Me: Almost exclusively pavement, 5'10", 190lbs. Figured I'd give some stats on the GP4000 that I have on the rear of my Lynskey
1) what tire size and PSI do/did you use?
GP4000 SII, 25mm, 90PSI
2) how many total miles did you get (tubeless or non) before trashing them?
~2170 miles so far, all but 6 of them on pavement. Only recently started showing some squaring off.
3) how many flats did you get? (pls specify front or rear if you recall)
No flats yet
4) how would you describe the road surfaces where you ride?
First 1300 miles: fairly smooth asphalt, not much chipseal
Most recent ~900 miles: fresh rail-trail pavement, very smooth.
5) anything else you'd like to add
My Rubinos and Zaffiros seemed to square off as soon as they were mounted - I even had a shop tell me it was time to replace the tire that I'd put on two months prior (maybe 3-400 miles). The GP4k seems like a great value in that regard.
