    I've ordered an MT43 for the 690.

    Keen to prolong the life of the tyre as much as possible ...

    One discussion (somewhere) talked about wearing MT43s down more quickly when running them at about 15psi (i.e. at a higher pressure than the usual 6-10psi) - is this correct? - I would have thought the opposite ...

    My concern is for the long open dirt roads (very hard - exposed rock in places) which you tend to travel at around 100kph - don't want to shred the tyres ...

    I've been using the MT43 rear tires on my WR250R for more than a year now and have been extremely pleased with both performance and tread life. One unique feature that impressed me was that these tires perform almost as well on the last few hundred miles of tread as when new. With the D606s and T63s I'd used previously on the bike once a third to half the tread was gone their off-road performance fell off sharply. I'm averaging around 3K miles on these rear tires and will be putting my fourth one on in a week or two. I pretty much leave the pressure at 12 psi all the time and run the lightweight MotionPro rim lock.

    I'm not using the MT43 on the front because I want a little more bite and have had good luck with the D606 front. Next time, however, I'm going to a MT21 front because it can be turned around halfway thru its tread life to get more mileage. The D606 is directional by design and when I reversed one the bike began dancing around uncomfortably for me on gravel roads. I'm expecting to get two rears to one front (around 6K miles total) with this new combo. With the MT43 rear/D606 front I'd get about 1.5 rears to one front.

    YRMV.

    Many thanks - I'll stick in about 12-15psi and see how it behaves / wears - the 690 is hard on rear tyres - the gravel roads more so than the tar I think, and a big part of the enjoyment of the bike - I run an MT21 on the front, and find that about spot-on - very similar to the D606.

    I've just put one on the back of my 2012 690, and at only 250km the centre tread seems to be coming apart ...

    I'm running it at 18psi in, as this first run was mostly hard gravel with a bit of tar - and a lot of it at speed ...

    Should I be running a lower pressure on these surfaces ... ?

    Tyre doesn't look as though it will last very long at this rate ... <!-- / message -->

    I run one on the rear of my Aprilia RXV. This bike will destroy knobbies in two rides here in AZ. I've got 1500 on the MT43 and it's barely showing wear. Its been super grippy at 7psi with a Tubliss setup. I have noticed that if you stop in sand or mud it can me a chore to get rolling again. Otherwise riding on those surfaces it great. If you like flat-tracking on fire roads, you can, but there are limits and the limit is pretty abrupt. If you understand how the tire is designed to be used, this shouldn't be any surprise.

    Do you run it at 7psi all the time?

    That is, for hard gravel / fire trails and any transport legs on the tar?

    Just for the gnarly stuff. 10psi on the stuff you mention.

    This is why I won't use one on a bike that's primarily a dual sport, as I had the same issues. If I ever turn my WR in to a trail machine, which is probably sooner than later, I might try the MT43 again. 5-8psi off-road, using the tall sidewall to protect your rims from rocks instead of air pressure, and there's not much it won't grip on. Great if the terrain is truly snotty, and especially so if you're more of a "point and shoot" rider than a "drift the rear end around sliding through the corners" type rider you'll love it.

    MT43's almost doesn't wear off-road, they're really durable on trails, and even better they don't dig in and rip up the trails meaning things are left in better conditions for the next rider. Above 12psi, you lose most of the benefits of the trials tire because its too stiff to flex and grip like its supposed to, but at least wears reasonably well on the street. Above 15psi, I think you'll find it burns the center knobs off extremely quickly on pavement.


    I prefer to slide around more, think I still have tremendous amounts of off-road grip when run at 10-15psi and can rail paved corners at the higher pressures, prefer the shorter overall height, and get better mileage (upwards of 7500 miles, usually toss them at 5000-5500 miles) from a D606 rear, so I'll keep using them until they stop making them.

    I put another 500km on it on a ride last week.

    Mostly hard gravel roads at speed - with 690 weight / acceleration / braking / etc ...

    They definitely wear less when you drop the pressure back to about 12psi, and I have to say that I like the feeling - predictable loss of traction in corners - very stable ...

    I'll run them through till about 1500km, then post some pics and a review - the 690 is pretty punishing on back tyres, and a good acid test for dual-sport capability ...

    I'm curious, what pressures were you running in the D606 rear to get that kind of mileage? I've run two or three on my WR-R and have found they're pretty much gone for off-road use (1/8" of knob left in the center) after 1,800 or 2,000 miles. Sure, they were still rideable on the street, for a few hundred more miles, but didn't hook up in the dirt. I usually ran around 15 psi off-road (no rim lock) and aired up to 20-25 on the pavement.

    Conversely, I find I'm consistently getting 3K miles from the MT43s running 12 psi with rim lock for everything, unless I get into a situation where I need to air down. The big difference for me is the Pirellis seem to grip about as well when nearly gone as when new.

    I've never got more than 3,000km (1800 miles) out of a D606 rear tyre, and don't know anyone who does ...

    If I can get the same from the MT43 I'll be happy, but not looking likely a this point ...

    About the same pressures, honestly... maybe a bit higher on the street since I was usually loaded for a trip. 12-15psi off-road, 20-30psi on, never really kept too much track of it as the OE tubes I used didn't leak much if any air so I didn't check them all that often. Typically when traveling I'd run them at 25psi+ as I was going for maximum wear and road use vs max traction off-road.

    Here's the one that ran for 7000 miles, and yeah... it's WORN out.

    This one had about 5000 miles on it and was still working ok on the TAT back in 2009 when I pulled it off at HighFive's house.

    Boy oh boy do they HOWL though when they get that old, I can hear them over my FMF powercore pipe. :eek1 The MT43's are definitely quieter.
