1) alumnum bike with 700x28C tires on aluminum rims, Continental GP5000 with inner tubes @ 80 psi front and rear.
2) The ride is pretty harsh
3) Continental Gatorskins for the commute
4) wider tire and lower pressure.
5) I want to stick with inner tubes, can I ride lower pressures (60 psi?)
1) 80 psi with that setup is way too high pressure. The reason one chooses wider tires, is to lower the pressure without getting pinch flats. ATM I'm riding 26 mm tires (only because of lack of clearance, otherwise I would go 28 mm), and I never ride with more than 60 psi. Sometimes even 55 psi, and I'm 90 kg. So the first suggestion would be; lower the pressure to 50-60 psi, and check out how it feels.
2) because of too high pressure.
3) The thing is, if you want something that is more puncture resistant, the tire company adds more kevlar (or other tech, that prevents objects to penetrate the tire) and more rubber. Both which take away the plushness and comfort of the tire. So puncture protection and plushness are counter productive.
4) This is the way to go.
5) Easily
If you want more puncture resistance, I can really recommend Pirelli CInturato road. You can ride it both with tubes and tubeless. I have done both with good results. Of all the tires mentioned in the topic Conti 4 Seasons, Conti GP 5000 All Seasons, Marathon (this tire is heavy AF) and GP5000; Pirelli Cinturato is one of the best tires for puncture protection, and it is still reasonably fast and plush.
I live in the northern parts of EU, so at this time of year we have rain all the time. Puncture protection is all I ever think about, but comfort is a close 2nd. I have tried all the mentioned tires and I've ridden everything between 23 mm and 35 mm. Some of the tires I have ridden in several widths. The 5000 I own in 23, 25, 28, Conti 3 Seasons in 23, 25, 28, 32. Cinturato 24, 26, 28. And my conclusion is, if you want puncture protection and comfort go Pirelli in 26 or 28, maybe even 32 or 35. If you want speed go 5000.
