installed new dunlops on mk2 about 3000 miles ago and have noticeable thread wear on the rear only. if i didn't know any better, i'd say from burnouts, but that can't be. haven't measured the wear, but the front is looking good, almost new. NORMAL? what kind of mileage should i expect from modern day dunlops? at the rate the rear's going, looks like i'll be replacing it within the next 2000-3000 miles or so.
 
3k is all I get with any tyre on the back except the old style K70 or Avon Speedmassa. Their profile is also
rectangular and they have a lot more contact patch going straight ahead. No comment on the curves.
Front will go on forever. If I am really having a slow winter I will swap front to rear but why bother...
 
Torque. And riding it like a MOTORCYCLE, not a parade vehicle. Skinny contact patch. Replace them wearing a smile, because you are enjoying the ride!
 
I have about 3,100miles on 19x4.10 TT100s. They are wearing evenly, with plenty left. But, I don't ride on many straight roads, not many around where I live, mostly bends on country lanes. 26psi front 28 rear.
 
Joe you say it looks like it’s from burnouts?

Check for something that could rub on the tyre. Tyres grow at speed, and also think about the suspension being compressed.

Unless you’re just not being straight with us and your real name is ‘burnout Joe’…
 
The rear tyre puts the power onto the road and when you accelerate the weight transfer is onto the rear wheel. What would you expect to happen ? If you have enough power, you can ride the bike on it's rear wheel until you have to steer it.

nothing rubbing the tire and fairly sure suspension's not compromised. BTW, my real name is "burned out" Joe. :D

weight transfer - that makes sense - never gave it any thought. as far as enough power - more than adequate for my needs. i can say there is a definite difference between the Norton and my BSA Spitfire. guess the old saying's true - there's no substitute for cc's - ;)
 
Should get more than 3k miles out of your rear tyres, my Avons I get 13k km from the rear tyres on all my bikes that they are fitted, my tyre man has told me that modern tyres run a bit more pressure than the old ones, I stopped running K81s a long time ago the Avon RR are so much better and last a lot longer, well on my bikes anyway.

You get 13k km from rear Avon RRs ??
 
Several have mentioned tire pressure. Until recently I've stuck with 24psi as that's what the Triumphs I started on wanted (K70 tires). I finally looked up others and the Trident wanted 26/28 (TT100 tires), and the Avons, wanted more (see below). Also, as we age, we tend to get heavier and that implies a little more pressure IMHO. From Avon:

WHAT PRESSURES SHOULD I USE ON MY CLASSIC BIKE?
Due to the modern materials used in the construction of these tyres, we normally recommend 25-28 psi front and 28-34 psi rear.
 
I look at the wear on the rear and it is a pretty narrow strip wear wise no matter what size tyre so I guess the wide tyres are for looks or are for those who wear off the ends of the footrests. Not a fast rider but surely not a slow one and now that I am old hauling ass around a tight corner on a B road is not too wise. Tractors, cavalry and pushbikes can be in the middle of the lane
and it is your fault, not theirs, if you come to grief. Good brakes and good tyres matter but then so does sober thinking.
Honestly in awe if you can get some of the tyre mileage some claim and I am a featherweight and run low tyre pressure.
Nice day out intend to get some miles in!

Yes but they are right on the limit lol, on the old K81s I use to run 30psi in the rear and 28psi in the front with my modern tyres I run higher pressure on my Norton 36psi on the rear and 34psi in the front, on my 1200 Thruxton 41psi in the rear and 38psi in the front and I got 13k km from the rear and 24k km on the front with still plenty of tread left on the front (just replaced the front to match my new rear), the 1200 Thruxton has a lot more torque than the Norton, I am now running Metzellers dual purpose on the Thruxton fitted at 13K km and have just clocked over 20k km so far 7K km and they look like I will get a good run out of the rear only time will tell.
But the Thruxton does have Traction control but sometimes I do turn it off to have some fun and its always in sports mode.

Cry me a river, try keeping a rear tire on the Triumph Rocket III....:p Twice as expensive, and changing it is like alligator wrestling!

Sounds about typical if the roads are quite straight where you are. I had an Avon Super Venom that only went about 2500 miles. I have been running Bridgstone BT45/46's (hard center/soft sides) and can get about 5000 miles out of them. But square-warn tires are the norm here in SW Ontario...

Fronts will harden and weather crack before they ever wear out. I know folks that are still running 19's on both ends that "rotate" their tires for this reason (i.e. rear is worn out - put front on rear, put new tire on front)

FWIW
 
Does a great deal of engine braking affect the rear tire wear as opposed to just
using the rear brake?

All depends if it's gradual or RFN. The rubber cares not where the force is generated, brake drum, or the sprocket therein. That little 2" x 3" patch has to do it all.
