Tire Wear Potentially Affecting Bike Handling

2010-2013 RSV4 Factory and RSV4-R - www.apriliaforum.com
Issue

So I have almost 1300 miles on my ?17 RSV4RR ? as such, I?m still on the OEM Pirelli Diablo Supercorsas ? and I?m suspecting tire wear may be affecting the bike?s handling (rear skidding/sliding feeling when leaning the bike over).

Background

Unfortunately, the vast majority of those miles (~1000 out of the 1300 miles) have been either highway or non-twisty roads to get to the twisty roads. To compound the problem, I admit I haven?t always been good about running the ?best? tire pressures for straight roads to minimize tire wear / flat spots.

Note #1: My preferred tire pressures are 33F/31R for canyon riding, and I would aim to (but not always do) run 33F/36R for straight line / highway riding.

Now when I lean the bike over, it feels like the rear is skidding/sliding until it gets into a certain lean angle (i.e. part of the tire). I don?t know if it means anything but it almost feels like the feeling is more pronounced when the tires are warm.

Note #2: When the bike is leaned over beyond a certain xx degrees, the rear feels planted and stable. It?s only when not leaned over that much or transitioning that the rear feels ?loose? ? definitely a unsettling feeling.

My Theory

I?m suspecting what?s happening is that the Supercorsa profile may not be perfectly round anymore and when transitioning from straight up and down to on its side, the rear tire is either transitioning very/too fast or it?s slightly skidding/sliding.

Note #3: I don?t have prior experience with Supercorsas and never experienced this skidding/sliding experience before.

Questions

- Does my theory about the tire losing its profile seem like a plausible root cause? Is there something else I should be considering?

- Is there a way to improve the condition (i.e. minimize the skidding/sliding)? Change tire pressures (even though I?ve already experimented with this)?

- Is it necessary/best to buy new tires (probably something less aggressive/sporty) at this point?

Any feedback would be appreciated.
