Worthless V100 tire thread

[john zibell]

The manufacture's recommended pressures are stated to give a balance between traction and longevity. If you are running on the track, you want the core temp of the tire to reach about 100C. That will give max traction for the compound of the tire. To achieve that temperature lower the tire pressure a little so the tire flexes more to generate heat. However, the tires won't last long under those conditions.

Precisely John. Wonderfully stated.

My point that seems to be somehow eluding some, is that Moto Guzzi doesn’t intentionally lie to you.

They tell you what pressures to run based upon their knowledge and understanding of what they engineered and built.

That is idiocy incarnate.

Given your “ bizarre logic” here of “want the bike to handle better”…

Are you actually trying to state with a straight face, that the manufacturer, who designed, built, and throughly tested your Moto Guzzi motorcycle, intentionally tells you to run a tire pressure that produces worse handling than is actually possible?

You are ridiculously stating that if one simply disregards Moto Guzzi, and listens to you, and lowers the pressures, the motorcycle will “handle better”.



Uh huh…

I run 41 psi cold rear and 36 psi cold front regardless of if I'm riding solo or 2 up.

I have to laugh ️️
I set tyre pressures at manufacturers ref, have done all my biking life
What happens if you’re a fatty compared to a skinny ….

I was specifically referring to the V100S which specifies one tire pressure for the front and rear tires regardless of the load on the motorcycle.
I’ve owned other motorcycles that did recommend different tire inflation pressures according to the various load possibilities.

All these posts on tire life and not one mention of what pressures you are running!
Makes me wonder........

How much trouble it could cause?

The above quote is 'click bait' and I am kicking myself for not jumping on it sooner.

Tyres are part of the suspension as in everything suspended from the vehicle is in concert with everything else.
So generalisation is used and a range of answers could be equally valid.

Remember when radial ply came out and virtually superceded cross-ply?
Cross-ply ply was 'generally' stiffer in the side walls and could tolerate lower pressured whereas radial ply was more compliant and acted more as a suspension component.

I personally use Pirelli GT2 spec A on the rear which has a cross-ply component in the side walls and can tolerate a greater loading for the same pressure, but I am guessing that when loaded for use the pressure goes up also.

So a general recommendation for a pressure start point is followed.

We all have a start point, don't we?

It is common knowledge that most manufacturers post their RECOMMENDED tire pressures to provide maximum tire life and safety, with good handling.
It is also common knowledge that lowering tire pressures from those numbers (within reason) provides increased traction, but at the expense of tire life.
It all depends on what your priorities are in the type of riding you prefer, as neither is wrong.

I’ve ridden and raced over 40 years. I fully understand this.

You missed the point like I wrote in #42.

It’s all good.

To specifically answer this question -
Solo - generally around 36F/38R, but the type of riding can require some change to those numbers
Two up - generally around 38F/40R

My Pirelli Angel GT2 rear tyre has the A marked on it, denoting the version for heavy bikes. Did everyone's V100 come with this version or do some of you have the standard tyre? I'm wondering if the stiffer sidewall on the A version adds to the harsh feel of the rear suspension and am considering getting the standard tyre (or a different brand) as a replacement. I'd also prefer a 180 width instead of the 190, but that's another question.

Yep my V100s has the "A" marking on front and rear tyres

I also have the A designation on mine.
I've heard that it doesn't make any difference regarding ride quality, and tread life, but I could be wrong.
Most of my riding is 2-up so, I'm okay with the A's.

 

[moparnut72]

Mine are "A"s also.
kk

 

[dsw]

Mine has the "A" markings on both tires too. Interestingly, when I go to the Pirelli motorcycle website, it seems to recommend standard Angel GT2 tires vs the "A" (unless I am mis-reading it)

Yes I noticed that. The Pirelli website also recommends Diablo Rosso IV for the V100. I doubt they are heavy duty tyres.

Not sure if you are looking at a radial but Heavy Duty tires will be bias ply, not radials.

Pretty sure @Seasider is referring to the GT tires such as the Pirelli Angel GT(A) and Michelin Road 6 GT as heavy duty tires.

Everything I know shows them to be radial tires, but with an additional ply or plies.

 

[scottmastrocinque]

Understood.

Having owned my own workshop for many years, I know that they are playing a marketing game by calling it heavy duty for GT motorcycles.

A true HD tire has always been a multi-ply bias tire with extensive sidewall rigidity for heavyweight touring cruisers, i.e Harley Davidson FL’s and other comparable giant cruisers.

Guys, by subject heading... this is why Tire and Oil threads always crash and burn. This thread may be soon locked.

It has been rumored that the Angel GT II has been discontinued.
