Re: Wheel And Tire Size for 2005 Stock XE

The PRG level kit as well as the coilovers he sells, (follow my sig link), can be installed by any local mechanic, and even a lot of mechanically inclined members have done it. Bolt on with no spring compressor needed. There are instructions too.

I had a DR dealer quote me an install at over $300, but a local shop charged me $105. Only a simple toe-in alignment is usually needed. There are instructions here for that too. Same mechanic could do it for $25 or less, just search, and print them out.

Anyhow, stock sized Off Road pkg. tires, (don't buy the rugged trails though), will work w/o level, 285/70/17 about 32.8" x 11.1" on a XE or O.R. rim.

With the PRG level kit, you could run a BFG AT KO LT315/70/17, at around 34.5" x 11.6" on our wheels. However, I think 34 " diameter maximum is a better choice. My Titan is on 33s, and it is probably lifted about 3", and looks o.k. IMO. My next aftermarket size might be one of these: LT305/70/17 (33.5" to 34" x 11.6" to 11.8"), or LT305/65/17 (32.7" x 11.6), or 295/70/17 (33.2" x 11.8").

With wider rims these tires will be a little wider, because our rims are only 7.5", they are pulled in a bit. For example, the specs may say 8.0-(9.0)-9.5. This means they suggest an 8.0 to 9.5" rim, and specs were taken on a 9.0" rim. So if sidewall width is 12.36" (on the 9"), we need to take off about 0.2" for every 1/2" less of width. So for 1.5" less, as in our case, this is 0.6" less sidewall width, or 11.76". But manufacturing tolerances cause variation, so it can be less or more.

Btw, aftermarket rims with any of these tires may rub, due to either rim width or smaller backspacing, or both. All '04 to '07 Titans have roughly 5.5" backspacing, while many aftermarket rims have 4.5" backspacing, so even at the same nominal width they would stick out an inch more than OEM. [Wheels sticking out causes fender rub at the pinch weld at full steering lock].
