If you were running inexpensive tires on your bike and have enough experience with them then you might notice that the GP 5000 in any version ride much better. If you are in a area where there are thorns and other puncture hazards, then my might flat a little more often. But if you don't live in such area, then expect them to last a long time. Many flats, IMO are from incorrect installation or riding with too low a tire pressure for the bumps and other hazards encountered. So it's a good idea to learn how to diagnose why you flatted each and every time you flat.

I've been using GP 5000's for about five years maybe more. They ride very well and I haven't flatted in the last 3000 maybe 4000 miles I've ridden on them. I used to buy inexpensive tires and they were harsh riding and took a lot of leg muscle. My first pair of decent tires were Vittoria Rubino Pros. The difference in the ride and amount of leg muscle I used to move the bike was amazing to me. The GP 5000's I switched to seem to ride about the same as the Rubino Pros. But the GP 5000's seem to last a little longer.

I think if you hunted, you might have found the GP 5000's at a better price. Though it does depend on which version you purchased.
