Fat fat fatties

If you notice in those pix, the car is slammed to the ground and I have NO issues what so ever with clearance. Without major modifications to the suspension you can not go any lower than what my car is in those pix, and I have absolutely NO issues with anything hitting. I drive the car all the way down and can make full turns with no problems and the tires do not rub ANYWHERE at all.....hope that helps....:D
 
rich do you rember my car, stock sized rims (off a t bird sport exactlly the same size as the cars original octastars) and 245/50/16 tires no probs up or down

hi ray long time no see did you get your puter up and going yet?

On the stock rims I think 245 or 255 are the biggest you can put on. I am currently running 245/50/ZR16 inch Yokohama Avid V4s all the way around, and I like the look.......well, I did when I was driving it.......will hope to again soon.

aside from the stock rims, whats the fattest you can go? (talkin rears only)

Today my store just got these killer crager knock offs. I got someone to take a pic of em and im gonna photoshop em on the mark to see what they look like. If they look good ill prolly look for a set that can hold some meet.

Which one's? The one's I have?


now im no body man by far nor do i pretend to be, so im gonna ask a stupid question (no comments please)...what are you refering to when you say lip? the lip on the body pannel itself?

This is what I mean. Cutting the rolled fender lip up to the pinch welds for more MEAT!

It seems I have more clearance after ROLLING my lips over cutting the lips up to the pinch welds. Not getting cocky just an FYI..

..another FYI... with a slammed mark viii you can't fit any wider than an 11.5" tire under the wheel wells, unless you're mini tubbed.

305.. 295.. 285.. doesn't matter. size varies from manufacturer to manufacturer by ALOT.

I have BFG 275's and they're 11.5" wide exactly. Letters rub on the inside above the shock mount and with rolled lips, (as I said which APPEARS to give more clearance than the cut) ..I still had to trim my bumper cover to not rub, and I have maybe 1/16" clearance.

I cut til I quit losing paint.

I tell ya.

11.5" MAX, unless you're ridin like a freakin truck. :)
 
My 265s on 9.5wide18s say 10.7" thread. I rolled my lip also and rub the BC still just a smidge once in a blue moon. Could trim it that 1/16 looks like a 1/4 would be needed on mine, doesn't do it enough to care.

I have 255/50 Falkens on my stock 16x7 snowflakes. They're a little under .6 inches shorter than the stock 225/60 and will throw the speedo off by a little bit. 245/50s would be shorter still (albiet by a tiny amount.) Unless you go with a real tall tire 255s are probably the widest that will work with 16x7s.

What would be better 255 or 245? The offset on the speed would that be up or down? Meaning would I be showing faster of slower on the speedometer?

Smaller spins the speedo faster than you are going.

Good way to avoid speeding tickets.

LMFAO!
 
Hmmmm.... but at 90 to 100 mph I don't think it would matter if the speedo was a little off... I'd still get the ticket. LOL...

But setting the cruise on 60 would mean I'd save a lot money on gas.... the conservative side (hear that Bryan, I have a conservative side LOL)...
 
With the stock gears and speedo gear 245/50s will mean when you're actually going 65, the speedo will say 67.495. 255/50s will mean when you're actually going 65, the speedo will say 66.474.

Ground clearance will be reduced from stock by .3" for the 255s and .5" for the 245s. If you're lowered this might make a difference.

Now since the 245s are shorter it means it takes less force but more RPM to turn the tire compared to the 255s (or stock 225/60s for that matter,) making it effectively like running 3.17 gears instead of 3.08s (or about 3.38s if you have an LSC w/3.27s.)

So your car would be a little faster with the 245s - except you have less contact area so if you're already traction limited on launches then you won't be able to hook up.

255s will take up more of the wheelwell than 245s, so when you look at the car from the side 245s might look a bit small for the size of the car. I looked at 245/50s or 255/50s when I got tires last month... I figured 255s were the way to go.

I'd do the 255/50s to if I rode stock wheels.


Very technical by the way...I like that:) :).

I agree... very good and helpful... Thanks MediumD... I'm still not sure which one I'll be getting... but it will be either the 245's or the 255's.... I love the fat tire look and I love having side walls... I can't stand the Wagon Wheel look of large rims... and Low Profiles to me just don't make it. No wall for corners, and what about those Norhtern pot holes that our great snow plows help form. Or in Debi's case my curb LOL....
 
I have 245/50's, but will probably go with 255's next time. And yes the speedo on my car is off by about 3 mph.
 
Width has nothing to do with the speedo.

You can have 255's that make you read way fast and you can have 255's that make you read way slow.

255/40/18

255~ width in (mm)

40~ % of width

18~ size of wheel the tire goes on.

Everybody should know this...... :rolleyes:

Variations in treadwidth between tires with the same aspect ratio will cause a variation in the tire height, and thus the speedometer reading. We were talking about 245/50/16 vs 255/50/16. So quit rolling your eyes before I poke them with a stick.
 
Forget the Mathmatics in the size of the tire for a moment.

It is VERY common for manufacturers to produce tires that are not exactly X-Height according to the sizes equasion. Imagine that....

So YES...Width in turn with height can be skewed among manufacturers and even among styles/models in the same manufactuers stable of tires choices.

True. However, that is a variable that's pretty well impossible to pin down and compensate for.
 
What plays a bigger part in the whole idea of Huge rear tires is the offset of the wheel. You have to start with A before you can talk about B...

PoniesViii is sporting wheels with a +36MM offset and is at the limits on the outer fender clearance...How much room is left inside Chris???

I bet that with a custom built wheel you could play around with it and run a wider tire yet. However finding a wheel that suits the sweet spot of a Lincoln MarkVIII front and rear in a cast wheel is gonna be rare as hens teeth.

Personally I think a 275-40-18 is perfect since it is stock height and plenty wide as well.


Brad
 
The letters on the inside of the tires rub the dust off right above the shock mount.. with camber fixed! So minute that you can't tell the letters rubbed at all looking at the tire.

I'm maxxed out on width for sure Brad. I trimmed the b/c and rolled the lip to the maxx as explained and if I didn't do that they'd be too wide on the outside as well. Keep in mind my car's so low that you can't see the tops of the tires when at park height.

Can't ask for a better fitting wheel/tire combo for the rear of a mark in my opinion. (275/40 BFG, 11.5" wide exactly, saleen speed star 18 X 9) ..those BFG's should be considered 285's comparing to other manufacturers I think. but after modding I don't rub at all, except for that dust! lol.
