Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Tire width question

I recently put 700x28 tires on my road bike. Victoria Rubino Pro. The front tire is just a hair too wide for my fork. Should I 1) try to shave/sand the sidewall, 2) go back to 25 up front and use 28 in the rear, or just go back to 25’s on both? Possibly try a different brand?
Thanks!!

Under no condition sand or shave the tire. Reinstall a 25. Many bikes are set up for a 25 and 28 anyway.

Use a tire that fits. If a 28 is actually rubbing, even a 25 is flying pretty close to the sun.

Do not try to shave a sidewall. Tire sidewalls are structural and usually extremely thin. Front blowouts are very dangerous.

If the tire is contacting the fork right now, it's going to be even worse under load. Most manufacturers recommend about 4 mm of clearance on each side of the tire, so get out your sanding paper and keep sanding until you have four millimeters of clearance on each side.

The above is a joke. Don't be dumb. Get a smaller tire.

Use the proper size tires, there should be about a minimum of 3-4mm between the tire and the frame. Any less than that and a small stone or stick could jam between the tire and frame, and the results wouldn't be pretty. It's trial and error with tires, for a given size one brand fits fine and another will not.

Only issue on the front? Maybe scrounge or get a new fork. Or retire that bike and get another.

My tires pick up a lot of sticks and throw them back at my son behind me. I'd not want to think they'd jam up my wheel and give my son reason to laugh at his dad.

I‘m a big fan of the 25 front 28 rear setup. This way you won’t have to toss your front 28

You could file the inside of the fork a bit.

(But not in real life!)

I honestly don't know what everyone else here is thinking. Dude, this is a fantastic opportunity to get a new bike, one that will accommodate a wider, more voluminous tire. It's a great way to smooth out the rough riding surfaces.

Upcoming structural failure.

OP could always get a new fork or a bike that's manufactured to allow such tire width.

Look up. See that tiny spec in the sky? That’s the joke.
