Question

Long-winded post:

I got a friend who gets slightly used race tires and sells them to everyone around here. He can get me a couple of D207GP's for $180 mounted balanced and all and he claims that they only have 1 heat cycle and about 40-50 miles on them.

When I start looking around at what a new set of street tires and mounting costs it very much seems like this deal is worth a try.

I have heard a few different viewpoints on this subject. Race tires don't last anytime on the street, You never get them up to proper operating temperatures, They are only good for a few heat cycles and then they're junk, They're not made for the street.

Then there's the other side of the story: You can power wheelie in the rain, Street compound tires are scary...blah blah blah

I have gathered that everyone around town that has race tires on thier bikes absolutely love them but I wanna hear it from other people besides the local squids.

I would say stay away from them. They are totally diff than street tires and I seriously doubt they are better in the rain. No grooves to displace the water! There was an article a couple of months ago in Sport Rider. They pointed out the huge diffs and why you should stick with street tires.

I don't think it's a good idea unless you get the tires dirt cheap. 180 is not cheap for used take offs. New D207's cost 190 a set, last longer. Don't believe the heat cycle/operating temp hype. There's some thread around that distinguishes these notions. If you want the tires for added traction....well maybe it's time for the track.

These guys are right. Stay away from the race tires for the street. You'll never come close to keeping them at the temperature in which they were designed to work the best.

Instead of spending the dough on track tires for your streetbike, why not spend the dough putting your streetbike on the track for a class? You'll get a nice taste of racing, without having the wrong tires on your bike! Just a thought...

You will not do any better on the street with race tires. They will wear out quickly. They cannot handle the multiple heat cycles. You will never see the benefit on the street because it is just impossible to keep them at the temprature needed to see the benefits of the race compound. I see deals all of the time where I can get race take-offs for less than $100/set. For $180 I would spend the money on a tire that will last and give you plenty enough grip. I run street compound 207's for track days and while I would prefer to use the race compound the streets work quite well. The bottom line is street tires are made for the street and race tires are made for the track.

I can get a set of take off's for $60 plus $12.50 a tire to mount & balance. $180 is WAY to high.

I am going to try a set of take off's and see if I like them better (on my bike). I have tried a bike with them and I liked the way it felt. But it wasn't my bike so I did want to push it too much.

You will here alot of stuff about race tires.
I think the only way I will get the truth is to try them for myself (also read as much info I can get my hands on).

The info. I have read is they do work really well. And alot of the guys were I ride will never go back.

I will let you all know how I like them..

where are you getting new 207's for 190?

Chaparral has them for 230 for a new set roughly but then I have my local shops who will just love to mount them for me at 50 bucks a pop.

I now want to steer away from the race's and try a set of MEZ-3's. I have heard too much bad stuff about the 207 streets.

Another thing to consider is that the race compounds are TERRIBLE in the wet because they don't have any silica in them. Something to consider if you ever ride in those conditions. I remember a Michelin Rep. talking about the differences between the street and race compound tires in a Sport Rider test. Silica and the resulting wet grip was on of them but he also talked about longevity. He said that the race tires were designed to go through one or two full heat cycles before performance signifigantly dropped off. Now, a race compound tire that is used only on the street may never hit full temperature, therefore lasting longer...but why bother at that price? Like the man said, if you need that much extra grip on the street, you shouldn't be on the street. I'm more worried about the race take-offs that everyone buys for cheap. Those have been through AT LEAST one full heat cycle on the track. You're definitely not getting the same tire they started with. Given the variables with purchasing take-offs and the fact that I have been unintentionally caught in the rain before, I would rather buy new street compound tires.
