Have never used the PR2/3's, but my PR4GT's are nearly worn out now (especially the rear), I am at about 15,000 miles and they still handle great. So "your mileage may vary" I will be replacing them with 4GT again.
Wow, Max! I'm jealous! Lol...
I dunno why my set of 4 GT's cratered so soon. I was all set to finally see 15k out of them.
I figured if their extra life claims worked for me in the real world, they'd be worth the extra bucks...
I kept the air pressures at 42 psi cold...
I rode NO twisties.
I rode NO 2 up.
I carried no trunk, or heavy gear in the bags.
I babied the throttle their entire life, like a senior citizen headed to Sunday church...
... things I've never done with any set of PR2's. I consistantly average 12k out of 2's.
End result for all my "disciplined, uber-conservative" behaviour...(ie; no fun...) 8k miles.
Beats me? IIRC, that set of 4GT's cost me around $425.
This last set of 2's cost me $310.
This set's the first 180/55 rear I've tried. So far, no complaints. It works fine, saves some bucks.
I gave them a shot based on a few others' positive experiences, and I agree.
I called Michelin a while back and spoke to a nice lady, asked her why they recommend the GT over the standard 4 because the standard 4 has 2 ply sidewalls, 4GT's have one...etc.
She couldn't answer ANY of my questions, and no one ever called me back.
I was disappointed in their longevity and high price. Liked everything else about them, though.
Maybe just bad luck with this particular set...?
I may give the Angel GT A specs a try this summer when I wear this set of 2's out.
So... What's the secret to your success, Max? Do anything special that I didn't do to get 15k??
