I wonder why in the heck no one makes a 30 x 9 dot drag radial ?? I mean Hoosier makes the 30 x 9 x 15 radial slick for stock eliminator cars that have to run stock wheelwells. So why does no one make a 30 x 9 tire for street cars that run stock wheelwells ?? I have been running these Hoosier 30 x 9 radial slicks on the street for over 2 years because they fit great and dont rub at all in my 63's stock wheelwells. And they handle pretty good on the highway with my 225/70-15 radials up front. I would gladly use a dot draq radial but everytime you get a 30" tall drag radial they are at least 11" wide. And they will fit the wheelwell but rub way to much on turns so thats why I prefered the 9" wide tires. A 10" tire might work with the perfect offset but I like the 30" tall tire on my 63 as I like how it fills the wheelwell. So until someone make a 30 x 9 x 15 drag radial I will be driving and racing on these Hoosier 30 x 9 radial slicks ! And I will not cut on the car or tub it. Ron

Ron, I know some have had success with radial slicks. But they proved a disaster for me. I tried all the things that were suggested. But my car would shake/vibrate horribly on them. If I recall correctly. MoparBilly had the same problem.

Perhaps if I'm wrong he will see this and correct me. Or offer his experience with them. Jim

Ron,
I feel your frustration, Buddy! Looking at the tire charts, your current slick is 29.5 tall, 11.3 section width, and 9.0 tread. We ran a similar drag slick on my 67 Belvedere with no rubbing issues, but when we would switch to the 275/60/16 street tires my brother had on it, it would rub in corners, and when loaded. I didn't want to change tires on Drag Week 2012, so I went in search of a multi-purpose drag radial, and ran into exactly what you are talking about.
My first concern was no rubbing, so I settled for Mickey Thompson ET Street Drag radials in the 255/60 size. The section width of 10.1 and tread of 9.0 are great, but they are miserably short at only 27.1! The 275/60 MT's are 28 tall 11.0 section, and 9.5 tread, so technically they should fit anywhere a 30X9 slick would, but I have seen guys really struggle to get that tire under many stock tub Mopars. What we really need are Drag Radials in a 70 series, but controling that large of a sidewall seems to be a problem for them.

The 255/60 M/T ET Street Drag Radial performed flawlessly on Drag Week, as They drove through a torrential rain on I-40, and maintained speed. On the drag strip, it never turned a tire, but the 67 leaves really soft, and only went 11.58-116.

My Valiant takes a big tire no problem. On Drag Week 2011, I couldn't make the 315/60 Drag Radials work on the track, but they made the drive, even in rain, just fine. In 2012 I changed shocks on all four corners, and went with a bias-ply Et Street, which is basically a slick with a couple of squigly lines. Great on the track, and great on the drive...until we hit rain! Then they were completely unsafe at anything over 25 MPH!!!

My cash is tight right now also and I need new tires. I could go to a 28 which should look ok in my rear wheelwell but then I would have to gear down as I dont want to run 28" tires with my 4.30's. Later when I get the cash I plan to drop to 4.10's or 3.91's and then 28's would be ok but it would still be better to stay with 30" tires even if I drop to 4.10's or 3.91's as with the 493's torque I dont think it would slow down as heck it might even go faster and would have a better cruising rpm. Right now with the 4.30's and the 30" tire I turn about 3200 rpm at 60 mph so I would love to drop to 3.91's and stay with the 30 inch tires. I really think it would still run 10.70's or maybe even go a tad faster as when I short shifted by mistake last time at the track it still ran a 10.83 with ease. I had accidently shifted to second about 5k as I usually shifted about 6000 to 6200 but like I said it really did not slow me at all as I was only running 10.80's that day in the heat at that track which I am usually a good 1/2 tenth slower at that track then the track I ran 10.70's at. But I cant afford both the tires and gears right now so I plan to get the 30 x 9 Hoosier radial slicks for now as I have a spare set of rims I could use to mount a dot tire later if I get the extra cash and gear down. I am seriously considering going to 3.91's. I wish I could try a 31" tire first and see how the car likes it as I can fit a 31" tall tire in the stock wheelwell. Thats another reason I like the B-body wheelwell over the Dart A-body small wheelwell I had when I owned my Dart. Ron
