Tire size

Postby Greybeard » Sun May 29, 2016 12:56 pm

With unaltered wheel wells, how much tire can you put under the back of a Vega with proper offset? Was going to put 235/60/15 Mickey's under mine and was wondering how much I was leaving on the table.

Length or width of rear end may play some part in selecting wheel/offset/tire dimensions.
54" drum to drum
I think max wheel and tire combo would be
235/60/15
15x8 with 4 1/4 offset wheel..

I'm planning on running Pro-Trac 235/60/15
15x8 with 4 1/4 offset..
Not much room let to spare

Tire section width may also play a little into your selection also...
Pro-Trac vs M&H tire section width are totally different even in a 235/60/15

Not sure about M/T

I tried a bunch of different wheel and tire combos on the rear when I had a Vega on the street. I agree that the 235/60/15 is the biggest that will fit INSIDE the rear wheel well. If you like the "gasser" look (I personally don't, but many on here appear to), I've seen much bigger.

Well, that answers that. I don't care for the '60s gasser look myself. In the '60s there was a town 35 miles from where I lived. It seemed like everyone had put airbags or shocks on their cars, and put as much air in them as they could stand. The back ends up would be up in the air so far you'd swear they could unhook their fuel pumps and gravity feed those suckers. Anson slotted mags sticking 6-8" past the bodies. There are, to this day, at least three of those suckers still running around down there. One would have thought they had all been wheel hopped to death by now.

Found an ancient pic showing the 235/60/15 rears and 195/60/15 fronts on 8" & 7" Rallys. It was almost 30 years ago, but I think I went down to a 225 in the back to get the car a bit lower.

I like that 225 70 15 but wondered if a 225 60 16 will work?...or even a 215 55 or 65 16 ?....I'm sure the rear end offers a lot of options but the front end is really the main concern...I still use the original rotors and they've been upgraded to 4.5 on 5 bolt pattern so I'll use the stock calipers but it's the offset and size we need to experiment with...I'd like a 15 on the front..Fred, was it you suggested to us a 6 in. rim with a zero offset??
