time for new slicks

[spookie]

My FED runs 5.60s with 1.20 60ft times in 1/8mi.Have been using Hoosier 32/12-15 DO5,with tubes. Should I loose the tubes and is there a better tire for my 12in rims The Hoosiers have worked good with 6 to 6.5 psi,over 375 runs

I am very happy with the M andH 12x33 tire !

I'd try tubeless.

I too love my M&H slicks.  Great service and they are the most consistent tire I've ever ran

Go tubeless.  I have run 33X12x15 CO9 Hoosier for 9 years. 5- 9.5 lbs depending on engine tune. Always stuck best 60ft was a .93 blown and a 1.01 NA. Going tubeless will lighten your tire weight up a bunch.

I ran the Hoosier 31 X 12-15 for years. 12" wheel, no tubes, screws on both sides. I don't see the same tire listed today? I ran 7psi with 4.30 gear and a 1.69 primary. Ran 4.50@158 on a good track. Bruce Browning is my to go to guy at Hoosier tire Midwest in Springfield Illinois.

which M&H are you fella's running? In case these new M/T's don't work out.

Be carefull about comparing 60' times, a car with overhang will have a lower time then a straight up car because the car with overhang is 24" further that the start beams thus the time is based on 58' and not 60'.  Other racers times don't mean a toot as long as I can hit my index.  My car on 33x12x15 GY on a 10" rim(tubeless) with a 3.90 gear  runs a 1.09-.10 60' without overhang, ands hits the 7.0 index. Tire compound only comes into play if you get new tires frequently, if not all compounds equalize after time due to runs/heat cycles, sun light, age. I can say that because by the time I get new tires, they don't have that compound in stock or they changed/discontinued it., put those on, car runs the same.
