There are too many variables, re: different wheel offset/width, for a definitive answer to this question.

Dang it! Of course that will make a difference.

VX PROs - What's the max tire height before having to trim the cladding?

As L-Dub indicated there are many variables. However; on a 100% Stock "non-lifted" VX, the maximum tire O.D. hovers between 32.6" -- 33.3". The key is to use the skinniest/narrow tire available and the Stock OEM rims when using 16" or 18" tires. Use the narrowest rim width allowed for 15, 17, 20, 22 size tires. The skinnier the tire and the narrower the rim width, the less likeyhood trimming will be required on the VX cladding.

Here are the skinniest & tallest tires that will fit without "lifting" by rim size:

33/9.50-15LT (32.7" O.D.) (i.e. BFG - A/T)
255/85R16 (33.3" O.D.) - Use with 1999 VX rims (16x7)*
285/70R17 (32.7" O.D.)
265/70R18 (32.6" O.D.) - Use with '00/'01 VX rims (18x7)
275/70R18 (33.0" O.D.) - Use with '00/'01 VX rims (18x7)
275/60R20 (32.9" O.D.)
285/50R22 (33.2" O.D.)

* The winner is 255/85R16 (33.3" O.D.) mounted on 1999 OEM 16x7 VX rims. Your VX will look like a Stage-Coach with wagon wheels from the 'ol West, but there's your answer.

Disclaimer: The tire sizes listed above may or may not require cladding trim. Since VX's were hand-made; no two VX's are exactly alike and what clears on one VX may rub on another VX. Still, the above tires will fit on a 100% Stock "non-lifted" VX with little effort.
