Opinions??

[Rixster]

Can't make up my mind & thought i would seek some opinions. I have a 69 GS400 & i'm thinking BF Goodrich Radial T/A's, 235/60/15 all the way around, sitting on 15x8 rallyes from Wheel Vintiques. I don't want to lose much speedo calibration, but i want a nice looking stance. Also, hard to rotate them if i do bigger in the back & smaller in the front. I haven't bought anything yet, so should i go 15x8 or 15x7? Maybe some pics, along with tire & wheel info will help me make up my mind?:Do No:

Thanks!

For that size tire, i don't see any reason to spend the extra $ for 15 x 8s

I agree... if it were 255/x/15 then maybe...

[Rixster]

That's what i'm not sure about. For the 15x7's, i was thinking the 235/60/15. Then i thought i might want a bigger tire later, like the 255 or 275, so i thought the way to go would be 15x8. I'm thinking it was a difference of $10.00 a wheel. Am i thinking right on the size of the tire itself for normal street use & maybe a strip run here & there? How much will my speedo calibration be off if i jump to 255x15?

Thanks

Don't worry about your speedo. Swapping the gears in the tranny is a piece of cake. Gears are only about $5 at most GM dealerships.

I say go for 15 X 8 in the rear, and then 15 X 7 in the front.

thye BFG's are a hard tire so I don't think you will really have to worry about rotating them too much.

The wider tires in the rear are a bit better looking I say.
just one more thing, make sure you get a small back spacing like under 5 inches. Else the skinny rim tires get sucked way in and that probably won't look good either.

I always just lived with no speedometer/inaccurate speedometer whenever there was an issue with them.

I have smaller O/D tires on the Skylark now (not by choice... but they look ebtter and are wider than the stock steel rims/tires) than stock... which isn't really as dangerous and larger O/D (small will make the speedo read fast, large will make it read slow) either way, it will probably only be a 5-7mph difference... I know the O/D of my original wheels/tires is up around 27"... and a 255/60/15 tire is 27" ... so I agree with 70 gsconvert ... speedo gears aren't expensive, or can you just choose to live with it.

The 255's would look better, IMO :grin:

And about the small backspacing, I agree... my car is proof. Guy that had the car before me bought the rims, and they are tucked WAAAAAAAAAAAY in... at least in the back.

So, what would i ask for as far as speedo gear if i were to go 15x8 with 255x60x15 in the back. From what i'm gathering here, most people think 15x7 with 235x60x15 in the front, & 15x8 with 255x60x15 in the back. That's what i've been thinking too. Rear spacing would be 4" for the front wheels & 4.5" for the back wheels. Any opinions on particular type of wheel to use? I don't necessarily want to put rallye's on it if there is another wheel out there that really stands out for the 69 body style. :confused:

Thanks

I would look at 5" of backspace on the rear to better center it up in the well, would also give you the option of moving up to a 275 with no problem.

Rallyes, no "and"s "if"s or "but"s about it...
But, if you actually LIKE aftermarket wheels than I am not the person to ask...
:Smarty:

[Rixster]

Hey nicholas, would you consider rallyes from Wheel Vintiques aftermarket? How about the setup i mentioned? Front=15x7 235/60/15; back=15x8 255/60/15. The rallyes keep the original look & the more i thought about it, that is what i want. Now i just have to figure out the best looking stance. The car has factory heavy duty springs on all 4 corners.
Thanks,
Rick

That sounds like a nice combo Rick, and should give you a nice stance for the car too.

I'm going to running something similer on my 69. 15x7/245 front, 15x8/275 on the back.

[Rixster]

Thanks, Jim & everybody else for that matter. As far as backspacing goes, will 4.5 backspacing be ok for the back & 4 for the front? Wheel vintiques rallyes' are special order for 5" backspacing. Any other vendor out there that sells new rallyes'?

Thanks,

Rick

Nope, that's what my slicks are mounted on!

poor car.

anyway, that's a 235/60 on a 15x8. i have 4 1/8 BS and i could fit a 255 in the back as the max, probably. a 275 would probably rub inside of the wheelwell lip. a little more BS and 295's would go on easy.
