Maybe that's the secret to tyre longevity - just keep it pinned and the kinetic energy of ya rear just bulldozers through everything , runs that hot
melts everything in its path without much detriment to itself![]()
Oh if that were true!
Points for wishful thinking but.

Secret is Sand
About once or twice a mouth I head from home to Murawai beach 90ks round trip, then I head up beach to South head, drop tire pressures to about 20psi and climb the dunes, sit at the top a drink a V and munch on a peanut slab and return to gas station pump up tires and back home, 110 ks round trip, do some other trips with a bit more seal than sand with some metal but not often (Rimmers road via beach)
So I'm guessing 2500ks on road 1500 on sand (no point in thrashing bike on way to beach except in corners where tire is on it side so not to much wear and Sand is near zero wear so running up the beach at between 100 - 150kph and then up the dunes is cheap in tire cost
Just love the Desolateness of it all at South Head and am often on my own up there in the morning before all the 4WD guys arrive (in the Winter cold or rain still do the trip but in 4wd with heater on, think those tires will last 40,000 ks

OK you tyre Gurus, Ive finally managed to grace my shed with a DR650, Its got an EO7 on the rearand a Dunlop 605 on the front which at 22 psi has got a noticeable bulge when im perched on it, (Im only 100KG). Suzi recommend 22 psi but it seems a bit soft.
Is the 605 a naturally soft tyre or is the tyre telling me its past its use by date, its still got good tread on it.
The only other thing is, when i got it home, the front had only 14psi in it and the back had 17psi. the previous owner had been using it as a commuter bike for work so it may have done a lot of ks at low pressure and buggered the compound of the tyre.
Cheers

it should be ok, but if you're not sure strip down the rear & make sure the tyre wall is not damaged, if it's any help I run Eo7's on the 1150 which weighs 250kg wet then you can add 20kgs for gear & me 129kg & I run 20/18 unless I'm on a road trip then 30/30 & I've had no probs with them

Road use, I'd be looking at 26f/28r for that tyre combo.
Seal/gravel, more toward 22f/24r.
Off road, around 20f/18r.
These assume no luggage, or only a small backpack.
If the tubes are holding air then the low pressures shouldn't have had and deleterious effect on the tyre carcass, just accelerated wear on the tread.
Are road tires must be different to trail tires ??
Heat is the big wear factor for the road so Ideal pressures for 1000cc bikes for wear (rear tires) 38-42 psi, when we drop them to 28-30 for track days they get hotter grip better but wear a lot faster (not to mention the thrashing they are getting)
Its stands to reason ? that if you run lower pressures on trail tires on the road the same thing will happen, they will get hotter and softer and wear faster (spending more of your money)
I noticed this some years ago that by adding 5-10 psi to my sloppy 25 psi pressures, Tire wear on the road reduced considerable over the life the tire.
I run these rear pressure now on road DRBIG 32-34psi, KTM950 37-38 and reduce front by 2-4 psi getting very good tire life, even with spirited riding at times
Means more fiddling at gas stations and with tire gauges on the trail but better for the pocket
I'd rather be pelted by sand than gravel and stones,
IMHO You wont get better off-road grip (at 15-20 psi) but be prepare for unusual turn in on road as not a very rounded profile (at 30+ psi of course), I think its fun and compensate by leaning off the bike, but it takes a little getting used to
Added bonus is that you don't need music as tires sing nicely![]()
