My SR is a 2014, so I didn't start out with Rosso's.  I chose the Angel GT's because they should last longer and give me better traction than the original tires.  I like them better than my original tires, but I don't recall the stock tire on 2014's right now.

Stock tires for 2014 S and SR are IRC Road Winner.

I think they use such narrow tires for weight savings.  Now that I know you are using the Angel GT's successfully, I will definitely be putting them on.

On my 2012, I replaced the rear tire at 6000 and 13000 miles; the front tire was also replaced at 13000 miles, though it had a bit of wear left.

I replaced the rear at 10000, and again at 22000.   The front made it to 22000 before replacement.   Stock IRC tires.   Amazing YMMV,  I guess it all must be riding styles/conditions?

Your bike didn't come with the Diablo Rosso II's, which are sticky but short lived.  I just hit 6,000 miles and both tires have about 1000 miles left on them, with a noticeable flat spot in the rear.

Riding style definitely will affect; heavy acceleration and regen will affect wear. Rider weight will affect some too; I'm probably 210 in full gear.

I did replace the rear the second time when it picked up a nail, but it would have been due for replacement within a thousand miles anyhow.

I had PR3's put on my 2014 SR when I picked it up and the rear was a 150. I thought it handled well until I decided to go back to stock size with the Diablo Dorso II's. I was surprised how much more flickable the bike was in S turns. Would not go back to a 150.

Just as a counter opinion, I sought out a "flatter" tire profile because I felt my 2014 S was twitchy and unstable in turns (likely due to the steep frame geometry/lack of trail), and thought the Pilot road 4/3 (PR4 front/PR3 150mm rear) improved handling significantly--the bike can now hold a line and is more stable and predictable. It's all relative to what you prefer (which is often related to the bikes you've ridden before)--your "flickability" is my instability. I took the bike to the track with the PR3/PR4 combination and although it wasn't ideal (in that the PR3 rear appears to have less shoulder contact patch than a pointy tire like a Diablo Rosso), it performed fine for me with no sliding. The PR3 or PR4 are unbeatable in wet weather and are long-lasting, albeit pricey.

Note that the 150 rear also raises the seat height, spedometer appears to be more accurate based on radar signs, but the bike feels slightly slower off the line (could be my imagination...)

Anyone that has not already done so should get there suspension sag and dials turned by a pro.

I'm ~160 lb, and I had to cut a lot of spacer to get the sag within spec.

I just hit 6,000 miles and both tires have about 1000 miles left on them, with a noticeable flat spot in the rear.

At 6,300 miles, I've got threads showing on the rear.  I can afford a new set of tires but damn, the timing isn't very convenient.

[Ndm]

I can't stress enough the severity of a blow out at speed, there is a little triangle on the side of the tires, follow that across the center of the tires, it's the wear bar, if it is level with the tread replace the tires, period, if you see thread your life and others are at risk, don't be a cheap dick head

Yes, getting 4-6k out of a sport tire like the Diablo Rosso II is pretty typical on ICE bikes. My PR4 front tire (which I think typically goes 10k+ miles on the front) is getting some ridging after about 6k miles on the Zero and I'm wondering if the front wear is simply a dependence on the front braking the bike instead of the normal engine braking that occurs on ICE bikes.

I typed that post immediately after discovering the wear, so it is just a slight patch and not like I've been riding on it like that for weeks like that dude I saw on a stretched GSXR750.  I agree, the tire is dangerous and will be replaced very soon.  My only gripe is the timing and the fact that the front wears as fast as the rear.

Just saw this article regarding electric/hybrid cars and thought I'd post it here for discussion:

One of the complaints listed for electric/hybrid car owners is increased tire wear.

One of the complaints listed for electric/hybrid car owners is increased tire wear.

They attributed it to weight, not the awesome 106 ft. lbs. and regenerative braking.  The whole study sounded dubious to me.  They claim that only 1/3 of emissions come from the engine on an ICE car. 

We found that non-exhaust emissions, from brakes, tyres and the road, are far larger than exhaust emissions in all modern cars.

So if non-exhaust emissions is the real culprit, then the whole emission regulations thing is a scam?  Or an attempt wasted in vain?

[JaimeC]

I also question the methodology. If you're talking about weight, then what about all of those stupid overweight SUVs on the road that not only weigh two tons or more, but also get LOUSY gas mileage.

And particulate emissions from the brakes?  Magnetic regenerative braking doesn't create any particulate emissions.  I'm wondering if the oil industry didn't fund this "research..."

This is some bullshit. Lumping tire wear particles in with gases is a literal false equivalence. Smog and warming effects have a very direct relationship with atmospheric pollutants, not dirty road surfaces.

The sensible response to understanding the effect of tire and brake wear is to go fix those issues, too, not say that EVs are a wash. I'm guessing that conclusion drove the study and the write up.

Material advancements aside, these issues are addressed by improving vehicles and particularly electric vehicles using regenerative braking and aerodynamics that reduce power needs at speed.
