Hello,

I have a 22mm Veloflex Master clincher and a 23mm version of the same tire.

Which combination should I better install on a steel road frame with aluminum low profile rims, aimed for easy long rides? 22F/23R or 23F/22R ?

Thanks...

Think about how your weight is distributed on the bike and where the most rolling resistance is located - front or back - and everything will be illuminated.

Answer:
22F/23R

Bicycle weight distribution is generally 45/55, Front to Rear, under general steady state rider/riding conditions.
22 goes on front, 23 on rear.

btw, if you weight under 70kg's, you could ride 20mm tyres. And if your over 100kg, you probably need to ride 25mm tyres.
Anything in between needs a 22/23mm tyre, which is fine for most potholed roads.

But, tyre inflation probably matters more than tyre width in most situations
Just pump em up to max inflation once a week (if butyl tubes), or every day or so (if latex tubes), and you should be right.

You are better basing tyre width on what type of road surfaces you ride. After more than 30 years of riding bikes, including competitively, I would not notice the difference between 22 and 23, just like I do not notice the difference between 23 and 25.

Cyclists also 'adjust' comfort by altering the amount of air in their tyres, if you haven't noticed.

I'm about 75kgs and have used 19/19 with no issues. Tubular tires though -- not sure if that makes a diference.

Hi,



Max inflation being the maximum the manufacturer allows or?



19mm, really ?? Does that not expose the sides of the rim? How about rolling resistance?
Or maybe you use the 19mm tyres just on the track....

Remember also that tyre width matters with repect to rim width (as measured at the rim bed). For best aero behaviour it is best practice to mount a tyre on the frontwheel that is equal to or 1mm wider than the rim bed's width.
Since a bike is moved forward by the rear wheel a wider tyre offers better traction (not necessarily better rolling resistance as is often wrongly promotely lately).

Ciao,
