Tire recommendations

[beemuker]

Have you checked with your local BMW motorcycle club to see if anyone has a tire changer? 


I have a No-Mar tire changer and a Marc Parnes [size=78%]http://www.marcparnes.com/BMW_Motorcycle_Wheel_Balancer.htm[/size] balancer kit that I offer for any of our club members that wish to save a few $$ and do tire changes without the scheduling hassle.

I'm in Hardly Ableson land here. As far as I know no local club. My friend with a Guzzi does his own without a machine. I'm just happy I found someone to do it at a reasonable price.

I have a NoMar unit in my house & a balancing rig if anyone is near NYC, I would be happy to help )) :riding:

So, steering this thread back to tires for a moment...Anyone here tried the Pirelli Angle GT tires?

https://www.bikebandit.com/tires-tubes/motorcycle-tires/pirelli-angel-gt-motorcycle-tire/p/41920?m=10939

Bike Bandit has them in K1100 LT usable sizes. The price is cheaper than the Metzler PR series.

My newly installed Michelin Activs are 1/2 worn out after 3,000 miles. Probably go another 2,000. Not a good deal by any means, especially when installation costs are factored in.

The Pirelli's are radial tires with a W rating (168 MPH+).

So, has anyone used these tires? I'm esp. interested in handling + mileage info.
The savings are about $80 for the set over the new PR4's.

don't know about the "Angle GT's"  but the Angel GT's seem to get great reviews on various Beemer forums...

I just bought a set for my bike, will be here Friday.


I have used them on a couple Buell's.


They were pretty nice tires so I figured I'd try them out again. )

[K100Pilot]

PS. I ordered them from Dennis Kirk, even a little bit cheaper there ))

[beemrdon]

Pirelli markets them as sport touring tires. They come in 110/80/18 front and 150/70/15 for the rear, which is what I use in the Michelin PRs. I think I read that they are dual compound too

I'm no tire-ninja, but just to make something sure before go buying tires:
On a K75C '87, which comes with a rear rim sizing 2.75"-18", I could put a 17" TL tire on it?


(for the record, I'm specifically looking at Front 110/80-18"TL and Rear 140/80-17" TL of either the TKC80 or Heidenau K60)

 :eek: REALLY?!?! :nono No you cannot!  A 17 inch tire will not mount on an 18 inch rim!

The 110/80-18 Scout will need a tube fitted for mounting. Heidenau does not list a tubeless (TL) in that size, only a tube-type (TT).

Both TKC80 sizes are TL, if available.

He could always try a pre-mounting dip of the rim in liquid nitrogen then mounting the tire after heating it in a pizza oven.

I also have an 87 K75C. My 120/90-18 rear tire barely clears a side stand bracket. I question whether a 140 would. I like my Shinko 712s.

Got it, thanks guys.

I've seen alot of scrambler-type K's which have these tires on. Maybe the clearing differs between K100 en K75?

Bingo!  :clap:

[beemrdon]

If he were a "tire Ninja" he might be able to karate-chop the tire onto the rim....Hiiiii-ya!!! :cowpoop:

[Brad-Man]

I see that Continental has Conti Road Attack 3 radials for front and rear for the Y spoke K75/K100 2v rims - 100/90 and 110/80 18 fronts and 130/80-17 and 130/80-18 rear sizes.

Might have to try them.

Hey Yawl,
Will a 120/70/18 fit on my 94K1100 front wheel? There doesn't seem to be a lot of extra width up front.
I am getting ready to order tires for the upcoming season soon to start here in VT. I am sold on the Michelin  P R series.  Great handling, and long lasting. I have over 9k on the P R 3's now on my bike, and some to go.  I will probably get 10k out of them.  More than twice the wear of most tires I have used.  Well worth the extra $$!   Do you know for a fact that the 120/70/18 will not be to wide for my 94K1100?? There does not seem to be much extra width up front!  Just wondering if anyone has actually mounted that size tire on your bike? Or if you are sure they will fit, and not rub?  Funny why Michelin had the 110/80/18 in the PR3, but it is not offered in the PR4?
Thanks,
Bizz

. . . the upcoming season soon to start here in VT.

Really? It won't be soon where I live, Biz, unless global warming gets a move on, pulls the frost from this road and dries it to an attractive patina. I'll just need to be content watching curling match replays until then.

[bizzaro]

 :2thumbup: For The Curling.  My Brother and I had to walk and talk lightly at our curling club in Sutton Quebec last night after the  U S beat Canada twice in curling, and just won the gold in hockey by beating the Canadian Women's Hockey Team!!! :yow :yow   Really it is all good.  Nice and friendly folks at curling club all around. But there was not the usual zealous hockey or curling banter last night! :giggles

I will be on the road by the end of March  :2thumbup: .................Just around the corner,  while your anxiously awaiting  the frost heaves and mud to subside.  One of the advantages of living close to the pavement in these clime's! :neener: The other day when it hit 70, that's all I could think about.  If I hadn't have drained my coolant, I probably would have gone and got my bike out of storage and had it weather out these last few weeks of Winter, in my wood shed now that there is room in there! :hehehe Just in case I could get a ride in on the next thaw day! :2thumbup:

Back on Subject:  WILL A 120/70/18 FIT ON A K1100LT and not rub the calipers or fender/forks?? (just thought maybe I should highlight the question! :eek: )

[Laitch]

There's precious little specific info out there. You might be the pioneer with this one, Biz, unless you wait until beemerdon tackles the issue in April or May. A 120/60 will fit on your front rim. It would be a width increase of 10mm compared with your current tire. That's roughly a 5mm increase on each side. If your bike has more clearance from the sliders than that, it might work. A straight-edge measuring rule would be all you need.

What I'd want to know is how much expansion of width occurs when the tire you have now is hot. I'd use that number to determine how much clearance you might need for the new tire. 

You intend to transport a deer on the front fender this fall?

[beemrdon]

Hey there Bizz... The difference between a 110 and a 120 width is 5 millimeters on each side.
 Looks like more than enough room to me. I will be buying one in a couple of thousand more miles when present tires are shot.
Let us know how it works out if you go first.

[beemerphile]

You might be the pioneer with this one, Biz,

Remember that the pioneer is the guy with an arrow in his chest.  Whether it will fit is not the question so much as how well it will work.  Motorcycles are designed from the tires up.  As soon as you change the tire size, you are now the motorcycle's designer.  You change rake, trail, unsprung wright, etc, in so doing.  Good luck doing it as well as the building full of brainy smurfs who did it the first time.


I don't have much K bike seat time, but in the airhead community "how big a tire will fit" is often asked and tried.  In every case where larger tires were fitted, the handling suffered.  3.50's where 3.25's were called out and 100/90's where 90/90's were called out.  120/90's on the rear where 4.00's were called out.  Disasters one and all.

What is the rim size called for to fit the wider tire? 

When you fit a wider tire that is designed for a wider rim you end up distorting the profile which will effect how the bike falls into turns.  It can also REDUCE the size of the contact patch which will reduce traction and stopping power.

Yuri Gagarin probably would dispute that, if he were still alive.
