Biggest tire on a Fox body?

[Lane]

Without sticking out of course... What size tire and wheel, with what backspacing of wheels you guys(or have seen) running? Does it take massaging of the wheel wells? Mini tubs a good idea? M-tubs sure would be easy to do right now with the car stripped. I don't need or want 31x14's or anything - just would like to know what fits well in a 28" tall slick and 325-50 DR.

Andrew - didn't we mount 28x10's or 10.5's for you?

Manny?

Anyone?

Thanks! :)

I've got 28 x 10.5's on a 5.5" BS 15x8 weld draglite. I had to hammer on the wheel well, roll the fender, and cut a bit of the front and back ground effects. You could use a 6.5" Bs on a 15x10" draglite.

15x10 with 6.5" BS?

Thanks guys!

[302_plus_a_few]

I had a 15x10 wheel (6.5" BS) with a Goodyear 28x11 slick on my old car. I had to use a 1/4" spacer as well. It was tight in there. Lots of wheel well beating.

Looks good Kirk!

I think the section width on those Goodyear 11's is about 12.5". Big tire.

I'm thinking of mini-tubbing this car. :) A buddy of mine just did his Nova and said it was very easy... We'll see.

It would make fitting tires a lot easier!

The best one I've ever seen done was a guy that cut the stock spring percchs out and welded a couple of Chassis engineering per-formed frame rails to the inside of the stock frame rails and then installed ladder bars. It was a home brew setup and it was on a coupe. He had a 30x12 Goodyear slick on it.

My dad has c/o on his GR40, and he has lots of room from where the spring used to be... because the spring is about 1/3 the size...

LOL - yeah, maybe I'll take a look at that spring perch! THAT might cause some problems...

[GT40MkI]

Honestly, a 28x10.5 (or in my case a 28x12.5 et street, virtually the same size tire..is about all you wanna do on a stock style suspension.

Mine are the same 15x10 with 6.5", and I have a 5/16" spacer on each wheel just in case.

ALso going from a 15x8 w 5.5 to a 15x10 with 6.5/spacer on the exact same tires knocked off about half a tenth consistently on the 60 foot times...

I run 15 x 9 Alumastars with a 6 3/8 backspace and 28 x 12.5 ET Streets and it's real tight!!! But it looks good:)

[mikeb]

I still have those 15x10 draglites with 5.5 BS (and also a spacer that I can't remember how thick it is) if you'd like to try them.

I'd make ya a good deal on them :D

[spankustang]

how big is a 325 50 15 drag radial??? Is it like a 28x10.5 or is it bigger

[GT40MkI]

Mathematically a 325/50-15 should be 27.25"x12.25"...however given that its a radial I'd figure the tread would wrap a bit and be closer to a 28x10.5-11"

Also, with a radial type sidewall you should be fine....I'm looking to move to drag radial too probably...so I'll let ya know/you let me know...

Is 12.25 the treadwidth or from sidewall to sidewall???

Technically speaking, the number 325 is the tread width in mm. Conversion to inches is 26.5mm/inch and you get ~12.26xxxx

The the 50 means that half of the tread width (50%) will be the sidewall..

From the MickeyThompsontires.com site:
3757R P325/50R15 (28x13.50R15)
3762R P295/65R15 (30x12.50R15)
3763R P315/60R15 (30x13.50R15)

And from Summit(BFG 325/50-15):
Specifications:
* Tire size: P325/50R-15
* Overall diameter: 27.9 in.
* Section width: 13 in.
* Tread width: 10.5 in.
* Recommended rim width: 9 in. to 12 in.
* Load rating: 2,447 lbs. at 44 psi

Looks like its going to be fun making em fit-I'll probably end up with a bit more (7/16") spacer and a big hammer inside the wheel well...if you get em first let me know how it works out... ;)

I'll post pics if I happen to run across a set...at $320-350/pair I'm not going to be too keen on any rubbing going on back there...

[GT40MkI]

While we're on the topic...anyone know when the MT Drag Rad's will be available?

[spankustang]

I saw them on TV but haven't heard when they'll be out!!:(

At SEMA, they told me the 275-60r15's would be out in January and the other sizes would follow in the next few months...

[spankustang]

what's the spec's on a 275 60 15???

[GT40MkI]

3754R P275/60R15 (28x11.50R15)

According to MT again...

My old BFG 275/60s were not as tall tho, closer to a 27x10

15 by 10 6.5 BS with 1/4 inch spacer, fits perfect

Yup, here's mine with that setup.
