Tire Design Question.

[SoccerFetus8]

Forgive the way this is addressed to a manufacture. I sent it to Mickey Thompson last week, and as I expected no response, so I figured I will start posting around to get some input. Let me know what you guy/girls think and if you happen to be running one or the other or something different that works well for you.

ET Drag, or ET Street Radial???

I have a question or two about the two tire designs listed in the title. I am planning to set my car up with a set of rims and tires for strictly 1/4 mile drag use. What I am wondering is which tire is going to be best for me. From what i know and what seems obvious the ET drag would be the best tire, but here in comes the issue. I plan to run a 15" X 8" rim, this being said the only ET Drag tire that your specs say is able to running on a 8" rim is the #3052 26.0/8.5-15 with the L8 compound and an overall tread width of 8.1". As i stated it seems the obvious choice, but when you compare it to the ET Street Radial #3753R 26 X 11.50R15 with the R2 compound and an overall tread width of 11.3" that is also stated to be run on a 7.5-9.5 rim, I have to question if the added tread width of 3.2" in the street radial would make it a better gripping tire, or is the true et drag slick wrinkle wall design just far superior that it exceeds any difference?

how much Hp is the car making?

[SoccerFetus8]

I don't know for sure as I have not gotten it on a dyno yet, but estimates put it in the 350-375 hp range.

auto/manual?
that must be a wild lt1 for that much hp

Auto, and nope it's no LT1 at all. It's a rebuilt 350 from an older car with some moderate modifications. It's running off a 750cfm speed demon carb. It currently has a stock rear end...which i think will end up having to get replaced shortly after I get some better tires.

ET Drag Radial > ET Street Radial.

ET Drag Radial > ET Street Radial.

Where is this info coming from? I am having a hard time believing that. I feel the 3.2" inches of additional tread width in the street radial would make it a better tire. But there in lies the issue. Get some supporting facts and I will believe you.

Subsection: Tire Choices

"Mickey Thompson ET Drags are the ultimate strip tire, offering maximum traction and consistency. They are availible in both bais-ply and radial construction. ET Street tires are DOT-approved versions of ET Drags best suited for racing classes that require DOT tires. ET Street Radials are intended for racing classes that require DOT-approved radial tires. Due to their incredible compounding and construction, ET Street Radials have proven to be faster than bias-ply ET Streets, but they work best with automatic transmissions and require tuning the car to the tire."

Good enough?

et drag has more traction but will slow the car down
