    Tire fitment is always tricky, I run a 17x7 245./45/17 with 4.5" backspacing on front and 17x8 275/40/17 4.5' backspacing on my 67 mustang convertible and it fits beautifully. Best of luck love watching you work things out..

    Nice, I mounted Nitto 275/60R15 drag radials with 5.5 back spacing on my Coupe 68. No fender rolls about an inch from the leaf springs.

      Yeah, it's tough to compare the fitment of the '67+ Mustangs to the '64-'66 Mustangs since the early cars were so much narrower. :)

    I actually narrowed my rear end to fit 245-R60-15 in the rear with Torque Thrusts. No rubbing on fenders, no rolling needed and no rubbing against leaf springs. Have about 3/4 inch clearance to fenders and to leaf spring. Also have 1" lowering blocks installed.

  • @BrianGoldsworthy-x7g
    @BrianGoldsworthy-x7g หลายเดือนก่อน

    Andy, Your coverage of the topic is great but there is something else to be considered. In an aggressive turn the sidewall will 'squirm' to the point where you lose a little more clearance. It is mainly the outside wheel - (IE. the right wheels on a left hand turn and of course the left hand wheel on a right hand turn) It will vary depending on sidewall height, rubber compound etc - but you may get some scrub on aggressive corners. I have the same car as you and only run 225/60/15s on a 15x7 steelies but I am considering wider after watching this

    • @AndyKruseChannel
      @AndyKruseChannel  หลายเดือนก่อน

      Thanks for the heads up. Under extreme cornering, the bottom of the outside tire will see increased loading causing it to roll under and deform, but that deformity returns to "normal" as the tire rotates and the top of the tire looks and acts like the car is standing still. However, under cornering, one needs to be aware of where the outside tire will be with respect to the fender as the suspension compresses and the tire begins to fit up inside the fender. Also, the with wider tires (and depending on the backspacing), the inside edge of the front and back of the tire may touch components of the car. This is seen in my video where the frame lip has been notched where a tire could touch if the tire was wide enough.
      You are correct, it's more complicated than just sticking wide tires under the fenders, so I am keeping those kinds of potential fitment issues high on the list as I narrow down the wheel size, backspacing, and tire size. :)

    • @AndyKruseChannel
      @AndyKruseChannel  หลายเดือนก่อน +1

      The wheel size doesn't affect how the tires fit. It affects the look and how the car handles, but for the exercise I was trying to show in this video, it's the width that I was trying to find. A 255 wide 17" tire is the same width as a 255 wide 15" tire. :)

    • @sera_synod
      @sera_synod หลายเดือนก่อน

      @ I wasn’t sure whether sidewall deformation played a role. The tighter fit of the tire to a taller wheel might mean the tire shifts around less under load in a corner? Might be something I need to research

  • @Bukes66

    I ran across the issue where I fit 245s in the rear, but the leaf springs deflected and cause some rub on the fender lip. I’m going to upgrade to rollerized leaf spring hangers. Either that or a track bar.

    • @AndyKruseChannel

    Might want to try Team III Wheels/ET Mags, if you need custom backspacing. I bought a set of mini lite style 17x8s with custom backspacing from them and they were pretty good to deal with. Not cheap, but not too expensive considering the quality and a custom wheel.

    255/40r17 on a 17x9 (+4.5 inch bs) would mean less tire bulge which means more inside tire sidewall clearance including to fit a 275(rated on a 9.5) in the future.

    • @AndyKruseChannel
      @AndyKruseChannel  หลายเดือนก่อน +2

      Yeah, but I'm also trying to have my cake and eat it too. I don't care for the look where a tire is stretching out to meet the rim of the wheel, so that 255/40 might not be where I want to be.

    My 67 has lowering springs front and rear. 245/245/17 rubbed the front fender where you were close so I had to go to a 225/40. On the back those 245/45 scraped really bad so I went to 235/40. Still not much better but it’s expensive to experiment. My wheels are 4.5 BS I think and wish I had gone with 5”. I’m always curious about the Meier Racing rear leafs that claim they can run 295s in the rear. I guess an expensive experiment if you want to try that. That’s what I may do since it’s still cheaper than a 4-link or IRS.

There no weight on the tire, there is no back spacing. Wait to winter, put the breaks and find the rims that give best handing without a lot of cutting.

      the disadvantage of lower profile is obviously that not all road surfaces are created nor keep smooth, that said most 1965 fastback race cars use a 245 45 16 if the class allows larger than a 15” rim, at some point it’s more difficult to increase contact patch by increasing rim size only to reduce tire profile, you end up with the same contact patch, that said running a smaller rim diameter reduces sprung weight, and lowers the cars center of gravity. Honestly I would rather be a bit lower in exchange for brake size, not really giving up
      a whole lot 16” wheels are probably ideal handling wise for mostly stock configurations.

    I sense fender flairs in your future lol
    18" wheel will give you more options for a tire, possibly even slightly more economical. I prefer 16" wheels for weight considerations, but tire sizes and getting limited along with 17" wheels.
    Trying to maintain a squared setup (same size, all 4 corners) is going to be the most limiting aspect. May as well embrace the stock max staggered setup with 225 on the front and 245 on the rear. Also be honest about how the car is going to spend 80% of it's time running..... race track? Yes, max out rubber contact patch on the road. Daily driver / parade car? 1-2 sizes wider than stock should be enough and keep the main experience enjoyable.

      @@AndyKruseChannel About the only thing on my car that I have never had off or replaced is the leaf springs. Would you suggest changing to the 3 link like you or stick with new springs?

      @@1965copester New springs won't provide the stability that a 3-link provides. I'd do both, but the 3-link (or Panhard Bar) will generate more smiles than new leaf springs. New Leafs will compliment how the car can be driven once you install that Panhard Bar. :)
