914World.com _ 914World Garage _ Tire recomendation for flared 914-6 3.2

Posted by: ken914 Feb 17 2005, 09:17 PM

I ADDED A PHOTO OF MY "NEW" CAR. SCROLL DOWN ABOUT 15 POSTS...

After 4 years of searching I just bought a 914-6 with a 3.2 and flares! The car is in route from California to SC, should have it in a few days! I can't wait. My first car (1981) was a 1971 1.7, then a 2.0, have always wanted a -6

The car is going to need tires soon, it has 15x7 and 15x8 rims. The suspension is very stiff and the frame is stiffened (with dog ear stiffeners).

I'll use it for AX, PCA events, running around town, AND JUST HAVING FUN.

I was hoping to get new 285's to replace the 285's on the rear but nobody makes them anymore. What do you guys recommend for tire type and size for this car???

Thanks for your help!!!

I raced the car attached for three years with 15x7's and 15x8's. I ran 225's all the way around. I do not think you should run larger than 255's on an 8 inch rim.

On a Chevy, with a 17" rim that is 8.5" wide, the maximum recommended is a 275, although people were running 285's on a regular basis. Not sure if you can get away with the width though because of the rim being a smaller height therefore more sidewall though, so you can curve it in though.

I have 225's on mine, not sure of the rim width, I run like 20 PSI in my tires and have fun with it on the street. I don't take it to the track though.

Check out www.bridgestone.com and look at the high performance Potenza wheel chart. 225/50R15 tires call for an approved rim width of 6-8 inches.

225/50R15 91W W BW 101-222 6.0-8.0

How the heck where they fitting 275 on a 8.5 in rim????

We talkin trucks here?? cus it would have to be a large diameter tire.. (275 70 17's or so..)

I'm talking 94-96 Impala SS's. They come with a 255 stock.

Goodyear G-19 slicks.

on the front 7" setup, I wouldn't exceed 235, on the rear, that can go up to 255. I'm forgetting the overall rolling diameter of a 914 wheel/tire combo so I'm not sure of the profiles that you should be going after.

Here is a http://frisbyracetire.com/t1s2004.htm that should help with your choices.

I have 225 - 50 - 16's all the way around on 8" wheels on my flared 3.0 / 6.
This set up seems to look and perform well for me.

Congrats on the new car Ken. You're gonna love it.

hoosiers for the track offer a 245 that will fit on a 8". I belive outside of slicks thats as big as your going to get. Otherwise you'll need 16"s..

Posted by: SLKWrx Feb 18 2005, 09:23 AM

So is 25" the optimal rolling diameter? because if so, your choices are much easier to figure out

285s on 8" rims?
i'd say 225 for the 7" and 245 for the 8". good tires are still readily available in those sizes.

just FYI, the factory ran 285 on 9" rims ...

I was just checking a Yokohama tire brochure. Their recommended maximum width tire for a 7" rim is 225 and for an 8" rim is 255.

i've got 225's on my 8's (front) and 255's on the 9's (rear), my next set of tires (those nice Falkens everyone is raving about) will be going on as soon as they start to deliver them....265's will be going on the 9's...rims are 17" dia.

Posted by: 1973914 Feb 18 2005, 02:03 PM

For what you are doing, 225/50/15 on the front and 225/45/15 on the rear.

Here is a photo of my car.

Thanks for all the help.

Have you considered stepping up to 16" or 17" wheels? If you have real Fuchs on there now you can probably sell them for enough to get some bigger ones. The 15 x 7's are in high demand.

Posted by: anthony Feb 18 2005, 10:54 PM

16x8 and 16x9 Fuchs are also in high demand.

Posted by: Andyrew Feb 19 2005, 12:56 AM

So... Does this mean I can run 265/40/17's on a 8.5 in rim??

Or even a 275/40/17??

I could fill out the bontempi flares better with more tire...

Posted by: iiibdsiil Feb 19 2005, 01:47 AM

I don't know that you will get it with that sidewall, but most likely, yes. The sidewall might be too short, although a 255/50 and a 275/40 are probably pretty close, ey?

Here are what I assume are NLA 285-40-15 Pirelli P7s:

yupp, those are the ones ...

BUT

they haven't been made in 15 years or more. those tires are OLD. they're probably hard as a rock.
i wouldn't touch them with a

if your life means anything to you, don't run tires that have been sitting for 15+ years ...
