33" or 34" tires; any effective differences?

[Riff Raff]

Are the stock 18's fairly light? I still worry about the weight... but 65 pounds for the tires isn't TOO bad compared to most 35"... Thanks for the suggestion!

DBP (David)--- It's my sincere pleasure to help you with any VX wheel/tire questions. Powder-coating wheels is an "art" by itself, and experienced powder-coaters can do literally anything custom and is only limited by your imagination (and $$$ of course). The OEM 18x7 Stock Rim weighs 28 lbs, which is comparible to many aftermarket rims.

A quick word about individual tire weight-- the VX-OEM tire of 245/60R18 weighs only 34 lbs each, so putting on heavy 65+ lbs aftermarket tires is quite an increase in unsprung weight. MPG, launch, and braking distance will suffer dramatically. The tire industry recommends no more than 10 lbs over OEM tire weight-- or in the case of the VX, a tire of no more than a maximum of 44 lbs each to maintain proper safety standards (especially braking distance). Obviously, when selecting massive aftermarket tires the 10-pound safety margin cannot be maintained.

When using heavy aftermarket tires, it's best to increase your following distance from the car in front of you to allow for the increased braking distance required to stop the VX in an emergency panic stop. You will soon discover that having an increased safety cushion of space around your VX will help prevent you from causing a possible rear-end collision and allow you to take evasive action into avoiding a possible accident, especially in today's grid-lock freeway situations which offer little advance warning to brake.

Please keep us posted as your VX plans progress. Welcome to our close-knit family here on VX.Info and to the addiction. Your life is about to change forever after you aquire your VX.

Riff Raff,

I've read many of your posts on wheels/tires as I've been searching about it over the last few weeks. I appreciate your approach. I am aware of the issue with unsprung weight and stopping distances, etc. I have a '70 Chevelle that's a 12 second car in the quarter mile and has drums all around. :-D Speaking of a vehicle that's underbraked... so I'll definitely know to be careful here. Though my usual street vehicles are things that have awesome brakes as I track my cars and motorcycles often, so I will certainly have to get used to it again.

Thanks for telling me the stock wheels weight, too! I've been searching for that for 15 minutes! Sheesh... My biggest worry is all these people talking about busting front axles and stuff like that. So with these 35s, I'll have 93pounds of wheel/tire weight. Man that's a lot... I don't plan on jacking the thing up TOO high, just enough to clear everything, so hopefully the CV's won't suffer too much. I think my current concern in all of this is the weight... I've seen posts of other people saying things like, "Looks cool with those 35s, but let me know when your front axl snaps!" Does that really happen? Yet tons of people wear 33s, which are usually around 60 pounds. Is 5 more pounds really anything to worry about? Thanks,

David

PS, oh yeah, I see you're in Tacoma. Perhaps one of these days we'll have to get together and find some fun places to go! What size tires are you running?

DBP (David)--- Happy to help, and glad to know you're quite wise with a variety of automotive issues and experienced in racing. Sometimes I don't know what level of expertise a new inquirer might have, so I often try to write in very simple terms to communicate effectively-- I meant no offense on my part, and I know you didn't take it in a negative way.

You can count on us meeting someday, and I will make it a personal mission with anxious anticipation. I am in touch with fellow member ROWHARD (Olympia, WA) on a daily basis, so we already have a little PNW grouping. There are quite a few members from the Oregon area as well, and member DON MOORE is one of our most active. If he see's this posting, I'm sure he'll chime in with some sarcastic comment (in true D.M. form).

My VX is 100% Stock "non-lifted" (no TB cranks, with OEM-RS) and I'm running the famous General - Grabber AT2 in P275/65R18 (32" O.D./44 lbs) mounted on the OEM 18x7 Stock Rims. They are absolutely bolt-on perfect due to the OEM rims without any further modifications; although the fitting is extremely tight, and just had to trim a little tiny triangle corner of front inner cladding (very common).

With a little bit more trimming of cladding and a couple of whacks with a BFH, a 100% Stock "non-lifted" VX can still handle a 275/70R18 (33" O.D.) without any lifting and remain at the stock height (no TB cranks, with OEM-RS). It will be extremely tight, but the 275/70R18 (33" O.D.) will still fit without any lifting (only creative trimming & BFH required). I had once considered the BFG - Rugged Trail in P275/70R18 (33" O.D./46 lbs) due to its extreme lightweight, but instead chose the much more aggressive Grabber AT2 for its incredible specifications in every tire catagory while still being lightweight.

Any tire "OVER" the height of 33" O.D., will require some sort of VX "lifting". Perhaps only front TB cranks; depending upon tire/wheel set-up, and then perhaps the addition of taller RS for even taller tires. You'll just have to play with it as you go.

If you decide to go with the OEM 18x7 Stock Rims with LT285/75R18 (35" O.D.); please take copious notes and pictures during the installation, as you will clearly set the new benchmark/standard for the rest who may be considering membership in the exclusive VX 35" O.D. Club (which there are very few current members). I predict success on your part, and would imagine your lead will be emulated many times in the future by other VX members following in your footsteps.

Just to be clear for dbp, that's the front outer corner of the cladding that you trimmed (and is a triangle shape), correct? Or if not, what part of the "inner cladding" are you referring to? I just pressure washed my wheel wells today so I was just looking quite closely at the cladding, liner etc, and am not sure which part you are referring to. Is it this piece?

[Riff Raff]

Yup, that's the exact piece and location of the cladding trimmed triangle. I used the term "inner" (aka inner-side) as in the "interior" of the forward portion of the front fenderwells. Basically, where the front portion of the front tires swing "inward" towards the engine. BTW, nice picture and thanx for sharing!!!
