Ah, the anticipation o.f a "new and improved" model beyond the PR4. We will have endless tyre treads.
Talk of grip, tread life, cost, fitment the list goes on.
The motorcycle tire selection has never been better.
I had Goodyear "Grass hoppers" on my 64 Sportster and though they were great.
What vintage tyre did you have on your first bike??

Talking to the rep at the SLC BMWMOA rally, he said only that the PR5 would be out by early 2018, but was not willing to provide any details.

EICMA is coming up November 9-12, a popular event to introduce new products.

I distinctly remember the upgrade in braking from the early Dunlop Sport Elite tires. On my 83' CB1100F I used to play with the front brakes to chirp the factory semi-rib design front tire on demand. With the Sport Elites the bike just nose dived from the new found serious stopping power. Several years prior to this Honda I rode a Norton 750 Atlas briefly and the front tire didn't matter on braking as dragging your feet on the ground was almost as effective as the single leading shoe front brake on it.

It's a good time for riders with all the quality rubber out there. I've been a long time fan of the Michelin PR series EXCEPT the 4. Right now I'm having good results with the Dunlop Roadsmart 3, but will keep an eye out for the PR5 reviews.

Goodyear "something's" on my '71 Sportster. Since my brother had a set of old tires on the '58 Duo-Glide he bought, just sitting in the attic, that's what I put on the Sporty after the rear blew.
Tread?
Grip?
Nah, it was round, black and was free. We didn't have money so we just re-used tires over and over.

Just saw a Michelin ad in the November BMWMOA ON. Lists previous models of the Pilot Roads, asks "Guess what's coming in January?"

My first mini bike had small go-cart sized tires. These tires lasted indefinitely riding in the farm fields. Never had to replace them.

Just bought a set of Dunlop RoadSmart IIIs which had a $100 rebate. The Dunlops will replace Michelin PR4s which only lasted 8,500 miles (rear). The tire manufactures all seem to promise longer and longer wear but I have not experienced any real improvement over the past 10 years.

Great links to the new PR5! Looks like they have listened to customers. With less siping in the front tire it might take some of the squiggly feel under hard braking away. Having solid rubber on the outer edges should help the numb feeling when leaned way over. I might be ready for a set of tars by the time these are available.

Very interesting tread. The videos all show a sport bike in wet conditions.
The latest U tube rates tires by lap times in the wet with the PR5, Metzler 01, them Pirelli GT, Conti Road Attack 3,
Bridgestone T30 EVO, Dunlop Road 3. Same bike and rider?? Video doesn't say.
All the tyres did well. Any of the six would be good choices.
Cost will be a factor too. We have all Vinter to speculate and discuss.
Now all we need is a new oil to hit the market.

Cost will be a factor. It seems that every time a new tire is introduced the manufacturer claims anywhere from 10 to 20% extra mileage. I pay attention to user posts about this....and so far there really isn't any improvement in tire mileage across the major brands in the last couple generations. Some have gone backwards. I was buying T-30 Evo's for $225 shipped. That went way up. PR4's are around $330 at best. If these come in higher than that, not sure if I want to pay to test them out......
