69 Riviera tire options ?


Recommended Posts

Hi everybody.

 

After a long thought I finally got myself a -69 Riviera.

It needs new tires. I believe the wheels are 853 15x6, since the car has the factory discs in the front ?

 

I've been looking at the Cooper Cobra 235/70-15 and  Trendsetter WW 235/75-15 tires.

Will these fit without any modifications, since I'm trying not to mess with the original condition car ?

Or should I stay with the 225 wide tires ?

Teemu,

 

Suggest considering Hankook Optimo H724 - Size: P225/75R15 white stripe sidewall.

 

Forum members have indicated this to be a good tire at a fair price.

 

Please note that some do not like the embossing on the black portion of the sidewall.

I have run the blackwall Hankook's on some of my vehicles. These are great tires in wet conditions. If you don't mind a Korean-made tire, these are a great choice.

Don't buy the Hankooks...... the sidewalls have ugly black ribs beyond the whitewall with letters that say Hankook that are so big you can read them from fifty yards away. Go online and order some Venezia classic 787 whitewall p225-75 -15s. I bought mine online for 47.00 apiece, and they are the smoothest

 driving tires I've ever owned and they have a beautiful sidewall that looks like a 60's tire. They are made in China, and that might be a good thing. On my

enclosed car trailer, I used to have a lot of blowouts on American made trailer tires like Goodyear. I finally switched to Maxxis made in China and haven't had a failure in ten years of using them.

I currently have these tires on my 68. While the tire ride is excellent, I cannot keep the whitewalls white. The whitewall starts to turn brown within a week of washing and using Black Magic Bleche‑Wite on them. The comments about the Hankook name and ribs is correct, but I still think they are a great tire.

Thank you Gents for all the suggestions.

 

Ed, I read on an other thread, that you had slight tire rub on the 1st gen Riv.

What was the tire you were using ?

 

Has anyone here tried the 235s on a 2nd gen Riv ?

 

Hankook makes decent summer tires and on a standard vehicle I would not care about the looks because function overrides form.

Anyhow, with the Riviera, I have to admit that I'm not too keen to have the Hankook name highlighted on the side wall.

 

Any experience on the Cooper products ?

I have 235's on my 1970. These are American Standard from Coker. There are no fitment issues, even with the skirts.

Is it American Standard, or American CLASSIC? Planning on going with an American Classic in 225/75-15 on my 65. Seems to have somewhat the correct whitewall width that the original tri white stripe would have had when it was new.

I experienced tire rub with the 235/70 series tires.  But only at full lock.  I never experienced it while driving unless it was to pull into a parallel parking spot.  And then it only rubs on the head of a chassis rivet.  I've purchased Hankook tires for the last three vehicles on which I had to replace tires.  I don't remembet them having the name highlighted on the side any more than on any other tire.  The widith of the sidewall is the down factor with most current tires.  For a 1st generation RIviera, a 1-1/4" white side wall is about right.  I think that some out there are 1.3" which is really close.  But personally I'm staying away from Coker tires because you can't tell how old they are when you get them.

 

Nothing on Cooper for me currently.  Back in the late 60's my dad put a set on my '63 Dodge ex-state trooper Dodge.  They were good at 120 mph + (don''t know the + side: the speedometer only went to 120,) and the car would do that in 2nd gear of the Torqueflite transmisson.  Yes, I'm still alive to talk about it but only by the grace of God.  383 cubic inches, 335 (advertised) hp and a 2.79 rear axle.  It would rev to 6K rpm.

I have Cooper's on my '93, one of my '99s, and on my GMC truck.

 

They are a good riding tire, and have exceeded the mileage rating on the truck, I may never wear them out on the Rivs.

 

One draw back I have heard about is that the whitewall does not stay white. The ones on the '93 will clean-up pretty good, but the outlined white letters on the tires on the truck have cracked some, so they aren't in the best shape. Ride a durability are good, but I have had others say that the WW gets dingy fairly quick.

* When replacing Alpha Numeric tires with Euro-metric or P-metric tires, look for the Euro-metric or P-metric size listed in the equivalent aspect ratio. For example, when replacing a FR78-14, you would look up the appropriate 75-series size, the 205/75R14. If replacing a FR70-14, you would look up the appropriate 70-series size, the 215/70R14. If replacing a FR60-14, you would look up the appropriate 60-series size, the 235/60R14.

As it so often happens, I went with something else than what I had in mind and what was suggested. 

 

The local PepBoys had the BF Goodrich 235/70-15s on sale and available for $100/tire.

They don't rub at all, at least not at parking lot speed.

The speedometer is showing 5%  fast compared to the GPS.

 

A little worrying is, that they tried to lift the car from the body before I could interrupt them :(

The next guy knew how to lift the car correctly.

That's a great price for BFG's! Great looking Riv. Hopefully the shop did not do any damage to your car. :blink:

Note the 1968 tail light bezels on the 1969 above.  It has been said that some early 1969's had these but I'm not sure how many came off the line this way.
