Need tire help for 20x12 wheels

[Bowtie468]

I'm in the process of ordering new wheels for the '68 and would prefer to run 20x12's in the rear instead of 20x10's. The problem is that i'm having trouble finding tires for the 12"width. I'd like to keep the tire o.d. at 29.5" and not go any taller. I've seen 295/40R20 tires on 12" wheels but they looked really stretched out. They look real sweet on a 10" wheel. If i have to, i'll just go with the 10" but would much prefer the 12" Any input is surely appreciated.

315/35-20's will fit the width but are a little short of your optimum 29.5" goal (28.68"). You'll need to make a choice on what's more important, the height or width?

I did come across that size and really didnt give it a second thought because of the height. Hmmmm.. let me add to the story a lil bit. Im planning on 20" rear/18"front combination. The tires i am looking at are 29.3" and 27.3" o.d. This 2" difference would keep my sidewall height the same, front to rear, and also allow me to tuck the wheels up in the fenderwells the same amount and still have a nice rake to the front.

Wonder how much different it would look with a 28.68" tire. I guess i'll have to sleep on this one!!!!


....WOW !! Prices go thru the roof on a 315/35 !!!!

A 245/45 has the same sidewall height as the 315/35. As for cost.... you gotta pay to play.

335/30/20 but that aint gonna fit stock tubs and they are high. Let me see these when you get them on there since I am in the same boat. I am going with the 335/30/20's on mine as bad as I hate to.

Something to keep in mind when calculating for fitment is "advertised" height vs "actual" height. What they say on the sidewall doesn't always mean it will measure out that way. I have seen many times that tires were shorter or taller than "advertised" height/width.
