Greetings,
Toward start of season, I put on a set of PR3s. I bought mine from www.tiresunlimited.com, $317 to my door. Comp. Accessories was about $20 less at the time, but I've used the TU guys for a decade now and their willingness to please is appreciated.
I have around 8,500 on my pair now. I'm primarily a flat-lander with trips for curves thrown in
. Starting with 6mm (new/rear), at 8,000 I measured 3mm tread depth, center of tire. The tread wear indicators are about 1.5mm in depth. At 8,000miles and 3mm wear, that's about 2600 miles/mm. With 1.5mm before hitting the TWI's, I should theoretically get another 4,000. Given that tires seem to accelerate their wear later in life, and given what I'm visually observing, my guess is I'll be somewhere around 10,500 for the rear. Front's doing good, good enough I've not bothered trying to forecast it.
The PR3s have proven an excellent all-rounder. They've got good traction. Traction in the wet is good. Overall they're confidence inspiring and give a good quality ride.
Caveats: The tread pattern in the front, which I attribute in good measure to wet weather handling, generates a bit of a hum. Nothing like a truck-tire hum, but there. Its nothing that will keep me from buying another set, just mentioning so you're not surprised. That said, given the smaller tread blocks up front, there's minimal cupping which has not progressed past what I noted after about the 1K mark.
The other thing I have noticed is air pressure. I've asked other PR3 owners about this--non FJR owners as well. All the tires I've ever bough for cast rims (e.g. tubeless), I could put air in and not need to touch again for months. Yes, I'd check, but perhaps only every 6 weeks or so. The PR3s, in comparison, must be very porous. They loose (front and rear, both) about 1-1.5 PSI/week. I routinely check my tires more or less weekly now. Went on a 2 week family trip, came home, 3 weeks from last check and they were down 4 PSI front, 7 PSI rear. So, it seems, buy PR3s, plan on having access to an air compressor too.
