Well this is my first bike and these Bridgestones really aren't building any confidence with steep lean angles. So after some research I have narrowed it down to two choices: Pirelli Diablo Corsa III, and Metzler Sportec M3 Supersport. The Pirelli's arent made in a 65 series front so I would have to go 70 series in the front. Metzler makes a 65 and 70 front. I was just wondering how would it affect handling to go with a 70 series? Has anyone on here done it? I'm assuming so since so few tires come in 65 series. Also if anyone has either of these tires some feedback about performance and durability would be awsome. Last question, if I were to go with the Metzlers should I go with the 65 or that 70? Any other recommendations are very welcome, I do a lot of commutingon the highway(100ish miles a day when its nice out) and I flog the hell outof it in the twisties on the weekend, thetrack is on the list for nextspring. Thanks in advance. Sorry about therambling.

P.S. I was just looking at them and I found the Metzler in an "All New" 190mm wide by 50 aspect ratio. So thats 10mm wider and 4mm shorter. Waste of time and money for a cornering bike...?

 

You can run either one. Just remember to readjust your suspension and geometry if you go up one size. I do not have the numbers memorized, but if you go up to the 70, either raise the tubes in the trees and/or shim the rear up some.(normally 5-10mm's). Even if you stay with a 65 profile, recheck your sags and adjust accordingly.

 

The 190 will slow the handling on the 636 too much but the 70 series front will be good for it because the 03-04 636's are twitchy anyway. How extreme are you lean angles that you don't like the stocker? I have the BT014's on mine and I love them even on trackdays and they will last longer.

 

I just put new tires on my 06 636. I went with the dunlop qualifers. The front is a 70 series. I highly recommend you get a 70 if you are into cornering. The bikes rides exactly the same, but you have more leas capability due to the slightly larger sidewall. Ididnt change my suspenion at all. Ive read that the metzeler m3 use a still compound, and make the bike a little more bumpy, but i have never used them.

 

Another tire thread!!! I love these!!! Tire opinions are awesome.

If you're into cornering one tire is better than another? (sorry Eddie) NO, At the AMA/motoGP level, sure, but not at our level and we can't get those tires anyway.. The only tire that has a different "footprint" at lean angles is the Michelin PRC which has a "pointier" profile causing a bigger contact patch at full lean. The rest of the tires are neither here nor there for normal everyday lean angles.(as long as it's quality tire NO CHIN SINS(sp) HERE BUDDY). Why? Because a tire is a tire is a tire. Why do I use PR's and slicks, because now we're talking heat cycles and the feedback you need from your tire when sliding or the feedback you get from your suspension. (suspension is EVERYTHING, start another thread for this one) because if your suspension is not set up your tire type really don't matter (hell, nothing matters LOL).

Rideit, bottom line is this. Which tire are you most comfortable with? How much do you have to spend on tires? Do you want miles out of your tires or are you trying to lose chicken strips to impress people? Stick to the correct size tires, going from a 180 to 190 ain't gonna do nothing fer ya. Suspension is where you need to spend your hard earned money if you like the "twisties". Suspension is everything. Did I mention that?

For street riding, and using Deals Gap as the most extreme street riding, the 208's, 014's and other brands high performance STREET tire, is way more tire than you'll use. (coughcoughnometzlerscoughcough)

My .02. (ok more like a $1.20)......... **** off.

 

PS setting static sag is just the beggining.

 

Y is absolutley right, suspension is everything. I couldn't believe the difference when I got it set up correctly (for me) the first time. It was like a new bike! But I disagree on the tire opinion (don't we all disagree on these tirethreads anyway?) After the suspension was changed, I got some qualifiers and they outperformed the dunlop street tires I had before by a longshot. And yeah...stick to the correct size, if you want to run 190's get a bigger bike. Thats my $.02

 

HOW did they out perform??...WHAT were the differences in one tire from the other?

 

The grip level is much better on the qualifiers. Don't get mad...thats justmy experience with the tires.

 

Also, I am not comparing them to your beloved metzelers or PPs, my only experience is if you want dunlops...get the qualifiers.
