greetings all, results from an unscientific tire test.
In July I mounted a new PR4 rear tire on my LT at 78,400 miles.
I left on cross-country odyssey on 20 July and returned home on 21 Aug.
Mileage on odometer when I got home was 86,349.
total trip mileage was 7,949.
About 5,000 of those miles were 2-up, fully loaded luggage and traveling on Interstates. The remaining miles were cross-country solo ride w/loaded luggage via interstate.
The only twisty roads encountered were a couple of rides up and over the rockies in colorado, montana and alberta. these were sedately done as spouse was on board and she doesn't enjoy excessive lean-angles and scraping of scoot parts on asphalt.
Encountered about 5 days of rain over course of trip with one absolute downpour, tires performed flawlessly.
I'd say I still have a few thousand left on the tire and have been quite happy with performance.
I was a bit OCD regarding tire pressures, maintained 40 PSI rear and 34 PSI in front, checked and adjusted each morning to compensate for changes in temperatures.
i'd recommend the PR4 to anyone considering a tire change.
attached before and after pictures with odometer readings for the nay-sayers.
