I have a bike Friday with Alex rims DA22, etrto 451x14. They currently have primo slicks on them. What would be the most puncture resistant tire for these rims? I don’t care that much about more weight. I hate fixing flats!

I have 406 wheels, but fwi, I'm running the 100psi Swalbe Marathon tyres. These roll well and are very puncture resistant.

The choice of tire in ETRTO451 is very limited, mainly narrow road tires, nothing like a Schwalbe Marathon.

Any tire becomes more puncture resistant with tire liners, like Mr. Tuffy's, Rhinodillos, Slime Liners, etc. Been using them for decades on my bikes. I get to run supple tires and still have protection.

There are 37 tires listed with a BCD of 451 . Widths up to 1.75 inches

Take your pick. or not

Since I started using a Marathon in front and a Big Apple in the rear I've had no flats, for about 15 years now, I think.

Agreed they are nice tires, and an excellent recommendation IMO, but I could not find them in 451 .

I've been using Schwalbe Marathon Plus tires in Chicago for 10+ years without a puncture.

That's the problem: none of these touring tires exists in ETRTO451.

In the list of ETRTO451 tires of Modern Bike, the best option is probably the Panaracer Minits Tough which is the stronger version of the MInits Lite PT (a road race training tire comparable to the discontinued Schwalbe Durano and its successor the new Schwalbe One).

Since we are on the subject of 451 tires. What would be a good choice for daily commuting. Obviously speed is not the most important criteria but rather comfort, puncture resistance and grip under various conditions (ie rain, gravel).

Jipe

Actually, the ETRTO451 size wasn't made for commuting bikes.

In 20", its ETRTO406 with wider tires that was considered for commuting.

I've also heard good things about the Tannus Armour tyre insert

Check if their 20" model fits 451.

For certain types of brakes, there are solutions that extend your brakes to the 406 rim size. You would of course have to get the new rims, too. What brake types does your Bike Friday facilitate?

Jipe

If the bike uses rim brakes, moving from ETRTO451 to ETRTO406 means that the brake pads should be lowered by 22.5mm, that's a lot.

I doubt its possible and anyway increasing the brake arm length bu 22.5mm will have a negative impact on braking power.

If there are road brake calipers, they also limit the tire width to 28mm for most of them.

A solution could be to change the brake calipers for long reach calipers (there are still some models available).

I've been running Schwalbe One HS 462 (28x451) for about a year now, on a mix of gravel and pavement, with no issues.
