Title: New Tyres please
Post by: BeeJay on 2019-01-02 17:00:01
Managed 7k miles on the oem PR4 GT tyres that came with the bike in April (last year).
No problems with them except serious cupping on the front, same as I had on my previous 2014 RT.
Changing to Metzeler 01s, as I did on my previous bike with no cupping then.
Going to Chester tomorrow pm to get them fitted for £299.58.
Whilst we're there SWMBO is going to try a R1200RS. Trying to put her off buying the new 1250 (lol)
Take care one and all and ride safe

I'm close to needing a new set for mine and still confused as to which ones to get and where to get them from.
The PR5 GT's may be out by then ..

7k! Out of PR4GT's?
I think you should pay more attention to the standard of your riding rather than questioning which tyre brand compliments poor rider skills. Happy new year 👍

A lot depends on when to change tyres. Perhaps I change them earlier than others.
The main thing is that I enjoy riding the bike and if it means I change the tyres  more often then that's  a price I'm willing to pay.
It's a superb bike and I love riding it hard (well). North Wales roads are all about enjoying the bike and having fun, safely.
Back in the days when I had a Pan, a guy I knew used to get a lot more mikes from his tyres than I did. But it took him ages to get anywhere.
It all comes down to personal choice. That's the great thing about riding.

Not sure I get how to take this:-) are you suggesting 7K is a too much or a too little?  Peter

Tyre choice is a very subjective choice. I normally bank on 6-7k max for a set of tyres before I change, I never run them down to the legal limit. A Michelin Tech told me years ago to run the PR4GT at 38 on the front and that helps massively with cupping. If you think about it, one tyre pressure for all makes of tyres on a bike, doesn't make sense, the tyre manufacturer is the best people to advise on pressures :)

A rather vague comment me thinks. Anyway I run PR4GTs on my 14 RT and get about 7K out of them and they are then squared off at the front and the back is down to 1 mm. Interestingly my heavier Pan with the same tyres I get 8K. I probably ride the RT harder than the Pan but I think the extra milage out of the much heavier Pan is down to the smoother V4 power delivery. Selling the Pan this year anyone interested ?

Measured the tread:
Front - middle 2.0 : outer 2.5
Rear -  middle 2.0 : outer 4.0
Cupping on both front and rear with a very decent "chicken strip".


Very difficult to avoid centre wearing quicker, Germany and back was mostly "upright" and 1500mile around Scotlaqnd took it's toll.
Overall, I'm satisfied with how long the tyres last for my style of riding.

Same with me, in the scheme of things tyres are not expensive for a motorcycle, and they are pretty important, so I will continue to change them if they start to square off or lose grip, regardless of mileage completed :)

I'm with Casbar on this one.  Once the tyres start to feel bad they go, so that is usually 7-8k on a pair of PR4GTs.  I'd rather suck up the £30 quid cost of the rubber I could have used on screwing the last few miles out of them and enjoy the new ones.  Looking forward to trying the Road 5s.  One day......
Title: Re: New Tyres please
Post by: stayingupright on 2019-01-03 13:09:01
I'm going to be changing mine at about 8k.

Guess I need to look at the standard of my riding as well then! .... But we all knew that anyway, right?

I better check my standard of riding or loose a lot of weight......I only get about 5k on a set of PR4's

Post by: gogs01 on 2019-01-03 14:45:13
I'm another one not sure about the "standard of riding" comment.
I can get more than 7 or 8k out of my PR4GTs - much more from a front.  I often change tyres early if I'm planning a big trip.
Maybe my trips are significant - I like to visit some of the less frequented countries of Eastern / Northern Europe where speed limits can be low (when avoiding motorways) and where I don't want to be having a conversation with any officers of the law.
Maybe that helps with tyre wear, but I've also used German autobahns including a lap of the Nurburgring and still got great mileage out of my tyres.
I've also never noticed "cupping" - I thought that was an American issue.

My comment certainly stoked the embers lol, No offence BeeJay (Barry) and I offer my apologies! It was just a bit of mischievousness on my behalf and I'm sure you're a very good rider! Just like all us RT riders!  (https://i.imgur.com/bH34QDt.gif) Anyway, Going back to tyre choice? I'd have be inclined to go with the PR4GT's again going off the posts in this thread, Good dry grip, good wet grip, and an average life span of between 5 to 8k miles dependent of how heavy you are with your wrist and braking fingers & toes. I'll be interested to hear your opinions on the Metzelers after a few K miles? It was a tyre I was very tempted with when I opted for the PR4's again.

PS. How was the RS?
Title: Re: New Tyres please
Post by: BeeJay on 2019-01-03 23:19:32
No offence taken, just don't cross the road in front of me, lol.
I had the Metz 01s on my previous RT for about 6k miles and was extremely happy with the wear, no cupping at all.
As for the RS, a no-go. Anne's been used to VFR, 18years, and her latest CBR650F, 18months, and found it a bit "big" and was worried about the "pots" sticking out, tried the R, naked version of the RS, still daunted about cylinders sticking out and found it a bit of a reach to the handlebars. Risers may solve that issue but you have to buy the bike and risers just to try it.
I'll try and get her to try a boxer when the weather warms a bit. She has until July when her 2 year warranty finishes.
She likes the CBR, ridden just over 5k miles last year.
On a brighter side, it saved me about £10k.

I only got 2K out of a rear Dunlop on my K1100LT mostly 2up. It was back in the ‘80s.


The Metzlers on mine have done 1700 mls and hardly worn. Really like em. But dont ride in wet so cant comment on that.

Cupping I think is due to heavy braking.

Braking can impact cupping, but under inflation and loading also plays a factor. Like I said if you speak to Michelin tech and use PR4GT, put a couple of more pounds in and the cupping doesn't happen. Have only used PR4GTs in the last 18k miles and the first set cupped, none have since then, and I don't think I've changed the way I brake.
Title: Re: New Tyres please
Post by: Peter Baker on 2019-01-05 00:36:33
I have never seen more than 5-6K out of rear PR4GTs on K1600/R1200/K1300S and the same more recently on Roadtec01s. I guess that eliminates the bike then:-) as some above say, it is a choice, I'm not mad but I like to "go" when out of the built up areas.  I am a lifetime PR2/3/4/4GT fan on a variety of bikes, however after the MCN tests saying "PR.. is a great tyre but Roadtec01 is better" I had to try them, and for me they are.  PR3/4s go round corners easy, but if you want the last few degrees in my mind you have to work at it, the Roadtec01s just role in asking for more and more...  I just can't get enough of them, plus I think I get about another 500 miles (10% woo hoo!) out of them before they start to feel "off".  Technology moves on, who knows I might be back to PR5s some day!  Peter

Hi


I got almost 10k Miles out of the original PR4s  they were still legal but not good for riding on when I changed to Roadtec 01s


I have found I get more feedback from the 01s  you know when your near the limit,  with the PR4s I found suddenly I was past the limits and thinking oh shit :eek:

Looking at the BMW recommended tyre options, Metzeler Z8 or Michelin PR 4GT are only listed for both the 1200 & the new 1250.
Title: Re: New Tyres please

There is a thread running on UKGSER about tyres and grip in the Winter. Apparently Roadtec 01 are listed as a summer tyre. Not sure what that actually means as regards to winter in the UK though.

Summer tyres ?  Winter tyres ?  For motorcycles ??   :o


Cars in UK come fitted, almost exclusively, with Summer tyres.  These tyres can be replaced with Winter tyres and this is recommended by motoring associations when temperatures are likely to fall below seven degrees celsius (and if you're going to visit certain European countries in the winter months)


All season tyres are also available, most of which are based on Winter tyre design & construction.  The downsides of running these tyres all year probably include less than best in class grip on hot dry tarmac and higher than average wear rates.  I'll see if that's the case with my Goodyear Vector 4 Seasons.....


As for bike tyres, the mileage I do in temperatures below seven degrees celsius would not justify using anything other than "Summer" tyres (assuming anything else is available).   ;D

The Metzeler Feelfree Wintec has the same tread pattern as the Feelfree with the application of sipes.

Now just £213.44 for the pair... I may have to order soon.


With over 10k on my original 2012 tyres, they're probably due a change. That said, there's plenty of tread in them still.

I am keeping a close eye on my tyres now they're close to 10k, but they're still performing well and have loads of even tread left.


The price for a pair of 4GTs is down to £208 now, but I can't justify that until I NEED them.
