The answer is simple.......you do NOT spin a drag radial. The tire is dead hooked or it is spinning, there is no in between. They also have a stiff sidewall, but it is not so much about the sidewall as the "hooked" part of it. Slicks "give" because they wrinkle up as well as black track when you hit them with real power. Radials are "hooked" and put ALL that power through the driveline. If there is a weak link, you will find it.

Walk through the pits at a race and look at the FAST radial cars. I am talking about the ones that run low 4s in the 1/8 and 60 foot in the 1.0s. These cars have massive power and are dead hooking the tire. They are built like Pro-Mods for a reason, they HAVE to be. They all have Pro-Mod style rears, with many even having floaters. Twisted and broken 40 spline axles are common, as well as broken chassis', ripped out 4-link brackets and bent housings. Many have now also gone to the Top Fuel type center in the rear wheels. These cars BREAK parts and bend up stuff, if not properly built.

Here is a graph of a 4.16 pass with a 1.06 short time. Notice what you DON'T see in the shaft speed.........tire slippage................ and the Gs are over 2.6 at the hit and climb to well over 3.4. That's HARD on parts
