LONG DISTANCE TYRES ???

The boss and I are planning next year's tour.It's going to be fairly lenghty and I was wondering if there may be a way to avoid changing the rear tyre (100/90/18)part way through the trip.Any recommendations for high mileage tyres chaps.

Dave, stop this madness before someone suggests an Avon SM.  You need maximum grip, particularly if the Vrsic Pass is on your agenda.  Settle for a pit stop half way round.  Are you going to share the route with us?

Wouldn't going to a 110/90/18 buy you a little more endurance ?
I regularly do well over 10.000 km on Avon RoadRiders, no madness involved, but also wouldn't
take anyone's advice on fitting THEIR favorite tyre before a long trip (or anytime, really).

Thanks for the replies chaps,lots of useful advice there.

Avon SM's wear very well, probably better than any and they are what I have been using without problems, even on the Vrsic Pass in the rain.However,I thought a more modern profile would improve cornering and general road holding, but they do tend to wear their centers out fairly quickly.
My experience this year in Sardinia and Corsica tends to make me want to avoid tyre fitters who don't know how to fit a tube and insist on fitting one valve stem nut outside of the rim AND THE OTHER INSIDE !!!
I haven't fully worked out the route yet, but we intend to tour the Peloponnese Peninsula. I'm expecting a round trip of seven to eight thousand miles.
I'm trying to get a grip Johnno. I see what you did there.
JPC, yes 110/90/18 is worth a thought.Road Riders,I get the impression that people don't care much for them ??
I used to use BT45's on my Laverda.They were good but 5000 miles was all I would get out of a rear.The bike will be heavily loaded which I think makes a difference to wear rates.

Dave, arrghhh, see what I mean ? RoadRiders, I swear by them, front & rear ! Smile

Very true, this problem with tyre fitters, a lot of the younger ones give you this
"thousand miles stare" when presented with an inner tube, and are visibly inept at fitting it.

Finally, one school of thought says that fitting one of the nuts on the inside prevents
stretching the rubber around the valve when tightening the outer one...

Fair points Dave all I can say is I once changed sport tyres to touring tyres on a Gsxr 750 k5  and after 3000 miles I binned them . Ruined the bike totally . Once on holiday  you want to enjoy your bike fully . 
Us guzzi chaps can sometimes be very helpful and sometimes a waste of time lol

For me this says it all regarding tube fitting.The steel washer at the base of the valve stem is shaped to fit into the rim well.This it cannot do if a nut is placed over the top of it. Putting a nut inside the rim is not only dangerous but potentially lethal.
The picture is from a Michelin website.It can be seen that the lower nut is not tightened against the rim (as I always used to do )but the two nuts are locked together leaving a gap between nut and rim allowing for slight misalignment or to show if tyre creep has occurred.

Steps off soap box to make tea.

Dave, on my Cali 1100i I use Metzeler ME880 Marathon front and rear tyres and I cannot fault them particularly with their minimal wear rate which was an important factor due to often using the bike abroad.

Worth a look.

I use Road Riders on my 850GT Dave. The last rear did 8000 miles, whereas the BT45 on the Spada only lasted 5000 miles. I'm not a fast rider so perhaps not the best judge, but can't tell the difference in performance. I occasionally touch the stand down on the 850GT, way before the tyre has reached its limit.

This could be better than an oil thread, as the net crawls with testimonies of one of the valve nuts
ALWAYS being found inside the rim of OEM mounted tube tyres !

I liked an observation that the most lethal of the nuts involved was the one holding the tyre iron LOL

Unfortunately the ME880 Metzeler isn't available in the required size for my rear wheel,100 or 110/90 /18. Thanks anyway Daryl.
Road Riders again, maybe the rumors are unfounded. So if they work well, and last well on your 850GT Ian, they should be right for mine. Thank you.

Well I love Roadriders - they give great grip in any conditions.  However I've never seen more than 3,000 miles from a rear tyre on either my V7 Sport or Ducati 900GTS.
