What is the biggest tire I can fit on my new Xterra?
You can run a
33” tire, also often referred to as 285’s (click
here for more info on tire sizes), on a
stock Xterra with a mild modification known as the
melt mod. With no modifications you can mount a 32” tire without issue. Anything larger than a 33” tire will require a lift and likely some trimming.
Trim: X,S, and OR:
1.) 255/85/16R - Diameter - 33.1"
2.) 285/75/16R - Diameter - 32.8" -most common size
Trim: SE
1.) 255/80/17R - Diameter - 33.1"
2.) 285/70/17R - Diameter - 32.8"

Will it Fit and What has to be Done!
I made it this morning because I am sick of ALL can i fit this questions...for every size tire.
Tire Size | Diameter | What has to be Done
265/70/16R | 30.6" | Nothing, stock X and S sizes
275/70/16R | 31.2" | Nothing
265/75/16R | 31.6" | Nothing, stock OR size
285/70/16R | 31.7" | Nothing
285/70/17R | 32.7" | Melt Mod
285/75/16R | 32.8" | Melt Mod, and/or mild SL or BL
255/85/16R | 33.1" | Melt Mod, and/or mild SL or BL
295/75/16R | 33.4" | 3" SL AND significant fender trimming
OR
a BL and SL and a little fender trimming, wheel spacers or TS
305/75/16R | 34.0" | 2" or 3" SL, BL, some fender trimming, wheel spacers or TS (if this size even exists....)
315/75/16R | 34.6" | 2" or 3" SL, BL, more fender trimming, wheel spacers or TS
* Please note for those of you with 17" rims (SE xterra) your aspect ratio will change from 75 to 70...so the equivalent Tire to a 315/75/16R for a 17" rim would be 315/
70/17R. These two tires are pretty much the exact same size but will fit their corresponding size rims.
* Every tire company is going to manufacture their tire smaller or larger than the actual calculated measurement. This means that you may need to make slight modifications based on which tire typ and manufacturer you select.
