I'm tracking my TT more and more. I am thinking about getting track tires. I believe R-compound is the next step. I'm using the OEM wheels at the track. Who makes a good track only tire - I don't think I'll be running on wet tracks - what should I get?

 

pilot sport cups

 

Track only, the Hoosiers are very nice.

 

My experience has been limited to the following:

Hoosier RS303's are fantastic but wear very fast and are very expensive.

Yokohama AO32R's are used by most folks as R compound wet tires, but work well in the dry. I know a few 911 guys who run these.

Kumho Victoracer V700 -- slightly better dry tire than the AO32's about the same price, lots of negative camber built in.Lot's of 911 guys run these too.

 

for just casual track days i wouldn't do hoosiers, it ends up being a really expensive PITA to have to change tires pretty much twice in every three events.

Mabey the experts can tell us the difference between "R" Compound and the "Pilot Sport Cup" kind of tires.

 

The Pilot Sport Cup is an R compound tire, simply a little more hard rubber added for wear. They take more heat to grip. In addition, the MPSC makes some concessions for rain. Hoosier also makes DOT legal race tires. They wear alot faster than the MPSC.

dum question - what does the "R" in R compound stand for? Race?

 

I guess.

In Europe we call the R-tires = Racing Tires.

But they are not slicks, they are still DOT approved.

Apart from getting a driver's training it's probably the part that will improve your track times the most, not the 20.000 USD engine tuning...

 

I really like the Pirelli PZero Corsa, great dry grip and definitely usable in the rain. The Michelin PSC's are also superb in the dry, but you definitely need to warm them up for any kind of traction. Also avoid the rain with those...

 

As always, the answer is here.

Thanks

 

I was reading the January issue of 911 & Porsche World. On page 10 there is a 'what's new' piece titled: 'Cooper Avon expands trackday tyre range'. Model = ZZR. They say it's the same compound used Group 'N' production saloon-car racing. It's essentially a racing slick with suffucient thread to meake it street legal.

Anyone heard of / used Avon tires?

 

If it is a true '"track only tire" that you are just going to use for DEs why not go with a race slick? You can get them in harder coumpounds so they last as long as a Hoosier, and with more grip. I am going with Yokohama race rubber this year as they make great sizes for 18" wheels. And cost wise, they are a little cheaper than Hoosiers. I am running 320/650 (measures 335 and requires 12" wheel) and 250/650 (measures 265 and requires a 9-9.5" wheel).
