I have a 2001 Z302 on a Prestige tripple axle trailer, and pretty much every other time i take it out i blow a tire.

Now bearings are good, PSI are all at around 45, and im traveling at around 70mph average,

If anyone has any input on these it would b greatly appreciated.

Thanks Luis \

Oh yeah and they are 215/75/14

What kind of tires are they?

You must be in one big hurry to get to the lake luke!
If they are ST trailer tires , your running way to fast with them. They are only rated for 60 mph max.
Running that kind of speed , you need a LT rated tire , which is very hard if not impossible to find these days in that size.
Tire pressures should be at max , which is 50 PSI , if indeed you have ST tires.

Heck yeah we're all in a hurry to get there! Might be on the losing end of fuel mileage there though. I would be scared to haul a 302 at 70mph.

I get 13.0 at 75 roughly 14.2 at 65 to 70 at between 60 to 65 i get around 15.4 so it being almost 9k lbs i dont think 13 miles per gallos is too bad.

Got to love them diesels.

Oh and the tires St

So i guess i know why i keep blowing tires

[luke7575]

The speed limits here in Texas outside every city is 75 and lowest is 65 on highways

I think I'd be going to a 15" tire/wheel combo with the tires being LT Series if you got room to do it.

ST trailer tires need a drastic revamp in order to stay up with the times.
They have been a issue for quite sometime now.

As for the minimum speed limit..........I would hope that doesn't include trailer hauling vehicles.

no i doubt it but i hate going under the speed limit even when im doing hotshot work im never under the speed limit unloaded trailer or towing 20k lbs i dont like it

[luke7575]
