What size tire

I have a trek 7200 FX and I would like to explore the possibilites of changing the tire to a slicker tread and a tire with a smaller width. The bike is stock with Matrix 750 rims & Bontrager 700x35. What is the smallest width tire I can put on these rims? I am trying to avoid buying different rims.

measure with calipers, and, voila!

you can go a little fatter that the rim width, but not skinnier

Tyres have a designated size (700x28) but there can be a wide variation in the actual physical width of the tyre.
For most hybrid style rims, 28mm is the narrowest that you should use, and it is a good size for fast general purpose riding.
What type of riding do you do (fitness, commuting/utility, training, all weather?). How rough are the roads.

I use 28mm on my all-round road bike/commuter/utility machine, but avoid the narrower types of this designation which are really 25mm in size.

Look for the sticker on your rims. It might give the actual measurement ... something like 622 x 20. My Fisher Hybrid came with Matrix 550 rims that size. Sheldon Brown (at https://www.sheldonbrown.com/tire-sizing.html) suggests 21 width rims could take a tire as small as 35mm and 19mm rims a tire as small as 28. Maybe a 20 could hold a 32mm tire safely.

In any event you need to figure out your actual rim width to decide which tire you could try.

Good Luck!

You will be limited by the space available around the tire itself - to any frame part. Best to ask your LBS what is the largest they can fit, and then decide from there.

Matrix is Trek's house brand rims. I don't know if Trek still makes them in-house or farms out the manufacture.
