I have an old set of 29" Thornbird tires just collecting dust in the barn. I also have an old set of '95 15"x7" mustang wheels. I haven't measured the back spacing but they are pretty deep. Will these tires fit on a stock CRD? I know some caliper grinding is in order on the front.

Check the DOT #'s on those tires,the last 4,and if there older then 10 years you shouldn't run them on heavy vehicle like a CRD,not to mention thornbirds just suck anyways.

If the 15x7's are alloy they will not fit unless you get the backspacing to 3.5" or less.


Never,never,never grind down a caliper,just plain unsafe.

Ya they are alloy and somewhere in the 4s. The tires are like 5-6 years old and yes they sure do wander on the black top, but they do pretty good in the snow and mud. I have a set of stock Cherokee wheels that are steel.

Stock steelies will need spacers also.Aftermarket steel 15" rims with 4" or less back spacing is what you want/need.OE 15" wheels have to much BS and will hit the caliper and/or the outer tie rod ends.

Sell the tires if you can and get something that works good on the KJ
wouldn't be worth the effort to mount up the Thornt*rds

This has been done??????

People do it on the rear calipers on 4th Generation F Bodys (Camaro / Firebirds) to fit 15" Slicks. Grind down the cast fingers that are on top of the caliper.
