My '05 needs some new rubbers, so I'm looking at all possibilities to save money.

I have an option to purchase a complete set of new OEM rims with new OEM tires. (Yes, this is being done legally) I have to settle with what the company has on-hand when they finally come in. Odds are, I will get '08 model rims, but they could be 4x4 or the nice new 20s!:idhit:

Questions:
(1) Are the lug patterns the same for all models and years?
(a) If not, which ones will fit my '05 LE?
(2) Will switching the rims out to any of ther other sizes throw off my speedometer?

Thanks in advance for your help!

I guess that should have been another part of my questions.

Has the overall diameter changed from the 18s to the new 20s or with any of the 4x4 wheel sets? I don't think it would b/c the wheelwells are the same on all models.

I may just need to get out the 'ol measuring tape.

Different models have different size tires and thus the speedo's are calibrated differently for each tire size.

For 2008, there are the following tire sizes:

P265/70R18 (XE/SE)
P275/70R18 (Pro4X models)
?????? for the 20" LE wheels. Not spec'd on Nissan site. I would assume that it's similar to the P265/70R18 though.


2007 and prior:
P265/70R18 (SE/LE)
P285/70R17 (XE?/OFFRoad)

Also, not much need to get out the measuring tape. You can safely clear 33" tires when using ANY of the stock size rims.

You do have to be careful in your selection, as some wheels require a tapered lug base and others are flat. I think the LE rims are flat and the SE rims need the beveled lugnuts, but I'm not positive.

My SE has the beveled lugnuts.

I believe that all titans that are SE/LEs have 33" tires, yes the widths and rim sizes are different but they are all roughly 33" around. I was a little supprised that Nissan did it that way but it makes it easier for them to have 1 size to diameter wheel to worry about.

Actually, my stockers are equivalent to a 32.5" tire (I know big deal) and measure out at about 32".

Ok, I went straight to the source, not a manual, technician, salesman, dealership, or tire store, :idea: I talked to the engineer in Farmington Hills. :bouncy: ..........I got connections. :smokingco

Structural reinforcements and shock-damper tuning changes were made to Titan MY08 for the 20-inch wheels and tires. If your truck does not already have the 20" tire-wheel countermeasures, they could increased stress to suspension parts during severe usage, bumpy roads, and high-load situations.

The 18" Off Road tires and wheels required no structural or suspension countermeasures.

Both the 20" and 18" Off Road wheels require Fender Lips to meet the regulatory fender coverage requirements of some states
