Toe-in Change & Tire Wear
#1

I posted back in 2013 that my coach tended to wander.  New 365s were installed 2 1/2 years ago and I did not like the way my coach handled.  My owner's manual states that toe-in should be 1/16" and I had Newell change it to 3/16" which resulted in the coach hugging the road and much more fun to drive.  Of course I am interested in tire wear due to the increased toe-in.  I checked today and after 30,000 miles, each front tire shows wear in the center of 1/8" and 3/16" to 1/4" at the edges.  The edges show a little more wear because I only carry 110 lbs. of air instead of 120.  Frankly, I am satisfied that the increased toe-in did not result in excessive tire wear, yet the coach drives much better.

The wear due to toe-in will be the difference in wear between the inside and outer edge of the tire. Wear due to tire pressure being high or low will be the difference between wear in the center of the tread and wear at the outer edges. Too high pressure for the weight carried will preferentially wear the center, too low pressure will wear the edges.

Thanks Chester and Alie/Jon (not sure who is talking here)! I have noticed that I have to set the Howard Power Steering up to above 140 for the coach not to wander too much but still cannot just let go the wheel and it track straight. The 365s have been running great and I have them down to 105lbs of pressure after having the coach weighed but can go down to 100lbs if I like but would rather err on the side of over-inflated... We are a long way from Newell and will be heading in the opposite way soon. Where else would you recommend taking the coach to get the front end checked out?

Adrian,

Big Truck Alignment, Huntington, Tx, on Hwy 69, 9 miles south of Lufkin. Excellent alignment on straight axle front ends (they do not align independent front ends,IFS, on newer coaches). They also can true the steer tires making them perfectly round.

Haden Haskins taught Wayne at Foretravel how to align motorhomes. Wayne remembered most of what he was taught. But Foretravel folks that are in the know go there. They are worth the drive.

Newell uses an alignment system that is in degrees, not inches. Richard knows how to make the math conversion. I paid extra to Newell to get them to manually set toe-in to 3/16" because they were unable to make the conversion from degrees to inches.

Wow how time flies! Now I am showing wear on the passenger side front 365 on the outer edge of the tire. Is this a tie-in issue? I need to start looking at getting replacements I guess :-( anyone have a good line on 365’s?

If anyone can get 365s, Wendy Ward at National Tire Concierge Service can.....highly recommend their service.

Another Newell friend has a tire dealler friend. Dave and Wendy saved him $2000 on 4 365s over his friend's price. Dave 321/607-8465. Tell him Rudy said "Hi"

I also find myself steering more than what would seem necessary. At this point, it's straigh down the road with no wind, no road crown and 63 mph! My linkage is tight and very responsive. With any variation, I'm constantly, but slightly, back and forth on the steer. This leads me to believe a toe-in check to the 3/16" may very well be the right correction.

That leads me to my question. Should I remove my inoperative Howard Power Steering cylinder at the same time? OR, is there a seal kit still available given I find me a good cylinder shop in the middle of NW Iowa farm country for fix? Any suggestions?

Tony,

Your coach is a similar vintage to 653.   Have you seen this thread?  Rag joints
