I will do more autocross than Road Course events, and I will be driving to the autocross events with the tires on. The Road Course events I will not drive on the tires, b/c of the distance to them and I would be worried about the rain.

RII
RI are for drag racing

While the R is for drag racing, they actually work OK for road course use. The RII is preferable for road course use, but comes in very limited sizes. You can definitely use the R on the back; I know several people who have done this with excellent results. The 555R isn't nearly as much of a drag radial as something like a BFG.

Definitely the R2's for road course and autox.

I don't know how the R's would work for drag racing and autox since you'd think that a drag tire should have a soft sidewall for straight line traction.

Since you like Nitto have you looked at the NT01 tire.

I would like something that can perform somewhat in the rain. What site has good prices for BFG? I like those also.

I think you are asking WAY too much from one set of tires. You want a tire you can drive to auto-x events, take to the track, work well in the rain, and has the grip of an R compound?

The 555R and 555RII are great tires. Not quite as grippy as a real R (like a Hoosier or V710), but they last a really long time. The 555R isn't a real drag radial, more like a really grippy street tire. The 555RII is just a 555R with 1 extra sidewall ply. Even the 555R will work good for road course/auto-x.

If you want to drive in the rain and drive to events on them, just get street tires.

I ran the BFG KDW2 last season. I did have about 9 track days on them. They have a lot of tread left but they are not as sticky as they were. I think that for the price they are a good all around tire. I use to run Nitto NT555 street tire. I ran them on my Lightning and Must/Cobra. Great all around tire although more expensive.

Tire Rack for BFG and Discount Tire for the Nitto.

After thought: Full depth tread does have a tendency to chunk bits of tire.

Anything dual purpose is a compromise. That said, you might think about Toyo Proxes T1R's (UTQG 280 grade) or RA-1's (100 grade - with 8/32" thread to start). They're structurally and composition-wise similar to Nitto's ... google Toyo Tires to find a source.

Discountedwheelwarehouse.com as good prices on Nitto's- I think I am going to go with the 555RII's in 275-40-17 and 305-35-18 on stock C5-Z06 wheels- and drive to and from track and of course track time.

Will the performance upgrade be sustantial over the GY- SC stock tires, or incremental ?

MungoZ06

Performance is between the stock F1's and Kumho's. To get the most out of them, you need to add camber, as they stick well and will heel over and you only use the outer third of the tire.
You can drive them to the track, but be wary of standing water, e.g., truck ruts on the roads. I'v had them on the track in the dry and under light drizzle conditions.

I think you miss understood me. I never said it needs to have the grip of an R compound. I would like to be able to drive to local autox events and if it rains out of the blue...I don't want to have to worry about loosing control. So something that can allow me to get to local events safely in the rain. Now as far as road course events I will haul my car up to it anyway, so I don't have to worry about the rain. Therefore with that info, what would be a good tire to get?

Hi,

My vote is for the Nitto R2s. I just got back from LimeRock. My tires are from 2004-but still managed low 1.04s all day on a very cold track and finished 2nd in class. Then drove back home in the pouring rain (approx 135 miles) to Long Island, NY.

Great all around tire!

Only issue is speed. Even my C5 coupe on Z06 wheels with 275's up
front, Kumho MX's, will hydroplane at 65 in standing water. Less tread
and same width, you have to slow more. I like the MX's for combo tire
on track and use for street but not as good as Nitto or Toyo at the
track.
