    Tire suggestions for a Hawk GT 62

    Upon closer inspection of the tires of my recently purchased Hawk GT 62, I found out that I will need 4 new tires because those that are on the car suffer from dry rot and are bad.

    The owners manual states that tire size is 6.7 X 15. A quick search online for conversion gave 205/75R15 and 215/70R15. I do not know what size I should buy.

    Also, there is a choice between bias or radial.

    Then I d like to put white wall tires. Then there are inserts available.

    I don't want these tires to cost me an arm and a leg. What are you using for tires? Any suggestions?

    I had mounted 215/70/R15 Dunlop blackwalls on my 62 GT, just because that was what I found on sale at the time I needed them. At the same time, I got some Ford Crown Vic steel wheels to put them on. No clearance issues.

    For what its worth, I'm very happy with my 185/15 Retro Classic. Moreover, they are not expensive. Dunno if you can find them in Canada, though.
    Nice week-end to all.

    The stock factory wheels are not recomended for use with radial tires. They tend to crack. Use a later wheel designed for radial tires.

    You got a good deal on your portawalls. How long ago you bought them? The crown Victoria rims were a good deal. I bought 4 used one at the scrapyard for 20$ CDN a piece. You mentioned the size as being 15 inchesby 6.5. I reckon that 6.5 inches is the width of the rim, right? Bolt pattern is 5 X 4.5 ? Most probably they will be black and I wonder if I should not paint them white. Car is off white and I will order white portawalls. Overkill?

    Ford Wimbledon White is a pretty close match for the off white the Stude wheels were painted in 62.

    They should be 215/75 R15. That's the closest to the original tire's overall diameter and as skinny as can be bought. 205/75 R15 ore OK, too.

    The original tires were 85 aspect ratio, so the closest is 75 aspect ratio. I would not pout 70 aspect ratio tires on an old car.

    All of these tires are too wide for the original 4.5" wide wheels. 6" wheels are preferred.

    Keep in mind also, even though 1962 was the Last Year for Wide Whitewall Tires, the 1963 to 1966 Design Narrow White Walls look GREAT and do NOT have to be bought from a "Classic Tire Co." for BIG BUCKS!

    Cooper Trendsetter Tires:
    P205/75R15 97S 440 A B STD WSW 5 - 7 5.5 8 26.97 5.12 20 1598 10.5

    You REALLY do NOT want to have Portawalls grinding and flopping on your sidewalls every time the Radial Tire sidewall flexes as it flattens on the bottom and becomes round everywhere else! They WILL Kill the tires!

    Yes 6.5" wide, standard Ford /chrysler/ Studebaker and many others bolt pattern 5 on 4.5" (114.3mm).
    My wheels were black, I stripped and painted them with an "Ivory" paint from Ace Hardware. I can't remember if it was their store brand or Dupont Krylon. I tries several different paints this matched the original wheels perfect. Ford Wimbleton White is too yellow.

    I've never had any problems with Port-o-walls on any tire either bias or radial and have had them on a few cars. given the option I'd rather have actual white wall tires but they are pricey. The tires Rich mentioned arent too bad but they only com with a .75" white wall. https://www.summitracing.com/parts/c...BoCDHIQAvD_BwE

    The 215-70-15 on the 6.5" wid wheels fit perfect under the GT like they are what it should have come from the factory with.

    I just bought off of the Walmart website, four P205/70R-15 Mastercraft tires. The photo on the website shows a white letter tire, but thats not what arrived. Mine are all black. I just needed a cheap tire to get the ole girl on the road. I am very happy with them so far. https://www.walmart.com/ip/Mastercra...70R15/47406030 Side Note*** I am running a late 70's Ford aluminum wheel.

    Would 205/75/15 tires fit on these crown victoria rims?

    Of course they would, they are made for P205X75R15, P215X70R15 etc. modern RADIAL Tires.

    However, 205's will fit better if you do not get crazy with the width.
    Use EARLIER Ford 5 1/2, or 6 Inch Wheels not too Late; 7 Inch ones!

    Rear Wheel Drive Chrysler Wheels also work fine, both with the Larger 13/16" Wrench Size Lug Nuts not 3/4" Stude. though.

    A Rare/Oddball Profile like that would make it Hard to find proper Whitewalls and smaller sizes like P205, plus fewer Brand and Tire Model choices, not to mention failed tire replacement possibilities in a few years.

    This is a 235-55-17 on a 7.5" wide wheel with 5.25" of backspace. It's the same diameter as a 205-75-15 but 1.18" wider.

    A 15" tire with a 65 aspect ratio would need to be at least a 235 in order for the diameter to even be near stock and keep the speedo somewhere near close to correct.

    If you are staying with 15", I have successfully run P235/70r15's (sadly no whitewalls) on my '63 GT for over 35 years and they fit a 7" wide wheel perfectly and I think suit the car. I always feel that GT's in particular should have a decent size of sidewall to look and handle right. <O.D= 28.0" Section Width= 9.4 on a 7" rim width Load Index= 1896 lbs>. If you were to run a 65 series the only large popular size is 215/65r15, the original optional Camaro/Firebird fitment which is only 26" tall and your load index drops to 1510 lbs. To each their own.

    I have been successful in using Ford Ranger 15" standard steel wheels and the Ford lug nuts.
    I prefer the 215 75R 15 Cooper or Hankook whitewall tire over the 205's due to the diameter being closer to the original tires. Tires are reasonably priced, look good and handle well. Cooper's are even made in the good ole USA.
    The other advantage for me is that when the tires get a few years on the Studebaker, I can put wheels and all onto my trusty 2001 Ford Ranger and run some rubber off the tires before they go bad by age.
    A set of used Ranger wheels can usually be found for less then $100. Just don't get the optional spoke wheels because the wheel lip won't accept a wheel disc.
    That's my opinion, and I'm sticking with it.......................

    You can keep your Studebaker rims and get a set of these:



    And if you figure you will replace five radial tires every six years, the price of these type of tires is probably cheaper. Tire shown was bought in 2000, has no weathering cracks, and the whitewall is still in really good shape...

    Are you using Ford or original Studebaker lug nuts?

    FORD .....kept them when I took the wheels off the Crown Vic at the wrecker.

    We've got the same wheels and tires ,(no white wall) on our '53 coupe too, they fit perfect on both. Look better on the GT though, must be the white wall.

    Are your tires radial or bias ply?
    What size and how much did they cost?
    They would look good on my 50 L/C

    OK, there are a lot of opinions about size. If you really want to match the original 6.70x15 bias ply tires that came on Hawks, Avantis, V-8 convertibles and Wagonaires, 215x75x15 radials are virtually the same diameter as the original tires. 205x75x15 radials were a good match for cars that came with 6.40 and 6.50x15 bias ply tires. In the attached picture the tires from the right are 195x15 radial (obsolete size), 205x75x15 radial, 215x75x15 radial and 6.70x15 bias ply.

    When I had to replace the 215x75x15 Firestone whitewall radials on my '64 Wagonaire due to a severely damaged tire I couldn't match the Firestones so I called my Cooper dealer and asked for a set of 215x75x15 whitewalls I had them the next morning. Thinking they could also be new, but old stock I looked at the tire date codes and they were only three months old. I have 215x75x15 Hankook whitewalls on my Avanti, but apparently they don't make whitewalls in that size anymore. With the correct tire size and a 3.07 rear end with the correct speedometer pinion, my odometer is only 1/10th mile off in a 10-mile stretch as measured by Interstate mile markers.

    MontrealHawkGT62,
    I should have added to my post#17, I also have my GT equipped with 3:73 Posi so I need a tall sidewall to keep the revs sane on the highway. If I recall correctly it puts me approximately at 3000 RPM just over 60 MPH which is no problem as my non-stock motor willingly revs to 7000 RPM.

    They are BF Goodrich bias ply, 6.70x15s. I think they run @ $175 for Universal's version of same, but white wall is 2 1/4 - little thin for a Land Cruiser - https://www.universaltire.com/670-15...whitewall.html.

    The LC had a larger tire though, I am thinking it might be a 7.10 (or even larger?). Good luck.

    I'm already starting to think I should have spent more money for some nice wide whitewall tires.
    I guess I can save up for wide whites and run these radials on my 1999 Olds.

    As Roy pointed out, you would want the 7.60X15 - again Universal has a period correct tire for $188... I have gotten rid of all my radial tires on Studebakers and really enjoy the look and ride. New OEM tires for my 2009 F150 run $195 each on Tirerack and need to be replaced when they turn 6 years old - not when they were mounted and hit the road... Good luck.

    Alot of R75's suggested here, trying to copy stock----thats fine but .....to go with a Little shorter tire, try sizes with R65 and R70
    you can get same widths---- just a ever so slightly short tire---- vs , the Tall look

    WOW pricey tires. Firestones for my Tundra 4x4 only run $80. 18 bucks more at Tire rack. I don't remember the last time I actually wore a tire out though. Since the forced change in tire rubber compound they fall apart long before wearing out.

    One issue that might not affect everyone. I e-mailed Cooper. They only make 0.75" wide whitewalls in 215R/75-15. They don't have the wider whites that are proper to the 1962.

    The stock factory wheels are not recomended for use with radial tires. They tend to crack. Use a later wheel designed for radial tires.
    Do you think these Crown Victoria rims would fit if ever I do a front disc brake conversion? Also do you happen to know what is the offset on the original rims?

    Just today I bought a set of 4 Coker classic radial wide whitewall tires for my 61 Hawk (to go with my brand new steel T-Bow rims). A little over $900 with shipping to Boston. They better look real nice for that price!

    They fit around the 2004 Mustang disk brakes I put on the car.

    I just bought a set of Hankook 215/75 15 to fit on my mid-80's Jeep wheels on eBay for $220 for 4 free delivery with a 4th of July gift card of $75. $145 for a set of new tires and was delivered in 2 days.

    Off topic, but can you elaborate on the disc brake conversion?
