FIA Tire Size
I'm buying new tires for #2049. It currently has 295/50-15 (rear) and 235/60-15 (front).
I have the rears already, but what is ideal for the front? 235/60-15....current set up 235/65-15....fill the well up a bit more? Something else? Thanks |
The difference in diameter is almost +1". That means the car will have to be lowered in the front ~1/2" and you will lose 1" at the top of the tire. Do you have the clearance?

Bob,
I'll post a picture I have...it will be later today after work. Thanks |
I would go with what you have now in regards to sizing. Your car appears to sit "just right" to me. FIA cars do have a different stance/tire to fender clearance than a street 427.

I doesn't even look like Avon does a 235...
225/60-15 or 225/65-15 |

I'm really outside the norm in that I went with 215/70-15 on the front and 255/60-15 on the back. Both are a just shy of 27 inches tall and fill the wheel wells fairly well. I had to shave the rear of the left front wheel lip down at the rocker slightly to get the front ones to clear.

I run the Power cushion up front, small yet tall. G7 in the rears.
Well balanced but not the best for track. |
So we are talking AVONs right?
I believe it's 225/65/15 for the front - that's what I had up there before I switched to MT's recently; no 235 size; I hear that people have gotten away with 245s in the front but some or all have clearance issues. btw, the MT S/Rs I got for the front fit better than the Avons: 26x10x15s fill the wheel-wells better and sit a bit lower. |
is 2049 the blue one (with no stripe out of CT)?

That answered my question Bob...perfect. Thank you.

Well, not the best picture....just a quick one with my phone.
Avons installed... Front: 225/65-15 Rear: 295/50-15 This is the same set-up I had on my 427 street car. Thanks again to Nick Acton. http://i221.photobucket.com/albums/d...psanohqffn.jpg |
I'm happy with my 10.26.15 fronts and 12.26.15s in the rear. My FIA has a little bit of a nose-up attitude, veddy British-ish.

Thanks for that information. I am trying to figure out which tires to run on my 289 FIA SPF/Riverside Racer. The racing organization that I will run with is specific about tires and sizes. I am going to go with Hoosier Street TD's and the sizes that I am allowed are: 225/60/15, 245/60/15, 275/60/15, 25.5/8.5/15 or 26.5/9.5/15
I am a little concerned about having adequate clearance, and also wanting to make sure that I have adequate rubber on the track. 245 seems way to small for the back, especially given that the 289 will have approximately 450HP at the flywheel. Any thoughts? I am starting to lean towards 25.5/8.5/15 in the front and 26.5/95/15 in the rear, as they are a little less tall and slightly wider. that will help lower my center of gravity a little and increase grip. The car has transverse leaf springs, so lowering height means placing lowering blocks over the leaf springs. |
