Severe pic attached and a question about tire (rim) spec.
Maybe I'll have better luck in the General section.
Lucky for me, it most probably happened on my street when I was returning from a drive last weekend. I felt the steering was a bit strange, got out and looked at all four tires, all looked good, tires fully inflated, checked the sidewalls outer/inner, all is good. Not finding anything peculiar, I presumed there may have been something afoul with the steering linkage, maybe?
First time I see this, a bubble on the tread? I guess so. What do you guys think?
And, it most likely burst as I turned into my driveway to park the car in the garage. I only noticed the following day when I got into the car and the right side felt low. Had a look in the front, tire dead flat. Ran my hand over the tire just beneath the wheel-well and there it was.
Wow.
So, I'm looking for new tires.
Question: When a tire is advertised with a rim width of 6.5 inches, will this be ok for the 8 inch rim on the car (1970 C3, stock rally rims)?
Thanks in advance.

Not always true, but it is in the case of your T/A Radials. No problem mounting on 8" rims.

Not sure, I'll have a look at the date code sometime this week and let you know. The car's in the shop for some interior work (seats, carpet) and of course, new tires.

OP, go to the tire manufacturer's site, in this case, BFG, and check what THEY say is the "acceptable rim range". I would say that with respect to the data you posted, 6.5" is the minimum recommended rim width.....

The BFG site only goes back to year 1993.
According to these tire info sheets from the tire dealer, the 235/70R15 is ok for a 8" rim. The 225/70R15 is for a 7.5" rim max.
What does that other measurement: 9.0 on 6.5 mean?
And, is there a risk of the tire rubbing on the fender with the 235/70R15?
Sorry for all the questions, I just want to buy the right tires.

Go to the Tire Rack & find this tire.
Click specs & then meas. rim width.
This explains it all...

A 225/70 will fit on an 8" rim no problem

The "section width" (9.0") is being listed, with the tire mounted on a 6.5" rim
I wouldn't consider the 235/70, as the OD is bigger than what came as standard equipment, which will mess up your speedometer readings, as well as potentially cause clearance issues.

I would recommend as DEFAULT 235/70/15 225's are a bit small and you WILL NOT have any clearance issues.
I think for forensics reasons you should post up the DATE CODE on the offending tire.
Good luck. I've had 40 years of good luck with the BFG's.
Glad you stopped in time!
Ps I had 225's on my 3000 lbs Audi TT and went to 235's....the 225's struck me as OEM 'too-small'

EXACTLY.... those aren't tires anymore, they are hand-grenades....each one hiding $10,000 worth of body damage.
I got 'flamed' the other day, when some guy 'found' the original 44 year old spare in his corvette and basically I said 'take pix' then chuck it, It's a disaster waiting to happen when you need it most.
Somebody post up a pick of the body damage an exploding tire does to a C-3....it's CATASTROPHIC,
General rule of thumb (and Discount Tire and the other big guys) is to replace the tires at 6 years. Okay that will start much foment. "hey it sits in a garage'.
answer, it's oxidizing from the inside and the outside and you can't see the delaminations. They are not saying that to sell you new tires....they WILL NOT ASSUME THE LIABILITY.
BE SAFE!

Are you sure you want to put a set of new BFG's back on? I believe they are made by Michelin now. I bought a new set 3 years ago and have had continuing problems with the white lettering turning brown quickly and never getting them a decent white again. If I had to do it again I would put redlines on.

May I suggest...Doing what I did on my T/A...
I got the red 'dye' pens....and meticulously colored the RWL's in red.
I get more comments at the cars shows about THAT, than the damn CAR! (grumble!)
"Where did you get those"? COOL!
Btw....the perfectly good BFG's (5000 mile) on the CE are 10 years old....I just replaced them. They had WHITE LETTERS. I could not bear to throw them away...going on a steel bodied vehicle.

Your car originally came with an F70-15 tire which has a outside diameter (OD) of 26.9" A 215/70/R-15 has a 26.9" OD also. A 225/70R-15 tire will have an OD of 27.4" and a 235/70R-15 will have an OD of 28.0", as previously mentioned. Expect small speedo error with 225's and 235's.

I would go with the 225 so your speedo error is smaller

Dear RedVette2;
In my case, it wasn't hard.
I did find it was easier with the tire demounted and on a table-top.
I cleaned the letters with Acetone...mainly because all those tire dressings have silicone in them....NOTHING sticks to silicone.
I was meticulous and took about an hour a tire.
Getting the right paint counts....hard shell paint will crack off. (lacquer)
I got 'DYE' pens.
Good luck... Personally this not buying a tire because of the lettering turning brown is s bit silly....but then again I lived through 'whitewalls'. They got dirty if you looked at them crooked!
I'm at a car auction a couple of years ago....there's a 61 T-bird up on a Quickjack in the forecourt. The guy has a rig that is grinding off the top 1/32 of an inch of the 'Wide Whites'. It's his business. I sat there mesmerized. After about 10 minutes a tire, he's done....they came out UNBELIEVABLE!
