What are your axel weights and what is the recommended tier pressure? What load range tiers are you running? Did it drive ok before?

I feel a little unprepared for providing the necessary info for this. Sorry. I need a few days to collect the relevant data. For tonight, all I have is the receipt which only shows the tire size -- OSP truck 245/75R 22.5 Toyo M154. They are steel belted radials, but I don't know the specs yet.

I'll try to find a scales for actual weight and also get the GAWR. I know I'm loaded pretty heavy. The tire store told me the max pressure was around 120 lbs, but we set them all to 100 lbs. I asked if increasing the pressure would help and they didn't 'think' so.

I thought the word "suddenly" would indicate a change from good to bad handling, but I didn't really make it very clear. Yes, I was always so pleased with way the rig handled before - like a dream actually.

I don't know if the store kept any kind of record on the removed tires, but doubt it. Being a 1998, it was the old style of tire size and I'm sure they made an effort to match up the new tires. They said the size difference was less that a quarter inch in height and width.

You may need a four wheel alignment, and ride height adjustment, not just front wheels.

If I need to follow through with the alignment, I'll definitely inquire about this.

I sure appreciate all the support on this question so quickly. I'll get back ASAP with the other pertinent info.

Here is the tire info from Toyo:

There should be a decal on the wall close to the driver's seat listing the GAWR for both axles. It should also list the tire size and required psi. The pressure requirement will be different now because the tire size changed. Make sure your tires pressures will carry this weight.
The tires they put on have a different cross section and have different characteristics than the OEM tires. I'm pretty sure the OEM tire size is currently available, these guys just couldn't be bothered to get them for you.
Look at the date codes on these new tires. They may have sold you old inventory that they wanted to move.

You can call either Fleetwood or Freightliner with the chassis number and find out the OEM tire size and the GAWR if you have trouble finding them.
