Thinking about new tires

My wife and I ride a 2005 Comotion speedster with 700c-32 Continental GP5000 front and 4-seasons rear at about 85 psi. Iíve been pretty happy with this setup, but am always on the lookout for ways I might improve comfort without sacrificing efficiency. Weíre not racers, just a 136 year old couple that likes to ride hilly terrain without having to work any harder than necessary. Iím wondering if we might be even happier going to 38mm tires, such as Rene Herse Barlow Pass or Panaracer Gravel King Slick. I believe 38mm would fit between our seat stays. Anyone with a speedster running 38mm tires on the rear who could confirm that? Also, any opinions on making the move Iím considering in general? We mostly ride asphalt of varying levels of deterioration, plus the rare stretch of gravel. Thanks, Bob

I don't know anything about those specific tires--but it's true that wider tires are generally more comfortable because you can run them with lower air pressure (up to a point) than narrower tires. The tradeoff is some additional rotational weight and possibly higher rolling resistance (depending on the tire and terrain). Since no tire is perfect in all conditions, my wife and I have a couple of different wheelsets so that we can quickly swap tires depending on the terrain.

I'd say give them a try to see if you like them.

I too would love to hear what width others are using. We have a later model Speedster than yours,maybe the last year they had the diagonal center tube. We too would love to know the widest tire for our design. The current model year runs 35c, I've never run anything wider the 32c either at this point.

My wife and I, team age 131, ride a 2005 Speedster. The rear has taken the four 38mm tires I've tried:
Schwalbe Marathon GT,
Schwalbe Almotion V-Guard (tube),
Schwalbe Almotion RaceGuard (tubeless),
Panaracer Gravelking Sk Knobby.
We bought the bike used with fairly skinny tires. Moving to 35mm front and rear (Schwalbe Marathon Supremes) improved the ride and we toured self-contained cross-country from SF to Virginia on those with good results except for some tube failures. I then fit 38mm tires on the rear, but the original front rim-brake fork would take a 35mm max.
I bought a used Speedster disc fork of recent vintage, which has more lateral clearance, and did a bit of monkeying around to get a 38mm to fit. Then I built tubeless wheels front and rear and fit the Almotion tubeless tires. We rode from SF to Florida on that 38mm configuration most of the way (had to switch the rear wheel in Louisiana to a 38mm tube rim for a non-tire issue) and are now back to 38mm Almotion tubeless and are still happy with that.

Sapporoguy, thanks for the detailed and helpful response. And Iím in awe of your cross country tours. It would be fun to link up for a ride sometime.

yep!
Instagram @KarenSteveTandem
for our fall 2022 tour from SF to San Diego to Florida (Southern Tier), we posted 10 pix/videos and a map every day for our 68 riding days.
We had planned to be more ambitious (blog, YouTube) but it was all we could do after a dayís ride just to post on instagram.
For our 2021 tour from SF to Yorktown, Va., we instagrammed retroactively for each day, on the same account.

We're running Specialized Sawtooth 38 mm front and rear. They were initially tubeless - now running tubes. Great all around tire. We run around 55 psi and it's so much nicer than any tire at 100 psi.
