Theres a reason for that. What does happen though is the steel cords in the sidewall will begin to break. And the sidewall takes the most pressure on a tire so dropping pressure, driving on it, then airing them back up is very bad. Sometimes you will hear cords popping when you air it up again. When it does go it will probably be when your doing that.<br /> <br /> <small>[ April 07, 2003, 02:04 PM: Message edited by: Fast477Mach1 ]</small> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Chris M.</b> <br /><small>Member # 1708</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,3,7,16,11,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> people run mid 9s on a 275 drag radial, some of them have wheel screws holding them on like Fast477Mach1 pointed out. <br />I wouldn't worry about the steel chords since those tires shouldn't last you more than 2 months. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>TRY2PAZ</b> <br /><small>Member # 97</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,3,7,16,56,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> You can air down your tires if you want. i use to run my street tires at 25psi.

And after the racing is done for the day, it is essential that Drag Radials be reinflated to normal highway operating pressures in order to safely bring the driver and trophy back home. Running any tire at relatively low inflation pressure for a given load reduces the tire's speed capability by causing it to stretch more and operate at a high deflection (more radial bulge). The Drag Radial is built to withstand brief "bursts" of high speed while inflated at low pressure (such as would be experienced on a quick car in the quarter-mile), but no tire can be expected to survive for a long time at high speed while operating at high deflection. To date, the Comp T/A Drag Radial has been successfully used on cars with quarter-mile ETs in the low 9-second range, and trap speeds in excess of 150mph.<br /> </font><hr /></blockquote><font size="2" face="Verdana, Arial"> <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>hopdup95</b> <br /><small>Member # 2381</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,3,8,8,45,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Thank you guys for all the info.
