tire questions....

[Rose Mary]

Hi group
Have spent some hours the last few days talking to tire shops. Les
Schwab and Commercial Tire

Have 6 good toyos (only a couple years and less old) but they are
rated G. I've known since last year I needed to replace the steer
tires with a heavier rated tire. The duals I plan to run out some time
on....
Michelin 12 R 22.5 ZX2 had been recommended but have been out of stock
each time I inquire.
All the 11 r 22.5 seem to be underrated, the highest at 13200...still
not enough to have much leeway.
Today talking with commercial about a Yokohama 12 R 22.5 for a good
rating.
My question is -
there is + .5 difference in the overall height of the tire, compared
to what I am currently running (11R 22.5 Toyo) -will this difference
in pitch cause a problem with the driveline
(vibration, possible damage??). Wouldn't be an issue I reckon if I
were replacing all 6 tires but that isn't happening.....

Not looking for cheap, looking for right and safe, after this bird
experiencing 3 steer blowouts in the heat the past few years...the
last with me at the wheel. We've been lucky to have kept it on the
blacktop upright and no other vehicles got involved.

Equal to use or not to use, that is another question.....

Thanks

Good morning Rose Mary:

You will not have a problem with the 12 R 22.5 in the front and the
difference in height will not even be noticed when it comes to bottom line.

The Yokohama tires have gained a good reputation and I have seen allot of
them on coaches, trucks and so forth. Yokohama is owned by Goodyear but
don't let that stop you. They are good tires and will give you good
service.

I have run equal and it did a good job until I needed to add air and even
with the special filter type of valve installed, the equal kept getting
back into the valve and I would have slow but sure air leaks. I went back
to the spin balance and weight system and have just gotten over the fact
that at times the weights look like a blemish on the rim when in fact it is
a part of the tire, so be it. Ok now we can get on to the good subject of
"what kind of coffee are we having today."

This is one of those subjects where everyone has a different idea and
experience.

Safe travels,

The .5 difference in tire height won't affect anything if it's placed
on the steer axle. If used on the drive axle, you need to match all
tires to have the same rolling diameter. The different diameter may
also affect your speedometer/odometer readings.

Although others may have strong opinions about Equal, when I had to
replace a steer tire, it was 'spin balanced' with standard weights.
It appears to be satisfactory. If you use equal, be sure to have
filtered Schrader valves installed to avoid later leakage problems.
