M/t radial problem

Dennis Paz · 03-15-2010, 09:21 PM

I have a set of the 12.25 w radials with maybe 25 passes and all of a sudden car is way unstable on top end, put old bias plys back on and car is perfect. What gives??

TOO FAST?
Gotta say I am plesantly surprised especially after the 3 tenth chop.
These tires S U C K! ole worn out bias ply hoosiers way more stable on top end.

I dont know anyone at M/T, Is Carl in so/cal?
Not a balance problem as car is smooth, feels like running on flats with 20 psi.

One thing I have found about radials, they tend to do that if the wheels aren't wide enough.
Mine totally stopped doing that after I learned to use wheels wider than the tread area of the tires. I put my 9" radials on 10" wheels, and my 10.5" on 12" wheels. Made a whole new car out of mine. I can run more air, it hooks harder and no more wobble.

I've run these tires on my S/Stocker for several years with great sucsess . At first I ran them with a 12" rim and had some wobble . Since going with a 14" rim I run approx 18lbs of tire pressure and I do have a sway bar My truck is absolutley stable no shake . Also about 8-10th quicker and have consistantley put over a hundred runs on them . As in any radial tire make sure all suspinsion is tight .

I agree the wheel width does seem to have a distinct effect on these tires, wider wheel is preferrable. Joe
