Tire suggestions Giant Cypress

i have a 2016 Giant Cypress with Kenda 700/38 tires. They are wearing some and I don't like the 80 psi. Tried to run lower psi and ended up with a pinch flat. Looking for suggestions for a lower psi, more comfortable riding tire. Ride mostly paved bike trails with some gravel. Any ideas?

Schwalbe Marathon Green Guard. Good flat protection but not so tough that it spoils the ride.

The answer to more comfort and lower pressure is wider tires, up to as big as your bike will fit.

Yeah, you generally want as large a tire as you can fit. A Cypress can possibly handle up to 42mm or 45mm wide. Your closest clearance will probably be in the rear, at the seatstay or the chainstay. See if you think your frame can take an extra 5-10mm there. Remember that both the tire width and diameter will grow with larger tires, so measure accordingly. Height probably won't be a problem, except for possibly at the chainstay -- you may have a kickstand plate or a fender mount down there that may limit the tire's diameter. Your front tire should have plenty of clearance for whatever size you want.

Two related questions:
  1. Do you have fenders or mudguards? These can limit tire clearance.
  2. Does your Cypress have disc brakes? If so, you could go to the extreme and change your wheels to 27.5" wheels and run perhaps a 27.5x2" tire. That would be a wee bit smaller than your current overall tire diameter (684mm vs. your current 698mm), and it would offer a significantly softer ride, given the right tire choice.

I had Specialized Crossroad Armadillo tires on my 2013 Cypress. They last a very long time. They are heavier than the Kenda tires but if you want flat protection, they are great.

Continental Speed Ride. One size, 700x42, actually closer to 700x38. Only about $20 each and well worth it. Best compromise I've seen for hybrid bikes on pavement, gravel, dry dirt and grass -- all around riding. Fast and smooth rolling, supple sidewalls, tough and long wearing, reasonable puncture resistance without feeling sluggish. I rode a pair for a couple of years, recently switched to 700x32 Continental Sport Contact II, and am looking for an excuse to switch back to the Speed Rides. They're really good all around tires.

I weigh around 160 (a little less now), and usually rode the Speed Rides at 50-60 psi rear, 40-50 front, and a little lower if I planned on longer rides on gravel, rough pavement like chipseal, or off road. Never a pinch flat.

Question specifics?

Problem is Physics ... you lowered the PSI and got pinch flats , because you lowered the pressure..

add a suspension seat post rather than under inflate your tires..


a much wider tire , like 2" (29er+) has lower operating pressure

Or, maybe you'd like the Expensive Supple casing tires in the $80 each range of Compass Cycles tires







....

Donnelly MSO 40c tires are great and you can safely run tubes down to around 35 PSI.
