What Tires do you Run

I was wondering if it was a tube friction failure issue or carcass heating from tube squirm friction issue... etc

That may be the source of extra heat. Here's a link that states "Also, when using a tube in a tubeless tire you should downgrade the speed rating by one to compensate for the increased heat due to friction between the tube and the tire carcass."

Here's another that mentions heat as the reason for reducing the speed rating:

If u hit 140 on a KZ ...u actually doing around 125.
U hit 160 you are around 140mph
No need for V Rated Tiires unless u doing some kind of racing.

Used Pirelli Dragons on the YZF 750 i had - dont know if they even make them now- brilliant tyres but spent $2000 in 14 months on them so got rid of that bike - far too expensive to run.

I know the feeling! Way back in the late '70's I was running Michelin tires with the PZ2 compound. I could put 1,000 miles on the rear; 2,000 miles on the front before they were shot. Back then I was running 6,000 miles a year, and at $100 per tire I was spending $900 per year on tires. After 2 years I came to my senses and stopped running the racing compound on the street, Too much money, but man, those tires really did stick to the road like glue! Ed

Thats crazy low mileage Ed - they would have been incredible tyres alright - i did considerably better out of the Dragons but still only a few 1000.Other things like an air filter being $120 and all the crap i had to take off to get at anything kinda killed the sports bike enthusiasm - oh and it was too uncomfortable as well- went ok though - had it up to 255 km/h but it wasnt a Kawasaki .

are you doing burnouts everywhere you go? I have gone through several sets of 712's and usually get about 8k on the rear, 12k on the front. although the last rear tire I rode down to the steel.

No joke, I put 6000 at least on mine and they still look new...but I ride like an old man. Lol

5k launches, small wheelies, downshifting, and lots of twisty roads and your tires wear down pretty quickly. I'm also riding in a lot of stop n go traffic (inner city in Memphis), and I tend to like to accelerate quickly (which leads to breaking more quickly), so my tires wear out pretty quick. Even with good tires, I usually last less than 5,000 miles on the rear, and usually 10,000+ on the front, with a good tire, like the dunlop gt501.

Also, I usually change tires, as soon as my tread is down to 1/16" or less, on atleast 60% of the tire. So, I may still have a few hundred miles of life, but with the way I ride, I change tires frequently.

Never seen the sense in burnouts - what does it achieve really. Even watching someone gets old very quickly. Let them twisties wear em down i reckon. No city stuff - takes me a minute to get out on the highway . Never had 1 down to steel. Bit like my oil changes - probably change before i need to but makes me very confident

I have about 1100 miles on my new Shinko 712 tires.... so far, my little Auto Zone tire depth gauge, stuck as close to dead center as I can on the rear tire says ...I have dropped about a 1/32" from when new.... that sounds like at least a 7000-8000 mile tire to me if I don't hot dog it too much. And out here in the Denver area... it is all straight line driving but in mountains... there are no straight roads and a blast to cruise through about 10mph-15mph over the flat lander's, sissy speeds for tourists.

I'm also running Shinkos. F 230 in front and 712 in the rear. Big improvement over Dunlop 404s (and runflats, obviously). I find them to be a very reasonable cost/longevity/performance compromise.
