8" WHEELS & TIRES WHO RUNS THEM? FAIL OVER 55MPH?

[Treeview]

100mph on an 8" wheel is 1900 rpm. Whoever heard of a ball bearing that couldn't do 1900 rpm?

Let's see. That would be 100 mph divided by...carry the...hmmm.

Andrew, I'll take your word for it.

Is that the Aggie way of calculating?

HELLO........ all the math.... I have a headache...... I just wanted to know if I stay with my wheels under idea
with 8" wheels/tires will, I have a massive failure tire bearing or otherwise. The general view appears to be if I
use good high speed grease and repack every season and find some good quality highway speed rated tires, I should be good to go. Right?
I just don't want to make a massave mistake. Thanks for all the feed back.

My younger son has a NAPA parts store & tells me that over 90% of on-the-road bearing/axle failures he sees can be traced to extreme overloads and/or poor/no maintenance of the 'rolling' components, regardless of wheel/hub/bearing size.

I learned that the hard way ... but before I owned a teardrop ... I owned (still do) a 4 x 8 ft "utility" trailer (from Northern Tool not Habor Freight) for years ... but was not very good on greasing the bearings. In the end one day while towing it home I started to hear a squealing / screaching coming from the rear. I was only about 15 miles from home and not on the highway so I kept driving. I got home but .... the next time I tried to move the trailer I found that the wheels were WELDED to the axel :-(

That experience has made me be sure to grease my bearings on my teardrop at least once a year (don't take it out that often, nor for long trips)

I burned out my fiirst set of tires with about 2500 miles on them this last weekend. I blew one out and had to replacement it...was able to drive home on the other one but it need s a replacement. I was running 12x4.8 weight range c. I need to see if I can squeeze 13's in there if not the 12x5.3's just for a wide higher weight tire. Guy at work said I shouldn't have been driving like 70mph plus when its 100'outside...speed and road temp. Could that be why I wore through them? Sadly I need to upgrade to 5 bolt hubs too...sigh

Well after measureing I have 2.5" on either side of the tire well at whats almost the top of the 12" rim




I can totally do a 13" tire, possibly a 14"

any thoughts?
