Tire width recommendations

Road Cycling ďIt 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.Ē -- Ernest Hemingway

Tire width recommendations

This is my wheels width itís a 700c wheel. What width tire would you recommend me use 23 25 or 28c



it is a clincher style
I would like to run a 23c in the front and 25c in the rear
or
25c in the front and 28c in the rear.
what do yíall think I can get away with. With the width of these wheels.
thanks in advance

Tire recommendations are usually based on the "inside width".
The photo shows:
3/4 inch outside width = 19mm
15/32 inside width (approximately) = 12mm.

Is that a classic bike? somewhat newer rims are 15-22mm internal width.

What size tires were are on it previously?
Older frames were designed for quite skinny tires. How much clearance is there at the brakes, under the fork crown, and on the sides of the tires, both at the fork and at the rear stays? (I measure by fitting a hex "L" wrench into the gap -- a 5mm wrench is 5mm across the flats, for instance.)

im using these wheels on my beach cruiser so there is plenty of clearance. I didnít have any clearance issues previously with the 23c solid tires that I had on them. They just rolled like a hacky sack. Thatís why Iím going to pneumatic tires now.

I would like to run 25 & 28c
but my lack of knowledge is creating this assumption that 28c is too wide for this wheel. So thatís a big reason why I made this thread.

28mm tires will be fine on those rims. Don't sweat it.

I would not run a smaller tire on the front

I believe this could result in a negative in the handling department... reduce the amount of trail (?)

can't recall though ... not sure

what do you mean by ďtrailĒ

im doing it purely for looks but recently this idea of mine has been backed my a video I watched by a veteran cyclist named veloharmony. He mentions how a few of his bikes have a raked setup.

It's fine to use a slightly smaller tire on the front. Conti actually sold a pair of 22/24mm tires at one point. If you don't what you're talking about don't post.

I'd put on it anything I wanted that will also fit in the frame. If I got the widest possible tire and later found out it handled funny on curves and such then I'd get something else, probably a little narrower.

The wider the tire you put on that skinny rim, the more likely I'd expect to feel a little sideways rolling of the tire when going around curves or maneuvering. But I wouldn't get too concerned with even that if you don't ride like you are in a BMX race.

I am a little surprised that you have a wheel rim that narrow on something you are calling a beach cruiser. Or is it just a cruiser from vintage days.

Running a smaller rim up front?

cxwrench: "but to put a smaller front wheel on a bike that was designed to have the same size wheels front and rear is just stupid"

if the change is for looks - fine

but be aware smaller front tire can lead to change in head tube angle / amount of trail - and this could result in 'quicker steering' - less stability at speed - not a good thing on a skinny tired road bike

it's a small amount but still worth mention

I got 6 tires today for $10



4 23c tires
2 25c tires
so that settles it

I got 4 23c tires for the front and 2 25c tires for my rear.

An Electra super deluxe from the early 2000s

Iíll be swapping the rear hub to a coaster brake hub soon. 70mm deep FYI

The OP is talking about fitting a slightly narrower front tyre, not a smaller diameter front wheel. What you are saying above is totally irrelevant.

My math skills aren't the best, but isn't a 23mm circle smaller than a 25mm circle?

(Cross section of tire if that was too obtuse)

Those are tyre width dimensions.

Someone will be along shortly to calculate the change in trail per psi to further frighten us into thinking bike tyres are more complex than quantum physics.

Not a significant amount for one or two size differences. I run 25mm front and 28mm rear. OEM was 32mm.

He means a smaller front tire will effectively reduce the front wheel radi. Drop the front and make the steering head a touch steeper. This plane rotates toward the rear and reduced the distance from where it intersects the ground and the vertical plane through the axle. This is the trail. Very small for a few tire size differences.

Thank you to everyone that helped
hereís how it turned out. It is my first fixed gear setup. I donít really like these handle bars. Feels like Iím reaching. maybe Iíll put back the bc bars or see how far forwards I can go on my seat position. Itís a 16x46 I got that chainring and arm today for $5. The crank set I bought for $5 and my previous were both 170mm so I only changed the drive side. With the pedal.
Im having trouble in the rear where directly north of the presto valve stem the tube is pushing the bead out at around 60psi. So Iím rocking 50psi and keeping an eye on it. Hopefully it settles and I can creep up in psi. The front is good so far but im only using 70 psi to help let bead settle. These tires suck to put on Iím definitely getting some better tires come Black Friday.

Sure it is, but that is only going to make a 4 mm difference in the tire diameter. So do you really feel that a diameter difference between 668mm and 672mm is going to affect trail and such by any real noticeable amount?

And the actual effect is only half that since the wheel is held at the center. So only 2 mm height difference on that front end.

I'm not claiming it would make a difference (it might on one of my bikes with a 75 degree head angle). Just saying that it's not "totally irrelevant".

Yeah well I'm saying it IS totally irrelevant in this context i.e. the difference in steering geometry between a 23C and 25C tyre is totally insignificant. Fitting a smaller wheel e.g. going from 700C to 650B is what would make a real difference to the geometry and that's where the other poster (t2P) was getting confused.

Maybe 1 millimeter difference in trail from a 23mm tire to a 28mm tire.

I'm not confused

I had a friend that was a custom frame builder - millimeters matter
