Bought a 2016 Haro Annex Expert for my son. It came with 28h Alloy double wall DA16 rims (don't know brand of rims). The tires are Kenda "Kompact" K1054 20x1 3/8". Can I put 20x1.75' or 20x1.95' tires on it? Thanks in advance.

Yes, you can.

The 20 in 20" x 1.75" refers to the rim/tire diameter. The 1.75 in 20" x 1.75" is the tires width. In other words, anything with a 20 in front means it'll fit any 20" rim.

For an added example, a 24" x 2.25" means that a tire fits 24" rims and it's width is 2.25" wide.

The width is how wide, or how "fat" a tire looks. There are advantages and disadvantages when it comes to running either a skinny or fat tire.

With a skinny tire, anything below the 20" x 2.10" range, in my opinion, will be fast with little rolling resistance, but landings may be a bit rougher since there isn't as much cusion as a fatter tire.

On the other hand, a fatter tire, maybe around 20 x 2.30" or even 20 x 2.50" will be very good for softer landings, but may slow you down with all that rolling resistance.

Would they fit on the rim? Sure, probably. Are they suitable for that rim, and, indeed, the bike itself? I don't know. That's a race bike you got there. If those rims are Alex DA16 rims (seems likely?), then they're considerably thinner than what the community here rides. I don't know at what point a tire becomes "too wide" for a given rim, so I can't help there, but also be mindful of the frame and fork and will the larger tires rub on on even one of those areas.

I'm not so sure the rim might be too small to accommodate a 1.95 tire. It might but I'd suck with a better set of 20x 1 3/8' tires

Tryed this in the 80's..
Answer is: it will fit the rim Intel you ride.
20x1.75 tire works for a while,then the tire will peel off the rim. The depth and with of the rim is to small (shallow). Which causes the beed to slip off. 20x1 3/8 are a race rim. Has some flex to them and easy to bend
Best advise
If you want to have a wider tire look for a 20x1.75 wheel set

Not trying to downgrade that bike , but swap tires as soon as possible . Rode them a couple years back and every 360 even when landed clean , the bead would fly off the rim and it was constantly on both sides . Horrible tires

20x1.3/8ths isn't the same as 20, a "normal" bmx tyre probably won't fit (the same way 700c, 27x1.1/4, 28x1.3/8ths are all different. A new road tyre won't fit an old rim from the 70's/early 80's). Tioga make the powerblock in 20x1.3/8ths though, have a look at that
