Bias-ply load range question

[Uzzah]

had a tire separation on my 1 year old bias-ply tires yesterday. I have a 31 foot 1976 sovereign, with tandem axles. The rear drivers side tire has side wall separation, and a chunk of tire missing from the tread. Not sure how that happened, but that's not the important part. The tire shop got me a new tire and all is well, until I looked and noticed that the new tire is a load range E, and my other 3 tires are load range D.

I called the tire guy, and he said it was no big deal, but I can't stop thinking about it. The tires are the same size (7.00x15).but one tire is obviously not like the others. The tire guy said just inflate the E tire to the same pressure as the D tire. Should I push for a load range D tire,or is it really no big deal?

Go with the E and don't obsess on it. I use bias, and have for years, ....you will not have any problems withe the E/D.

[Uzzah]

Just keep them all at the same PSI?

[Phoenix]

Yes, same pressure in all tires. Also, I agree with Melody Ranch's comments above -- no big thing about D and E load range mix. Only a problem if you need E's due to weight and use a D instead (under-rated tire).

Almost made it home, had to leave the AS in a parking lot till I can get another spare tire. Lost both my rear axle tires on the drive home. Lucky I'm only 2 hours from away. Guess it's not just Marion's that fail all the time. I ran 5k miles last year with out a hitch, this year I can't even get 700 miles. Tires are just a year old.... Hopefully I can get some assistance from Discount tire. Guess i'll be getting some truck tires too!

Just drove home 100 miles on 3 bias-ply and one radial. Noticeable temp difference between the bias-ply tires and the radial. At this point I guess I'm going to make the switch over to radials.... But I think there may be a bigger issue with the axles, or the hitch angle, based on the fact that I lost both rear tires within a couple hundred miles of each other.

It sounds like the tongue height is too high and you are transferring too much weight to the rear axle. The trailer should set level or parallel to the ground when hitched to the TV.
