The Drag Radial Thread v.1
There are a ton of drag radial questions floating around every week, I think someone needs to clear things up.
Mickey Thompson ET Street Radials:
Best at the track, not good in wet weather, and they don't last very long. If you haven't broken anything, you will with these tires!!
Sizes common for f-body/Corvette
275/50-15
275/60-15
295/50-16
315/45-16
275/40-17
295/45-17
315/35-17
305/35-18
345/35-18
Hoosier DOT Drag Radial:
Very sticky, one of the best hooking tires as well. These are DOT stamped but Hoosier does NOT recommend these for highway/public roadway use. These are more for 100% racing and will not last long.
Sizes common for f-body/Corvette
275/50-15
275/60-15
295/65-15
315/60-15
325/50-15
275/40-17
315/35-17
335/35-17
M&H Racemaster Radial:
Also very sticky, as you can see very similar to the Mickey Thompson. I don't know much about these tires as they aren't as common as the others, but I wouldn't imagine them lasting very long, and they probably lack wet weather traction. Sizes run thin! Their 390 width is actually 12" wide, so don't be fooled.

390/40-17

BFG Goodrich G-Force Drag Radial:
Decent on the track, decent in wet weather but you have to be careful. Not very long lasting. Sizes usually run pretty wide.
Sizes common for f-body/Corvette
275/50-15
275/60-15

315/35-17
295/35-18
315/30-18
345/30-18
Nitto NT555R:
Not so great on the track but stickier than a normal street tire. Pretty decent in wet weather and decent treadwear. They work well when you heat them up good (John Force burnout). Good choice for a car making around 450rwhp or less. Sizes usually run somewhat narrow compared to other manufacturers.

Wheel diameters
A drag radial on a 15" wheel will outperform bigger wheel diameters because the sidewall can flex more, and have a very slight "wrinkle" effect that larger wheel diameters cannot have due to small, somewhat stiff sidewalls.
Notes/Comments: (From Pro Stock John)
Wheel Hop - When you get wheel hop don't stay on the throttle you have to let off. Staying in it can result in broken wheel studs and rearends.
Suspension/Tire Pressure - When tuning a drag suspension at the track with drag radials, you want to run as much tire pressure as you can until the tires start to spin. When I've used 325-50-15's for example, I've started them at 18psi, and last time put them down to 17psi on my 1.35 pass. You want to keep the wait of the car on the back tires, so make sure that the car does not come out, up, and then down and unload the suspension. Doing that can result in tire spin and wheel hop. I run QA1 R shocks up front, and in back. I last ran the fronts at 1/1 and the rears at 7/7. Hope that helps.
Feel free to input.

You should say Mickey Thompson ET Street Radials, a newb might see this and order himself some ET streets and be like "wtf mate?"
Also you might add the M&H tires although I personally can't vouch for how well they work.

The nittos work very well as long as they are hot. If you let your car sit for a while you need to do a pretty good burnout to get them to grip. The are the best moderate HP RWHP DD tire IMO.

Thanks for the input, I'd like to make this a sticky due to all the recent questions on drag radials.

<-- is a cause for these types of threads.
Lol all i'm doing is looking for a decent daily driver drag radial. Everything has its ups and downs..
whats the biggest tire size you guys have fit out back on a (preferably) lower car? I'm thinkin of puttin a bit wider tires but dont want to rub anything
