    Agree!! And I suppose if I *drove* the car to a shop, they might have the same idea.... *scorch* the old tires off (while taking the "long way" around to the back maintenance bay)! LOL.

      Does anyone have a profile view of a Roadrunner with 29" tall tires on the back?
      I'm thinking that maybe 255 70-15 might look too "meaty" for me.

      Perhaps 275 60-15 (28" tall) would be a good compromise (I'm at 27" now).
      Anyone running something like that with a profile pic?

      Thanks everyone!!!

      I wish they still made the 285-70-15 size , now that was a tire that needed a 15 x 10 size wheel. Looked great on the rear of a late 70's. B-body.....

      Coopers on the front and rear. If you want traction, put a set of Nitto 555R street slicks on the rear (not a good choice however if she sees rain).

        I would run the coopers 275 60 on the back and 215 70 on the front also Im pretty sure the pep boys super sport tires are the same as the Cooper cobras .

        Could be, but I couldn't put a Super Sport tire on a Mopar. I can live with Cobra, but not Super Sport.:moparsmiley:

        As far as RWL tires go, I don’t think they make Goodyear GTII’s anymore. I heard their traction was not that great either, nor are BFG radial T/A’s as good as they were 30 years ago.

        I run Mickey Thompson Sportsman S/T’s RWL tires which came out about 10 years ago. They have decent traction and look bitchin’. My next choice would be Cooper Cobras like Dennis is running. These cars look best with RWL tires in my opinion. I am running 275/60/15 rear on 8” and 215/70/15 on 7” (6” front wheel works with this tire as well).

        I have also seen many of this same car running 255/60/15 rear and 235/60/15 front but my second favorite combo is 295/50/15 rear and 245/60/15 front since the front and rear tire height are almost identical.

        I never take my car to a regular tire shop. I found a high performance suspension shop that works on old cars for the track and have always taken it there and have never been disappointed. They take exceptional care of my car.

        By the way, your vitamin C
        B-body looks exceptionally awesome!!!

          For some reason, I'm leaning toward Goodyear. I guess I remember them on the USAC stock cars that I used to watch back in the '70's. Of course, I'm probably going to stay with blackwalls, so perhaps I should rethink that.
          I might keep what I have on the front (235/60R-15), but go to 275/60R-15 on the rear (instead of the 255's I have now). Is there any concern with the extra 20mm width on the rim? I have Magnum wheels, but I don't know the width (no way to determine that unless I take the tire off & measure the rim?).

          No problem with 275/60/15 if it’s an 8” wheel. If it’s 7” wheel it’s not recommended. Not sure how to know wheel width for sure without removal. If you do remove it, remember the advertised wheel width is from inside lip to inside lip. A 1/2” more on each side past the lip is the general rule. So an 8” wheel will measure 9” total overall so the tire bead can seal.

            Thanks!!

            What would be acheived by going narrower in the front? I've got 235's in the front & you've got 215's.

            If they made 15” diameter tires that were 235mm wide and 27” tall I would love to run them. Since my 275/60/15 tires are 28” tall, I went with 27” tall 215/70/15 in front so my rake wasn’t too high while keeping the front fender gap to top of the tire to a minimum. If I was not so set on the wide 275’s I would actually be better off to stick with 27” tall 255/60/15 in the rear and the 26” tall 235/60/15 up front like you’ve got. The car will drive more balanced. I tried 275/60/15 rear and 235/60/15 front and thought the rears made the front 235’s look too small.

            I think our cars look best with 15’s, but if for some reason you were to consider 17” diameter, there are tons more options to get the same height tires on all 4 corners while still keeping wide meats all around. This is tough to do with the 15” offerings.

            The lighting is not the same as your car’s photo but here are vitamin C cars with RWL tires I found online to give you an idea for your car. I posted your car photo as well so you could view them together.

            Man looking at them side by side I like your car best the way it is with those black walls and 255’s out back. I think you should leave it alone:)

            I too have been using the Cooper Cobras for a few years. Mostly because they are one of the few Manufacturers of the 14" & 15" tires. I don't think Goodyear and BFG are into these sizes any longer (at least they are not available in my neck of the woods)
            I always remove the wheels and haul them in for new tires since I don't care to have my cars exposed to the shops and their employees any more than I have to. Matter of fact, I just removed the wheels from my 65 Sport Fury yesterday and took them in for some new 225-70 Coopers. I don't put a lot of miles on them and they looked good but I felt a little wiggle when I drove the car last week-end. After inspecting them, (Cooper Cobras) I found two tires with a belt separation and was glad I didn't take the car out at highway speeds. When I checked the dates on them I was amazed to find 2603 on them. Time gets away and I hadn't realized they were 16 years old! I thought I stayed on top of the maintenance issues better than that. Guess I was wrong.
            I always have them turn the white letters to the inside because I prefer the black wall. I use the excuse that if they want me to advertise for them, I require a monthly fee.

              I get my Coopers from tirecrawler in Downey, California. Free shipping and drop at the shop. The hottie on the phone always checks the build date at the warehouse. My last Goodyears on a modern car were the Assurance model. Egg shaped miserable shake. No more Goodyears. I ran Eagles for years.

                Hmm, maybe I should stick with what I've got then? Do you have any photos of that setup (275/60 rear & 235/60 front)? I was actually thinking that I might like another inch in the back, but I don't want something that's going to look odd (you say the 275/60's made the 235/60's look small). You can see my first post here with a pic of what I've got.... it's a good stance, but I was wondering how an extra inch in the back might look.

                Rick, i cant help with a rr profile shot, but here is a lousy shot of my 62 with 255/70-15 t/a radials on a 8" ramcharger rim, 29" tall, 8" on the ground.
                I would have liked wider (275/70) but the backspace prohibited that. The height is essential, 62 has a ridiculously long wheelwell opening, 36" that needs to be filled to look right.
                I think your runner will look best with the wheelwell filled, height wise, then as much width as you can get on your wheel of choice. 28"slicks looked great on mine.
