....... Mmmmmm ...... Not exactly! Getting a tire to respond faster to steering input is different than the level of grip. Grip is about the tread compound, and speed of response is about sidewall stiffness. Inflation pressure can greatly affect sidewall stiffness, but so can the size and...

I take from this statement, you are still convinced that tires with 44 or 51 psi max pressure have different load curves than tires with 35 psi max. This in spite of being shown several load tables that max out at 35 psi, and not having found any that max out at 44 or 51 psi. And for those who...

Sorry, that's a myth. It's true that more load = larger footprint - and - more pressure = smaller footprint - But they aren't proportional.

First, I hope you realize that most low profile tires have grippy tread compounds compared to high profile tires. Second, low profile tires have larger contact patches than comparable high profile tires. I wish there was readily available data to back that up, but it makes intuitive sense in...

Fixed http://www.barrystiretech.com/rrandfe.html Followup: Maybe not! Second followup: Well, I don't know what is wrong, but the manual way to get there is to type in www.barrystiretech.com and find the link to Rolling Resistance and Fuel Economy and its sister page. Third followup...

Colt X-5, So let's start with this: What changes can be made in the tire arena to make a car handle better? If I leave out an improvement in grip level and focus only on trying to make the car more responsive, the answer boils down to making the car react faster to steering input - and...

Things have been quiet for a few days - so before I leave, I thought I would offer the opportunity to ask questions. For those who haven't been following this thread http://www.mazdas247.com/forum/forumdisplay.php?475-CX-5-Wheels-Tires-Brakes-amp-Suspension: I am a retired tire engineer. I...

Ah ...... Mmmmmmm ....... not exactly. As a tire engineer, I can design a tire that will be sloppy as all get out, and an otherwise identical one that is very very precise - all without affecting the load carrying capacity. It's one of the reasons we do handling tests on propotypes - to see...

yrwei52 , Nicely done. Youve managed to find some things that seem to contradict what I am saying. Remember I said there is lots of sloppiness and imprecision? Well that Toyo chart is one of those. I was hoping you wouldnt catch it, but you did. Well done! But the chart doesnt support...

yrwei52, First, you are going to find - if you haven't already - that the tire industry is chock full of imprecision, sloppiness, and complexity. This discussion deals with some of that. Second, I hope you realize that when you use the term *P-Metric*, you are referring to the load table for...

Hi, Barry of Barry's Tire Tech here. Brillo54 emailed me about this on-going discussion and asked a couple of questions. I thought it might be appropriate to jump in and try to answer not only the questions he asked, but any other questions that might come up - and from reading the thread, I...
