Default Bridgestone BT-002 tires - NEED OPINIONS

I bought these tires (Type 4, ultra soft), last fall and used them for one track day. They were really awesome. I hope to get at least 1-2 more track days out of them, there's plenty of tread.

My question is, is their life highly dependant on heat cycles like "real" race tires? They are described as "DOT Supersport Race", so are they more like street tires (tollerant to hundreds of heat cycles) or like race tires (good for only 10-15 heat cycles)?

Another question: Would anyone recommend (or not) using a Type 3 (soft) on the rear with a Type 4 (Ultra-soft) on the front? I've heard mixed opinions about this before.

Thanks!

So much of this is up to rider experience and knowledge as well as bike set-up. Many people are ignorent to the fact that different model tires (even within a manufacturer) often times have different profiles. Supersport DOT tires are 'LABELED' that way in order to get them able to be used for racing, but in reality they are pretty much a grooved slick race tire. Many people who try several different tire brands or models within a brand make decisions about those tires that are often times inaccurate. Tire profile is part of the witchcraft known as bike set-up, not having a bike set to each tires profile will give you false information as to how those tires work in reality. Places like GMD Computrac can accurately set-up a bike for each tires profile so as to get a more accurate representation of their capability, but this is done by very few riders and racers so lots of bad info ends up floating around out there. A tire that works well for you may have more to do with the current set-up of your bikes chassis than the tire itself, a tire that doesn't work could be a victim of that as well.

Just thought this info might be useful.

Type 3 is medium, Type 4 is soft. I run the mediums, f/r.

With warmers, I've pushed them to 3 days in the Expert class. Could possibly go for more but didn't want to push it. Most of the time, I'll sell them after 2 days.

I wouldn't ever run DOT race tires on the street but some people do.

Imo, excellent tires.
