EZ Sport tire size

I'm wondering if anyone has put more narrow tires front and rear on their EZ Sport. How narrow can I go and stay safe? My weight is 160.

Look on the sidewall of the tires to be sure what size tire you need. It has 26" X 1.5" rear ISO 559 and 20" X 1.5" front which would be ISO 406. You certainly can go with narrower tires within reason. If you go to the Sheldon Brown website and look up rim sizes, you will find a chart showing which tires work on your rim. It is based upon the width of the rim. I went the other way on my trike, using 406 X 1.4" front tires in place of the paper thin Schwalbe Ultremo ZX 23-406 tires that come on it so I would guess you can use the Primo Comet 20 X 1.35 https://www.niagaracycle.com/categor...ack-black-tire. I have this tire on my Haluzak Horizon SWB. It's a bit more expensive than the Tioga Powerblock S-Spec 1.4" that I use and really love on my Catrike 700. You might have to replace the tubes as well. My favorite place for tires and tubes is Niagara Cycle.

I'm pretty sure you could mount a Primo Comet 20x1.35 on the front and Primo Racer 26x1.25 on the rear. I don't think I'd want to go any skinnier than that, though. Primo is a relatively inexpensive racing tire that'll give a nice ride, last about 3000 miles; but doesn't work well in rain and cuts fairly easily if you ride in junk.

At 160 pounds, you can get by with thinner tires than much of the population.

Weight won't be an issue. I seem to remember that they have fairly wide rims.

I run 26x1.25 in the rear (78-80 psi) and 20x1.25 in the front (68psi). Both are folding bead tires and at those pressures, they soak up the road buzz in the handlebars that was driving my hands crazy. bk
