Have pr4 by on my BMW RT. The rear OK but front cupping and uneven wear. Will not use again. The angel gt was much better with good grip and long mileage, at least for that bike. I figure my standard suspension mts would do worse on front due to fork dive.
Just had a pair of Metzler Roadtec 01's fitted. Ditched the Pirellis after 1800 miles, just didn't like them in the wet.
Ok, fine. If it helps you out I'll pay the postage on the pirelli's [emoji6] Sent from my iPhone using Tapatalk
With the right tyres a good bike can feel like a great one. With average tyres it will always feel average
Seems to be some mixed messages on the Angel GTs here. I must admit I tried some Angel STs on my Triumph Street Triple a while back, but ditched those as they seemed very "wooden" no real feel at all, never had a slide, just didn't give me any confidence. Swap the for Metz 7rrs loved them. I hoped that the GT would be streets ahead of the old ST, I was going to put a set on for my 3000 mile European tour I'm going on this September wasn't sure how the Metz 01s front would hold up on my Std Multi given the amount of front dive and their particular tread pattern. I have tuned the suspension as much as I can given the limitations of the OEM forks and shock! Back to being undersided about what to go for now! BTW Pirelli said defiantly D spec rear for me for touring with luggage.
My experience with them (on my second bike - BMW F800ST) has been very positive, I do 120 miles a day on them and they are wearing very well, nothing abnormal at all. The grip in both wet and dry has been totally confident. Coming on for about 4000 miles so far on them. The Angel GT on my MTS - not exactly that happy with, despite their dual compound the rear is pretty much done after 3000 miles as even the slightest bit of squaring off, which is to be expected as I spend at least two thirds of my journey each day on the motorway, has put them below the legal limit. The wear indicators are miles away from the centre of the tyre and showing that I have "thousands" of miles left but it simply is not true. I would expect to get far more miles out of a rear than that doing largely commuting! I would be buying a new tyre every month LOL. The original factory tyres did over 7000 miles but was a far more sedate commute (30 miles, no motorway) than I do now.
Must be a difference due to bikes. On RT my rear Angel gt was replaced with 9 or 10 thousand miles. Would have done a couple thousand more if not for the nail. Started squaring after 7000 miles but I figured it was good to get that type of mileage, square or not.
I've been impressed with the OE Pirelli Scorpion 2's, but with a trip to the Alps and Black Forest planned for September I'm looking for something more sport than touring (and definitely don't need any off-road capablity). I like the look of the new Diablo Rosso III's. Might give them a go.
I've had the Z01's on since the start of the year some 4500 miles ago now and they are still looking like there is plenty of life left. At this stage the wear has created a nice solid feel for turn in, they seemed really quick to me originally. They don't appear to be cupping much and it's not to hard to reach the edge. I didn't pay for the first set but am seriously considering if I should pay for the next pair in a couple of months time. I have a spare GT front and it would make sense to just get a rear. Regarding the PR4's cupping, I've had this happen on both bikes I've ran them on as they approach the end of life.
I've just come back from a trip to southern France over and around the alps, I fitted PR4 GT's which I found to work really well, I was on a bit of a catchup so did 550 miles on the motorways which I thought might chew through them but there was no signs of motorway work. we then toured up and down the alps and the cross country home. So far I've covered 2,200 mile on them they still have 4mm on the rear and 3mm on the front. I haven't managed to get to the edge of the tyres which is a first for me. The only issue I had was the bike started to weave above 120mph + (with panniers on and full) I don't know if it's front or rear tyre which causes this issue but other than that I'm really pleased with them.

If you're touring then keep in mind that the Diablo Rosso's aren't a touring tyre and I wouldn't expect them to last very long if the OE Pirelli's are anything to go by. I liked the OE Pirelli's but the Bridgstone T30 Evo's are in a different league and they're the right tyre for the job - I rode them to Germany and back and found them to be wanting for nothing, no matter what the conditions were.

I love the way you guys are getting so many miles. I wish I could ! I was on the trip to the alps that andyh caught up. New pr4gts fitted before leaving. 7 days and 2k miles in and the rear had no tread in the middle, and not much left on the sides. I was riding 2 up, and with luggage for all but 2 of the days. I have an enquiry in to Michelin as I wonder if the tyres ran too hot in the 30+degrees we had down south. The other guy on the trip wore out a diablo corser on his triumph 675 in 1500 miles, but that's a sports tyre. Anyone want to take me on as a tyre tester
My Z01 are 2000 km now, all of them in Spanish mountain roads, always with my wife. Outstanding! Terrific! I have tyres for a long long time, despite each set will not last more than 4-5000 km.
If your running in European wet whether the Mich PR4 was the right choice, anyone mentioning to me about southern Portuguese/Spanish heat and gravel gets Pirelli Angel GT, T30's for a more spirited ride the more sipes in the tyre means more heat build up to get better traction in wet weather, northern equator riding see's temps easily copable, but increase the heat, the tyre softens, oils leach causing a blue tinge, loss of mileage, then try riding that blue tyre back in wet Britain, it feels awful hot touring= find a tyre with less but larger sipes of course we are yet to see what the Z01's deliver in the heat but a tyre so much like the Mich PR4 to me says it'll do the same in hotter, dry touring just my 2 pennies of what I see from returning customers
Andy, question for you. I know there is a lot of talk about tyre pressures, and some run real low (imo), but I used the recommended pressure of 42 psi for the rear (used 38 in the front rather than recommended 42). As I said we were two up with full compliment of luggage. What in your opinion should I aim for in terms of hot pressures ? I know what you mean regarding overheating. The last two days when the tyre tread was low the tyre felt horrible. I didn't trust the grip level fully. My rear was balling up, and the edges of the side treads of the tyres developed what I can only describe as flaps or ears on their trailing edges. I often get this (have done for years, regardless of which bike, when pushing on and trding 2 up)
42 rear is about max, I've one customer similar to your useage and he adds another 2psi because he say it feels squirrely when hot, the symptom I would say is more tyre design than pressure in it, but he like um so he gets um!! @42 cold you would measure approx. 46-47 hot but are you really at 80degrees tyre warmer temp?? I doubt it, closer to 65 degrees grab a piece of chalk, look at your rear tyre, outer 3rd of tread, can you see a wear line running around the circumference, where the light shade meets the dark shade draw and follow that line, its the line fairly even/smooth around the tyre? or is it like a child would draw the see at the horizon (smooth waves) or like sonic the hedgehogs hair (ripsaw cartoon style) if the later 2 then comp/rebound incorrect or shock oil needs servicing. if its fairly steady/smooth retaining a very similar distance from sidewall around circumference then your tear is more likely using all the torque from as early as poss on exit of corner, and that's called having fun!!:Wideyed: Remember wear patterns aren't a bad thing, they just leave an idea if its a bike issue or throttle use, always do what you can to eliminate bike wear then you can only bragg about your riding!!! If your running a heavily sipd tyres like PR4's then move to Angel GT's or similar, if your alreadyy running Angels then get another bike to enjoy it Better power deliverry and control!! Enjoy

Lol, I know wear patterns aren't a bad thing, but 2k miles and not even managing to finish a 10 day trip was rather a surprise (let alone the piss taking and beer penalties it cost me ) I fitted garmin tpms before this trip, and was seeing 49 to 51 psi in the rear, with up to 44 in the front. I suspected this was too high. Yup, it's an even line I get. Too much fun then I guess. I shall try angel gts next time, thanks :thumbsup:
