Any of you who have a big bore two stroke(500cc), what do you run for the rear tire?
The old standard was to use a 5.10 x 18 but that does not seem to be available anymore.

Of course, I do ride in very different areas / conditions to most 500 riders. It's so rare that I use a knobby nowadays, and I've a variety of 140 sized Michelins and Pirellis languishing in my workshop, if I were to throw a knobby back on.
Whatever type of tyre used - a 2.5" rim is a wonderful thing on 450s / 500s.

How do those Terra Flex tires actually work, in the desert or on a motocross track.
...don't like the front....at all.
You don't need anything special when it comes to tires. It's not like a 2-Stroke 500 is some kind of beast rocket.
Just run whatever tire you normally run, in a 120/XX size. You need to learn throttle control. A big flywheel weight helps also.
I rode KX500s for years.
Works great on my WR 500

This is from Interco, when I contacted them yesterday...
What’s the difference between Style 1 and Style 2?
Tread design style 1 and tread design style 2 as shown on web site.
Tread style 2 ; only available in 140/80-18 and 140/90-17 sizes, recommended rim width 3.5”
Tread style 1 ; only available in 110/100-18 size, recommended rim width 2.15” / 2,5”
On a 2000 CR500, would I have clearance issues running the Style 2? Would the recommended 3.5” wheel cause any clearance issues?

You, sir, are a real man if that's your honest opinion.
You don't have to slam the throttle wide open - well, you do that, and you will tend to be in deep s**t on a 500, or indeed, a 450 and up modern day 4t.
500 2ts are Torquey things, far, far more than 4ts, it's just the near vertical HP graph that gets you. From 0 revs to lucky to be 6K revs, where a 500 2t tends to sign off, is a somewhat more 'abrupt' power delivery than a modern 4t that tends to have max power ( and quite a few now with higher HP figures than a 500 2t) around the 9 / 10K.
In reality, said Michelin, is so bloody sticky, it gets heaps of traction. And, in my local area, which is rock ledge and rock base - plus Sand, it works beautifully.
But, the far scarier thing than breaking loose under power, is the way a Trials tyre can just sliiiiiiiiide along downhill, on dirt, as there are no knobs to 'catch' on things
I've no problem with the wear rate of soft, Gummy tyres - it's a Safety thing, on the old beast. And I need all the Safety I can get, in my 7th decade on this mud / dust ball!
I looked at my 465 and I guess you could get a Terra Flex in there. I'm surprised they are still available. I would thing that as heavy as there and with steel belts your back end would fell kind of dead back there.
Throttle control is not a bad thing.
In all honesty I never did find them that intimidating.
