Has anyone used both, and able to offer a comparison ?

10,000 miles and time to replace.

I'm leaning towards Pierelli. From various posts, seem to match my riding better. Which is 95% secondary/5% Divided Highway. Lots of road snakes, and moderate level of frost cracks.

Looking for input from owners experienced with only one brand as well.

Did a search on this, and the other kawi site.

Not interested in dark side. Leaning towards 200/70 rear.

thanks

I am very pleased with my Pirelli MT66s. I was considering the 880s but read some tire reviews that discussed issues with them breaking loose on wet asphalt.

Wet, dry, straight, curved, grooved, the Pirellis eat the miles right up..

I haven't had any issues with my Metz 880's in the rain, but I don't push ANY tire on wet pavement/asphalt. With the rough roads here in Oklahoma (100's in the summers, single digits in the winters) there are a TON of folks who recommended them, so that's what I went with. Can't say I've had any experience with Pirelli's for the bike, but used to run them on my car and loved those too.

I've had the same experience with the MT66's on two different bikes now. Excellent grip and wear characteristics regardless of road surface. Can't beat the price either. The bang for the buck is incredible.

Just put a Me880 back on. I had a Pirelli RT66 rear on the front of my bike. I had to take it off because it got some really weird wear pattern on it I think caused by a nail and running it flat last fall, it deteriorated from there. But I believe the weird wobble I was getting was caused by this wear. However, I wasn't sure if it was that or the tire so I went back to an ME 880 which I've had before and it was a real solid tire. However, when it was new I believe the Pirelli was a pretty nice tire too. However, I had a wobble then too at about 105. That was caused by my steering nut being WAAAAAY too lose, I think, Like I said, I JUST got the Metzler back on. But I had a fairly good ride home today and I didn't have any problems.

Now I wish I had put the same Pirelli back on. Rear tires have a BUNCH more tread then fronts do. I had over 12,000 miles on the Pirelli I took off and it had 5 millimeters of tread on it still. It was only half worn! But it was funky shaped and I don't think it was the tires fault.

+1 on Pirelli. Silky smooth ride, good grip, favorably priced.

Thanks for the input, both direct experience, and suggested sites.

Ordered Pirelli 66's in oem sizes. Will report back with my results in about a month.

Please do. I've run Metzs but haven't tried Pirelli's.
Sounds like others have had good service with them.

I'm running Pirelli MT66, with 34 and 38 pressures. Just for grins I went to Pirelli site--the rate min/max pressures for 130/90-16 front at 32-42. They rate 180/70-15 rear at 36-42. Same for the 170/80-15.

I'm running a 170/80 rear instead of the stock 180/70, because it's $20 less money, and 3% larger in diameter, correcting some of the speedo error. Pirelli says the max load for the 180/70 is 827 pounds, and for the narrower 170/80 it's 908 pounds--81 pounds higher max load for the narrower tire. That's a surprise.

145 miles on the Pirellis, and they are just awesome.

Frost heave cracks, tar snakes, utility dig/repairs are just not the issue they were with the stock Dunlops. I would estimate effect is reduced by 75% or more.

Have not leaned them over yet, still weaving to break them in. But, the weaves are getting more dramatic !

Knowing what I know now if I was to buy another Vulcan 900 new or used, I would NOT take delivery of the bike unless it have Pirelli MT66 Routes front and rear. PERIOD.

I have about 4000 miles on them and they aren't even half worn. My Dunlops went out at 5800 rear, and 6000 front. The front wasn't worn out but it had sidewall cracks. I tried to get the rear to 6000 but it got to scary.

Driving in the wet...I catch myself going 55 in a good rain shower. The Dunlops I was good for 40-45mph with a tail wind.

Grooved pavement...Dunlops 30mph and it felt like I was riding on ice. MT66's Full speed ahead and that include steel bridges too!

Hi, New guy here.
I just brought home a 2001 1500 Vulcan Classic FI. The bike only has 8300 miles on it so the tires still look good, but I will probably change them because I worry about blow-outs with old tires. I live in the Pacific North Wet (Washington) and have had great luck with Metzler Marathons in the past, so I will probably go with them on this bike.

Going Back to Dunlops

I just replaced Dunlop D4046s with Metzeler 880s, big mistake. The Metz 880s behave really greasy, even on dry pavement - I've locked up the back tire on quick stops 3 times in 1 month. I don't remember ever locking up the Dunlops. The Metzelers may last longer, but at what cost to safety and security on the road.

Wow, I'm really surprised by this. Do you suppose Metzler has changed their tire compound? On my CB900C, riding two up with loaded pannier's, at freeway speeds in a driving rain, I've had plenty of traction with Metzler Marathons front and back. After your post I'm not quite sure which way I'll go. I did try the tires today at "higher than normal" speed without incident (no blow-outs), so I guess I can safely put off the new tires until the tread is worn down a bit more. Meanwhile, I'll be watching the tire posts on here.

RE:KV900C Run-In for new tires - Metzeler specifically states that "after fitting, the tire should NOT be used under maximum power or extensive cornering and not over 60mph (100KMH) for the first 200 miles to adjust the tire/rim assembly. After run in, speeds may be increased progressively". There is mold release on the new tires and the tread surface is very smooth from the mold itself, amongst other things. It takes a bit to wear the mold release off and scuff up the tires to get maximum traction, and the sidewall will flex more naturally, too. If you went balls out right after they were mounted it's no wonder they would be slippery and lacked traction, etc. You may think otherwise, but they tell you this for a reason and its not just a CYA. Lots of things need proper break-in to work their best. Bikes are a pretty big investment and repair and maintenance isn't cheap either. So it pays to follow the manufacturer's recommendations. It does sound pretty dorkey saying that. I've locked up the stock Dunlops more than I care to mention, and in rain, they are just scarey. My bike's in the shop and will be shod with ME880's tomorrow morning, 90/90-21 front and 200/70-15 rear. If you folllowed everything and they are that bad, go back to the shop you got them from; they may be able to do something for you. If you got them from a discounter online, good luck. Online can be cheaper, but sometimes for a reason. Remember, you get what you pay for or less.

400 Mile Report - Pirelli

Part of the reason for the replacement timing was to go on a charity ride with 300 bikes. Which went off last Saturday. Police escorted over 50 miles of secondary roads in suburban to rural areas outside Boston.

It was the "sister" ride to the one my crew organizes, so there were 18 of us riding together. 14 with a bsb. While we never put our feet down, it is challenging, in that you are formation riding, without some of the rider control you would have if riding independantly. Also, you have the police escort team swooping past often, trying to get ahead to block. So, a lot of minute adjustments, and dealing with hazards, without a lot of room to manuver.

The tires were awesome. Much better than the oem. Snakes, hazards, frost heaves, squirrly moves all good.

Next day, went on an extended ride with a different crew of 6, rural to interstate. Ending with almost wot run up I 95 from RI. Again, all conditions, very comfortable.

My comparison is only between the OEM, and the MT66. But, I would grade the the Pierelli an A-, vs the OEM's C-

i wanna say dunlop... but not sure. the roads around where i am are not known for being nice and smooth, but the old tire seemed a little softer, course i wore through it pretty quickly, sooo.... lol.
i like my pirelli's. i am very confident with their traction, i was just surprised that they were as "firm" as they seem to be.
