. The new wheels look identical to the old ones with just these minor changes. The new wheels are shipping on all the compounds, not just the 2-Stage stuff.

For everyone here, if you haven't run Jaco rubber in a while due to them being fragile I would have to suggest giving it another shot. For years and years Jaco has made the best tires in the business and this simple wheel strength issue prompted a lot of people to switch. Now that it's fixed I couldn't be happier, it's like having the "old Jaco" back again.

Please note that I am in no way affiliated with Jaco, just your Average Joe who hates losing a tire after one accident

On another note, have you tried the 2-Stage tires yet? We have been having great luck with them locally and they are amazingly durable. After a few months of racing no broken wheels and not a single chunked tire and the low wear makes them well worth a few extra bucks.
