Anyone got some info on bridgestone's new bt015 ?
- Thread starter BentValve
- Start date
does the bt015 come in 195/55 ??
Reports ive read say they are better than the 014s, Pilot Powers and Diablo Corsas.
I met a guy who sets up tire tests and has some 015s that are supposedly 95-97% , I went ahead and bought them.
I dont need them yet but it wont be long.
Neeley called me back up and said that the 015s will NOT replace the 014s however the 014 will be discontinued in 07' and replaced by a street tire based on the BT002 race tires.
The 015s will remain just an OE tire.... also I was wrong on the BT014s..Neeley says they are a dual compound tire according to his info...the website does not point it out.
I am pretty sure we have debated this one here before.
Ive always been thrown off just because youd think they mention this as a selling point, or at least have the DTC logo on the 014 web page.
Anyhow I am sure the BT015 will prove to at least be a slightly
better tire than the 014s.
I would not be surprised if these started showing up on some future Suzuki bikes.
Neeley faxed these over to me..

Ye the new bt002 super street tire is the next big thing from bridgestone. Its to be the newest cutting edge tech,
The 014s will not be manufactured after 07. they will be around of course till stock is depleted.
I still have to say I like the maxis super max tires I have put on. I wish bridgestone would still use the kevlar(like maxis) instead of steel rapped in rubber for the belts. They went cheap.

The Super Sport is..... Neeley is talking about a entirely new tire the BT002 Super STREET.The BT002 is available in a 190/55-17
Not sure exactly what Bridgestone is calling it but at one of my local stores they have a BT002 190/55The Super Sport is..... Neeley is talking about a entirely new tire the BT002 Super STREET.The BT002 is available in a 190/55-17
Yeah youd think theyd designate a new number to the tire Neeley is reffering to.
Oh well, its off a ways, seems at least a year , meanwhile we have tons of great tires to choose from.
Myself, I am sticking with the the BT015s and BT014s ...I might try the Qualifiers as well.
I know a guy with some Dunlop SportmaxGP tires in 190/55 120/70 for $125 a set... 90% tread ...I though about trying them out. I still might.

Not sure what kind of street mileage these tires would get , anyone know?

I have put 2500+ on them before on the RR....bout 7-800 on the track and 2000 or so twisties and highway.
They would not be the BEST choice for fall/winter since they take longer to heat up on the street....if you put a set on in spring and love to hit the twisties HARD, they have more grip than anything but a slick.

The extra "5" difference....190/55 vs. 190/50 is not MM it is the aspect ratio of the tire. A 190/50 means that the height of the tire is equal to 50% of the width....so 190 x .50 is 95mm from the rim to the ground 190 x .55 = 104.5mm a difference of 9.5mm.
190/50 is 95mm tall
190/55 is 104.5mm tall
The 50 series is more " U " shaped and the 55 is more of a " V "
being that the 55 series is taller and has the same width, the contact patch is larger providing more grip when leaned over...also turn in is easier because the 50 has to roll over to the edge vs. the 55 which is more of a drop down to the edge because of it being taller.
I don't have the exact # but the taller 55 series will add 2-3 more MPH to your top end....on the track I don't usually get over 150 or 155. I have had them to 170-175 and there isn't any problems with stability.
The height can also have an effect on your gearing, same as if you had a 42 rear sprocket and went to a 41....not a big deal on the street....on the tracks that I've been to there is always at least 1 turn where your gear selection, entry speed, and engine RPM need to be right so you get the best drive out of the turn. The extra grip by far out weighs any worries of a gear change.
For track days and hittin the twisties the 55 is the BEST way to go....this is why you hear people using 180's instead of 190's....it's a 180/55 vs. a 190/50....the 180/55 has a larger contact patch than the 190/50 and it turns in easier.

Thanks for the info BA..as far as me questioning the stability, I was thinking more about having less contact patch for straight line riding and the lift in the back 10mm is quite a bit!! Id think the lift would make the bike more twitchy and more suceptable to upsetting the front end...or at least encourage the rider to ride improperly after longer rides.
Even with a 50 the Gixxer has pretty agressive seating you really do gotta put some effort into keeping a good form.
I'll probably pick up a set of these just to try out anyways... I wish I lived closer to a track.

They don't seem twitchy at all....at high speeds tires do grow. The 180/55's are standard equipment on a lot of 600's and they handle great and have plenty of top end.
Anything you find in a 190/55 is going to be a GREAT tire....you won't be disappointed. These are Street legal "Race" tires
I've been using 190/55 Pirelli's and Metzler's for 2 years and I love them....for these 2 brands....they are actually the same company, the Pirelli Supercorsa's and Metzler Racetec's....formerly Metzler Rennsports come in different compounds.
In a 120/70 front
Supercorsa's SC1....Super Soft
