Anybody running a 315 rear tire?

I remember this guy did a few years back.

For what model are we talking about ?

 

Could F355Bob be asking about a .......F355? Maybe? I wonder if his name gives the game away

 

Yup, I still have those wheels. They are P-zero corsas, really sticky (like crack, actually). Moving them over as soon as I have the time.

No spacers, no rubbin'.

 

lets see some pics of these 295's

 

i was running 305 last year with 18X12 rims on rear and 265 in front on 18X9 rims

wow
what a beast

 

Man, look those tires ! I wouldn't think they actually fit but they do !

 

Woooh! I need to get a set!
Not to be mean, but, the 360 behind you (like my 355) looks kinda skimpy in comparison!

 

Niiiiiiiiice work my friend! the car looks great.

 

Very sweet !!!!!!

 

That looks pretty darned awesome.

 

anymore pics of that beast please

 

The stock 265/40 18 have an overall diameter of 26.3 inches with 790 revolutions per mile. A 315/30 18 has an overall diameter of 25.5 inches and 817 revolutions per mile. Depending on what size front you are running, it can actually have a larger diameter than the stock 225/40 18 tires. I believe the correct rim width for the 315 is 11 inches. It should be about 1 inch less than the tread width of the tire to give it the proper configuration and thus handling.

A potential problem with a smaller diameter rear tire is that it changes the attitude of the car, in other words, the front of the car is relatively higher than the rear. In the 355 this changes the dynamics of the air flow beneath the car creating an aero lift at high speed. The 355 is known for getting "light in the front end" at speed and this will exacerbate this situation. The smaller tire will also give a larger gap in the wheel well. If the rear is lower to compensate for this, the change in attitude is magnified.

Depending on how you drive your 355 none of this my matter in reality, however, I could be helpful if you are driving on the edge of its limits. Some awesome looking pictures.

 

Great, informative post.

 

thanks for the compliments.

the front tires are 265/35/18 which have the same diameter as 225/40/18... (25.1")

the rear is 305/35/18 which have a 26.3" diameter. I have a set of 315/30/18 (25.6") I will be using this year.

 

anyone ever fit 345's on a 348

 

the bburago models on the 348 have 345's on the rear and it looks sik

 

Do you have any pictures of one?

And... what's a Bburago Model; was that a special edition 348? I've never heard of it before.

All the best,
Andrew.
