George,
MPSCs behave very much like real racing slicks. They need to get well above 150 degs to stick. I think slicks go at least 40degs higher. To get heat in them, you must cross the slip angle alot. Nope on middle of summer for running them. I have run them in 40 to 50deg dry weather and posted the following times on my track computer: Glen: 2:13xx, VIR 2:12xx, Summit Point 1:23 flat, Pocono North 58 flat, Shenandoah 1:39. The laps also are consistent and include 3 or 4 laps in a row at DE's so race times would be a little faster yet. With proper car setup, they are about a second a lap slower than Hoosier R6s.
I strongly recommend DE drivers learn on these tires (heavy cars around 3000 lbs especially) as they help understand how to get a tire to temp quickly. They last along time, do not need excessive camber; fall away gradually; and tend to have a wider grip to slip bandwidth. Running new Hoosiers at DE's ( at least new ones) makes no sense as it is a lot of money to get those one or two session trophy's. Used, older Hoosiers are also great for learning on, but leave the good tires for racing and qualifying laps or time trials where 10ths matter. You can buy Hoosiers that are scrubbed in from racing teams at a fraction of the asking price.
