so either PR4's really are crap compared to these other tires and i have no idea what i'm missing, or BAHAHAHAHHA what a load of bollocks
they are testing the high load version of the tires so, they're heavier than the regular versions (usually stiffer sidewalls), makes a difference, but apparently only on some of these tires. also, they set the PSI to the BMW recommended spec for the bike (which are the metzeler z8's btw), but not the specific to the varying manufacturer recommended spec...also makes a big difference.
i like how they used the heavy load tires because they're "what you're most likely to use on a touring bike" but then, one of the reasons the PR4's got 6th was because it was too much like a touring tire and not sporty enough profile. which is true, it's not a sporty profile but i find that a bit hypocritical. use touring tires (on some) but test for sportiness on a sport bike and give negative feedback for lack of sporty feel...makes sense...
an FYI the Z8 is the OE tire on that bike, and the r1200rs is classified as a "sport" bike and not a "touring" bike, while it falls more under sports touring its true but which do you want, a sports tire or touring tire?
and more to note, the metzeler roadtec z8 interact c is the heavy load tire. they list the pr4 gt (heavy load option) but only list the standard z8, also, the bridgestone t30 evo (single ply) isn't the GT spec either.
dunlop roadsmart 3's were correct as the current options available are standard or SP for lighter bikes (single ply rear)
conti roadattack 2 evo, also not listed as GT version, which is available.
and, the roadtec 01 is replacing the z8, good on them that conveniently their newest tire outperforms the old one.
wheres the pirelli angel gt here? thats generally considered on par for most sport touring tires and in MCN's own reviews equal to the Dunlop Roadsmart 3
sorry, i'm bored at work and very much dislike MCN's testing for most things
grip being the same, according to him, then what was the criteria for the test? where are the 0-60-0 etc times? which ones stopped better or gripped better under acceleration? throw on the anti crash bars and how much lean angle do you get in the wet with each one? bah. sorry to poo on your post dustin
editing in: another comparison of the same tires with again, not great info, just results
