What competition tire are you running? and Did you get them shaved?

 

V700. NO.

Kumho V700 - Yes.

It makes a rather large difference in the response/grip of the tire, especially on concrete. And seeing as how the Kumho's generally lose the best part of their grip before the tread is actually all gone (too many heat cycles), it hasn't been an issue for me.

Hoosier's in comparison do not need shaved. BFG g-Force R1's also don't need shaved.

Basically a competition tire will exhibit maximum grip with tread depths 3-4/32's and under. If the tread blocks are taller, then they wiggle and squirm when the car transitions and the car won't handle as well.

 

Advan032R
Nope.

I thought about shaving the tread, but the fact that I do drive them on the street somedays after events made me want to keep them at full tread depth. Plus, as I am becoming more competitive, I am thinking that I may use these for daily drivers and get lighter wheels with Advan048R for autox/track use.

 

Yokohama A032R
Not shaved

I wanted an R compound tire that was moderately streetable and ok in the wet, as I only have one set of lightweight wheels for the car. I will most likely get a set of street wheels next summer, and will put a full on race tire on the OEM rims.

 

Kumho V700, unshaved. If there's a difference, i'm not good enough to tell it on a 40 second run, it was always my understanding that shaving was to keep heat from building up too much on long track sessions...for my money at this point, i'll let the tires shave themselves, and i'll call it "wear". I like my tires unshaved, and my women...

 

I run V700's in the dry and Toyo RA1's in the wet. I do not recommend you shave them if you want an entire season out of them, or as many events as possible. If you have one or two big events you’re going to use them for shaving is recommended if you have the dollars to spend.

 

Kumho V700s. Unshaved (I would reserve the shaved option for track use, not autocross use). Highway heat cycled.

 

i ran v700, but have switched to hoosier a3so3. i probably would have kept the kumhos's (cheaper tire, and i can use them on the track & autocross) but they didn't have a 225/45-15 and i ran staggered sizes (205/50 in the rear)
