67 GTX Tire and Wheel Size Change

[bennysmopar]

I want to fill the wheel well a little better on my 1967 Plymouth GTX. The 14-inch rims just don't do the trick; I have a set of new 15' X 7" Magnum 500's at my disposal and would like to use them. I have a DANA 3rd member, and a plain front disc brake conversion kit from DR, DIFF (nothing fancy), stock 11" X 2 1/2" rear brakes. He said the 15 wheels will clear, I have stock suspension, but what size tires can I comfortably use without rubbing? Has anybody did this?

A 245/60 might fit but I don't know for sure what the width of the dana is.

I like a 215/65 on the front

Thanks Don,

I bought 235 70 15 for the rear and 225 70 15 on the front of my 67 R/T. The only time I have had any rubbing is an entrance to a filling station that the entrance is a sharp uphill right. But is minimal as I have found no scuffing on the tires.

I second that a lot can depend on the Dana’s width. That and the 15x7 Magnum backspace may not necessarily be ideal for these cars.

A 225-70x15 on all 4 corners would work nicely with 7" magnums

P 255 60s on 15 x 7s. Dana. The 4.25 back spacing on the Magnums is about perfect.

I found that 225 70's would rub the rear front frame rails on full turns, so now use 215 70's up front. I also have 235 70's on the rear. Nice car, Jerry! Here's mine.

I have 15x7 magnums all around 8.75, 215/70 15 front 255/60 15 on back bout as much as it could fit.

I’ve concluded that this is absolutely the best color for the 67s. Love it!

Me too! R/T was originally Bronze with black vinyl top. I like it better this way! Thanks.

Jerry’s car above is gorgeous too!

I’m walking through the Pits at the Nats. A yellow 67 GTX catches my eye probably 20 cars down field and 100 yards away. It’s the friggen color.
