Wondering if anyone has tried a 245/40/17 on a stock rear end on a 65 sedan. The inlet non stock item is a disc brake kit on the rear. TIA!

Here’s a 255/45/17. A 245/40/17 shouldn’t cause you too much trouble with the right offset.

What size wheel? Did you have to modify anything at all? I’d love to stuff a 255 under there if I can!

The wheel is a 17x8 offset 20 BMW wheel. There are no modifications done to the car. It is a completely stock rear suspension and sheet metal. It is very close inside and out but it is clear.. I don’t think you could squeeze any more tire in there.. A 245/45 would leave a little more breathing room though..

finding wheels

Ok gurus, seems I am having a hell of a time finding much to choose from for my 65. Looking for a 15x7 with at least 4.5 backspace. currently have a 4" backspace in the rear and any load in the back and the sidewall rubs in the fender. Id rather stay with 15's since I just got new tires. went from a 235/60/15 to a 225 hoping it would help and well, here I am. Stock rear soon to upgrade with CBR leafs as soon as I get the fitment taken care of.
Is there really this little choice in this size?? :(

With a 15x7 you’re going to want 4.5-4.75” of backspace to put bigger tires in the rear.. if you look umber the back of the car you will see a pretty decent amount on space between the tire and the leaf spring.. This is where you can exploit this unused territory and fill it with rubber..

KDee - those Rocket Rims are 7inch 15's very light and are 4.250 back space and should work fine as I use them on my 1962 with a P235/60/15 Tire. Even though my rear end is a Strange ford 9 they made it to the exact spec size as the original 1962 rear end even the perches are in stock positions.

I am one of the smallest tires at the drag strip and it sucks because with out cutting in tubs I can not go any taller than the 26.1.

I would have to say that is one of the worst draw backs of the Car compared to newer production cars or tubed cars like mine.

I also lowered the rear 2 inches the only safe way you can! you can see my lowing the rear of a 1962 Chevy II here: http://www.billingpros.com/ChevyII.html

I know the subject has been beat to death and 15x7 with 4.5" bs is ideal, but has anybody else here had any success running a 15x7 with a 4.25" backspace?

I found some wheels that I REALLY like for the rears. The 15x7 is only available with 4.25" bs.

So we bit the bullet and are doing a DSE mini tub on the 65 Sedan. If I want to run a 17 by 10 with a 275/40/17, how much narrower does the housing need to be from stock or what backspacing have folks used? Also I will be using a CBR tri-4 link. TIA!!

In the simplest of ways, re-drill the rotors to a 5 lug pattern. However, there are then many considerations. Redrilling to many of those patterns (ie. 5X4.75) requires welding a hole closed then redrilling. There is also will the drums fit? Even in this thread, A lot of thought has been put into Wheel offsets: and are you going to run different offsets on front and back? Point is - mistakes can get expensive when you are purchasing wheels and tires.

Sorry for the same pics cross posted on a few different threads, but here's some 205/70 14's and 185/65 14's on a '64. The wheels have 3.375 in backspacing. Plenty of room! Sadly - I found out they no longer make the BFG raised white letter radial in 195/65 14, which was my original choice up front (with 205 rear).

Taking Powerglide in for rebuild and need to make a decision on wheels. Currently plan on going with 225 60 15 on 15×7 with 4.5 backspace, but would like to go bigger heigth/width wise on rear. Suspension on my 63 Nova is stock, except for 2" drop spindles and Right stuff 4 wheel disc brake conversion. I've read that 235s, 245s and 255s (all 60×15) will fit on the rear, but no mention of backspacing mentioned that I can remember. Any input appreciated.

For the rear of my 64 I had some 15x8 w/5.25” of backspace. I have 225/50/15s on it currently but I feel 235/60/15 could work. I have yet to try that size. If you want to run 15x7 I would suggest 4.75” of backspace as the outer sidewall will be closer to the outer wheel houses.. I’ve had 225/60/15 on 15x7 w/4.25” backspace and they rubbed frequently.. Give yourself a 1/2 inch and go 4.75” of backspace..

The black wheels are 15x7 all around. The silver wheels are 15x7 front and 15x8 rear.

I ignored good advice and am running 15x7" with 4.25" bs (off the shelf size) 62 Series Wheel Vintiques with 185/60's in front and 205/65s in back. I had a little bit of rubbing on the front fender on rare occasion but I persuaded it with a mallet and now its fine. I have 69' style discs so they're pushed out a bit from stock, not sure where the rear end came from (I think a 63 SS?). but no trouble there. Cars lowered a bit with cut coils and old leaf springs.
That said, any larger tires and I'd have lots more issues. This is the look I had to have, at a price I could afford and a little bit rubbing on odd occasions doesn't bother me.

Hi. I have a 1965 Nova with 14" wheels with a 4 3/4" bolt pattern. I currently have 185/70//R14 tires mounted on the standard 14" steel wheels. I believe I have a standard rear end on the car. Will these wheels mount directly on my car with no problems? Also, will my existing tires mount to these wheels with no problems? When it says 3.75 backspacing do I need to buy something sort of back spacer or is that part of the wheel? 14x6 Chevy Rallye | 5x4 3/4. Thanks! Gil

You should be fine with the 185/70/14 on the 14x6 wheels. The backspacing is the dimension from the back side of the wheel mounting surface to the inboard (towards the leaf spring) outer wheel lip where the tire bead seats.
