Re: SV650SK6 tyres - trying PR4 instead of Z8s
 

How do you find out what the "standard" pressures are for tires? I think I've only seen the Max Cold numbers.

I've got a pr4 on the front which was vastly better than the massively worn out original tyre. Can't wait for the rear to wear out now to match it up.

That was with the Metzlers. The Michelins have always been 32/36. But yes, improved front suspension would be good. I have the emulators, but not really had a time when I felt like taking the bike off the road long enough to dismantle forks and send the rod to be modified.

By the way, looking at the spec it seems the rear is dual compound, but not the front. That could be why the front wears quicker. I also noticed the bike feeling a little "uneasy" towards the end, nothing serious but noticeable compared to the feel with a new tyre.

Anyway there's still some meat in the rear and it still feels fine so we'll see how long it lasts.

the PR4 fronts are dual compound. excess wear on the front just tells me that the front suspension is needing attention. i get between 7-9k from a front but i'm a fairly aggressive rider.

Cheers, I never really made the link between suspension quality and tyre life, but it makes sense. Anything I can do to improve tyre life is a bonus.

if suspension is too stiff then the tyre carcass flexes too much (something has to give).
if suspension is too soft the wheel 'patters'.
in both cases it accelerates wear. yes a tyres carcass should flex under normal conditions so it creates a wider footprint but should only be under certain conditions like cornering. setting tyre pressures properly allow the carcass to flex properly. too high a pressure and it wont flex enough creating wear. too low a pressure lets it flex too much again creating wear. your hot pressures should be around 10% of your cold for correct pressure (thank Luckypants for finding that out).
