I rode on the Pirelli GT Urban tires today

[ReapThaWhirlwind]

I can now say they are incredible urban tires.

They roll very smoothly and handle the urban environments with ease. Every crooked sidewalk, ridge, drop, pothole, construction rock gardens; the works. I have the 27.5 x 2.25 tires and they basically turned my rigid bike into suspension with the way they absorb the shock. I think these tires could handle even the mean streets of LA with ease. That's an incredible merit. These are marketed for any bike, but I think they would truly shine on eBike setting. They're a pretty wide tire, so they're a little harder to push than average. But the width of the tires gives you a lot of grip on the road, balance, and comfort to swerve. Strongly recommend these for anyone looking to improve their eBike setup.

If anyone has any questions, feel free to ask.

I've seen that Pirelli also has these in 700c at about 38c width, making them a great commuter/gravel choice tire.

Please realize I am trying to find value in your post other than just flowery words that could describe any tire without having further information. E.g. you can certainly reduce air pressure on most tires (depends on min/max specs) and experience a more cushioned ride; and regardless of a suspension or a rigid frame, the geometry, materials, and other components also affect a bike's "cushiony" feel so only giving a tire credit there is nothing provided for a reference of comparison.

What do they cost each?

What type of tire is it? Clincher, tub, tubeless, "solid"?

What inner rim width was the tire mounted?

What pressure did you run at? What pressure(s) are factory spec'd.

Were they compared with another tire of the same design (clincher, tub, or tubeless) and size at the same pressure using the same inner tubes (if applicable) you tested the Pirellis with, and tested on the same rims and bike while riding the same course you rode the Pirellis on?

How many tires (brands and models) did you compare the Pirellis too?

Were they tested in the same weather (primarily temperature due to tire pressure changes; but also wet conditions to compare against your other tire(s))?

Was the "running" pressure checked mid ride? Pressure is greatly affected if tires are inflated in a cooler or warmer temperature than at the ambient riding temperature (ex. pumping up tires in a warm house and then riding in cold weather which of course reduces the tire pressures compared to pumping up in the cold air).

Do you use a calibrated pressure gauge? If not, then disregard pressure questions since you technically do not know how much pressure you inflate to, nor if readings are consistent.

When doing your comparison testing did you ensure that the gross weight (you, bike, accessories, etc.) was the same?

It you did not meet all of the above criteria then your comparison means nothing. To do it properly the only variable would be the tire; but I assume that you probably missed at least 2 items (only takes one extra variable to make any testing rubbish) making your review near meaningless. All we know is that YOU put new tires on a bike and YOU like them, but without any qualifying or clarifying info for others to make an educated decision.

Let's face it, when someone gets something new there is often a psychological boost (placebo effect) be a positive outcome so you subconciously psyche yourself up regardless if there is any measurable difference or not.

If you want to do true product testing and reviewing, AND pass it onto the unsuspecting public than it is encumbent upon you to divulge how you tested and compared the product. I would have been fired if I wrote up a product report (I previously worked as a industrial quality control engineer) and handed it to a design engineer in the manner in which you presented your "review".

I will wait for yor accurate comparison under more controlled conditions.

I know you wanted to show your bike with new tires, but a detailed photo of the tread and sidewall would have been more appropriate since that is the focus of your post.

I do appreciate you presenting specific products for our public consumption, but you need to make it much more informative if I am going to spend money based on your "review".

If you have ever done a comprehensive review and comparison of a product or method, you realize the amount of time and effort required to provide accurate and unbiased data. I have done many tests which needed to be performed again when discovering an unexpected variable which skewed my results. I assume you did your comparison while ignoring known variables and thus it has no bearing on my decision to purchase or use the product referenced.

See you all in 3 to 5 months after I punch out another 2-3 thousand miles. Not working and avoiding all social media and news is fun and certainly much more realistic. Here's to looking at the world and not an electronic device! Cheers!

I can't relate to a lot of this honestly. Reducing PSI doesn't provide (at least for me) a more cushioned ride so much as it does produces a more laggy ride with the addeded rolling resistance from lower psi drag tearing away at your soul.

They are about $35 to $50 each, before tax and shipping. I see them floating at around $25 each right now. I paid about $75 for my set.

This is a clincher tire.

I am running Sun Ringle Inferno 27, which is about 2.2 (22mm).

I am running at 65PSI―which is the max rated PSI.

Yes, I have a PSI gauge on my air pump. They were inflated and rode at similar temperatures.

Before this I rode on the Continental Contact Speed 27.5x2.0. Also great tires. Very fast for fat tires. Great acceleration. I actually overclocked these tires at 70PSI. They eat up bumps very well, but not quite as well, and their handling is not quite as well either. Wet grip was kinda poor, although the last pair I had seemed to have improve some. It still wasn't enough for what I need. And that's why I decided to switch up. There is a noticeable difference between the two tires, that it's definitely to say, we can't just describe any tire by all the entire same qualities.

You're overthinking my post.

We are talking about the empirical evidence of experience. This is a testament of my experience, having rode many tires of many different and similar widths. The objective wants to be to discredit the empirical evidence of experience by mere doubts and perceptive fallacy, force projection, to create sleight of perception.

Let's not do this. It's not sophisticated.

I even put if you have any more specific questions to ask them. That's all you needed to do, and spare the pessimism.

These are big muscle man tires. They're really for easy cruising, or hardcore eBike control based on my experience.

That's maybe the most important detail I could add from here.
