I suspect the OP had good intent to ask a valid question. And if it wasn't, you can't have a monopoly on silly questions here.

The article suggests that this is really only an issue with bigger, low pressure tires, but doesn't explicitly say that.

Do you ride a road bike or mountain bike?

What is your tire pressure upon inflation?



Thank you for any replies.

Think you might want a chi square with size and pressure.

Road. 25mm 100 rear, 95 front.

OD'ing on Vitamin B12 will make up for it. Unfortunately, you can't actually OD on B12.

My main commuter, a 2015 Charge Plug 700x35 tires at 85psi.

My more dedicated roadbike, a 1984 NIshiki International 700x28 at 85psi. When I got the bike in 2009, I was running 700x25 at 100psi but it was too flat-prone and uncomfortable for commuting.

My 1997 Nishiki Blazer Utility/"Mountain Bike". 26x1.85 @ 70psi. After trying all sorts of fat, treaded mountain bike tires, hybrid tires and thinner smoother road tires, I settled on 26x1.85 smoothies. In the winter the bike gets 26x1.65 studded snow tires with deep tread and studs. I run them at 60psi for dry pavement, 35psi for ice, and 25psi for thick loose snow.

My 2007 Dahon Boardwalk 20" folding bike has 20x1.75 road tires at 60psi.

My bike trailer with 20x1.75 tires gets pumped up to 50psi.

I ride a "road" bike (well, a hybrid bike that I converted to drop bars). Tire pressure is 60psi (700x35).

Unless you ride your road bike exclusively on the track and/or are riding tires that are way too narrow for your weight, you really should take some time to get up to speed on the research on tire pressure. Riding at lower pressures will probably reduce rolling resistance for you (due to extreme suspension losses at those pressures) as well as much better traction, a much more comfortable ride, and better tire wear.

I believe the only questions asked by the OP in this thread were:

"Do you ride a road bike or mountain bike? What is your tire pressure upon inflation?"

There was no invitation for you to expound on what you think would work best for me. I'm perfectly comfortable as-is and my tire wear is fine. Thanks.
