Stock rally wheel question

On stock 14 X 7 wheels what is the tallest and widest tire you can get away without rubbing or any other issues on a 70 Chevelle?

Re: Stock rally wheel question

For me, this begs a different question first. Do you ever intend to upgrade your brakes to disks? Most rotors for disks won't fit inside a 14 inch wheel.

Re: Stock rally wheel question

If you look at his garage, he already has the correct wheels for a 70 SS that work with disc brakes. He probably already has disc brakes in the front.

As a service to you I'll just add that the term "Rally Wheel" denotes the slotted steel wheel that was introduced in 1968 and is painted grey.

A 1970 Chevelle SS396 / SS454 would have come with the "SS Mag Wheel" (AKA: Magnum 500 Wheel), like Cindy is wearing in your Garage photo. A 7 inch rim width isn't going to get a very wide tire. If you wanted to go to a 15x8 wheel you'd easily get a 28" tall P275/60R15 on the rim. 15s look better anyway.

Re: Stock rally wheel question

My bad on the wheel description. The car has factory disc up front and I believe has the SS Mag Wheels. If I knew how to post the cars photo I would. Sorry.

Re: Stock rally wheel question

The two biggest 14" tires that I know of are the one that Diamond Back sells HR78-14 and BF Goodrich 245/60-14....

I prefer the FW Rally wheel but that only comes in 15 x 7 with 4.25" back space..

For the best performance, you want the tread width and wheel width to be the same or the wheel slightly bigger..

Re: Stock rally wheel question

225/70R14s are the best bet for stock 14x7 wheels. 245/60R14 is the only other commonly available option, and though they are wider, they look too short (IMO).

Re: Stock rally wheel question

It's not about what you can fit on a 14" wheel, it's about what you can find for 14" wheel since 14" tires are almost extinct.

Re: Stock rally wheel question

195/75 are easy to find, close to stock size, 205/75 decent, then 225/70 which is what I would recommend are limited, but available. Anything other than those, prepare to spend a lot. I got 6 205/75-14 Douglas (I think) USA made (Goodyear plant?) for/from Walmart on sale for $35 each! A couple hundred bucks for 6 tires, 5 mounted, 4 balanced out the door. Nice safe new tires that are, well, tires. Nothing special, and I think they have a lifetime of the owner warranty. (well, maybe 40K miles, but I'll never put that many on it now, it took 20+ years to get the last 30K on it)

Re: Stock rally wheel question

Diamond Back is the only place that sells big 14" tires.. They have a HR78-14 radial.. Its a great looking tire. I saw a set of these tires on a 65 Pontiac 2+2 with Pontiac 8 lug wheels. It looked superb!!

Okay, so we know th OP is talking about SS wheels, but since the title mentions "Rally wheel", and people may find this thread in the future from a search, I thought I'd clarify;

ALL Chevelles from 1964-1970 used 14" wheel, only, and many of those (67-70) had disc brakes. 1971 and 1972 non-SS Chevelles with disc also used 14" wheels. Many companies (Right Stuff, Summit racing, CPP, etc) sell "clones" of the factory 69-72 A-body disc kits.

IIRC, Rally wheels were required for 1967 disc brake equipped Chevelles (and 1968?). And most "non-disc brake" 14" wheels won't clear factory disc setups.

Sure, many "modern" brake setups will use larger rotors that may not fit 14" wheels (and many not even 15" wheels). But someone wanting to run 14" wheels probably isn't thinking of huge disc brake rotors anyway...
