Default rear tire failure blow outs

In the past I have had a quite few rear tire failure blow outs over the years and it is very difficult on the side of the road to change rear tire on my 62 Cadillac Eureka Hearse.

I have commercial rims, balanced with Radial 235-75 15- 108S. Use different makers including Perelli. I keep it at proper pressure.

I want to switch to white walls. Can anyone recommend a good white wall radial tire.

Thank you

Yes. Don't put radials on it. You can get an appropriate sized white wall for the vintage and you eliminate the blow-out issue!

Make sure whatever tire you are buying is rated for the weight of the vehicle. But better yet, maybe a Honda Accord is better suited to your needs since any parts are readily available and even a simple mechanic can work on them

Rickey I think you need to read up on tires and load ranges. Your hearse is way heavier than a passenger car about 7000 lbs vs 4500 for average Cadillac of the era. So passenger tires don't cut it especially if you are carrying anything heavy. Also underinflation is a prime cause of blowouts though the book of the era on inflation says 25 to 29 pounds WRONG should be increased to 35 to 42 Pounds to help tire to run cooler. Get a copy of Hemmings Motor News many vintage tire companys advertise there call them discuss your needs the weight of the coach and any loads you expect to carry they are in position to advise you on whats best and they want your business. No need to buy a Honda.

Origional tire was rated as 2400 lb at 40 psi. The hankok optima is the tire yor looking for if you want radials. Keep max psi in them.

Do I have to use bias ply? Are bias ply stronger that radials for the size?
I already have radials on it but one bad rear tire. If I did have to go bias ply can I leave the radials on the front and put bias ply on the rear where all the weight is?

My Hearse weighed in at 7200lbs when it came into Hawaii from California.
I dont carry alot of heavy things.
Thanks

My boy why don't you call one of the tire suppliers and become more educated about tires. You can not mix tire types PLEASE talk with knowledgeable tire people and solve your issue. I have owned Pro Cars probably since before you were born and have never had a tire blow out. The only blowouts I ever had was before the days of rollbacks when we towed junkers with rotted tires in.

I challenge the weight of that rig. It's a hearse not a equipment loaded high to ambulance. It will be under 6000.in fact just over 5000. Has been my experience weighing them. If you are blowing out tires. Were is it rubbing. Your driving fast or caring anything heavy. Either the car is dog tracking or under movement its rubbing some place. Is it the same tire going everytime?

At weigh station in Honolulu where they weigh it for road tax when I was changing to Hawaii registration for this California car I recall they said 7300lbs. Guess I recall wrong.
Dont drive fast. No rubbing. I do carry some things. Always been radial tires. I think its always been the drivers side rear. Mostly sidewall blowout.
