so i was thinking of running 195 / 60 / 14 on my 1970 valiant

anyone have any suggestions?

the "60" in the tire size is in regards to the sidewall measurement correct?

thanks

60 is the aspect ratio, the sidewall height is 60% of the width.....


A 195/60 14 is an awfully small diameter tire for a Valiant. (23.2")


I'm using 195/70 14's on my 64 and they're approximatelly the diameter as the original 13's (24.8").

I am running 195/75R14's(25.9") on the front and 235/60R14's(25.5") on the rear of my 70 Valiant. I think Dan is right they will look small in the wheel wells. Though not as bad as the 185/75R13's that came on the 69 Valiant that my brother in law has. Those really look small.

205/70R14 = 25.3" overall diameter. I run these on 14" x 5-1/2" wheels.

(185/80R13 = 24.65" overall diameter, but starting in '70, the standard wheel was 14" x 4-1/2").

You can go safely to a 205 on your 14" wheels asuming they are 4 1/2" wheels.

70 series are a little taller than 60 series.So you will have to decide on what you want.70's will fill the wheel well a little better than the 60's.Street light to street light the 60's would be a little better.Highway cruising the 70's will be a little better(lower rpm's).

I would suggest 205-70-14
This is a great all around tire.

According to the tire charts I consulted, a P185 is the widest tire you can put on a 4-1/2" wide wheel. I have seen lots of P195's shoehorned on to 4.5" wheels but you can see how the sidewall has to bend in a long ways to fit the wheel. P205's would be worse yet.

P185/75R14 is the closest match to the 6.95-14 that was stock on many of the 70's vintage A-bodies and will properly fit the 4.5" wheels.

A 205 fits a 14" by 4.5" rim perfect.No balooning,no stretching,no bending nothing.I have had these on my rims for a while now with no problems what so ever.I have asked every tire store in town including firestone & goodyear what is the widest tire you can put on a 4.5" rim(safely) and everyone of them said 205.

I'd go with the manufacturer rather than someone trying to sell you a tire on this one..................................

Mmmnot really, no. Craig's right on this one -- a 205 on a 4-1/2" rim will baloon the tread. It won't look like a cartoon-balloon tire, but your tire-to-pavement contact patch will be much smaller than it should be.

BFGoodrich, Pirelli, Sumitomo, Kumho, Bridgestone, Firestone, Yokohama, Goodyear, Dunlop, General and Michelin all say 205s need a 5" or 5-1/2" rim at minimum, depending on which specific 205 tire is involved. None of them says 4-1/2" is OK. (this is easy to look up; just hit www.tirerack.com, put in a tire size, hit "specs", and the rim size range comes right up.)
I trust the manufacturers more than I trust the trained apes at the tire store.

I've run 205's for a long time. No problems so far.

Most likely 'cause '73 Darts mostly didn't come with 4-1/2" rims.

the same manufacturer who told us to leave our 1 bubbles in with the stock exhaust manifold,there is no way this car will run with a 4 bbl and header the manufacturer says no!!,you cant do that!!!!!!!!why are you taking off grandmas hub caps and putting on bigger wheels? you cant do that,the car wont be balanced!!!!!!!!you want to do what to that head,well that will never work,those valves are to big and not to stock specs.you cant put those shocks on those are not to stock specs and forget about putting a bigger exhaust on,there is no way that will work,we have specs on this!!!!you want to put on electronic ignition HHAAA!!!!!!!well I dont see that anywhere in my manual and that isnt stock so there is no way that will work.So you are going to put a bigger radiator in for better cooling,well sorry you cant do that it is not in our manual and deffinately not to the stock specs,so that means in wont work etc....etc...etc......

Youve got to admit,if we listened to the manufactures and spec guys our cars would SUCK!!!!!!!!!!

so how do i know if i can fit a 7" rim on here?

i'm playing around with ideas for rims so bare with me!!!!

First you need to measure/find clearances and dimensions with your existing wheel/tire combo....

1. Wheel width.
2. Tire width...either measure it or goto the tire manufactures site and look it up. They'll state a width for a given rim width. You must then correct to your rim width if necessary..... adjust up or down .2" for each .5" difference in rim width. (i.e. tire manufacture lists tire as being 8.2" wide on 6" rim, you have 5.5" rim, so your width is 8")
3. Measure distance from outside of tire to inside of fender
4. Inside of tire to inside fender and/or any suspension components
5. Up front measure distance from rim to a-arms (more critical with 13" & 14" rims, I think 15" rims will clear them)
6. Measure backspacing of wheel (on backside, distance from mounting plane to outside flange) (most likely in 3.5"-4.25" range)

New rim should have about same backspacing. I'd try for about 3.75" for 14" rims, 4-4.125" for 15" rims.

Now it's time for some math..........................

1. Figure out how wide your new tire will be using the manufacters data on a 7" rim..... lets say you end up with 9.5"
2. Lets say the current tire is 6.5", so you have 3" more tire to fit under your fenders.
3. Lets say your current rim is 4.5" wide with 3.5" backspacing.
4. New rim is 7" wide with 4" backspacing
5. Figure out how far the centerline of the new rim moved out in relationship to the old rim.......
Old (4.5 + 1) / 2 - 3.5 = -.75 (Add 1 because overall rim width is about 1" greater than stated size and backspacing measures to outside)
New (7 + 1) / 2 - 4 = 0
Wheel centerline moved out .75"
6. Tire increase of 3" is 1.5" on each side of centerline, or 2.25" out, and .75" in
7. Then do you have the clearance...............

There's a difference between upgrades that work and shìt that don't fìt.
