To use the Tire Calculator, enter the top part of the
data into the form. For Example P255-50R-15
Would Enter 255 for the Width, 50 for the Aspect
Ratio and 15 is the Rim Diameter.

Note that this is the CALCULATED  way to
determine the size. For exact, look for the tire specs
that you can often find online. The TireRack is a
good source of that information.

These are the tires I currently run on "The Ripper". The
Victoracers (v700) are looking like they are being
phased out as they have less available sizes these
days. The V710's are what I normally use. They are
great tires for my use and I have not yet tried any other
brand on "The  Ripper". The VSE Cobra has BF
Goodrich R1's. I purchased a set when they first came
out and before the discontinue of the racing program.
Well the have restarted it! I have reduced the size of
the rears on the Cobra to 315's just to make sure they
are not going to rub so they are the new series. The
335's might be a tick close to the outer fender, and I
should likely need to change one of the rim half's to
make the wheel wider (towards the inside) and the
335's will go without a glitch.

The GT40 is rolling on BIAS ply AVON tires. The are
small in the front, and big in the back. That is all you
need to know...

The Tiger is running on street radials but will likely get
fitted with 205-50-15's all around, with the possibility of
225's on the back. The Tires I would use are the
Victoracer V700's but they don't offer those sizes
anymore. They do in the V710's line, so twist my arm.
And of course as stated in the tire instructions these
are racing tires and although they are DOT rated
should not be used for street driving. Right...
