I can't really tell them apart from the tread patterns.
Ralph has a slightly thicker and more cut resistant carcass. The Ron has the same carcass as the Furious Fred, so thin. Usually the Ralph is good when it's dry and the Ron better on muddy or loamy soil. Careful on rocks though. The snakeskin version of the Ralph is much more durable for little weight penalty. Ron isn't available in snakeskin. The Ralph is also available in Double Defense which is like riding solid tyres. Yuk.
Ron Snakeskins will be available for 2012 allegedly.
I'd echo Gee's thoughts though generally. I really like the Ron as an all rounder. If you want fast combine with a Fred on the back. If I'm going anywhere with rocks I'd use Ralphs instead.
I had noticed the Furious fred is markedly lighter - too light for me for a dry to intermediate tyre in standard guise - but the UST Fred looks to be a more sensible weight, and one would assume, better durability again.
Edit: I mean Rocket Ron in UST
Crikey! 😯 You building a race bike Burgess?!?
Have a look at the Hutchinson and Vredestein tyres on CRC too...

No, not faintly. You've just been spending too much time with your fast friends! 😉
Ear is ok btw - some 'nice' bruises on arm and side though!
Ralph faster but sidewalls are like paper
If you're talking UST then Ralph, but I'd not get the USTs - they're chuffing heavy and expensive. IMO the USP of Schwalbe is that they work, while being light.
