Default Street Touring Tire Choice 2009

Looking ahead at the tires available to us for the SCCA ST* Solo classes for the 2009 season.

I think thereís only three choices:

1. Yokohama ADVAN Neova AD07
2. Bridgestone Potenza RE-01r
3. Dunlop Direzza Sport Z1 Star Spec

I run STX. Iíll campaign the Dunlop in 245 40-17 shaved to half tread for 2009. Ran the Bridgestone for 2008 shaved half tread. Loved it.

TireRack has the Dunlop rated the same for dry as the Yokohama both better than the Bridgestone.

Kumho Ecsta XS is legal and is fast on the West Coast. I'd actually go ahead and remove the Neova from your list, it is slower than the others in testing and cost an arm and a leg.

Remove Bridgestone, too. The Dunlops are far superior in everything but treadwear.

I thought Yoko is redoing the Neova for 2009. Even still it would have to be give r-comp performance for me to pay the crack prices they ask for them.

The RE-11 looks promising, and I'd like to see what the Kuhmo does.

You want 235/40/17 on WRX, not 245/40/17... shorter gearing.

As BrianGT stated, there are 7 possible options for next year. The Dunlop is the proven tire at this point, and where I would place my bet if I needed tires in February/March with a small budget. Luckily, I'm getting some nearly used up Dunlops that should get me through to mid/late May and let others do all the testing on the new stuff. But for cost/performance, I think its going to be either the Dunlop or the Bridgestone RE-11 as the tires to have next year, with the RE-11 getting the nod, especially with all their ST* support.

IIRC, some super secret tire testing was done with the RE-11 and Dunlop, with the RE-11 hinted at to be the better tire. Unfortunately, I don't think the "official" outcome of that test was revealed.

Yoko's...yeah, sorry I don't have a money tree in my backyard.

I'd still love to try a 245/35/17. I would be a bit nervous of running out of gear on a faster course.

I think only the Toyo's are even proposed to come in 245/35/17. I'd run the Dunlop in that size if it was offered. So it's either 245/40 or 235/40.

its the height of the wall not the width that affects the gearing

But for the same height (i.e., 40 in this case), a wider tire is taller. The "40" is a ratio to the width.

The "wall height" that you refer to is actually the aspect ratio, which is the ratio of the sidewall height to the width of the tire. Wider tires with the same aspect ratio will have a taller sidewall than a more narrow tire.

EDIT: wikipedia article on how do decode tire labelling: http://en.wikipedia.org/wiki/Tire_code

Tire competition is fun! Here's some pictures of/links to some of the newer tires.

Hankook Ventus RS-3



Advan Neova AD08



(Above two from http://citytireonline.com/news/)

Bridgestone RE-11



Image from here. There's a (p)review here. My Japanese skills are really basic, but I'm pretty sure they're saying it's good.

As mentioned, there's some people running the Kuhmo XS where it's still warm. Any more info? I also think the NT05 could be decent, but Nitto needs a better size selection (not to many in 17s listed, but lots of 20s?).

I'm probably going to go with the Star Specs since they are a lot cheaper then the RE01Rs/RE11s, but I know that the RE11 will probably be the better choice. Guess I'll have to see how baller I am around March when I get a set.
