Re: [Chrysler300] Tire Math

["RON KURTZ" <Mark268@xxxx>]

Hello, everyone:

I recall someone had a link to a site that did tire size comparisons. I saw
this on the list server about a year ago. It's a real handy tool. Maybe they
can share it with us once again.

According to my tables, 205/75R14s are very close to G78x14s. You can go to
a 215/70R14 without having too much effect on the speedometer (but watch
turning clearance in the front wheel wells).

14x6 rim sizes are typically recommended for 205s and 14x6.5 sizes are
recommended for 215s for optimum tire handling performance. However, on
Chrysler stock rims, I believe a 14x6.5 has a different bolt pattern than
the 14x6s. If you want to use the 14x6.5 rims, be sure to check the bolt
pattern (The distance between every other hole on the rim.)

It's been a while since I played with this. Maybe someone out there would
like to correct or add to this.

Best regards,
Ron Kurtz

A very happy holiday to all!

says that the wheels are 14x6K and that they take a 8.00-14 size tire. But I
noticed that the same year New Yorker uses the same wheel (14x6K) and takes
a 8.50-14 tire. What's the difference? The car currently has G78-14 bias ply
tires on it from the previous owner. I don't have a clue if those are the
right size. I called some local tire stores and they couldn't agree on
weather I needed a 215/75R14 or a 225/75R14. What's the difference there? I
guess I'm just 'under-educated' when it comes to tires and sizes.

stay with bias ply tires for originality or use radial ones for better ride.
I assume the radials handle better and are safer. Is that the case? I do
drive the car a bit, it's more of a driver than a show car. Is there any
drawback to radials, other than not being bone stock?
