I have a 06 Titan LE. I just put 22" Millani Wheels w/ 305/40/22 Toyo Open Counrty A/T Tires. The tires are currently at the Mfg. recommendations tire pressure, but they look like the tire pressure is too low. Looks like i need to add some psi to the tires. I saw a discussion about this early last week. I was not able to find it again. Any help would be appreciated.
:cheers:

Spec sheet states 50 psi max, (it should be listed on the sidewall too). Try 40 psi and see if you like the look, and more importantly the feel.

No 45 series. Yes it's 31.6".

Toyo makes a 22 A/T in a 50 series. 34.8" x 13", (13" width on a 10" wide rim), LT325/50/22. Needs a 9" rim minimum, and would be about 12.5" wide on a 9". Would need at least a level kit and 5.75" to 5.5" backspacing, (+12mm to + 18mm offset on a 9").

The Nitto Terra Grappler A/T, (made by Toyo), has several 22s, with the best match for a stock Titan being the LT285/50R22 E 121R P/N 200-840 33.23" x 11.54 on a 9" width. Range of recommended widths 8.5-(9.0)-9.5, but I wouldn't go over a 8.5" or maybe a 9", and still shoot for the backspacing numbers I mentioned above.

You can save a bunch of money on both rims and tires if you go with 17s though.

Nitto doesn't list that size of tire on their website. Where do you see it?
What rims, and backspacing or offset?

The Mazotti's ? in a 22x9.5 at tires1010 have a +10mm offset, (Tirerack.com has the same info.), so their backspacing is about 5.6", about stock, but will stick out 1.4" more.

The Nittos in a 285/55/22 are 34.4" diameter, so with a level kit you will probably have some pinch-weld-modification and mud flap modification to fit them.

The 285/50/22s are only 33.23 " diameter, and a bit narrower, so would be a much better choice for a really wide rim like these ... still might need some trimming, but not as much.

40PSi is the recommended tire pressure for your ride. The wheels since they are a smaller profile will look "low" but are indeed intact. Unless you are towing anything with your truck. They could be exceeding the max load on the tires.

that last post was correct. what people dont realize is that even tho the tire size changes, ie from an 18 to a 22, the psi remains the same in MOST CASES. you cant think of a psi as a normal numerical value like a size. its pounds PER square inch. so even if you increase the square inches on the tire, the pound pressure per square remains the same. for example, if i had said 18 and 22 tires next to each other, completely falt and started filling them at the same time, the 22 would take longer to fill because it has more void, but you would still end up with (for example) 40 pounds at the end for each. the 22 would take longer to fill, but the punds per suare inch would be the same. this does not apply to xl or lt capacity tires, as this changes, and some vehicles have special fitment notes saying a size is approved if a higher psi is used, thus increasing its load capacity. those are acceptions
