    Hi

    I bought my 2010 Griso 8V last year and love it. It came with Dunlop Qualifiers on it but they didn't last too long, so I replaced them with Mezler Z8 Interacts, but I am not getting on with them.

    I am running 36 - 42 psi but the front end feel is horrible, further to this the tyres seem to loose 2-4 psi every 10 days.

    I'd love to hear what tyres and pressures you guys are running and your opinions.

    Grazie
    Simone..

    I've heard good reviews on the Michelin Pilot Road 4's- might be worth a try. Also, Micheline Pilot Power 3's and Dunlop Road Smarts seem to be well regarded by other Griso owners. All seem to be giving good wear and performance. The Pilot Road 4's are fairly new to the market so it may be a little early to tell with regard to tread life. I believe the pressures you're running are reasonable, but I'm a Griso newbie myself.

    I put Metzler Z8's on the front and rear of my Griso 1100 but not being one to push tires hard I'm happy with them. They only have 3,000 miles on them so it's to early for me to really tell how long they will last.

    My Griso was Todd's old bike the tire pressures were 33 front, 36 rear. I've kept the pressure the same even though I weigh 225 lbs (and still dieting) . I use a Lezyne Mountain Bike floor pump to maintain pressure as it has the most accurate gauge out of all my many gauges and pumps. I don't think I'm loosing a pound a month.

    I used to help coach a High School Mountain Bike team so tire pressures are real important to me. You'd be surprised at how much of a difference a pound our two makes in a X-Country race and unfortunately every rider / course combination is different.

    I currently have the Michelin Pilot Road 3's. I have about 7k miles on them, they probably are about done. I run them at 34 psi front and 36 psi rear.
    The feel you may be able to improve by adjusting the pressure. The losing pressure part is another matter. There are cases of the spoked wheels losing air, but the cast wheels really shouldn't be. Are you sure you do not have a nail, screw, or other issue with the tire? Also check the valve, soapy water helps to find a leak.
    I have a fairly nice gauge, and I have in the past compared it to a known good reference. The race track is a good place for that, the tire vendors usually have a very accurate gauge.

    I have about 4000 mi. on a set of Pirelli angel gt's. I run 34F/40R. Very little visible wear and the grip/handling is great imo.
    A little pricy but well worth it.

    After 60k miles on 2 Grisos I found Michelin Pilot Roads to be the best balance between grip (in wet & dry weather) and miles per buck. The only trouble I had was that the fronts tended to lose their profile and upset the handling before they wore out and rears could go from being fine to completely knackered in a very short time - it was like they wore predictably for thousands of miles but once they reached a certain point they would turn from fine to dangerous almost instantly.

    I use Bridgestone BT023GT, lots of grip and hard wearing. Rides well. But be sure to get the BT023GT, not the BT023.

    I have Pirelli Angel GTs on my 1100. So far pretty happy with them.

    Hi,

    the original Metzeler tires slided too much and were out in 7000 km (4300 mls).
    I bought the Michel Power Road 3. I think (almost) the best.
    Good grip and safe feeling in wet and dry, they lasted 13.000 km (8100 mls)!!
    Now I'm riding Michelin Pilot Power 3. Huge grip, fast warming up.
    I don't know how long they will last.
    I hope somewhere in the middle of the Metzeler and Michelin PR3...

    I've got the Pilot Road 4's on mine. My initial reaction is positive but I don't have too many miles on them. I'll know more after I flog the daylights out of them on the first sunny day of Spring here in the northeastern United States :)

    I'm on my second set of Angel GT's on the K1300 and they are by far the best tyre I have ever had the privilege of wearing out.

    Michelin Pilot Road 3's; going to the 4's next change. Excellent wear and grip IMHO.

    Guys. Thank you all so much for your POV's my Z8's still have enough rubber to get me through spring so I'll persevere a while longer and experiment with some of the pressures you use.
    Grazie mille.

    sun is coming.......

    I can't comment specifically in relation to the Griso but everyone I know who has them raves positively about the Michelin Pilot Road 4's. A mate runs them on his torque monster (GSX1400) and says that in relation to the previous PR3's they are grippier, inspire more confidence, and are wearing more slowly than the PR3's. I'll be putting a set on my GSX1400 when the tiem comes.

    The compounds may have changed since the earlier posts on here, but the Z8's on my 2015 Griso stick like baby shit to a blanket! It's my first experience with Metzelers, having been strictly a Michelin man on my Tuono for seven years, but I'm happy with them so far. Mileage will be the main determinant for me. My two cents!

    While it's fun to read people's opinions on tires, they are just that. On the track, the only thing that mattered to me was lap times. On the street, I trade off wear for traction here in SoCal, land of the endless twisty heaven. Some are completely opposite and care only about mileage (as evidenced by Gold Wing riders using car tires)... So as always, YMWV. On the street, I use Dunlop RoadSmart II's exclusively, everywhere I can. Bummer they aren't offered for the V7 or Cal 1400. Pirelli's seem to be flat magnets, on all of my bikes that have had them (and the handful of others I service here), and on my '12 F150 FX4 I just sent down the road.

    Tire and oil threads go on forever, yet never go anywhere.

    Interested to know what you have done with tyres. I read through and see some interesting debates and suggestions. One of the most important is to run them in and it sounds as though you have a issue as loosing air means that they might not be seating correctly. I hope you get them sorted.
    regards Vinny

    Hey Vinny
    No resolution yet. I've only put 3000 miles on them as the weather in London is still a bit rubbish, will try refitting them if only to bring peace of mind and help with the trouble shooting.
    Have to say though that when they work they are a good tire a give good confidence.
