widest tire for 6" rim

[74fldart]

hi fellas, im wanting a wider tire for a set of 6" cragars i have for my 74 dart. now it has 195s on. i want to go to a 225 or 235 /60 / 14. will a 235 go on a 6" rim?

Yes, it will fit perfect! The biggest radial tire they make for a 14 inch wheel is a 245/60 R14, that will also fit.

It will fit and I have run a 245-60-14 on them but with that size you are pulling the side wall in. I have 225-70-14s on the back of mt Dart, they are a bit wide for a 6" rims also. a 215-70-14 is probably the biggest size that is recommended by the tire manufactures for a 6" rim.

I have the same or a similar question regarding my 1967 Barracuda Notchback.

I currently have 195 70-14 on 6" front and 225 60-14 on 7" rear.
I was thinking of moving the 225's to the 6" wheels up front and buying a set of 245 for the rear. Will this work?

According to this chart:

It looks possible, but the max width for both wheel sizes. Has anyone successfully done this? I also question how well the 225's will fit in the front.
Any insight would be great.

The 225/60-14s ought to fit fine on the front. I have 235/60-15s on the front. It is more than 3" larger in diameter than the 225/60-14. It is close, but nothing rubs.

I guess the only way to tell is to put one of the 225's on one of the 6" wheels. If I have time this week I'll try one. I wonder how bad the sidewalls are going to bulge?

 

[70Valiant]

I have 235/60R14's on the 14X6 slots on the back. The center of the tread wears out FAST if you have the tires fully inflated (35psi on the BFG's that were on there)

 

[67Baccaruda]

I mounted a 225/60-14 on a 14x6 wheel, at 36 psig the outer sidewall looked good and the tread seemed fairly flat. The inside side wall did bulge slightly. I think I'm going to go with this on the front. I plan on getting a set of 245/60-14 for the 14x7 rear wheels. Any comments on this setup???

215 is going to be the widest recommended by the tire manufacturer's, as stated above. I wouldn't go over 225 with a 6" rim, your tire life and handling will drop off too much after that for it to be worth it...

 

[daredevil]

ive ran tires on small rims and small tires on big rims and never had problems either way.maybe not an autocross set up but 245s on a 6 or 7 isnt a problem

I must be missing where it is stated above.

P225/70R14 Rim Width Range (inches) 6 - 7.5

I know this seems to be pushing it. If I can find where BFG states 215 is the largest then I will buy a set of 215's

When I went shopping for tires for the Barracuda back in 2000 the minimum recomend rim width by Goodyear for these 235/60-14 tires was 6". The ralleys are 14x6" and the tread has 50k miles. I now have 15" rims with much bigger tires on the rear

Adam R already mentioned it... But I think we were both just talking from past experience and not a specific manufacturer's spec.

Keep in mind that's a 70 series tire. Since the series gives sidewall as the % of width going to a 225 wide 70 series will give you a taller tire than what was original, a 225/70/14 will give you a 26.4" tall wheel. The higher the series the more sidewall, so you end up being able to run a wider tire because the sidewall has more flex (not necessarily a good thing). I did notice they also list a 225 for a 6" in the 60 series, which is fairly generous for a manufacturer recommendation, but I guess I'm still getting used to running 14 and 15" rims with a high series tire (my old srt4 ran 17" rimes with 45 series tires, biggest for a 6" on that is 215).

Also each manufacturer is different. If you want a set of BFG's, I'd go by their recommendations. You can usually run the next size above those recommendations without too many ill effects, but I wouldn't go higher than that.

I copied the wrong line last night.

P225/60R14 Rim Width Range (inches) 6 - 8

Not: P225/70R14 Rim Width Range (inches) 6 - 7.5

Thanks for picking up on that. I am using 225/60-14's
