Baby needs new shoes. I need some open track tires for the stock '02 wheels ASAP. I need to order them tomorrow so I can get them installed next weekend (March 8,9 open track event at California Speedway).

I am leaning towards some heat cycled (but not shaved) Kuhmo Ecsta V700's in 265/35-18.



Any thoughts?

I still have probably 4/32" left on the F1's. One tire has been plugged and the other is sporting a screw. I always have the option of having them properly patched and using them up. Should be a total of 8 15 minute sessions over the two days. Any thoughts on whether they would last two hours?

 

Those tires wont last 2 laps on your truck due to the weight and size.

However, i bet the Toyo's will work for you and Mark at Lightning Force Performance has them in stock.

Incase no one knew, Goodyear has increased the cost of F1's by $60 to its dealers.

 

As far as patching the original F-1's
Both of mine have big plugs in them that I did myself right then and there when they wen't flat One happen 3 days after I bought it, and the other within a month. I've been driven on them for over 9k now and never had a problem. I raced on them all summer, I drive it everyday, I do high speed runs often.

 

i know! that why next time im getting comp t/as or geforce t/as, just havent decided which ones yet

 

toyo proxes! best choice ever, 1100$ installed was a bit much tho

 

What about the Michelin Pilot Sport Cup?

 

I'm glad someone brought this thread up. i didn't have big enough ***** too. I'm tired of not having any stink'n tire choices for the stock size wheel.

 

He did say open-track tires, not street tires.

Those Khumos are a bit small, you might risk over-rev if you're not accounting for tire size difference in the chip. There are a set of Pirelli Corsa's that are around the same size that would fit too, OneLap ran them.

GoodYear Eagle F1 GS-CS
275/40ZR-18 (26.7")
GS-CS's are molded to 3.5/32nd racing depth.


Pirelli P-Zero Corsa
235/40ZR-18 (25.4")


Toyo RA-1
275/35ZR18 (25.6")

 

Some good street tires:

Pirelli P-Zero System Asimmetrico
285/45YR18 (28.1")



Toyo Proxie T1-S
285/40ZR18 (27.0")


Sumitomo HTRZ II
285/35-R18

My oppinion. I would go with the Toyo T1 - S Ultra Performance. 285/40 18. Y speed rated

They also come in 285/35 18. But like everyone said. Our trucks are heavy. Think the 285/40 18 holds 200 pounds more in weight rating.

 

The T1-S is more of a ultra-perofmrance street tire, not a track tire...

 

Thats the only ones that will hold the trucks weight for the stock wheels. especially under high cornering loads. they use ultra street compounds in bike road racing. they did when i raced. pirelli dragons. those things went the limit.

If he used a real race compund for that thing it will eat them up. especially the torque our trucks put out. to get anything he would need some different wheels. the street compound i think would be perfect. they are hard, but our heavy trucks will keep them at optimum temp for traction on the track

 

I run BFG R1-A r-compounds without any problems on weight limits. I would keep running them if they would have kept making them.

My Pirelli's that I run on the street are rated for 1900+ lbs, which is higher then the F1's that come ON the truck.

I'm assuming thats a race compund. man! do tell.

yeah, i trust pirelli to great extints especially with the raceing i have done. they make some great compund that scars and tears down perfectly.

i would run them but i don't want to stray too far away from the 295. I'm happy someone pointed out the toyo's i overlooked them i guess. they might be my next set. wish they have more info on their sight about them. looks like those tires will break down nicely. just wondering how long they will last?

 

Its rated per corner, not the entire weight of the vehicle on one tire.
