Is that Bridgestone a BT45 you are talking about with the bubbles in the other thread? If so that is a bad mix with a ContiForce radial front and BT45 bias rear and not really a safe setup. If that is a good tire on the front and you still want to use it you need a radial rear to go with it. Maybe a 150/60 ContiForce rear, or put a bias set on both front and rear.

 

No i know. I am looking to replace that bull **** defected tire and i have a second front rim just sitting around with a Contiforce already mounted so i figured i would just get a radial back. Thanks!!

 

with a radial front, you should use anything that will fit in a radial for the rear. do not use a bias ply.

you can have a bias front, and a radial or bias rear, but if the front is a radial, you can only use another radial in the rear.

you're probably looking at something in the 150/60R17 range.

 

Ok! yeah he was saying that because currently i have a bias back and front, but i have another rim with radial on it for the front, and i am thinking about using it and getting a radial rear as well. Thanks for the size help!!

 

You gonna be making a new post after discovering your brand new 160/60R17 tire won't fit because it keeps hitting the front of the swingarm?

 

No i am gonna talk to my local shop first, i just wanted to see what you guys would use

 

Well, if you can find maybe a 140 or 150 rear radial, give it a shot, but even a 150 can potentially have fitment problems that would only be solved by adding a link to your chain.

 

Thanks Pogo!

 

Hey Pogo dont wanna make a new thread, but i am also going to need to replace my front tire. I currently have a Avon azaro av46-st in the rear (radial). Now i see you say it's ok to run a bias or radial front with a radial rear, but what would be the difference in doing so? Would you prefer to stick with same tire construction for both front and rear? Thanks!

 

slip angles.

I can't really answer that, because I would never buy a radial rear tire. This bike's suspension is sloppy as is and is designed for bias tires, which are stiffer than radials.

And as to why... well, it's an extremely complicated physics system that I'm not going to pretend to fully understand, because even the experts have yet to design a computer model that 100% accurately simulates the forces going on in a motorcycle.

If your rear has anything close to 10k miles, I would replace both with stock sized bias tires.

If you want to keep that rear, get a bias front and deal with it for a couple thousand miles so that you can eventually run both bias tires.
