How much clearance do you like to see in front of the rear tires? This is on a 29.5x10.5 bias ply.
Thanks

wondering the same thing I ma fitting a larger set of radials tonight and they siy very tight, would expect more clearance needed for bias vs radial to allow for tire growth, have heard that you should allow for 1 inch of tire growth with bias, so this would mean a minimum of 1/2 inch clearance at the front,not sure what is needed additionaly to allow for the tire wadding up on launch ?

My Charger runs the thickness of my index finger (~5/8") from the tire to the front of the wheelwell where it tucks in at the bottom. I have no signs of contact with my 28x10.5 M/T ET Drags.

The clearance needed is dependent on the car and how fast it runs, a 12 second 112 MPH car can probally get away with 1/2 inch or so, a car that runs 125 MPH needs more like 5/8 inch or more like 67Charger is saying

Sorry to hijack but what about to the leaf spring at the front and rear of the tire.

Jesse,

Clearance from the inside of tire to the spring
should be at least 1/4" if not more.

Since you really need to run 3 inch studs you
can adjust the clearance with spacers.

You can buy spacers usually in 1/8", 1/4", 3/8"
and 1/2" thickness's.

I've seen one 68 Cuda with S/S springs and 8"
rims and at least 275 tires and he only had
about 1/8" clearance at best, but he had stock
lug nuts and no spacers for clearance.

He was chewing up the inside of the tires.

Hey Phil did I tell you I hate figuring this rim stuff out. I got three inch studs and all kinds of spacers.

Thanks, I have 1 1/16" clearance...car will trap at over 130.

Thanks Bigdad!

i have the same,well did,i got some 29.5x295 street radials going from 28x10.5.the gap will shrink but the tires wont grow that much.have fun.
