1973 cuda stock rear widest tires without any mods?

[halle09]

i have read through a lot of other posts before i get told to look. but i cannot find anything on using your stock rear i believe 8 3/4 with the drum brakes. ive seen how to get ones with a different diff length etc but im talking about getting a rim and tire combo that can bolt right up(no mini tub etc) i have crap 14 inch craigers on now with dry rotted BFGoodrich on them i know i need to go with bigger wider rims but i am unsure of the height, width, ratio back spacing etc to get that will work. The car is a 1973 cuda i just bought. its got a worked to the bones 416 stroker i need to get some kind of traction without modding the suspension that will come later when money permits. Front wheel nd tire specs to match would be good too.

275 on a 15" rim 295 on a 17 -18 " rim with prefect backspacing will clear

I run a 275-60-15 on the back. Would not be able to go any bigger stock. Rims are Dodge steeliness with 4-1/2" backspace.

This is my exact same dilemma, I wasn't to us either a 17" or 18" diam rim, no bigger because I want some sidewall but don't want to go much past 26 or 27" O/A tire diam. I'm looking at on the rear 9" wide min, prefer 9.5-10" but I think I'm pushing it and I don't want to move anything or roll lips. I'm seeing 4.5 bs is the number. Fronts I'd go 7"-8" rim width. Tires I'd like 295's rear and 255-265 front.

If someone can confirm that combo and that they have it on a 72+ Cuda without mods that would be awesome

Also what kind of tires should be good for me? i got a 416 stroker and 355 gears. i wanna hook up and be able to take a turn without worrying about sliding out its not a drag race car at all just wanna be able to hook when i want. Its going to be a street car also where is a good place to buy the rims and tires at decent prices?

Sorry, my above post should read, I want to use 17 or 18" rear diam rims

I think 295 will need 10" wide wheel.

I also would like to know the tallest, widest tire I can put on a 17" rim on the back of a Challenger without any mods ?

Will a 17 X 9 rim fit on the back ?

I have 15 x 8" rear rims with 295 50 tires & it clears barely but with the 17 /18 " rims you have less sidewall bulge so I see no reason why a 295 on a 9" rim would not fit as long as the diff is centered & the backspacing is exact

What "series" 295 ?  a "50", "40" , "60", "70"  .......

295 is the width of the tread , so it depends how tall you want the tire to be , most use the 275  60 15 which I think looks too tall on an E body , but there is almost no other choice in 15" , I found a 275 50 for my car which is the same width but approx. 2" shorter
 Once you go into 17 " you have a lot more choice so a 295 50 may be tall enough if you go to a 45 or 40 series the tire becomes shorter , any good online tire store should have listings of the different widths & heights of the different series tires

I have 17x9, 5" BS and 275/40/17 at the back. Tires are Hankook, overall height a little shy of 26" which is close to stock height. There are about 5/8" clear either side with stock suspension location.

Front is 17x8, 4.25" BS and 245/45/17.

So according to on-line tire calculators....Comparing your 275/40/17  to a 275/45/17's I would end up with a tire the same width, but almost 1"taller ?? Does that sound right ?  I like the look of the 17" rim but not the short side-wall tire, I want to get a good width but also fill the wheel well from a side view. I plan on using 17 X 9, 5"BS rims as well.

sounds right , the series affects the height not the width so a 45 will be taller than a 40 series tire
