R compound tires.

[chaos4NH]

Looking for advice, and hope to get recommendations, on picking some R compounds for the red wagon. Fairly heavy car, 3150#, about 60% - 1800# on the front.
On the less expensive side, Stephan, how did you feel the NT-01's performed? Has anyone run Avon Tech Ras? BFG Geforce R1s?
Kumho V70As?
If it matters, I can run 225/45-17 or 235/45-17.
Thanks to all!

Kumho Victoracers have been known to work well on heavy cars.

3150 is heavy, eh? I've been running RA1's and they have been pretty decent in terms of grip vs. longevity. I might try the Nittos next.

Sam,

I have some old Kelly Springfield bias ply tires left over from when I used to run an Austin Healey with COM in the 'Sixties. Might be just what you need.

Toyo RA-1, shaved to 4/32". Sticky and very consistant. They will be sticky to the cord! A favorite of mine for many years.

If you are moving to race rubber, you might want to evaluate your alignment settings and dial in a bit more camber.

I agree, my 3 years old RA1 is still setting good times, runs forever and have no problems. Heck, they are ride smoother and make less noise than my street tires.

Frank, I am at loss for words! Such generosity! That might save the bucks I need for the coil overs and camber arms, though!

Thanks guys. At this time the RA1's have the edge, but no decision until all the votes are in. I found 235/45-17 RA1s fpr $213.95

I had Yokohamas, Kuhmos, Toyos and Nittos. Here is my 2 cts:
Yokohama = definatly a rain tire, awesome rain tire. Beinf the rain-man I am I absolutely count on those and had great results;
Kuhmos = good tires but wear out fast.
Toyos = great tires, reliable, long-lasting, forgiving (when you spin) and good prive for the quality of the tire. I measure the price of tire like I rate a good wine .. it's all about price/quality ratio.
Nitto = Tried it at WGI and had a grea time with it. Felt it fast faster than the Toyos and equally reliable. Minor peeve was it squealed like a street tire at times but hey! who's listening? Great price/quality ratio.
If you do't want to spend $$ on Hoosiers my 2cts is go with Nitto.
Hope this helps.

Did you have full tread or shaved Nittos? Do you think the full tread Nittos grip as well as shaved RA1's?

Hey Frank -- if Sam doesn't want your old tires do you think I could used them on my Mustang The light Mustang has a tendency to eat up rubber but those Kelly Springfields should last a long time

The Avons are not very quick, but will last quite a while- BTW they are THE most difficult R compound tire to mount. I wasn't aware of BF Goodrich getting back into the R compound market again until your post. The last generation of R1s had a habit of forming a groove of doom right down the middle- even when not over-inflated. I'm sure the new tire is better. I would use the Kuhmo 710 again, as I've said in other threads, the tires do fall off some after several laps in a heavy car, but they do stabilize- they do not continue to fall off. They are great time trial tires because they come up to full stick very quickly. I used 1 set of 710s in a full championship season.

"Minor peeve was it squealed like a street tire at times but hey!"

Stephan, I thought the tire squeel I got at WGI was odd as well- I was on 2 year old Hoosiers (Thanks Greg R.)

I was using Hoosiers R6 that were new for Lime Rock in the Fall , and I thought I was on regular street tires with the screach they made at Watkins .
I have never had the Hoosiers squeel like that

Also thanks to everybody for a great time at WGI and the "Birthday Card". I got passed by Ryan C and Joe L in the ST1 and than they even passed me on the highway on the way home. I guess life has just passed me by I did get a 2nd in STGT though

I'm running a set of RA1 scrubs that I bought from the Bimmerworld World Challenge team. $50 or $100 a tire depending on how many heat cycles they have on them. They're currently backordered but you can e-mail them and ask when they're going to "make more".

I've had pretty good luck with them on my 3650# GTO. Because of clearance to the strut, a 245 is the biggest tire I can put on the front. I have 3 track days on this set and I'm sure they've got another one in them though I probably should flip them on the wheels to put the good edge on the outside.

[Subw00er]

I ran the hoosier r6 at wgi. This is my first r compound, but I like their feel. They grip like snot!

Hi Raj: The NItto-01 tires are designed to get go right from the shelf, not requiring heat cycle and/or shaving. This is another advantage of this tire vs. Toyo or Kuhmo.

Glad to hear (from Scott) that he got squeal so I can dedcut is related to track surface.
