Title: who runs 225/75/R16's
Post by: Maroon Monsoon on July 12, 2006, 04:30:38 PM
I have a 2000 GV and am pretty well set on some kumho road venture MT's in this size. just wondering what gas mileage loss and power loss people have with them as well as how the clearance is whith certain lifts. I have boondox coil spacers and my up travel is currently limited by the struts and shocks so for up travel there is extra room. I am wondering about turning (pretty sure it won't be an issue) and the clearance between the back of the rear fender

thanks

with 31's (245/75R16) i get approximatlely 290 miles with a full tank with a low restricted mufller

i dont think you'll be hurt much by 29 inch tires.

I thought the 225/75 was a tadd taller than 29.

Mine are 29" even with the weight of the vehicle on them.  Power loss is minimal and mpg is down about 1-2 in all conditions.

Hi,

i run also 225/75/16 BFG AT's in my 1600cc GV, for over 6 months now.

They run pretty nice with the 5,12 r&p i have, but note that i also use Iridium spark plugs, and the fuel booster system, which is very good!!

I can have about to 465+ klm (80% on- 20% off) with a full tank.
It's not a big deal i think.

Vasilis.

my GV has a 5 speed manual which I freaking love to pieces. sounds like these 29.3's I'm looking at will be pretty nice. losing a mile a gallon is tolerable. I probably could use a new set of plugs and I get 22-23 miles a gallon in town! plus my air filter really needs cleaning. doing the two things will hopefully make the mileage where it is with the new tires. might not need a new set of plugs but I need to check soon

Hi,

I run 225/75/16 too, BS M/T. My GV is 2.0 5 Dr A/T with 3" suspension lift, steel bumper, 6000 winch, and some skids. Stock R/P and rims. Only 7~8km per liter and feel powerless.

1" wheel spacer is added or, will rub the chassis when turn to dead end.

that is a cool site. so yours is the 2 litre with an auto trans. hoping that and the hevy bumper and winch is most of why you have no power. thrash says he gets 290 miles a tank with 245's or something like that and he has a 2.5 litre.

that is one sick GV you have. I've seen pics of it before, loving it. what kind of lift did you use? did it use longer struts or mount spacers or strut extenders?.. anyways, sick vit

Thanks the_maplebar, Maroon Monsoon, and blacknight.

Maroon Monsoon,

Mine was 3" suspension lift with Japaness BBlanks springs, struts and shocks. It's a longer strut. But I had bought the Calmini 2.5" kit and now fitting it and hope can fininsh at this weekend.

blacknight,

A local shop ordered the bumper from Taiwan for me about 3 years ago, I don't think it's FTS4x4. I'd contacted some shops in Taiwan through internet but no reply or just 1 or 2 email then lost communication. ??? >:(

is that longer strut avaliable in the US? if so I'm getting a set of those when my ome's blow out. I would imagine they are cheaper and better. my ome's are just a touch softer than i'd like.

why are you putting the calmini kit on? have you thought about maybe still using the 3 inch lift coils with it? seems like your lift is better than calmini minus the stock control arms. if it were me I'd just put the control arms on and not sure what else.

happy modding

Are you going to keep your 3" springs ???  I'm useing VTTR 3" lift springs with my Calimin kit. The ride is better with VTTR springs.

I hope can use my poor English to say it clear.
The current suspension kit was installed by the mod shop. I belived that the longer strut made the camber changed, the shop just drilled the bottom hole of the strut bigger to adjust, the result was the camber changed always because the hole was too big the bolts could not hold the camber in the fix point, so bad handling and made tires worn out. On the other hand I want the Calmini's A-arm and the heavy duty springs for front 'cause the winch and steel bumper, people say that the Calmini's is designated to fit with winch and bumper, so the spring and strut are stiff, that's suitable for me I think. I will install the whole Calmini kit to have a try first, to compare with the BBlanks then cosider what to do.

I will install all the Calmini kit first to compare with my current use BBlanks. May be different from you my front is very heavy. The front height was 1.5" lower after fitted the bumper and winch, I had put a 15mm coil spacer on it to raise up the front. But i think the Calmini front will be lower than now for 1/2 to 1 inch.

yea, I was just going to say you should add some coil spacers to the calmini to make it a 3 or 3.5 inch lift. I don't know how big in inches 15mm is but I imagine about a half inch. maybe some good high density uhmw plastic 1 inch spacers for a good 3.5 inches of lift in back and about 4 up front. might want to drop the diff a little more depending on CV angles if you do that

good luck

The fix for that is to put washers between the bolts and the struts, and weld them to the struts once it is adjusted correctly.

that's a good idea. I'd only tack them though if it were me. I heard that shocks are kind of sensitive to heat and explode when too hot

Yes, that sounds right.

25.4mm = 1in so 15mm = 0.590551181 in   ;D   which should give you about 0.8858267715000000000155101764764964400456 in. of lift in the front  ::)

I would say 15mm = 9/16". :D

Thanks IanL and Maroon Monsoon for your good idea and comment.

I think many GVs had fitted the Calmini lift kit and add a spring spacer on front, would someone tell me will the camber be changed?

Thanks!

the control arms are supposed to maintain proper track width and camber but when you add a spacer to it that all changes. track width isn't that big of a deal especially with a calmini arm seeing as how you are now doing 3 inches of lift with stock arms. you'll probably want a set of camber bolts when you do the calmini with coil spacers and get that thing into an alighnment shop after you let it settle into the spacer a bit
