Standard Tyres are 205/75/15 which are 27.11 inches in rolling diameter.
The largest size people seem to have fitted to an unmodified Jimny is 215/75/15 which are 27.7 inches in rolling diameter.
With a 2" lift you can go to 235/75/15 which are 28.8 inches in rolling diameter, some trimming of the wheel arches may be necessary.
With a 3" lift you can go to 265/75/15 which are around 31", again trimming is required
is this the info you need??
what year jimny you looking at? and waht other mods??

Just remember, suspension lift doesn't allow bigger tyres to be fitted.
You must ALSO fit bumpstop extensions, otherwise, the axle can still travel just as far up into the guard, and the bigger tyres will now scrub.

hey cheers for that. 27" doesnt seem very big at all. im looking at a 2005 model. i was hoping that i could lift the suspension by 2" and be able to put 30" maxxis bighorns on. what do u reckon is the best thing to go with. i want it to have big tyres on it but i dont want to lift it heaps. do 27.7" tyres look big on a jimny?

bingo Spike.
Another huge variable is tyre and rim width and backspacing.
You're never going to clear a 32 X 11.5 on a 3.5" backspaced 8" rim with almost any amount of lift/trimming, but a 32 X 9 on a 4.5" backspaced 7" rim will go on with no visible trimming (lots behind the plastic) no lift and about 2" of bumpstop spacing.

i think ill have to go with the 2" lift and put 28.8" tyres on with bump stop extensions. maybey ill lift the body a bit too. give me some ideas boys. i want it to look better then stock pretty much straight away. without having to spend any more than like 1500, 2000 at the most.

alrighty then. two questions. firstly wat is 4.5" backspaced 7" rim. that could be a stupid question. also what do u guys think is the easiest way of getting bigger tyres on stock 2005 jimny. cheers

7" = width
4.5" = the distance from the back of the rim to the mounting face.
It's more commonly called offset, but backspacing is what's important for fitting a tyre, and effects where what rubs on where. Offset is harder to figure out, but is what wheel manufacturers use.
Personally, I'd stop at a 215 on your standard rims unless your jimny is automatic, or you don't drive it offroad.
You can get to a 235/75/15 fairly easily (trimming) but this will effect your gearing and that's harder to fix on a jimny than a sierra. If you are auto, you can cheat a bit more tyre as the auto will cover up the gearing problem, and if you don'y go offroad, the lack of low range gearing won't really hurt you.
215's work well all round though.
Also, jimny's have much more complex bodywork than sierras (for example) and very small wheelarches. unless you are comfortable taking to your car with a grinder, I'd stay away from the larger sizes.

the gearing can be fixed with 4:16 gear set put into a sirra t/case i think this will let you run 31" but your speedo wont work (there are ways to fix this just cant find the info)
and there is someone that makes gears for the jimny t/case when i find the link for this ill post it for you

Which is true dangerousdog, but that's going to cost at least $1K to do from scratch, without sorting the speedo.
Also, DG tuning and Apio make different transfer sets for the jimny case, and they can be combined - as one does high range and low range equally as it's a chain and sprocket set (DG) and the APIO set lowers low range only as it's the planetary.
Once installed, it's very clean and works beautifully (speedo still runs etc), but these kits, as they are from europe/japan are expensive to land here.
It didn't seem that either/or these options was feasible for Middo based on his budget.
In regard to "sunraysia" rims, I assume you mean you want white 8 spoke rims. There's no reason to buy new rims to run 215's. (and I wouldn't) but you'll need to keep this information in mind when you go buying rims:
0 offset means the distance from the front of the rim to the mount surface and the back of the rim to the mount surface is is equal.
10P means theres 10mm more "dish" at the back than the front
25P means there's 25mm more "dish" at the back than the front.
you'll need to try and match grand vitara specs for the easiest fit, which means the ROH track II gets the nod as the best rim (It's also the dearest and best quality)
Model Rim Size Offset
Sierra 15' x 5.5" 10P
Vitara 15" x 5.5" 25P
Vitara 2.0 V6 16" x 6.5" (alloy)
Grand Vitara 16" x 7" 5P
Jimny 15" x 5.5" 5P
Speedy Desert Rat 15" x 6" -3
Speedy Desert Rat 15" x 7" -15
Speedy Desert Rat 15" x 8" -28
Speedy Desert Rat 16" x 7" 0
ROH Trak II 15" x 7" 3P
ROH Trak II 15" x 8" -10
King 16" x 7" -13
If you are prepared to cut stuff, space your bumpstops a bit and temporarily live with crappy gearing, you could try for a 235 75 15 or 30 9.5 15, but you will really need gearing eventually.
