Poor Grip in the Wet - Bridgestone Potenza

[Vit4wd]

Those who thought only the Yokohama Aspec has poor grip in the wet will be surprised that the Bridgestone Potenza is no better, esp in those multistorey carpark wet cement slopes when it rains.

 

Drove a friend's car today and experienced it first hand for myself.

 

The front wheels practically spun when going up a multistorey car park!

 

This Potenza is noisier than the Aspec DB but grip is excellent for dry runs at high speed.

Think you are right, I have the same experience. I am not sure why as the tyres are fine on wet roads, the spin only happens inside the basement/ multi-storey car park.

[Vit4wd]

When I was previously using the Aspec A300, I never encountered the tyre losing grip, slipping or spinning on wet cement floor of those multi storey car parks.

 

The Potenza performs worse in this aspect.

[Ncp91]

It means that the tires have a decent tread pattern that clears standing water well, but the tire compound itself isn't soft enough to afford decent adhesion on smooth surfaces.

[Vit4wd]

Can anyone analyse the thread patterns or compare the compounds of the Bridgestone Potenza & Yokohama Aspec A300 and tell us why the Bridgestone Potenza is poorer in wet grip.

 

Practically everyone says the Yokohama Aspec A300's wet grip is real bad, but when I was using this tyre, honestly, it was not as bad as what I have heard about it.

That is a SO3 right ?

 

On smooth surface like smooth cements and a little wet...I think most tyres would have their gripping ability reduced.

 

On normal road surface, I have no problem with the SO3...but when you drive on smooth surface, like the metal plates on some roads, do watch out as grip is compromised.

Ya G'rider is rite. Cement and metal surfaces are definitely much more slippery than asphat surface. Plus a little bit of oil (normally found in all car parks), even the best tyre would not perform under such adverse condition. ONLY commonsense prevails! Cheers!

Honestly, I have never experienced slippage on wet MSCP cement floorings, except in the Bridgestone Turanza.

 

I have used Michelin MXV3A, Yokohama Geolander, Bridgestone Dueler, Yokohama Aspec A300 and a fair bit of other low end Jap brand models.

Bro i tink all cement surfaces on MSCPs are slippery esp on a rainy days, after many cars entered the carpark with trails of water left behind.

 

Drive as per normal shld be ok. For the ramps, make sure pick up enough speed or engage a correct gear before going up.

[Seanboi]

Tink it's a G3

[Furrynadz]

more land area = poorer water evecuation at high speed but better for low speed cos more contact area

I believed that's a GIII.

[Stivo]

GIII has poorer road grip on wet but OK on the dry....

ic. and i heard it's noisy.

The only thing I could think of about the poor performance is :

 

1) Tyre was new

2) Tyre pressure was not balanced (ie. one of the front tyres' pressure was higher than the other)

or

3) You've went over a patch of engine oil.

Cheers!

I've mentioned this before. G3's arent that fantastic for wet grip. Above average but not class leading in V rating. In H rating are appaling for wet grip.

 

I forgot to mention, i have used the a300's and they are a pretty damn good tyre (relateive to the grip in its class). in the wet they would be rougly abt the same as a v rated G3, but they can't hold a candle to it in the dry.

I've used Michelin MXV3A, Perilli P6000, Bridgetsone GIII, Goodyear GSD3-F1 and now with Continental Sports Contact 2; in my appartment basement carpark, I need to make a U-turn after the ramp down, during heavy rain when the floor is wet, all the tires above slipped if you go fast.

 

I beleive on wet and smooth surface, all different brand of tires will slip; probably it is a matter of how bad it slips! As far as I recall, the F1 is the worst on smooth surface.

[Vit4wd]

Yes you are right! The Bridgestone Potemza is exceptionally noisy.

 

Can't imagine this tyre on a Lexus.
