Post Shore Ratings

I have a couple sets of tires that use Jaco's color shore rates instead of the numbers. I'd like to know what shore ratings pink & green are. Thanks for your help!

This is off jaco's website. Hope it helps. Ths only way to tell for sure what the shore rating is, is with a durometer.

2153 $16.00 Green (medium) standard
2154 $22.00 Pink (med-soft) low wear

2156 $22.00 Double Pink (med) low wear

Default tyre shore

Tyre Shore Front information
On road R/C racing tyres are rated by hardness or "shore". A softer front tyre normally gives more steering. However, softer front tyres wear faster than harder tyres (this is important to remember with a 4WD car for long races because front tyre diameter has an impact on performance and handeling). Generally, it is better to use harder front tyres (30 shore or harder) and find a chassis setup (shocks, anti-roll bars etc.) that makes the car easier to drive, rather than generate more grip using softer tyres.

Default rear tyre shore

Tyre Shore - Rear - Information

General
On-road R/C racing tyres are rated by hardness or "shore". The harder the tyre rubber, the higher the shore number. A softer rear tyre normally gives more traction, but tends to deform more which can cause instability. Also, softer rear tyres wear faster than harder tyres (this is important to remember with a 4WD car for long races because rear tyre diamenter has a direct impact on overdrive, which in turn has an impact on performance and handling). Generally, it is better to use harder rear tyres (30 shore or harder) and find a chassis set-up (shocks, anti-roll bars etc) that makes the car easy to drive, rather than generate more grip using softer tyres.
