Cool Rain, Roads, Hydroplaning

Hey Ya'll. I love my Metzlers when it's dry outside....But it's pretty scary when raining and windy on the Highway. I'm interested in Avon Storm II's or maybe the Michelin PR III's. The AS II's have been around awhile but the PS III's still not available to my knowledge. Anyone out there care to comment on the AS II's regarding hydroplaning, overall comfort, cornenering grip and endurance before they become useless relics!! -Dr Ron

doc52,
just curious what kind of Metz are you talking about? Are you sure they fit your bike?

I love Metz Z6 and prefer them over any other brand - esp in the wet...

Take care!

The Storm 2's have great wet traction, great dry traction, good life, and great handling that lasts right down to the wear bars.

Haven't run PR3's yet, but my PR2's also have great traction wet or dry. They get slightly more miles than the Storms, but the dual-compound means they wear into a "triangle" shape such that the handling goes noticeable off well before they hit the wear bars.

I've never run a front PR2 down to the wear bars because I always hate the way they feel and pull them off "early". I've run many sets of Storms right down to the end without complaint.

In fact, the PR2's on my current GT (put there by the previous owner) are ready to be replaced even though they have a few more miles left in them. The local Cycle Gear had PR2's in stock and would have mounted them that day, but instead I chose to order in the Storms and wait a few days for them to arrive.

It's worth it to me.

When the PR3's are readily available, then I'll try a set. But for now, I simply prefer the Storms.

So besides the numbering....what's the difference between the PR2 and PR3? Just the bigger better faster newer thing?

I found both listed here:

http://www.tiresunlimited.com/ALL%20...ilot_Road2.htm

http://www.tiresunlimited.com/ALL%20...lot_road_3.htm

and there's not a lot of difference that I can tell. Both dual compound. All I can find so far is:

"The Pilot Road 3 Front features a wider soft-compound than the Pilot Road 2...."

Even the Michelin site doesn't have the 3's listed yet? http://www.michelinmotorcycle.com/

However the price is considerably more on the 3's. Guess that's to be expected though. Might be time to stock up on the 2's if they go cheap.

I do agree they wear a bit flat, but all tires seem to do that. And for the extra mileage I can deal with a slight decrease in smooth transitioning for the last bit of life out of them anyway.

As for wet traction I think the PR2's handle as well as anything I've ever ridden but....realistically I don't ever push too hard on wet roads. Just kind of common sense if you're on two wheels and it's slick. Take it easy and slow down.

I guess it's a matter of degree. I don't get a slight flat spot, but two clear sharp edges where the compound changes that has a definite negative effect on handling. It gets so bad that I'd rather take the tire off and throw it away with probably a couple thousand miles left on it just because it sucks so bad.

BTW, the dual-compound Bridgestones and Roadsmarts also do this, but not to the same degree as the PR2's.

Never had that problem with the Storms, which are a single-compound tire, so they wear evenly the whole time. Also, I prefer the initial profile of the Storms, which give good handling and quick corner transitions but maintains straight-line stability.

With 20 front and 29 rear tires on my '07 GT I've tried them all, and I have a pretty good feel for what works for me and what doesn't . . .

Thumbs up Metzler Z6 , 2010 models, new last spring

I spend a lot of time on Rt 440 and 540 between Raleigh and the mother ship out in the country. It really hydroplanes in the wind and wet, like scary. My pressures are always 38-40 front and rear. Dealer thinks it may be due to the offset of rear tire compared to the front tire, unique to the K1300GT, and not a rubber compound problem so much as the lack of a central water groove and/or sipes to reinforce good grip in the wet, particularly with crosswinds or eddy currents from trucks in front or along side on the highway. It's the only tire I've put on that bike which acts this way. I used to put Bridgestone BT02's on it but they wear too quickly and lose feel too quickly for my taste. Think I'll order up a pair of AS II's. Thanks for all the input my moto-Brothers. Live long and prosper!

Would you please explain "offset of rear tire compared to the front tire" for me? Thanks.

Around here in Southern California, I won't buy a tire with a central water groove or anything similar where a near-linear cut runs down the center of the tire. Those tend to grab the rain grooves cut into the freeways, especially the deep ones. (I haven't seen fresh deep grooves in a while.) The freeway groves tend to grab the tire and make tracking less stable.

High Mileage Tires

Surprised that Meese ran through so many sets of tires in 138,000 miles. I typically like Avon and get close to 10,000 miles/set. Tried Metzlers once and got scared everytime I would lean over in the rain, took them off early. Dealer suggested PR2 and my current set has 11,000 miles and still look pretty good with even wear. Including the original set I am on the 10th set in 88,000 miles, and no, I don't ride them untill they are bald. Twice I have changed them before it was neccesary because I was leaving for a longer trip and didn't want to take time to change them on the road.

I'm sold on the PR2's. The current set I am using, according to my dealer are new part number made for heavier sport touring bikes. They are lasting longer and wearing better than the previous PR2s I have had so maybe it is more than a sales pitch.

Yeah, I'm kinda hard on tires, and on bikes, too.

I average 6-7K on rear tires, and 9-12K on fronts. Sometimes I get worse than that, sometimes I change early for a long trip, and a couple of times I've gotten a puncture.

Tires are simply a consumable expense, like gas & oil.

Agreed on mileage with the PR2's. I seem to average about 6500 on the rear. But I'm always riding loaded and highway speeds.

Well, it isn't unique to just the 13's. I have it on my 12 and on my old RT. There is a slight offset between the front and rear wheels. I notice it in the wear of the tire. More than could ever be explained by the crown of the road. I've seen others over the years make reference to it but I'm not sure I've ever seen a definitive answer as to why.

Might have something to do with Der' Fatherland engineers wanting the bikes to pull one way or the other because of torque / tracking? Maybe left over from the years of sidecars? Maybe the single sided arm thing. Or possibly because of weight distribution. Dunno.
