The anakee to me is the very best wet weather tyre I have ever put on a bike..
The rp3 is the best all round tyre I have ever put on a bike
.....................
If you live in the uk ( it rains alot) then go anakee..If you tour alot in Dry weather then rp3...
Both tyres are the top of the range, and I doubt you will ever ride beyond the tyre in this coutry ( legal speeds)...
Do you ever go off road...never,,,ever...rp3
A tiny bit off road, maybe a bit of goat track (b or c roads ) then anakee..
BUT, you knew this already..as for longevity..thats your prob..will the anakee outlast the pr3 ? I would SUGGEST that the pr3 MIGHT last longer at high speed that the anakee just because the anakee is a duel purpose tyre..but the tread on the anakee is massive....9mm (I THINK)...
