Hoosier Tire question?

[Live4DLM]

Can someone explain the difference in 1100,1200,1300...etc and LM-10,LM-20...I always hear the 1100 series tires are synthetic rubber and the LM series are pure rubber....Also why would you run one over the other? Just wondered what the scenario would be for running either tire in open rule competition

I could be wrong, but I don't think Hoosier makes a 100% natural rubber tire.

Don't run an LM tire unless the rules force you to do so.

I remember a little of the interview after Bloomquist won the Colossal in 2006...he said he had LM 20 on the front and the rest 1600....Madden had all 1600 and Owens had all LM 20's...just thought that was strange.

An LM 20 cant take half of what a 1600 can take. It would be very odd for fast cars to have 1600 on some and LM 20 on some on the same location of the car. There is a lot of rubber choice in between those for an open show.

If conditions were favorable for it, I would run them on the front, but not the rear. The LM is a narrower casing than the open tire.

The LM10 falls inbetween 1100 & 1200, LM20 between 1300 & 1325, LM30 = a 1450/D45, and LM40 =1600/D55. I know there have been variations of 1450's and 1600's, but as far as I know its the standard compound. Construction is a whole different deal but thats how the compounds line up according to Hoosier.

a lot depends what type of clay/dirt/soil/sand/rock you're running on because some of the tires needs a lot of friction to make the tire work, some need wet moisture, some like abrasion and some don't like any abrasion. Hoosier just recently changed the 1425 rubber around but a 1350 is actually harder than a 1425 if you use a durometer. The 1325 needs abrasion to work like the 1450 but the 1450 needs to stay hot to work. We can go on all day long about tires but what I understand is just as PAMudslinger said about the comparison of the lm - economy series
