will 30/9.5/15 tire fit on 2000 tracker with a 2 1/2 body lift? Will they rub or can i go bigger?
Like 31/10.5/15
Rims will b 15"/8"wide/ 4"of back spacing 5 on 5.5 bolt pattern

you'll be rubbing for sure - there's no way you won't. i just put a tire that stands about 29.5 inches tall and 8 inches wide on my '02 vitara after lifting 3 inches. they JUST fit at full flex into the wheel wells and the front tires rub the frame when turning. the turning radius has definetly been reduced with the stock rim.. a 9.5 inch tire will get a whole bunch more rubbing. you could get a rim with a deep offset to push those tires out and away from the frame, which would help. the bigger the tire the bigger the change in the gear performance as well. you mess around with the crawl ratio which you'll definetly notice off roading and when accelerating - the truck is more sluggish. the speedo and odo are no longer accurate. bigger tires also mean that all the components to which they are attached - ultimately everything - is suddenly smaller in comparison. that means that parts are going to wear faster and are going to break easier when under stress. when wheeling, you start snapping axles, cvs, hubs, steering parts, pinions, transfer case parts, etc, etc, etc. just things to think about... its definetly not the case that bigger is always better with tires and lifts when considering performance and longevity. if you want parking lot flash and don't care about real performance then you could probably find a way to jam 32 X 10.5 inch tires with a 2.5 inch lift but you'll hate driving it. my 2 cents.

 it would be close, a 30 inch tire may fit with a body lift that big, but you may want to think about a mild susp lift to go with it as well. it kind of depends on the tire itself, it may be a 30 inch, but only measure out to 29 or so....


i ran  245/75/16 MT/R's on my grand vitara with a 1.5 inch body lift and a 2 inch susp lift on stock rims  with only enough rubbing on the frame to rub the paint off, but not even enough to hear....

does your truck have 16" rims on it now? i only ask because if it does,  the 15's wont fit. if you do get a rim with a larger offset, you will clear the frame, but may rub on the fenders when you steer if you push it out too far.

btw, i run 33X12.5 on my xl7 and love it, and you dont have to worry about your axles or gearing with a 30" tire its not that big once you go with a 31 or larger you will notice, but its not that bad.....

oh and bigbadshawn,  you may want to find a low rider site to join.  if your that worried about power, and breaking axles, cv's and t-cases..... its just a 30 inch tire LOL

i don't understand your low rider comment, but i'll assume you were trying to be funny. so - ha ha. good one! all i am saying is that you are playing with fire when you put a tire on a truck that is much larger than it was designed to handle - unless you beef everything else up on top of it. menis asked about 30X9.5s or larger, such as 31X10.5s. these tires are significantly larger in diameter and width than stock. i explained that this is enough to get into trouble with - especially off road. i have seen it happen many times - guys go and get the biggest tire they can possibly fit into their wheel well, hit the back-country and then end up doing the repairs because of it. i'm one of them, i've learned the lesson. i dare you to wheel that xl7 with 33X12.5s with any degree of intensity. you're going to find the weakest link. it won't be long until you hear the heart-sinking snap. unless you've beefed up the rest of the system - which is expensive and involved. this is basic stuff. but if all you want is parking lot appeal, no real problem. and that is what a lot of guys want, but don't want to admit it out loud. i don't hold that against them.

31's have generally been the max stock zuk axles can handle (I'm talking 22 spline sami & first gen trackers).  but most will run 32 and 33's

My XL-7 has 28 spline rears and 26 spline fronts.

I am not concerned one bit about breakage.

We run 36's on Toyota axles 30spline (stock ) with out first gen tracker in rocks, never had an issue.......

I'm just saying why be scared of  "what could happen" .........

4 wheeling is a motorsport, and like anything, you have to pay to play, shit happens...........

Sure, I agree there is a responsible limit to tire size vs. axle weakness , but that is what research is for.

He wont be the  first or last person to run 30 or 31's successfully.......... 

all my point was,  there is no need to scare him off entirly (it was his first post after all)

I run 31's, have been on my XL-7 and GV for over a year, no problems on or off road. And I don't drive the XL with care either, I use it like a truck should be used, mud snow, whatever. Unless you're rock crawling, you will have no issues. My XL actually feels better with the larger tires thank it did with the stock ones. DO IT.

I had 31 muds on my 99 tracker with a 2" body life, worked great

when i went from 33 x 12.5s to 35 x 12.5s on my 76 landcruiser i started going thru drivetrain parts on the same terrain as before. rear pinion was the first to go, two birfields, then t-case housing. that is why i am now going to go back to 33s. there is a point where tire size becomes a problem.

anyways, i agree, go with the 30 inch tire! i just threw a set on my 02 vitara and had it out wheeling this weekend. it was a dramatic improvement over stock. i was totally impressed with the truck. and i didn't snap any drive train parts... yet.
