No no...don't sand anything. Just email me or post a clear picture of the face of the rear wheel. I'll be able to tell you right away which wheel it is.

I haven't

ok i will
im currently in boston.
the wheels are on long island , ny with the car.
i'll see if i can get pics sent right now.

btw tom, i probably should have consulted with you ( i spoke with Victor at your motorsports division today) about tires.
i went with toyo r888 235 / 305. u think i'll be ok with a 305 on a 12" wheel ?

Yeah, you'll be OK with the 305. The Toyo's are pretty chunky so they won't look stretched.

i scored a set of PERFECT magnesiums for $750.

Then I'm really going to hate you!

You can see the wheels here Tom.

The joke would really be on TPCRacing, who not only poorly ran a sale, but were ignorant enough to sell magnesium wheels for $750 Frankly, the posted weights in the ad don't seem low enough to be mag wheels, so something seems odd.

I'm personally running some RG5s with Michelin Super Sports in 305 on 19x12s and they fit perfectly. I need to post some pics, the SS have very significant curb protection, making them perfect to run on a 12" wheel. Also the 44 rear offset is ideal, I thought it would be too aggressive, but it isn't at all. Ill need to post some pics.

R888's

Not sure of your experience level, or how often you plan on tracking but the smart move may be to just get a set of track wheels mounted with the tire you want.

i have a few sets.
one set is my gt3 rs wheels on michelin pss tires. <~~ daily wheels
my 2nd set are my champions w/ toyo r888;s <~~~~ wheels for spirited runs/rallies, tracks, events, 60-130's , etc
ii have a set of iforged deep dish 5 spokes that i will use as winter tires
and my oem 997 wheels i will use for 1/4 mile events only and run narrower tires.

i dont have much track experience. im probably going to be using these for some backroad twisty runs.

Personally, I'd stay away from magnesium used racing wheels. They tend to crack.
If you're not an experienced track driver, the 888s will be a waste of money. I'd run pure street tires, they give the needed feedback at your skill level. Once you move up to solo intermediate, only then would I mount R cmpds.
Not knocking your driving skills, just telling you the truth.

Steve, I am going to hate you for this.

Re. R888, for twisty canyon roads the R888 will be perfect! For 2 reasons, handling and adhesion. I've compared PS2 vs. PSS vs. Pirelli Corsa and at the limit there is a significant and easily reproducible difference.
Handling wise, tire stiffness is part of the suspension and as you've noted and body lean will be much less, steering sharper, etc.

For the sake of discussion, with respect to traction, one does NOT have to go at extreme high speed to appreciate the increased in traction of a tire. The key is the limit of adhesion regardless of speed. Say there is 30 mph corner, and now you start to slowly increase your speed in this curve, to 35, to 40, to 50. A street tire will break adhesion at an earlier speed than R compound, say 40 vs. 50. You don't have to be Shumacher to appreciate the difference in traction. Do be careful and only test limits once you have some time with the tire and the car though - slow in fast out applies regardless of skill level.

This is the same reason that autocross guys look for stiff walled, high traction tire. They sure are not doing 100 mph but the stiff wall and high traction help for reasons above.

From personal experience, the R888 is the best choice for track days/DE for several reasons:

Pros:

1. Cost - cheapest R-compound available at TT stock sizes. Would probably last longer than the MPSC or Hoosiers.
2. Traction - definitely better than stock (RE050 is the only one I experienced). Probably less traction than MPSC or Hoosiers.
3. Convenience - can drive to and from the track with these tires, even in the rain. In fact, I know a guy who drives a Cup car at the track who uses these as his rain/wet track tire.

Cons:

1. Noise - these tires howl even when new, at any speed. But then again, at the track it doesn't really matter. As daily drivers, aftermarket exhaust will probably drown these out anyway.
2. Ride - very stiff sidewalls, ie, harsh ride unless you go down on the tire pressures.

Conclusions:

Probably a well-rounded tire for a TT that is driven on the weekends around town with the occasional track weekend. Alternatives include MPSS (more quiet and supple ride, lasts a long time, great daily driver), Pirelli Corsa (don't have experience with these), RE-11 (lots of feedback from track junkies on this forum. I'm on the fence whether this or the RS-3 is my next tire after the R888.), and lastly RS-3 (which is actually very promising, bit more expensive than R888, but offers excellent traction, longevity, ride, and noise from my experience in another car). Again, these are just my opinions on these tires from experience. Others are welcome to add/edit/criticize.

Correct.

Also another vote for Pirelli Trofeo. I'd rather run Toyo R888 than Michelin Sport Cup for 19" sizes.

R888 have had an issue of tread seems splitting lately. I had to send 4 R888 back to tire rack. I've had 6 split on me in the last year and a half.

I didn't have this issue a few years ago and don't have this issue on the Nitto NT01 I'm using now.

Dont forget that R888 and Michelin Cup-s are terrible, when raining. When its just wet, they are OK, but when on road and you get some modereate or heavy rain car feels like a boat. All that because R888 and Cup have very low tire pattern.

mdrums, do you happen to know if other users have experienced this also? Or more like isolated incidents with you/your car? What does Tirerack say?
How does Nitto NT01 compare to R888 with respect to noise, handling, and traction? TIA.

For anyone interested, this is what I believe mdrums is talking about, from Tirerack:

Tire Inspections Between Sessions
Tire inspections between sessions should be used to remove all rubber pickup from the wheels and tire treads, as well as offer an opportunity to examine the tires for punctures or cuts that might lead to compound tearing or air pressure loss. The inspection should also confirm if each tire's tread compound splice (that runs perpendicular to the direction of travel across the tread area) has become visible.
Visible Tread Splice: Rotate Tire

Torn Tread Splice: Replace Tire

A visible tread splice is caused by tearing open the tread compound junction at the tread splice. Visible tread splices are caused by the torque of the engine spinning the tires during acceleration or the stopping power of the brakes briefly sliding the tires when slowing from high speeds. Front-wheel drive and most all-wheel drive vehicles place extreme stress on the front tires from both acceleration and braking forces and are therefore more likely to see these visible signs of use than more balanced rear-wheel drive vehicles.
If a visible tread splice is detected during tire inspections, the tire should be rotated side-to-side on the same axle. This will then use the vehicle's wheel spin to close the splice rather than continuing to open it. While this may cause the tread splice to become visible on the other tire used on the same axle, the inspections and side-to-side rotations should be repeated until the tire has worn out.

NOTE: Continued use of a tire with a visible tread splice in the same wheel position will cause the tread compound to tear downstream from the splice, forcing the tire to be removed from service.

Are these only available for 18s? can't seem to find them for stock rim sizes.
