Hey JR if you would have come down to Arcadia, you would have seen a great deal on 2 almost new Michelin XZX 315's mounted on polished Alcoa's for $500.00 but since you weren't there, I went ahead and bought them! LOL

Belfert,

We run 120 all the way around. I know I might get in trouble for this from some guys here ( Grin Cheesy Grin), but I do that because we are pretty heavily loaded, and because I don't want blow outs.

YMMV

God bless,

John

Belfert & John- Have your bus axle weighed and I can look up your tire pressure if you'd like.  For instance, I have 11R-24.5 16ply Michelin XZE's all around that are rated at 7,200lb @ 120psi for the front and 6,600lb @ 110psi for the rear (per tire).  But since I only have 10,500lb on the front axle and 20,500lb on the rear axle, I run 90psi all around.  Nice riding.  Good Luck, TomC

I did have each tire weighed.  The 75 PSI is based on the Firestone weight/PSI table.  75 PSI just seems really low to me.

Brian -

When you had the coach weighed, was it in "ready-to-roll" trim, or did you not have all your "stuff" inside?

If you feel that 75 psi is too low, adding 10-15 psi would probably not make a significant difference in the ride of the coach, but would certainly help relax those feelings you're experiencing.




We run 120 all the way around.  I know I might get in trouble for this from some guys here, but I do that because we are pretty heavily loaded, and because I don't want blow outs.



John -

You say that you're pretty heavily loaded. . . have you run your coach across the scales to see how heavy the bus actually is?  Until you do, you really don't know if your tires are inflated properly, and, in fact, you might actually be INCREASING the wear on your tires by running over-inflated - blow-out protection or not.  As usual, do it your way. . .   Wink


JR -

Another tire possibility is either 11R22.5 or 11R24.5, especially if your coach is pretty light.  I saw quite a few coaches down in Quartzsite three weeks ago with these sizes on them, including on several 40-footers.  Very, very common truck tire size, readily available nation-wide, and often less expensive than the 12Rs or 315s.

OTOH, 12R22.5 was the stock OEM tire on your MCI. . .

Remember, too, that changing tire sizes will have an effect on the overall accuracy of your speedometer & odometer, and some effect on fuel consumption.

FWIW & HTH. . .

 Posters often mention looking up tires on charts. What is a chart? where does one find a chart?

 Here is one     http://www.firestonetrucktires.com/us_eng/home/index.asp
 
Click on load and PSI tables   I'm not recommending Firestone, I would not buy them. I am not going to spend $600 on a tire that will sit and rot.

 Type in search bar  type tire you are interested in     Brand XXX   truck tires or commercial truck tires or medium duty tires and it should take you to a site where you can find all the info you need on tires, load range, rated speed, rim size needed, RPM's inflation pressures etc....   HTH  Jim

I didn't see any steering improvements after lowering the PSI in the tires.  I'll put more air in before my first trip of the year.

I'm going to need to check into the proper adjustments for the torsilastics, but everyone says I have lots of adjustment left.

  Hey guys,

   On the subject of tires, here in Indianapolis FEDEX has  ( I guess from what I see) are disposing there older trailers at a

   recycling center.  There is unbelievable amount of tires taken from these trailers.  THERE NOT RECAPS, and for sale.

   The recycle center is OMNISORCE on Holt rd.  Might be worth checking out!

 JR;
 I forgot to mention on the phone the other night about the best advantage of the 3:15's. After my 17 years experience of driving ,I retired with (2) very important lessons on safety.They are: keep a good folowing distance;and these coachs will slide! The three axle coachs are likely to slide/or skid on the front axle,and the two axle,on the rear. Using the 3:15's on the front will give you a couple of extra inches of grip(which could be a life saver)I'm not talking about Icy,or snow covered roads,but just plain wet ones.
Thanks ;Bill

You guys realize that you can buy from truck tire dealers used guaranteed tires for the drive and tag for around $150 @  You will never wear the new tires out but age will so why pay all that money for new?
