questions on v front michelin

[MACOP1104]

What do you guys suggest for getting a bit more tire life out of a rear Power One B?  I'm using a V front,  B 160 rear on my SV650 and my only complaint is it seems to wear out quickly.  I use 30f/22r cold.  It might just be that my pace is picking up and my fat ass is using the tire more (finally broke into the 19s at Roebling).  I'm 205 w/o gear.  Also,  I noticed the 160 is made in Spain and the 180s are made in France??? 
I just switched to a 5.5 rim onmy SBK so I'll be going to the 180 next weekend.

Thats pretty good on a lightweight bike. I didn't quite get to the 19's on my Ducati 800 which uses the 180 rear tire. I seem to think that the Michelin rear goes pretty good even when it looks like it is worn out. I have run the A rear tire down to the absolute limit and the traction remained good allowing me to turn lap times within a second of my best times at a articular track. I also do believe that the 160 tire being used on the SV is a different animal where I have heard of many SV riders complain about it. Sadly, I don't know the details.

That's what I thought when I saw it was made in Spain.   Well, I'll have the 180 on the SBK and I'll continue with the 160 on the Supersport..

Al seems to do real well on the 160 turning some good times on his SS. He kept up with me and passed me a couple times.

I switched to the 180 mid-weekend at the Jennings CCS round and liked it a whole lot better.  The 160 is just ok, but the 180 is a different animal for sure.  I just ran the 180 again this past weekend at Jennings for the WERA event.  The temp was 100 in the shade on Sunday and the rear stuck like glue all day with a cold temp of 20psi, 25 Hot off the track.  In practice at 22psi, the rear was sliding a bit.  The front was the one giving me a little trouble.  I've never had any trouble with the front "V" tire.  Not a single slip until this past weekend.  I had about a Half lap lead in the SOLO 20 Lap race when on lap 17 the front tucked on me between turns 5 & 6.  Luckily I was able to save it on my knee, but damn, that surprised me.  Then during one of the sprint races it tucked again on me in turn 8.  The bars completely turned to the stop but somehow I lucked out again and pushed it back up.  I was running it 30psi cold, 35psi hot.  Weird, I've always loved the "V" front.  But then again, we are talking about Jennings and 100 temps.   I love the track, but man, it really needs some new pavement.

Thanks for the feedback.  Weird about the V front.  The temps and the track I'm sure, or maybe just a bad tire...

What temperature was the front tire at coming off the track and how much time did it have on it?

[PlayHard]

The tire was Brand New for the Solo 20, zero time on it.  Scrubbed it in as good as I could during the sighting lap.  Incident occurred on the 17th. lap.  Funny thing is, I had throttled back because of the lead I had so I wasn't even pushing it hard.  The 2nd time the tire had about 40 laps on it.  Not sure about the temperature. I don't have an instrument for checking that, just tire pressures.  The track itself was Super Hot, the ambient temperature in the shade was 100.  I'm sure the tracks surface temperature was roasting hot.  Jennings is not known for good grip when its hot so I'm not putting that much blame on the tire itself.

I wasn't sure what adjustments to make with tire pressure on the front.  I know that the back works better when its hot if you lower the pressure, which I did, and had no problems with the rear at all.

The guy next to me was running Dunlops and had one rear come apart on him.  Luckily he didn't crash.

Were those Dunlops a Daytona tire:) I would like to hear more on what to do in just that situation of a hot track. I expect PBIR this memorial weekend to be the same. I may have to invest in one of those portable A/C units.

I just mounted the 180 tire and according to my math the diameter is 8mm more than the 160.  I plan on dropping the ride height by 4mm.  When you switched from a 160 to a 180 did you make a similar change?

You put a 180 on the back and didnt change the chassis? No wonder you were having front tire problems, you just dropped the front end 5mm.

[MACOP1104]

Just used the 180 (power one B) at Roebling for the 1st time and loved it.  I dropped the ride height by 4mm and it still felt a bit tall in the back.  rip was awesome and tire wear was way better than the 160
