Title: More tire questions
Post by: Johnnie & Susan Laird on May 11, 2016, 06:36:13 pm
Ready for tires on a 1994 - U225: -----has Toyo 9R-22.5's now. ( built in 2009 )

My trucking friend says the 9R-22.5's are hard to find if you have a problem on the road !

( I'm looking at Toyo's )

245/75R 22.5  are 37.0 " tall vs my 38.1 " tall  - and 9.5 wide vs my 8.9 wide. * hate to loose any height because of hyd jacks. * these are ok with my 6.75 " rims.

265/75R 22.5 are 38.4 " tall vs my 38.1 " tall -- and 10.0 " wide vs my 8.9 " wide . * says this one needs a 7.5 " rim vs my 6.75 " rim ?
I like this height but am concerned about the extra width ( on rear duals ) and the rim width.

Michelin's are not an option for my pocket book.

Can you help ad to my confusion ?  Thanks for your help..............~Johnnie Laird~

Keep your old casing as a spare and stick with the size you have, thus eliminating finding a spare on the road... I dont know enough about sizes to recommend anything else.

You may be right.  We don't have room to carry a spare in/on the U225 but................... no more than we get to travel the odds of needing one are pretty long.  Thanks............. :) ..........~JL~

You mention: " hate to loose any height because of hyd jacks."

So, lets start with what may be the root cause of the problem.

Have you checked RIDE HEIGHT?

There is a "ledge" behind each tire/wheel position.  Factory spec from there to ground (yes, level ground, jacks stowed) is 32-33"

Measure and post:

Ride height at each wheel position.
Number of shims behind and in front of each of those wheel positions.

Note: REMOVING one shim RAISES ride height 1/4"

If questions, PM me and we can visit.

Yes Brett,  know what your saying.
The ride height is correct now.  ( I don't have any more shims to remove )
Every thing is fine on a perfect day.  On good solid ground or pavement.
In the grass where it settles just a bit,  have to use ply wood 'shims' under the rear.
No big deal,  just was not wanting to make it worse.
Thanks for your help................~JL~

There are a lot of less expensive tires in that size from other less known brands.
