Lower Gear ratio better mpg?

[JHarris1385]

Without doing any ratio changes of my 10-11% increase in tires...I roll about 15.7 average per tank. I ride 265.75.16. My procomp rims are not too light. I have acheived 17-18 before but the work involved was not worth my time. It concerned acetone.

I don't understand exactly what you mean.

I don't understand exactly what you mean.

There is a recent urban myth about adding small amounts of acetone to gasoline to increase its efficacy.

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

I made a quick little spreadsheet calculator. Here is a preview:

Modify? Improve? Delete?

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.

There is a whole nuther thread on that. I personally raised mine. No side effects. Trust me, before messing with my VX I did the RESEARCH. It works but...the time, and the money spent on the acetone isn't too worth it for me. I have thought about trying it again but have yet to come close. Find the old thread and post questions there.

I called about the DANA 44 kit and it will not work on the vehicross 12 bolt. No other ratio's are available that would make a difference. 4.10 only but would be of little benefit for mpg. Thus ends my quest....

[Triathlete]

There are some options for the rear...4.77 which are rare and hard to find (a pair is for sale now on planetisuzoo.com) and 5.38's from Indy 4x. No 5.38 for the front 10 bolt though...unless you do a SAS with a Waggy D44.

Yes, that is exactly what everyone was trying to tell you originally, and having replaced both my diff's in my garage myself I would have told you this and saved you some time, but I didn't feel you had respected the VX family here, and quite frankly I didn't appreciate your calling out some of our most respected and loyal members, many here consider each other brothers, and you don't mess with someone's brother and make many friends. I hope you can redeem yourself now that you see how tight of a group we are here.

Sounded about right to me...

Well - he did sow the seed -


And reaped his just reward IMHO.

I guess that if there was any semblance of an apology for his rant(s), we could take him under our wing and nurse him through.




Now for the spell check - hmm, looks awlrite.

I've been waiting for this...he CERTAINLY had it coming and deserved it. But frankly the consideration and continued helpful attempts by forum members to contribute to his questions was truly amazing and speaks to the maturity of this group. More often than not, a person who presents himself like this on a forum is flamed relentlessly. Personally I hope he benefits from the whole experience and can become a constructive contributor in the future.
